Everything we produce today with fossil raw materials can be made from forest materials, which can play an important role in climate change. But we need more environmentally friendly and energy-efficient processes and to use our natural resources in a more sustainable way.</b></p>​<img src="/SiteCollectionImages/Institutioner/KB/Kemi_och_Biokemi/Organisk_kemi/k99meme-Merima-Hasani.jpg" alt="Merima Hasani" class="chalmersPosition-FloatLeft" style="margin:5px" /><span style="background-color:initial"><strong>Merima Hasani is a researcher</strong> and associate professor within the field Forest Industrial Chemical Engineering. The forest has always been central for her, both for recreation and as a resource. Now she has become project manager for the newly started Bio innovation Program – Resource-Smart Processes – a national industrial graduate school. <br />The aim for this project is to increase knowledge of chemical and process technology, to make the processes more energy efficient and to make better use of the forest material.<br /><br /></span><div>“It is about using the forest more resource efficiently. We will reuse the structures we take from the forest today and convert into paper or textiles into clothes as building blocks for other materials, so that they spin around for many years. My goal as a researcher is that the resources should be used in a sustainable way. Sometimes you come up with solutions to take molecules out of the forest and then burn them - it is a waste of what nature has built. We can do that since the price for what we use haven´t been set right”, says Merima.</div> <div><br /></div> <div><strong>The core of what today constitutes</strong> Merima Hasani's great interest as a researcher at Chalmers was aroused at a young age at home in Varberg.</div> <div>“Even as a child, I wanted to understand how things are built on a molecular level. I grew up with a mother who was a chemistry and biology teacher, and I was fascinated by molecules. It is somehow the core of everything”.</div> <div>During high school, her interest in technology was also aroused.</div> <div>“I came to the conclusion that if you should apply chemistry and create new molecules, you should combine it with something more, so I applied for an education that allowed me to connect it with something that was applicable”.</div> <div><br /></div> <div>“To be honest, when I look back to when I applied to Chalmers in 1999, I did not really know what chemical engineering was - but it allowed me to apply chemistry on a larger scale. That's how it started”.</div> <div>Merima Hasani started her studies at Chalmers in the autumn of 1999. In October 2010, she defended her doctoral theses in Organic Chemistry with the title &quot;Chemical modification of cellulose - new possibilities of some classical routes&quot;. <br /><br /><strong>Merima had studied the possibility</strong> to give cellulose fibers new functionality and thereby create conditions for new or improved product properties. For that, she was awarded the 2011 Competence Development Award. In the same year, the trip went to Austria and the University of Natural Resources and Life Sciences, BOKU, in Vienna, which has a leading research group in this field. <br />In 2016 she was awarded Future research leader by Formas. With that, she deepened her knowledge and the work with new concepts for dissolution and transformation of cellulose as an alternative and more environmentally friendly way to, among other things, create textile fibers.</div> <div>Since 2014, Merima has been connected to the Wallenberg Wood Science Center - a collaboration between The Royal Institute of Technology (KTH), Chalmers University of Technology, Linköping University, and the forest industry. The center has built up deep knowledge of how the tree's constituent parts – cellulose, hemicellulose and lignin – can be separated and used in new materials.<br /><br /></div> <div><strong>“The Resource-smart Processes program </strong>and the Wallenberg Wood Science Center complement each other. The industry has realized the importance of investing in both”.</div> <div> “Wallenberg Wood Science Center is very focused on fundamental research towards the development of new materials based on forest biomass. In Resource-Smart processes, we focus on building the knowledge needed to be able to produce these materials”, says Merima Hasani.<br /><br /></div> <div>Process engineering knowledge in Sweden regarding separation and valorization of forest biomass is world-leading, but there has been a major loss in the area. Twenty years ago, Chalmers really had the skills and good momentum in that business. But since then, several professors have retired without new recruitment. This was noticed by Hans Theliander, professor of Forest Industrial Chemical Engineering at Chalmers, Daniel Söderberg from KTH and Torgny Persson, Forest Industries. The three are the key people, together with the industry behind &quot;Resource-smart processes&quot;. <br />In January this year, the business graduate school kicked off with the goal of strengthening process engineering research and education in Sweden. The program has eleven doctoral students and postdocs and is funded by Bio Innovation, industry, and academia.<br /><br /></div> <div><strong>Now Merima Hasani has taken over as coordinator</strong></div> <div>“Hans Theliander and I have worked together for a long time, he is one of the brains behind the program and has made a big impression”, she says.</div> <div>All projects in &quot;Resource-smart Processes&quot; are led by research leaders within the academy, while the research issues are developed together with industry. Several of the projects involve several different industry partners.</div> <div>“It is fun for us and the doctoral students to work close to the industry and feel the commitment that exists, and that their research can contribute to benefit the society. Within the program, we put competition aside to build knowledge that everyone benefits from - to move forward faster. Then we must agree on the major research issues”, says Merima.<br /><br /></div> <div><strong>So, what hasn´t been that smart previously?</strong></div> <div>“It is above all the processes linked to renewable resources, the forest biomass. They should help us manage the wood raw material and the energy in the best possible way. That’s why it is important to think about, streamline and reuse”.</div> <div>With chemical and process technical knowledge, it is possible to optimize and redesign the processes, make them more energy efficient and utilize the forest material better, get a better material production yard simply.</div> <div> <br /><strong>This is about many things.</strong></div> <div>“In other words, the energy issue has always been an important part of the strategic thinking around process development. It is always included in our discussions and analyzes. Now it's more important than ever. Even the forest debate - before the Ukraine war - put everything at its peak. So again. We must be extremely careful with what we get from the forest so that every green structure, with every carbon atom is used in the best way. We must ensure that as much as possible can be reused. Resource efficiency and circularity are very important. That is the direction we must have in the future. I can´t see any other way”, says Merima Hasani.<br /><br /><div><a href="/sv/personal/Sidor/merima-hasani.aspx" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /></a><a href="https://www.bioinnovation.se/resurssmartaprocesser/">The Industrial graduate school Resource-smart Processes</a></div> <div><a href="https://wwsc.se/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Wallenberg Wood Science Center</a></div> <div><a href="/sv/personal/Sidor/merima-hasani.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Merima Hasani</a></div> <br />Text: Ann-Christine Nordin</div>Wed, 06 Jul 2022 00:00:00 +0200https://www.chalmers.se/en/departments/see/news/Pages/Pioneering-recycling-turns-mixed-waste-into-premium-plastics-with-no-climate-impact.aspxhttps://www.chalmers.se/en/departments/see/news/Pages/Pioneering-recycling-turns-mixed-waste-into-premium-plastics-with-no-climate-impact.aspxPioneering recycling turns mixed waste into premium plastics with no climate impact<p><b>​Only a fraction of the material that could be turned into new plastic is currently recycled. Researchers at Chalmers have now demonstrated how the carbon atoms in mixed waste can replace all fossil raw materials in the production of new plastic. The recycling method is inspired by the natural carbon cycle and could eliminate the climate impact of plastic materials, or even clean the air of carbon dioxide.</b></p><strong>​</strong><img src="/sv/institutioner/see/nyheter/PublishingImages/HenrikThunman_191004_091.jpg" alt="Henrik Thunman" class="chalmersPosition-FloatRight" style="margin:5px" /><span style="background-color:initial"><strong>“There are enough carbon</strong> atoms in waste to meet the needs of all global plastic production. Using these atoms, we can decouple new plastic products from the supply of virgin fossil raw materials. If the process is powered by renewable energy, we also get plastic products with more than 95% lower climate impact than those produced today, which effectively means negative emissions for the entire system,” says Henrik Thunman, Professor of Energy Technology at Chalmers University of Technology and one of the authors of the study published in the Journal of Cleaner Production. </span><div><br /><span style="background-color:initial"></span><div>To achieve circular cycles, we need to make better use of the resources already in use in society. Henrik Thunman and his research team want to focus on an important resource that often goes up in smoke today: the carbon atoms in our waste, which are currently incinerated or end up in landfills instead of being recycled. This is made possible with technologies targeting the carbon contained in plastic, paper and wood wastes, with or without food residues, to create a raw material for the production of plastics with the same variety and quality as those currently produced from fossil raw materials. </div> <div><br /></div> <div><strong>Just like nature </strong></div> <div>Current plastic recycling methods are able to replace no more than 15-20% of the fossil raw material needed to meet society’s demand for plastic. The advanced methods proposed by the researchers are based on thermochemical technologies and involve the waste being heated to 600-800 degrees Celsius. The waste then turns into a gas, which after the addition of hydrogen can replace the building blocks of plastics. Using this recycling method could decouple new plastic products from the supply of new fossil raw materials.</div> <div>The researchers behind the study are developing a thermochemical recycling method that produces a gas which then can be used as a raw material in the same factories in which plastic products are currently being made from fossil oil or gas. Different types of waste, such as old plastic products and paper cups, with or without food residues, are put into the reactors at the Chalmers Power Central.</div> <div><br /></div> <div>“The key to more extensive recycling is to look at residual waste in a whole new way: as a raw material full of useful carbon atoms. The waste then acquires value, and you can create economic structures to collect and use the material as a raw material worldwide,” says Henrik Thunman. </div> <div>The principle of the process is inspired by the natural carbon cycle. Plants are broken down into carbon dioxide when they wither, and carbon dioxide, using the sun as an energy source and photosynthesis, then creates new plants. </div> <div><span style="background-color:initial">“H</span><span style="background-color:initial">owever, our technology differs from the way it works in nature because we don’t have to take the detour via the atmosphere to circulate the carbon in the form of carbon dioxide. All the carbon atoms we need for our plastic production can be found in our waste, and can be recycled using heat and electricity,” says Henrik Thunman. </span><br /></div> <div><br /></div> <div>The researchers’ calculations show that the energy to power such processes can be taken from renewable sources such as solar, wind, hydro power or biomass​, and they will be more energy-efficient than the systems in use today. It is also possible to extract excess heat from recycling processes, which in a circular system would compensate for the heat production currently derived from waste incineration, while eliminating the carbon dioxide emissions associated with energy recovery. </div> <div><br /></div> <div><strong>Can replace fossil raw materials</strong></div> <div>The research has been carried out as part of the FUTNERC* project. The researchers have proven that the process can work in collaboration with plastics manufacturer Borealis in Stenungsund, Sweden, where they have verified the results and shown that the raw material can be used to make plastic, replacing the fossil raw materials used today. </div> <div>“Our goal is to create a circular economy for plastics. Our plastic products are key to the transformation to a sustainable society, so it’s important for us to support research like this. We already have projects that create circularity for our plastic products, but more solutions are needed.

Many new medicines have proved to be highly sensitive to strong chemicals, which creates a major production problem for the next generation of biomedicines. The lower consumption of chemicals results in a benefit to the environment, while the fact that the surfaces of the new material can also be reused through several cycles is a key property.

Competition horses develop the disease very early as a result of intensive training at a young age. As part of a large collaborative project between the Swedish University of Agricultural Sciences (SLU) and Sahlgrenska University Hospital (SU), researchers at Chalmers have been involved in developing a new method to enable early diagnosis of osteoarthritis in horses.</b></p><div>“Osteoarthritis is a chronic joint inflammation where the disease process is slow and difficult to diagnose at an early stage. But to be able to treat it, it is important to identify the early stages”, says Eva Skiöldebrand, professor of general pathology at the Swedish University of Agricultural Sciences (SLU) with a focus on osteoarthritis in horses and humans.<br /><br /></div> <div>“Together with professors Stina Ekman at SLU and Anders Lindahl at SU, our research group has developed biomarkers, or more specifically, identified new neoepitopes* that are generated when protein from articular cartilage and underlying subchondral bone (bone under articular cartilage) is broken down by inflammation, which is the hallmark of the disease. The research group has been able to verify the biomarkers in serum and synovial fluid in horses with varying degrees of osteoarthritis and studied the effect of training and the effect of circadian rhythm, which is a major research breakthrough, says Eva Skiöldebrand.<br /><br /></div> <div>The use of biomarkers allows the disease to be detected earlier and the occurrence of serious injuries to be prevented – and the effectiveness of drugs for the treatment of osteoarthritis can be evaluated.</div> <div><br /></div> <div><strong>Early diagnosis with saliva test</strong></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Health/Udda%20format/Artros_bild_450x350.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />One person who has played a large part in a related research breakthrough at the end of 2021 is Moa Lord, a former biotechnology student and now a research assistant in materials physics at Chalmers. <span style="background-color:initial">Together with the research group at SLU and SU, she has developed a new method for quantifying biomarkers in saliva in horses, under the supervision of professor Eva Skiöldebrand, Susanne Nyström, PhD in molecular biology, BMA at SU, and Magnus Karlsteen, associate professor of materials physics at Chalmers and responsible for Chalmers' initiatives in equine technology.</span></div> <div><br /></div> <div>“We wanted to develop a method that could easily fit into the daily horse keeping. Saliva sampling is a non-invasive sampling method in contrast to synovial fluid samples and blood samples, which means that you can take more samples without creating discomfort in the horse. Detection and quantification of the biomarker in saliva enables an easier way to monitor how the biomarker is affected by training and surfaces, and detection of early signs of disease”, says Moa Lord.<br /><br /></div> <div><strong>Self-developed bit for horses</strong></div> <div>To facilitate saliva sampling, Chalmers has refined the method by producing a special bit for horses.</div> <div>“When we discovered that we could use saliva to measure the biomarker, we wanted to investigate how the biomarker changes during a training session when the strain on the joint increases. That is why we at Chalmers have designed and constructed a bit with space for sampling tubes. The bit collects the saliva while riding or driving the horse. This enables us to collect samples in a simpler way and that the training session can be completed without a major interruption to take a sample”, says Moa Lord.<br /><br /></div> <div>“This bit and the ability to detect the biomarker in saliva is the basis for a completely new diagnostic method, there is no one who has done something similar before. The current test tubes in the saliva collection bit work well. But we are working for the long-term goal of implementing an electronic graphen sensor e in the bit, which can provide continuous measurement values of the biomarker and test results directly on site. This would enable the horse owner from home to consult with a veterinarian and follow the development of the disease and act by working preventively to eliminate incipient disease”, says Magnus Karlsteen.<br />​<br /></div> <div>“Considering that a large number of competition horses develop osteoarthritis, the bit is important for the preventive work. Being able to measure the biomarker in saliva means that we can measure the effect of training when the horse runs and rides on different surfaces and at different paces. Then you can tailor training programs that will not harm the joints and hopefully it can result in fewer horses developing the disease”, says Eva Skiöldebrand.<br /><br /></div> <div><strong>Continued funding of the project</strong></div> <div>Moa Lord’s project &quot;Can we use saliva to detect osteoarthritis in the horse?&quot; has been part-financed by the Health Engineering Area of Advance at Chalmers. At the beginning of 2022, The Swedish Association for the Protection of Animals granted funding to investigate the presence of pain biomarkers in the saliva of horses. “The presence of pain biomarkers in saliva can provide an enormous amount of information about the horse's pain status and we are incredibly grateful for this research money”, says Eva Skiöldebrand.<br /><br /></div> <div>“The success of this research project is fantastically gratifying and hopeful for the diagnosis and prevention of osteoarthritis in horses, but also in humans in the future”, says Martin Fagerström, Co-Director of Health Engineering Area of Advance at Chalmers.<br /><br /></div> <div><strong>Joint commitment to horse welfare</strong></div> <div>The collaboration between Eva Skiöldebrand, SLU, and Magnus Karlsteen and Moa Lord at Chalmers has, among other things, its background in a common interest in equestrian sports and a strong commitment to horse welfare. Their paths have, among other things, been crossed at the Chalmers fence, an event in connection with the World Cup competitions in horse jumping in Gothenburg, with Magnus Karlsteen as responsible.</div> <div><br /></div> <div><strong>Reinforced focus on sports technology</strong></div> <div>According to the International Horse Sports Confederation, Chalmers is world leading in equestrian technology.<br /><span style="background-color:initial"><br />From 1 August 2022, Chalmers will be the first national sports university in Sweden to become a competence centre for sports technology.

At Chalmers University of Technology, Sweden, a research team has created a unique method for further developing hydrofoils that can significantly increase the range of electric vessels and reduce the fuel consumption of fossil-powered ships by up to 80 per cent.</b></p>​<span style="background-color:initial">While the electrification of cars is well advanced, the world's passenger ferries are still powered almost exclusively by fossil fuels. The limiting factor is battery capacity, which is not enough to power ships and ferries across longer distances. But now researchers at <strong>Chalmers and the marine research facility SSPA</strong> have succeeded in developing a method that can make the shipping industry significantly greener in the future. The focus is on hydrofoils that, like wings, lift the boat’s hull above the surface of the water and allow the boat to travel with considerably less water resistance. A technology that in recent years has revolutionised sailing, by which hydrofoils make elite sailors' boats fly over the surface of the water at a very high speed. <br /></span><div>The researchers at Chalmers and SSPA now want to enable the sailboats' hydrofoil principle to be used on larger passenger ferries as well, resulting in enormous benefits for the climate. <br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Arash%20200x200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px" /><br /><span style="background-color:initial"><strong>&quot;</strong></span><span style="background-color:initial"><strong>The electrification of ferries cannot be done</strong> without drastically reducing their water resistance. This method will allow the development of new foil designs that can reduce resistance by up to 80 per cent , which in turn would significantly increase the range of a battery powered ship. In this way, we could also use electric ferries on longer distances in the future,&quot; says research leader <strong>Arash Eslamdoost</strong>, Associate Professor in Applied Hydrodynamics at Chalmers and author of the study Fluid-Structure Interaction of a Foiling Craft published in the Journal of Marine Science and Engineering.</span><br /></div> <div><br /></div> <div>Even for ships that today run on fossil fuels the climate benefit could be enormous, as similar hydrofoil technology could reduce fuel consumption by no less than 80 per cent. <br /></div> <h2 class="chalmersElement-H2">Unique measurement method arouses broad interest </h2> <div>At the centre of the research project is a unique measurement technique that the researchers have put together in order to understand in detail how hydrofoils behave in the water when, for example, the load or speed increases or the positioning of the hydrofoil changes. Using the data collected from the experiments, the team has developed and validated a method to simulate and predict with great precision how the hydrofoil would behave under a variety of conditions. The method is unique of its kind and can now be used to develop the design of hydrofoils for electric powered hydrofoil ferries.<br /></div> <div><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Laura%20200x200.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 15px" />The study was conducted in collaboration with the research facility SSPA – one of only a few of its kind in the world – where <strong>Laura Marimon Giovannetti</strong> works as a researcher and project manager. She is the lead author of the study and has herself competed at the elite level for both the British and Italian national sailing teams. Today she is a research and development adviser to Sweden's Olympic committee and the Swedish national team with her sights set on helping the team win more medals at the Olympics in 2024. Marimon Giovannetti sees many possibilities for the unique measurement method developed by the team: </div> <div><br /></div> <div><div><strong>&quot;At the Americas Cup in San Francisco Bay in 2013</strong>, it was the first time we saw a 72-foot sailing boat learning how to “fly” using hydrofoils during the competition. And since then, we've seen a huge increase in sailing boats with hydrofoils. With this new method and knowledge we are able to bring together a range of different branches of engineering – naval architecture, advanced materials and aeronautics as well as renewable energy.&quot;</div></div> <h2 class="chalmersElement-H2">Paving the way for hydrofoils on electric ferries </h2> <div>Hydrofoil technology is not in itself a novelty, but was developed as early as the 60s and 70s. Back then the focus was on getting boats to travel at as fast as possible and the hydrofoils were made of steel, a heavy material with higher maintenance costs. Today's modern hydrofoils are made of carbon fibre, a much lighter and stiffer material that can maintain its rigidity even under high loads – and can be tailored to the expected loads. Part of the research project was therefore to fully understand how a carbon fibre structure behaves underwater during different operational conditions. The research team's method developed in association with modern technology is now paving the way for the use of carbon fibre hydrofoils on larger passenger ships that can travel in a safe, controlled and climate-friendly way even at low speeds. <br /><br /></div> <div><strong>&quot;You want the foil to be as efficient as possible</strong>, which means carrying as much weight as possible at as low a speed as possible with the least resistance. Our next goal is to use this method when designing more efficient hydrofoils for ferries in the future,&quot; says Eslamdoost.</div> <div><br /></div> <div><strong>More about the scientific article </strong></div> <div>The study <a href="https://www.mdpi.com/2077-1312/10/3/372">&quot;Fluid-Structure Interaction of a Foiling Craft&quot;</a> has been published in the Journal of Marine Science and Engineering.

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. A specially designed catalyst releases the saved energy as heat while returning the molecule to its original shape, so it can then be reused in the heating system. Now, in combination with an micrometer-thin thermoelectric generator, the energy system can also generate electricity to order.</div> <div><br /></div> <div>Photo above to the right: Maria Quant and Zhihang Wang, postdocs in the Most research group, in the front a modell of the specially designed molecule <span style="background-color:initial;color:rgb(17, 102, 170);font-family:&quot;open sans&quot;, arial, sans-serif;font-size:12px">​</span><br /></div> <div><h3 class="chalmersElement-H3" style="font-family:&quot;open sans&quot;, sans-serif">Read previous press releases about the energy system Most</h3> <div><ul><li>​<a href="https://news.cision.com/chalmers/r/window-film-could-even-out-the-indoor-temperature-using-solar-energy%2cc3205508" title="Link to press release ">Window film can even out the temperature using solar energy</a></li> <li><a href="https://news.cision.com/chalmers/r/emissions-free-energy-system-saves-heat-from-the-summer-sun-for-winter%2cc3179315" title="Link to press release ">Emission-free energy system saves heat from the summer sun to the winter​</a></li></ul></div></div> <h3 class="chalmersElement-H3">More about the research and the scientific article </h3> <div><ul><li>​The study <a href="https://doi.org/10.1016/j.xcrp.2022.100789" title="Link to scientific article ">Chip-scale solar thermal electrical power generation</a> is published in Cell Reports Physical Science.

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”, says Sonia Yeh, who contributed to UN’s Intergovernmental Panel on Climate Change´s (IPCC) report, which was presented on the 4th of April.​</b></p>​<span style="background-color:initial">WG III, is the final part of the IPCC’s Sixth Assessment Report, and it focuses on climate change mitigation, assessing methods for reducing greenhouse gas emissions, and removing greenhouse gases from the atmosphere. </span><div><br /></div> <div><strong>“So the main challenge for us as scientific contributors</strong> 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.”, 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/areas-of-advance/energy/news/Pages/Invitation-apply-for-funding-for-interdisciplinary-research-ideas-within-all-energy-fields.aspxhttps://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Invitation-apply-for-funding-for-interdisciplinary-research-ideas-within-all-energy-fields.aspxInvitation – Apply for funding for interdisciplinary research ideas within all energy fields<p><b>​Call: Invitation to apply for funding from Energy Area of Advance, for interdisciplinary research ideas within all energy fields.
