Barbara Hedeler at Chalmers examines how national innovation policies can make a difference and uses three Nordic examples to pave the way for policymakers to accelerate the transformation.</b></p><div>​The Paris Climate Agreement is extremely clear: extensive carbon emission cuts are crucial in the coming years. This requires fundamental changes in all parts of society, including the established industry. </div> <div> </div> <div>Policymakers have an important role to play in accelerating the transformation of the industry towards emerging technologies such as biofuels, hydrogen, and electrification, and governments must provide direction and incentives for change. But even so, there is still much uncertainty about the role of policies for industrial transformation and the creation of new value chains. </div> <div> </div> <p class="chalmersElement-P">This is what Barbara Hedeler has tackled in her doctoral research, which she now presents in her licentiate thesis. An important goal is to provide a basis for the development of innovative solutions to policy design.</p> <div>“Better knowledge about the possibilities and limitations of innovation policy to influence the transformation of the industry has high practical relevance. I hope this research can contribute to a greater understanding of the opportunities and challenges for national policymakers to accelerate industrial transformation in global contexts”, she says.</div> <div> </div> <h3 class="chalmersElement-H3">Examines policy mixes in Sweden and Finland</h3> <div><p class="chalmersElement-P"><span><img src="/sv/institutioner/tme/PublishingImages/Porträttbilder/BarbaraHedeler.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><span style="display:inline-block"></span></span>Barbara Hedeler highlights that governments worldwide increasingly try to combine domestic industrialization goals with large-scale systemic changes in the industry to decarbonize existing production processes. This is neither easy nor a quick fix.<br /><br />“From past technological developments, we know that changing existing socio-technical systems is difficult and usually takes many decades”, she says.<br /><br />In her thesis, Barbara studies three different examples of past industrial transformations in Finland and Sweden, thereby providing knowledge about how policy mixes can affect change processes in industry.<br /><br />“We found that how policies are designed and changed over time has large effects on how different actors are motivated to participate in such transitions. As part of this, we found five types of value chains that describe how national actors are typically integrated into global value chains – from importers of renewable energies to domestic technology developers and producers. We also explain the role of national policy in the development of these different types,” she says.</p></div> <div> </div> <h3 class="chalmersElement-H3">A supportive environment for Ph.D. students</h3> <div> </div> <div>In her future research, Barbara will continue to examine the link between innovation policy design and industrial transformation. She enjoys being a Ph.D. Student at Chalmers and the division ESA (Environmental Systems Analysis) and appreciates that it allows her to experience different parts of academia, including research and teaching.<br /><br />“The Ph.D. research school puts great weight on our development into researchers with regular workshops on different aspects related to social sciences, such as theory building or text-based discussions. Overall, it gives a chance to become part of the academic environment here at Chalmers, but also internationally, and to meet many inspiring people along the way” she says.<br /><br />At the same time, she notes that being a Ph.D. student has its ups and downs.<br /><br />“You must acquire a lot of knowledge and skills within a fairly short time frame. But it really helps to be part of the research group at ESA and in the department and exchange ideas and learn together with other Ph.D. students. My supervisors are also great and always lend a helping hand when needed”, she says. <br /><br /></div> <div> </div> <div> </div> <div><em>Text: Ulrika Ernström</em><br /><em>Photo: </em><em>portrait</em><span><em> Carolina Pires Bertuol, genre photo <a href="https://unsplash.com/%40marekpiwnicki" target="_blank">Marek Piwnicki</a> on <a href="https://unsplash.com/s/photos/industry?utm_source=unsplash&amp;utm_medium=referral&amp;utm_content=creditCopyText" target="_blank">Unsplash</a><a href="https://unsplash.com/s/photos/industry?utm_source=unsplash&amp;utm_medium=referral&amp;utm_content=creditCopyText"><span style="display:inline-block"></span></a></em></span><br /></div> <div> </div> <div><br /></div> <div> </div> <ul><li>Barbara Hedeler is a Ph.D. student at the Division of Environmental Systems Analysis, at the Department of Technology Management and Economics, Chalmers.

Finding unexplored opportunities for green innovations, entrepreneurship and new jobs in coastal communities is something that Robin Teigland is passionate about. As a professor of Management of Digitalization, she will talk about the &quot;blue circular economy&quot; during this year's William Chalmers lecture on 3 November.</b></p><div>​The word <em>net</em> can be used in many contexts. A fishing net, a network of people or a digital net.

But the resources can be what we call 'trapped resources'. In Portugal, old fishing nets are indeed a trapped resource. After being used, they are thrown away or burned, although they are still really valuable. So how to unleash these confined values? What we do is merge technology where you grind down the used fishing nets, which are turned into pellets that can be used to 3D print new products, on site, for a need that the local community has.&quot;<br /><br /></div> <div> </div> <div> </div> <div> </div> <div>Robin Teigland continues with another example:</div> <div> </div> <div> </div> <div> </div> <div>&quot;Fishermen may only be able to fish for a certain number of months of the year, because they have a certain quota system. But what if they could use the other time to fish for ghost nets, i.e. abandoned fishing gear on the bottom? Or map ocean data with their boats? It's about thinking differently about the resources that exists.&quot;<br /><br /></div> <div> </div> <div> </div> <div> </div> <div>By starting from the challenges that exist, it is possible to identify what needs and possible resources can be used. Then you use both digital and human networks to realize it, in the form of innovations and entrepreneurship.</div> <div> </div> <div> </div> <div> </div> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> </p> <h2 class="chalmersElement-H2">How to become an opportunity maker</h2> <p class="chalmersElement-P"> </p> <div><p class="chalmersElement-P">During her lecture on 3 November 2022, Robin Teigland wants to underline the importance of the matter for our future.

Students are being introduced to key themes connected to Sustainability, Entrepreneurship and Innovation, with perspectives from multiple stakeholders.</b></p>​&quot;Sustainable Entrepreneurship and Innovation is a topic which attracts students throughout Europe to this course. Entrepreneurship and innovation is not necessarily sustainable by default – there is a large need for better tools and insightful reflections, to help shape more sustainable futures&quot;, says Karen Williams Middleton, Associate professor at the Department of Technology Management and Economics, and course examiner of the new summer school at Chalmers.<br /><br />The initiative is created within the ENHANCE alliance of technical universities and is a part of the Tracks courses at Chalmers. Before and after the intensive week in late August, the students carry out academic research in teams, with the aim of creating value in a sustainable manner for people around Europe, and the planet as a whole. <br /><br />&quot;The group of PhD and master students from our seven ENHANCE partner universities came with huge interest, engagement and challenging questions to Gothenburg for the in-person week. We designed the course to include several novel approaches: interviews with sustainable entrepreneurs; synthesis of individual interviews in a group format; lectures by researchers, institutional players, and entrepreneurs; student-led sessions including workshop facilitations by students; and field trips to exemplary initiatives in the Gothenburg region. This all aimed to familiarize the technical students with four main aspects relevant to sustainable entrepreneurship and innovation: systemic, value creation, collaboration/teamwork, and funding&quot;, says course leader, Yashar Mansoori, a post-doc working with ENHANCE at Chalmers.<br /><br />One of the students was Arpita Chari, PhD Student at the Department of Industrial and Materials Science at Chalmers:<br /><br />&quot;I applied to the course because I was interested in innovation and entrepreneurship when it comes to business strategies with respect to sustainability, especially the aftereffects of the covid pandemic. I also wanted to apply the skills garnered from the summer school to industrial level issues after I graduate from my PhD program.&quot;<br /><br />&quot;Considering that this was the first time the course is being run, I think it was very well designed and structured. The themes were relevant, and all the lectures and workshops were thoughtfully connected to the themes. I liked that there was one main academic lecture, one policy/legal lecture, one talk by a sustainability entrepreneur and then the student-led workshops each day. This mix of content enabled a rich learning experience&quot;, says Arpita Chari.  <br /><br />Professor Mats Lundqvist, Chalmers’ Vice President of Utilisation, is pleased that the university can offer this course, and adds:<br /><br /><div>&quot;Student from all over Europe express interest into how we at Chalmers and in Sweden take on sustainability challenges. The Northvolt and Volvo initiative around battery innovation, where Chalmers is highly engaged, is an inspiration for European leadership in Sustainable Entrepreneurship and Innovation&quot;, he says.</div> <div><br /></div> <div><span><img src="/sv/institutioner/tme/nyheter/PublishingImages/summerschool_field_750x340.jpg" alt="Summer School in Sustainable Entrepreneurship and Innovation" style="margin:5px 0px" /><span style="display:inline-block"></span></span><br /></div> <div><em><br />Text: Daniel Karlsson</em></div> <div><em>Photo: </em><span></span><span><em>Karen Williams Middleton</em><span style="display:inline-block"></span></span><span style="display:inline-block"></span><span style="display:inline-block"></span></div> <br />Read more about the <a href="https://enhanceuniversity.eu/" target="_blank">ENHANCE alliance</a><br />Ream more about <a href="https://student.portal.chalmers.se/en/chalmersstudies/tracks/Pages/Tracks.aspx">Chalmers’ Tracks courses</a><br /><br />Thu, 01 Sep 2022 11:00:00 +0200https://www.chalmers.se/en/departments/tme/news/Pages/Chalmers-and-Ikea-spur-innovation-in-sustainability-with-a-competition.aspxhttps://www.chalmers.se/en/departments/tme/news/Pages/Chalmers-and-Ikea-spur-innovation-in-sustainability-with-a-competition.aspxChalmers and Ikea spur innovation in sustainability with a competition<p><b>​Gamification to raise awareness of global sustainability, reuse of old furniture through the Ikea website and 3D-scanning to discover damage to returned furniture. These are a few of the ideas coming out of the Innovation Challenge, where Chalmers students developed innovations that could transform both Ikea’s products and their business operations.</b></p>​In a rapidly changing world, business and academic partnerships are becoming increasingly important. This is also true for a company like Ikea, which is looking to help secure a good foundation of competence among young talents to help tackle future challenges in retail, supply chain logistics and product development, to name just a few. <br /><br />This year, Chalmers University of Technology and <span>Ikea<span style="display:inline-block"></span></span> Supply collaborated in a new competition among students: Innovation Challenge. Here, students from the Industrial Engineering and Management program integrated theory and practice to conceptualize digital innovations to help <span>Ikea<span style="display:inline-block"></span></span> fulfill its vision of a more sustainable and circular future. Approximately 120 students were divided into twenty groups. The students presented their ideas for each other and a jury with Innovation Leaders at <span>Ikea<span style="display:inline-block"></span></span> Supply Development and Innovation Networks, who then selected three winners. <br /><br />Innovation Challenge also represents an opportunity for Chalmers students to get a first experience of real working life:<br /><br />“We designed the Innovation Challenge to enable our students to take the classroom into the real world and work on challenges that companies are facing today.

In the fish industry, over half of the weight of the fish ends up as side-streams which never reach our plates. This takes a toll on the environment and is out of step with Swedish food and fisheries strategies. Now, food researchers at Chalmers are introducing a new sorting technology that means we get five good cuts from fish and not just the fillet. A herring processing plant on Sweden’s west coast is already implementing the new method. ​</b></p><p class="chalmersElement-P">​<span>When the fillet itself is removed from a fish, valuable side-streams remain, which can be turned into products such as nuggets, mince, protein isolates or omega-3-rich oils. Despite such great potential, these products leave the food chain to become animal feed or, worst case, get discarded. To exploit valuable nutrients and switch to more sustainable procedures, the way we process fish needs to change. </span></p> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">All cuts are treated with care</h2> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2"> </h2> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2"> </h2> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2"> </h2> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <p class="chalmersElement-P">&quot;With our new sorting method, the whole fish is treated with the same care as the fillet.

The backbone and head are most muscle-rich and thus well suited to becoming fish mince or protein ingredients. As the belly flap and intestines are rich in marine Omega-3, they can be used for oil production. The tail fin has a lot of skin, bones and connective tissue and is therefore well suited to such things as producing marine collagen, a much sought-after ingredient on the market right now. In addition to food, marine collagen is also used in cosmetics and ‘nutraceuticals’, with documented good effects on the health of our joints and skin.</li> <li><span style="background-color:initial">The EU’s fish processing industry is significant and generates an annual turnover of nearly €28 billion whilst employing over 122,000 people. However, the industry faces several challenges. For instance, an estimated 1.5 million tons of seafood side-streams are produced in Europe, based on a production of 5.1 million tons of fish caught. In Sweden, it has been estimated that 30,000-60,000 tons of seafood side-streams are generated yearly; some 35-70 times more than the Swedish cod catch. This means that the current utilisation of aquatic biomass for food is far too low. When producing fillets, up to 70 per cent of the aquatic resources end up as side-streams, which are either used for low-value products such as animal feed or discarded, which takes a toll on the environment and sometimes also the companies involved.</span></li></ul> ​<br /> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div>

This is shown in a new study from Chalmers University of Technology. To promote the construction of larger systems and solar-as-a-service, changes in regulations are required. Such changes in regulations can contribute to the national goal of reaching one hundred percent renewable electricity production by the year 2040.</b></p>​In recent years, the market for self-produced solar energy has exploded in Sweden. The reason is, among other things, high electricity prices and the ongoing climate change. But for those who do not have a roof of their own or the financial conditions to invest in a solar system, the alternatives are limited.<br /><br />&quot;If we are to be able to increase the amount of solar energy in Sweden, we must ensure that more people have access to solar photovoltaics, not just those with detached houses who can afford to buy a system&quot;, says Amanda Bankel, doctoral student at the division of Innovation and R&amp;D Management at the Department of Technology Management and Economics, Chalmers University of Technology.<br /><br />The new study by Amanda Bankel and Ingrid Mignon, Associate Professor at the same division, has been published in the scientific journal Energy Policy. It shows that there is a lack of agreement in how researchers, policymakers and firms view solar business models. For instance, “community solar” business models have received much attention in research and policy at, for example, EU level. Community solar means that many people come together to produce, share, and consume renewable energy locally.<br /><br />However, such business models are hardly found among solar firms on the Swedish market. This does not imply that there are no energy communities in Sweden – only that firms do not see the need to design their business models for these customers. If Swedish policymakers want to increase the amount of solar energy through energy communities, they must also understand how firms that offer photovoltaic systems reason and what motivates them to specifically target energy communities, says Amanda Bankel.<br /><br />Other solutions that make it possible for customers to buy solar energy as a service through, for example, leasing, are also scarce in Sweden, despite having had a major impact in other countries, such as the US.<br /><br />&quot;Swedish policy instruments have favoured small-scale systems where the person who consumes the solar energy is the same one who buys and owns the system. Hence, it is not surprising that we see many firms offering these solutions and only a few that are aimed at people who do not want, or have the opportunity, to invest in their own system.&quot;<br /><br />&quot;If Sweden is to achieve its goal of 100 percent renewable electricity production by 2040, policymakers should ensure that more people have access to solar photovoltaics by promoting different types of solutions&quot;, says Amanda Bankel.<br /><div><div><br /></div> <div><img src="/sv/institutioner/tme/nyheter/PublishingImages/AmandaBankel_600.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:300px;height:450px" /><img src="/sv/institutioner/tme/nyheter/PublishingImages/IngridJohanssonMignon_photoLaurentToudic_600.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:300px;height:450px" /><br /><br /><br /><br /><br /></div> <br /><div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em>Amanda Bankel and Ingrid Johansson Mignon.<span style="display:inline-block"></span></em></div> <br /></div> <br /><strong>About community solar</strong><br />Community solar involves many people coming together to produce, share, and consume renewable energy locally.

The isomer can then be stored in liquid form for later use when needed, such as at night or in winter. The researchers have refined the system to the point that it is now possible to store the energy for up to 18 years.

How do you communicate in a clear and unbiased way, what information to include or to exclude, how do we coordinate across chapters so there is consistent and no overlapping messages, etc.”, says Sonia Yeh, Professor of energy and transport systems at Chalmers University of Technology. </div> <div>Her expertise is in energy economics and energy system modelling, alternative transportation fuels, sustainability standards, technological change, and consumer behavior and mobility. She has contributed to IPPC report, Working Group III Mitigation of Climate Change, Chapter 10 Transport in the subchapter “Scenarios from Integrated, Sectoral and Regional Models”.</div> <div><br /></div> <div><strong>What is it that makes you take on such a big assignment like this?</strong></div> <div>“On one hand, it is indeed a huge time commitment. So, one must decide beforehand how much time one can spare to be involved in such a big effort. On the other hand, it is a huge honor as a scientist to be selected to represent your country to co-produce such an important document. The document is the most comprehensive assessment effort roughly every 6 years providing an update on climate mitigations options. It has tremendous societal values to both policymakers and all concerned citizens around the world”, says Sonia Yeh.</div> <div><br /></div> <div><strong>Her path to be selected</strong> as an IPCC contributing author was a bit unconventional. The typical path for being an IPCC author was for one to first self-nominate, then being selected for nomination by your country. <br /><br /></div> <div>“I joined the IPCC process in the middle as I received a phone call one day by the lead author of the chapter on transport scenario asking if they can rely on my competence in the long-term projections of transport scenarios. That’s how I joined in the middle of the process. So there is a separate path to be asked to join as an contributing author if the lead authors consider your technical expertise is critical for part of the report”, says Sonia Yeh.</div> <div><br /></div> <div><strong>What sets this report apart from previous reports?</strong></div> <div>&quot;I cannot talk about any specific details before the release. But certainly, one of the most interesting things writing up this report is to observe how things have changed from this report from the last (5th Assessment Report), which directions and how fast the changes were. Lots of things have changed: technology costs and their commercial availability, demand growth, new technology, system level interactions, etc. As someone said, around the time of the last report, we were talking about the transitions. At the time of the writing of this report, we are right in the middle of the transitions. So we are certainly seeing lots of changes (both expected and unexpected) so that would be something interesting to watch out for when the report is released&quot;. </div> <div><br /></div> <div><strong>What is the biggest challenge for you as a researcher working on the report?</strong></div> <div>&quot;The IPCC collects and reports about the state of knowledge in science, technical and socio-economic assessments on climate change. Everything we write in the report is not new scientific discoveries. The main aim is to bring this knowledge to policymakers and the general public in a comprehensive, clear and accessible way. So the main challenge for us as scientific contributors is the writing. How do you communicate in a clear and unbiased way, what information to include or to exclude, how do we coordinate across chapters so there is consistent and no overlapping messages, etc.&quot; </div> <div><br /></div> <div><strong>What are the most important conclusions you can draw from your work, on a purely personal level?</strong></div> <div>&quot;The main thing I learned is the self-reflective part that I mentioned above regarding what sets this report apart from the previous reports. In a way we are asking on behalf of the public, How has science changed in this report compared to the last, how things have changed, are the challenges we face today different from the challenges we faced 4 years ago? Unfortunately IPCC mainly addresses the question of “what do we know today” rather than the question of “what has changed compared to the last assessment.” This is understandable. To answer the latter question comprehensively, it requires greater efforts conducting rigorous studies and IPCC is not set up to do that. Nevertheless it is a question I ask myself frequently while writing for the report, and I am sure that you will see a lot of discussions in the blog posts, tweets, and news columns on this later question a lot. One should be careful and take these discussions with a grain of salt though since most of them are produced quickly to provide discussion points in the news media and for the public discussion. Therefore they are good food for thoughts but one must understand that IPCC does not formally analyze such a question&quot;, says Sonia Yeh.</div> <div><br /></div> <div><strong>When it comes to the most important </strong>measures to reduce the climate impact of the transport sector, Sonia Yeh recommends the seminar, <a href="/en/areas-of-advance/energy/calendar/Pages/IPCC-WG3-Where-are-we-in-the-transitions.aspx">IPCC Sixth Assessment Working Group III report on Climate Mitigation: Where are we in the transitions?</a> It´s a public online seminar and several of the authors of the report will participate.</div> <div><br /></div> <div>“The important thing to know is that there is no silver bullet. Reducing CO2 emissions from the transport sector cannot rely on a single technology, one behavioral change or a single policy measure. Exactly how much a role different measures can contribute will depend on the region, time frame, the commitments of the governments and individual actions. The chairman of the IPCC says that IPCC is policy relevant, but not policy descriptive. IPCC does not tell policymakers or the citizens what they should do, but what they could do to reduce greenhouse gas emissions, and the impacts of different actions in terms of potential for emissions reductions”, says Sonia Yeh.</div> <div><br /></div> <div><strong>When do you think the energy will be fossil free for all transports?</strong></div> <div>“My personal reflection is that the transport energy will not be fossil free without strong policy measures. Meaning, policymakers will need to take actions to introduce policies such as carbon tax or carbon caps, incentives, standards and regulations, investments in low-carbon technology and transport infrastructure that supports zero-carbon fuels and vehicles, charging infrastructure for electric buses, cars, trucks, ferries, etc. So there is a lot to be done. But it is like “The Little Engine That Could”, we can do it! And I believe that we have the momentum. It is just a matter of how fast we want to do this”, says Sonia and highlights an <span style="background-color:initial">exampl</span><span style="background-color:initial">e</span><span style="background-color:initial"> of how fast things have changed in the last few years:<br />&quot;A few years back, most people think the only viable ways to decarbonize long-haul trucks are biofuels and hydrogen. But as the price of batteries falling faster than expected, electrifying long-haul trucks are becoming real and attractive possibilities. The only hinder is the build-up of the charging infrastructure, which of course is an intensive research area that we at our group are also working actively with many European partners. Many excellent research groups at Chalmers are also studying this from many angles including materials, batteries to system level integration like the grid impacts in Sweden and in Europe”.</span></div> <div><br /><strong>Related:<br /></strong><a href="https://www.ipcc.ch/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />IPCC, <span style="background-color:initial">The Intergovernmental Panel on Climate Change </span></a></div> <div><a href="/en/Staff/edit/Pages/sonia-yeh.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Sonia Yeh, Chalmers University of Technology</a><br /><a href="/en/departments/see/news/Pages/IPCC-reports-spread-knowledge-effectively.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />IPCC reports spread knowledge effectively​</a><br /></div> <div><span></span><a href="/en/areas-of-advance/energy/calendar/Pages/IPCC-WG3-Where-are-we-in-the-transitions.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />IPCC Webinar – Where are we in the transitions?</a><br /><br />Text: Ann-Christine Nordin</div> ​​Sun, 03 Apr 2022 00:00:00 +0200https://www.chalmers.se/en/news/Pages/New-collaboration-will-accelerate-Sweden's-green-transition.aspxhttps://www.chalmers.se/en/news/Pages/New-collaboration-will-accelerate-Sweden's-green-transition.aspxCollaboration will accelerate Sweden's green transition<p><b>​Sweden will become a world leader in battery research and electrification of transport. A new collaboration between Chalmers, Lund University and Uppsala University will contribute with more research, more engineers and continuous skills development in battery technology and power electronics.</b></p><div>​The transport sector worldwide is currently switching to fossil-free operation, and electrification is the dominant strategy. This has led to an increasing demand for research and expertise in battery development.</div> <div> </div> <div>The Swedish transport sector is in the middle of this green transformation, with the goal that the vehicle fleet will be completely fossil-free by 2045, with carbon dioxide emissions reduced by 70 percent by 2030. For industry to take a leading role in the transition to an electrified society, new knowledge and skills are needed – applied research, training of engineers and further training for current professionals.</div> <h2 class="chalmersElement-H2">Collaboration for new knowledge and skills supply</h2> <div>Today, Chalmers and the universities of Lund and Uppsala carry out world-leading research and education focused on sustainable mobility.

A study from Chalmers shows that access to the right equipment can be crucial for successful year-round cycling, and that it´s difficult to find suitable products when the bike is a vehicle rather than a sports tool.</b></p><div>​The Transport Area of Advance has funded a group of “Covid projects”, where researchers have studied how various parts of the transport system have been affected by the pandemic (see list at the bottom).</div> <div> </div> <div>One of the projects – <em>Everyday cycling in unusual times</em> – is an interview study with twelve participants in Gothenburg, who had changed their daily mode of transport to cycling to avoid public transport. Chalmers researchers Helena Strömberg and Pontus Wallgren, at the Divison of Design &amp; Human Factors, saw the opportunity to map these &quot;new&quot; year-round cyclists' overall experiences of using their bikes for both work commuting and other transports.</div> <div> </div> <div>The participants' stories entail many ideas for how different actors can contribute to climate change mitigation by making cycling more attractive in various ways – after the pandemic as well. One theme that stands out, and which so far has not received much attention, is difficulties in finding suitable products that are needed for the bicycle to function as an everyday vehicle. For example, clothes to stay dry and warm (but not too warm), trolleys or watertight bags for all the necessities that must be transported, and safety gear such as helmets and winter tires.<img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_bilder-utan-fast-format/Helena%20Strömberg%20porträtt.jpg" class="chalmersPosition-FloatRight" alt="Photo of Helena Strömberg" style="margin:5px" /><br /></div> <div> </div> <div>“The study shows that equipment is very important for successful year-round cycling, and this factor has previously been rarely discussed”, says Helena Strömberg. “The participants managed to overcome several different types of barriers by finding the right equipment. But it was an unnecessarily difficult and time-consuming process for them, and we believe that there is a lot to work with in this area to reduce barriers to cycling.”</div> <h2 class="chalmersElement-H2">Reluctantly dressed in neon colours and lycra</h2> <div>All the participants in the study had gone through a process of buying, trying and rejecting a lot of different equipment in order to end up with something that was compatible with their needs. They had struggled to find gear that was suitable for everyday cycling – most products were adapted for sport biking. And this was both a functional and an aesthetic problem.</div> <div> </div> <div>The participants didn’t want to look like “die-hard” or “sports” cyclists, and didn’t want cycling to be part of their identity. They wanted to find equipment and clothes that look normal, and that are functional for ordinary people who just get around by bike in all weathers. But in many cases they had had to accept the neon and lycra aesthetics, because that was what was available, and it was difficult enough to find products with the right functionality.<img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_bilder-utan-fast-format/Pontus%20Wallgren%20porträtt.jpg" class="chalmersPosition-FloatRight" alt="Photo of Pontus Wallgren" style="margin:5px" /><br /><br /></div> “Here we see a great opportunity for industry to develop clothing and other equipment that support cycling equally well as the speciality gear, but with a more varied and inclusive aesthetic”, says Pontus Wallgren. <div> </div> <div>But just finding out what products are available and where to find them was a hurdle for the participants. They searched with the help of informal networks, such as colleagues they met at the bike rack at work. The ferry across the river in Gothenburg proved to be a good help for those who commuted that way. There they got the opportunity to check out which equipment other cyclists had, and also to chat to them for tips and advice.</div> <h2 class="chalmersElement-H2">Better opportunities to try equipment out can make a difference</h2> <div>The researchers therefore believe that increasing the trialability and overview of products for everyday biking is a great opportunity for the bicycle industry, as well as for the public sector. For example, companies could offer a hire and buy scheme, and also offer better sales processes with tailored recommendations based on the particular cyclist's needs. The public sector could make contributions such as libraries for gear, and arenas where inexperienced bike commuters could learn about everything from equipment to the best route for them.<br /></div> <img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/350x305/Vardagscykling_sidbild_350x305px.jpg" class="chalmersPosition-FloatRight" alt="Photo of a cyclist" style="margin:5px" /><br />“Cycling all year round for all purposes in a Nordic climate is quite a skill to learn”, says Helena Strömberg. “All the participants in the study described a learning process, where they actively sought out various solutions to make cycling work in their daily life.” <div> </div> <div>The challenges for cyclists are similar in many Swedish cities. However, Gothenburg is also a very hilly city, and most of the participants had found out that a traditional bike was not compatible with the requirements of everyday cycling. They had bought a new bicycle as part of the process when they discovered their own needs – either an e-bike or a light, sporty bike with multiple gears.</div> <div> </div> <div>“In high-cycling countries such as Denmark and the Netherlands, it is often said that the only thing you need is a standard bike with an upright riding position”, says Pontus Wallgren. “But many people have a rather flat biking route there, and this is an example of the importance of finding solutions for local and individual barriers to cycling as well.”</div> <h2 class="chalmersElement-H2">Easier and more fun than expected despite the challenges</h2> <div>After all, the participants in the study had expected that it would be even more difficult to become a year-round cyclist than it actually turned out to be. And their stories contain many positive effects of biking.</div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/350x305/Vardagscykling_sidbild2_350x305px.jpg" class="chalmersPosition-FloatRight" alt="Photo of a cyclist" style="margin:5px" /><br /></div> <div>“One thing that really stands out in our results is the participants' experiences of joy, freedom and empowerment when cycling”, says Pontus Wallgren. “They had been cycling for about a year when they were interviewed, and almost all of them said they intended to continue after the pandemic as well.”</div> <div> </div> <div>But the study was specifically about people who had managed to maintain their cycling, and thus had overcome the various hurdles they had faced. They also told about colleagues who had tried to change their mode of transport to biking during the pandemic, but had given up because it was too hard.</div> <div> </div> <div>It could be small things that together made the cons outweigh the pros. Poor support for bike commuting at the workplace or home was one of them. For example, one got tired of crossing a giant car parking every day to get to a small bicycle parking where it wasn´t even possible to lock the bike to something – or of pushing wet outerwear into a locker, and then putting on the still wet clothes at the end of the working day.</div> <div> </div> <div>“Our results, as well as previous research, show that employers and house owners can also do a lot to reduce barriers to cycling”, says Helena Strömberg. “For example, by offering secure indoor bike storage and facilities for showering, drying wet clothes and recharging batteries.”</div> <h2 class="chalmersElement-H2">Lack of priority and capacity can only be partially compensated</h2> <div>The results are also in line with previous research regarding a third important factor for how many people choose to cycle: how much priority and space that are allocated to cycling in the city. Thus it comes down to urban development and policy, but also to usage and maintenance of the already existing bike lanes.</div> <div> </div> <div>Some problematic examples from the participants' stories were dangerous road sections where aggressive motorists demonstrated their perceived right to the road, sections where there were indeed cycle lanes – but very frequent stops were required for various reasons, and cycle lanes with potholes, patchy asphalt and late snow removal.</div> <div> </div> <div>Gothenburg is one of many cities that have a long way to go to reach their cycling goals, even though the mode of transport has increased during the pandemic. And overall, the participants in the study felt that biking is not a prioritised mode of transport in Gothenburg. “I almost always feel that the cars are at advantage when you go out, so I cannot think of it as a cycling city”, was one of the statements.</div> <div> </div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Transport/_puffbilder/Vardagscykling_350x220px.jpg" class="chalmersPosition-FloatRight" alt="Photo of a bicycle bell" style="margin:5px" />The consequences of this were also something they tried to compensate for with equipment. Lots of reflectors. Shock absorbers for bumpy bike lanes. And then the perfect bicycle bell, with just the right loudness, so that pedestrians on the bike lanes will hear it but not get scared or angry. It has named the scientific paper about the results of the study that was recently published: <a href="https://www.sciencedirect.com/science/article/pii/S0264275122000130" target="_blank"><em>Finding that elusive bell and other issues - experiences from starting to cycle during a pandemic.</em></a></div> <div> </div> <div>But of course there are limits to what biking gear can achieve.</div> <div> </div> <div>“Although our study indicates that equipment is a factor which needs more attention, that doesn´t mean that urban development and policy become less important”, says Pontus Wallgren. “If more people are to choose the bike for daily transport, everyday cycling absolutely needs to be prioritised in cities. That is necessary for the bike routes to be safe and efficient, but also for them to be nice environments where people enjoy cycling. All of this contributes to increasing the relative advantage of cycling over other modes of transport.”</div> <div> </div> <div> </div> <div><strong>Text:</strong> Johanna Wilde</div> <div><strong>Photo:</strong> Chalmers; Helena Strömberg and Pontus Wallgren.

Today Sweden is one of the world's most important producers of products from forest raw materials. The Wallenberg Wood Science Center now receives an additional SEK 380 million for wood research with the goal of creating new material and making the processes more sustainable and energy efficient.​</b></p>​<img src="/SiteCollectionImages/Institutioner/KB/Kemiteknik/Hans%20Theliander.jpg" alt="Hans Theliander" class="chalmersPosition-FloatRight" style="margin:5px" /><span style="background-color:initial">“The grant is a fantastic thing. We have been working with the center for almost 15 years. This means that you get an additional number of years to work with these things and expand the portfolio”, says Hans Theliander, professor of Forest Products and Chemical Engineering at Chalmers, and one of the researchers at Chalmers who has been with the Wallenberg Wood Science Center since the start in 2009.<br /><br /></span><div><strong>In his head</strong> he has a sequence for how the wood material of the forest can be used better. Think about reusing each carbon molecule 40 to 50 times before turning it into carbon dioxide. In the future, the forest industry will be far more than planks and paper.</div> <div>“In a first step, different sawn products can be manufactured and used for different purposes for several years. It can be, for example, in buildings or furniture. Then you can use the wood material in these products to produce pulp fibers, for example you can use it to make paper packaging or writing materials - when you have circulated the fiber material a number of times and the quality of the fibers is no longer as good, you could pick out nanocomponents and make different materials of nanocellulose which in many cases can replace today's plastic materials, circulate these a number of times to then extract cellulose polymers and make various textile materials, for example viscose”.<br /><br /></div> <div><strong>“I'm not done with that,</strong> says Hans Theliander, after this you can pick out the sugar molecules that are in the textile cellulose-based materials, and ferment to ethanol, a raw material for several different chemicals, not least fuel. I can take several other examples. We must start thinking in that way to make the most of the forest in the future. But then it is important to adapt the processes and material types. Future researchers have something to do here”, says Hans Theliander.</div> <div>Already today, the sawmills and pulp mills, has a good start to a sequential order In the sawmills, which are the important thing, it is sawn up to become planks. The residual streams from sawmills in form of sawmill chips together with thinning wood from manage of the forest, can go to the pulp mills. Add to this the extensive paper recycling, and we already have the first steps. But it is of course important to expand this. The Wallenberg Wood Science Center was started in 2009. The focus is on basic research that aims to develop knowledge as a basis for a new generation of innovative materials from trees.<br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/Bio/Profilbilder/Lisbeth_Olsson_2017.jpg" alt="Lisbeth Olsson" class="chalmersPosition-FloatLeft" style="margin:5px" /><strong>“Sometime in 2008</strong>, the Wallenberg Foundation held a large workshop with researchers from several subject areas on forest renewal. After that, an announcement was made in the area addressed to the universities. The result was a center between KTH and Chalmers University of Technology. Later, Linköping University would join. It was a ten-year venture. This is how the Wallenberg Wood Science Center was started”, says Lisbeth Olsson, professor of Industrial Biotechnology, who together with Hans Theliander and Paul Gatenholm, professor of Biopolymer Technology, is the initiator of the center at Chalmers.</div> <div><br /></div> <div><strong>“The philosophy </strong>at Wallenberg Wood Science Center is to develop milder process methods so that you can retain more of the structure of lignin and hemicellulose, based on building new materials where the inherent properties of the wood are utilized. The goal is to make the entire manufacturing process more energy efficient. An example of this is drainage. When to get the fiber out - it is a solid material you should have in the end. That process is enormously energy-intensive, this is what Hans Theliander works with”, says Lisbeth Ohlsson.</div> <div><br /></div> <div>Hans Theliander's track record as a researcher and innovator in the sulphate factory's recycling processes is long. In recent years, he has worked with filtration and extraction of lignin. The process - LignoBoost - is today commercialized and is in operation at two pulp mills in the world. It has the potential to be a central technology in the pulp mills of the future. Hans has also been active in pulp technology research with significant contributions concerning, among other things, heat, and mass transport during cooking and in biorefinery-related studies where mathematical modeling has been central.</div> <div>Knowledge from different areas is needed to ultimately be able to produce exciting new materials from the forest raw material, here several different specializations in materials and process technology are important. When it comes to the more &quot;chemical&quot; aspects, the whole spectrum is needed from basic chemistry, via applied chemistry to chemical engineering.<br /><br /></div> <div><strong>“My research area</strong> is about the processes needed to produce different types of materials from wood raw material. It may not be quite as “sexy” as the material itself but is of course one of the prerequisites for being able to produce different products from wood material. 20 years ago, the balance was good between chemistry, applied chemistry and chemistry / process technology. At present, there is a great imbalance”, says Hans Theliander.</div> <div>“Today, it is primarily material technology that has increased. While Chemical engineering has decreased, which is a problem”, says Hans Theliander, not only at Chalmers, but also internationally and this is a problem since engineers with that competence are needed.</div> <div>“It has been a big loss in the field of chemical engineering or process engineering as it can also be called. 20 years ago, Chalmers really had competence and good momentum in that business. But since then, several professors have retired without new recruitment”, says Hans Theliander.<br /><br /></div> <div><strong>The challenge </strong>has also been observed in the industry, which has been involved in initiating a new bio innovation program called &quot;Resource-smart industrial processes&quot;. The goal is to strengthen process / chemical engineering in Sweden. The program is the reason why Hans Theliander still works 40 percent.</div> <div>“The idea is now that Merima Hasani, researcher and associate professor in the field of Forest Industrial Chemical Engineering will take over after me. It is a national program at Chalmers with eleven doctoral students and postdocs and funded by Vinnova, the industry and academy”.<br /><br /></div> <div><strong>What does the development of process technology mean for the forest industry?</strong></div> <div>“This is about a lot. Historically, the energy has been quite cheap, which has meant that when these processes was developed the smartest and most energy efficient process solutions was not used. Some improvements have been done during the years but with improved knowledge in chemical engineering and process engineering, it is possible to optimize the processes much further and make them more energy efficient and utilize the forest material better: in the end get a better material yield. If you look at a sulphate pulp factory today - you burn half - and half become pulp fibers. It is a poor material yield. You must increase it. Which has been one of my mantras for the last 15-20 years”, says Hans.</div> <div>“People are starting to open their eyes to this, after all, wood is the most expensive part when producing pulp. You want as much out of it as possible”, he says.</div> <div>Hans Theliander's research group has worked with several proposals on how, for example, you can also use branches and tops in a smarter way. Today, fine pulpwood is used as a starting material to make viscose.</div> <div>“You can do it in another way. When you make viscose you need polymers, not a lot of fine fibers, it is enough that the polymer is okay - you can take it from branches and tops. These are the thoughts you must have in the future to make the biomaterial last”.</div> <div><br /></div> <div><strong><img src="/en/areas-of-advance/energy/PublishingImages/Making%20science%20useful/HansT_220x180px.jpg" alt="Hans Theliander" class="chalmersPosition-FloatRight" style="margin:5px" />How do you make the processes more sustainable and energy efficient?</strong></div> <div>“ I usually put it like this. We have a unique medium and that is water, which is also a good and environmentally friendly chemical. We should continue to use that. There are two problems with water, I usually jokingly say that one is 4.18 (kJ / kg K) - ie the heat capacity - that is, how much energy you need to use per degree and kilo of water.</div> <div>The second is 2300 (kJ / kg) - it is so much energy you need to evaporate a kilo of water. It is a high heat of vaporization value. An example is: When we digest the wood, the pulp fibers are suspended in the cooking liquid. We wash the pulp fiber with water and the more water we use, the greater the energy demand are later in the process. Here it is important to make the washing of the pulp fiber more efficient, use as little water as possible, to minimize the heat demand in subsequent evaporation steps”.</div> <div><br /></div> <div><strong>Is water in short supply here?</strong></div> <div>“Well, it is probably not the lack of water, but it is costly energy wise to remove the water from wet products. This takes huge amounts of energy. Just to give proportion - a partial step in the pulping process is one evaporates and concentrates the black liquor. Every second in Sweden, more than one cubic meter of water is boiled away. Enormous amounts. It is done in a smart way today, but here there is so much more to do”.</div> <div><br /></div> <div><strong>Will the society demand less forest if one succeeds in making all these efficiencies?</strong></div> <div>“You can put it in that way, but you can also say that you need to get more out of the same amount of forest. We are about to replace petroleum-based products and given that we use enormous amounts of petroleum-based products – then our needs of other raw materials, and wood will be one of the most important, is enormous. To make the forest last than we really have to be efficient.</div> <div>“What´s interesting is that not many people today know that 100 years ago it was realized that we needed to plant trees. Various laws were enacted on how forests where to be managed. That is why we have so much forest raw material today (about twice as much compared to hundred years ago). Had they not done so – Halland, south of Sweden, would probably have looked like certain parts of England. Green. With a lot of heathlands”, says Hans Theliander.</div> <div><br /></div> <div><strong>How the forest should be used best is discussed extensively by the various actors in society, what opportunities do you see in the future?</strong></div> <div>“Everything is interconnected and complex. There is a lot of politics in the whole thing. I really hope you get the right side of the discussion about the forest. In general, one can probably say that there are very well-managed forests in Sweden – and somehow, we should be able to use it in a sustainable way, but not over-utilize anything. With smarter process technology, we can help you get a higher efficiency of what you pick out of the forest. You then get more per ton of set-aside forest”.</div> <div>“It is an important message about why you should refine process technology. Personally, I do not think it is effective when you burn the wood directly, but instead we will manufacture different materials and chemicals. That we then, after several re-cycles, use it as an energy source must be OK”.</div> <div>“Another important thing – is that we should be able to reuse and circulate materials in a good way. Here, the forest industry has been at the forefront when it comes to collect different paper/board products and how to use the fibers several times. It is a good start, but we have to become even better and also expand it to other fields”, Hans Theliander concludes.</div> <div><br /></div> <div>Text: Ann-Christine Nordin</div> <div><br /></div> <div><strong>Read more:</strong><br /><br /><div><span style="background-color:initial"><a href="https://wwsc.se/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Wallenberg Wood Science Center</a><br /></span></div> <div><span style="background-color:initial"><font color="#1166aa"><span style="font-weight:700"><a href="https://treesearch.se/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Treesearch</a></span></font></span></div> <div><span style="background-color:initial"><font color="#1166aa"><span style="font-weight:700"><a href="https://treesearch.se/"></a></span></font><a href="/sv/Personal/Sidor/lisbeth-olsson.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Lisbeth Olsson</a><br /><a href="/sv/personal/Sidor/paul-gatenholm.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Paul Gatenholm</a></span></div></div> <div><br /></div> ​Fri, 18 Feb 2022 00:00:00 +0100https://www.chalmers.se/en/departments/tme/news/Pages/Scaling-up-battery-production-drive-down-carbon-emissions-significantly.aspxhttps://www.chalmers.se/en/departments/tme/news/Pages/Scaling-up-battery-production-drive-down-carbon-emissions-significantly.aspxScaling up battery production drive down carbon emissions significantly<p><b>​A common criticism of electric vehicle production is the high carbon emissions from battery production. But new research from Chalmers University of Technology in Sweden shows how scaling up production through enormous 'gigafactories' can cut the environmental impact significantly, compared to small-scale industrial production. And when the energy used to power the factories comes from green sources, the emissions can be reduced to roughly one quarter compared to results presented a few years back.</b></p><div>​The largest environmental impacts in electric vehicle manufacture usually result from the production of batteries. Over the last decade substantial research has been dedicated to analysing battery production processes to identify the steps with the highest impacts. But earlier data for such analysis has usually been derived from small-scale production facilities, or even pilot projects. </div> <div> </div> <div><span><span><span><span><span><img src="/sv/institutioner/tme/PublishingImages/Porträttbilder/mudit_chordia_170x220.jpg" class="chalmersPosition-FloatRight" alt="Mudit Chordia" style="margin:15px;width:150px;height:194px" /></span></span></span></span></span>&quot;Today, however, global battery production capacity is scaling up massively, with gigawatt facilities being commissioned and constructed – and there is little research or data that analyses how this will affect emissions. A lot of research is still published that relies on older data sources stemming mostly from small-scale battery production, thereby skewing the understanding of the environmental impacts,&quot; explains Mudit Chordia, doctoral student at the Department of Technology Management and Economics at Chalmers University of Technology, and lead author of the new study.</div> <div> </div> <div>To rectify this, the researchers used a life cycle assessment to remodel a commonly cited study relating to small scale production and combined it with updated data more representative of the most modern and state-of-the-art upcoming production facilities.</div> <div> </div> <div>&quot;Our results revealed how upscaling battery production from megawatt to the gigawatt level yields significant reductions in energy usage per kilowatt hour of battery-storage capacity produced – up to 58%. The efficiency gains of large-scale production are highly significant,&quot; continues Mudit Chordia.</div> <div> </div> <div>When adjusting for different scenarios relating to the energy supply for such factories, even in the most carbon-intensive case (based on South Korea) the researchers observe an emissions reduction of nearly 45%. In addition, if the energy is supplied from low carbon-intensity sources, the emissions reduce by <em>a further</em> 55%. If regions with low carbon electricity supplies – such as northern Sweden, where construction of Europe’s largest battery factory is currently underway – are selected for the launch of battery production at giga-scale, the potential is very good for producing batteries with lowest possible environmental footprint. </div> <h3 class="chalmersElement-H3">Access to data a challenge </h3> <div>Another important observation from the study is that with large-scale production, a greater proportion of the impacts shift further up the supply chain, to the raw material extraction and processing phases. A challenge to the researchers’ work was getting access to the relevant data to model the processes and accurately analyse the impacts. </div> <div> </div> <div><span><img src="/sv/institutioner/tme/PublishingImages/Porträttbilder/AndersNordelof_170x220px.jpg" class="chalmersPosition-FloatRight" alt="Anders Nordelöf" style="margin:15px 5px;width:150px;height:194px" /></span>&quot;In the course of our work, we found that life cycle assessment datasets often used for some of the battery raw materials, lack the coverage and precision necessary for modelling the high grade of material quality required in battery production. The supply chains for manufacturing are usually considered trade secrets, making it very challenging to collect data and to conduct a full analysis representative for all types of actors,&quot; explains Anders Nordelöf, researcher at Chalmers University of Technology and co-author of the study. </div> <div> </div> <div>&quot;For further reductions of the environmental impacts from battery production, the manufacturers and wider battery industry need to make a focused effort on procuring raw materials from low-carbon intensity mineral extraction. But in such a competitive industry, this will remain a challenge for many actors.&quot; </div> <div> <br /><div><br /></div> <div><em>Text: Daniel Karlsson, Joshua Worth</em><br /><em>Foto: Chalmers samt via Northvolt</em></div> <br /></div> <h3 class="chalmersElement-H3">More about the study: </h3> <div>The scientific study, <a href="https://doi.org/10.1007/s11367-021-01976-0" target="_blank">Environmental life cycle implications of upscaling lithium-ion battery production</a> by Chalmers University of Technology researchers Mudit Chordia and Anders Nordelöf, together with Linda Ager-Wick Ellingsen, Norsk institutt for naturforskning, was published in The International Journal of Life Cycle Assessment, 2021.</div> <div> </div> <h3 class="chalmersElement-H3">Contact information: </h3> <div><strong>Mudit Chordia</strong></div> <div>Doctoral student, Technology Management and Economics, Chalmers University of Technology</div> <div><a href="mailto:mudit@chalmers.se">mudit@chalmers.se</a></div> <div>+46 31 772 6313<br /><br /></div> <div><strong>Anders Nordelöf</strong></div> <strong> </strong><div>Researcher, Technology Management and Economics, Chalmers University of Technology</div> <div><a href="mailto:anders.nordelof@chalmers.se">anders.nordelof@chalmers.se </a></div> <div>+46 31 772 8611<br /><br /></div>Tue, 08 Feb 2022 12:00:00 +0100https://www.chalmers.se/en/departments/m2/news/Pages/TechForH2---for-a-sustainable-hydrogen-economy-of-tomorrow.aspxhttps://www.chalmers.se/en/departments/m2/news/Pages/TechForH2---for-a-sustainable-hydrogen-economy-of-tomorrow.aspxFor a sustainable hydrogen economy of tomorrow<p><b>​“Getting a node for vehicle research and hydrogen with its main focus in the western part of Sweden is fantastic. And it’s of course also great that we’ll now get a center that focuses on collaboration between different modes of transport,” says Tomas Grönstedt, coordinator of the competence center TechforH2, which now receives almost SEK 54 million from the Swedish Energy Agency in order to develop new technology in hydrogen propulsion as a step towards conversion to fossil freedom.</b></p>​<span style="background-color:initial">It was just before Christmas that the Swedish Energy Agency announced their large investments in centers that research sustainable energy systems. A total of SEK 600 million is to be distributed in grants to eleven different competence centers, of which more than half are based at Chalmers - as the main applicant in four cases and co-applicants in two.

The focus so far has been mainly on the importance of electrification, especially in the automotive industry. But for heavier vehicles and trucks, which account for 30% of the transport system's total carbon dioxide emissions, electrification is somewhat trickier as it would entail a very large number of batteries to drive such heavy vehicles, which in turn comes with consequences in terms of weight, space and costs.</div> <div><br /></div> <div>Subsequently, there has been a need for research that develops new technical solutions that reduce greenhouse gases and harmful emissions, that aren’t dependent on fossil energy sources, and that, at the same time, answers to the needs of the truck industry and other industries that depend on heavy transport, such as aviation.</div> <div><br /></div> <div>With the Swedish Energy Agency's major investment in TechForH2, the hope is now to be able to contribute to knowledge building and education in the area, accelerate the introduction of new technology and thereby contribute to the transition to fossil freedom. More specifically, TechForH2's focus areas will include composites and lightweight structures for vehicle-integrated hydrogen storage and the manufacture and post treatment of metallic materials for, among other things, hydrogen use and sensors. Additionally, the center will further research on fuel cells and vehicle integration and technology/instruments and innovations in a future hydrogen society.</div> <h2 class="chalmersElement-H2">New recruitments on the way</h2> <div>TechForH2 is coordinated and led by Chalmers, which owns the center with RISE being an academic partner.
