The EU funded initiative is a collaboration between nine local partners and is being held to find new ways towards a fossil-free energy supply system at international level.​</b></p>​The Fossil-free Energy Districts (FED) project has been running for a year and a half, and now the digital, IoT-based marketplace is ready to be connected to campus buildings and tested in a sharp spot. The idea is that buildings that both consume and in some cases produce energy should communicate with each other to avoid energy consumption peaks that are both expensive and bad for the environment.<br /><br />– FED's marketplace is unique in several ways, partly because it connects both electricity, heat and cooling, and partly because it allows smaller players, such as a property owner who has installed solar panels on the roof, to participate in energy trading. At the same time, the system is connected to the larger external network, in our case Göteborg Energi, which provides cover when needed, says Claes Sommansson, FED Project Manager at Johanneberg Science Park.<br /><br />The FED system handles large amounts of data, both from property owners own systems and information such as weather and electricity pricing, and is updated hour by hour. But it is not the property owners themselves who have to process the information. This work is done by smart digital agents who make decisions to optimize energy efficiency in the area. The AI agents are programmed by Ericsson and based on machine learning, which means that they will get better at their job over time.<br /><br /><div>– The biggest advantage of FED is that it's a flexible system and that's something we'll need in the future when the share of energy from renewable sources, like solar and wind, grows. The uneven supply of these sources causes price fluctuations to grow, but the agents in the FED system can for example predict a cold spell and decide to start heating a house before it happens. In this way, you can buy energy at a lower price, before demand increases, but you also avoid burning fossil fuels like gas and oil, says Ericsson's Joakim Pontén, who has been in charge of the IT solution within FED.</div> <div><br />Researchers at Chalmers have done simulations and analysis to build the models that will make the energy system and the marketplace work. <a href="/en/departments/e2/news/Pages/Chalmers-is-becoming-a-unique-marketplace-for-energy.aspx">Read more about the work of the researchers.</a><br /></div> <br />The two property owners at Chalmers, Akademiska Hus and Chalmersfastigheter, are obvious partners in the project, and together they are making significant investments that will be rolled out in the autumn, including several new solar cells and a large battery for storing solar power. The entire FED system is expected to be operational at the end of the year, and the tests being carried out now are an important milestone.<br /><br />– A major challenge has been to connect the property owners' systems with Ericsson and Göteborg Energi's systems. The test week we are now completing is confirmation that our property systems linked to the parent FED marketplace are working well, says Per Löveryd, Innovation Coordinator at Akademiska Hus. <div><img class="chalmersPosition-FloatLeft" alt="Joakim Pontén and Per Löveryd" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Chalmers%20blir%20unik%20handelsplats%20för%20energi/FED-Per-Löveryd-Joakim-Ponten_500px.jpg" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><div><br /></div> <div>Joakim Pontén, Ericsson and Per Löveryd, Akademiska Hus. <br /></div> <div><br /></div> <div><strong>Facts about the project</strong></div> <div>The Fossil-free Energy Districts project, FED, is an innovative effort by the City of Gothenburg to decrease the use of energy and the dependence on fossil fuel in a built environment.

In recent years we have focused on how to best incorporate energy from renewable sources or increase the use of electric vehicles in current or future systems. How does supply and demand interact with each other? How will different policy solutions impact the system? It’s really important to look at how different components influence each other, so you don’t focus on one problem and miss other aspects, says Sonia Yeh professor at the division of Physical Resource Theory at Chalmers' department of Space, Earth and Environment. </div> <div><br /></div> <div>An energy system has typically social, technical and economic aspects, and the research is usually focused on long term models, from 10 up to a 100 years.  </div> <div><span style="background-color:initial"> </span></div> <div>– Most people have the misconception that energy models can predict the future. But that is not the case. The future is impossible to predict given all the knowable and unknowable uncertainty.

For heavy industries, such as oil refineries, or the paper and pulp industry, it is especially urgent to start moving, because investment cycles are so long. At the same time, it is important to get the investment right because you may be forced to replace boilers or facilities in advance, which means major financial costs. Thanks to long-term strategic efforts, researchers at Sweden´s Chalmers University of Technology have now paved the way for radical changes, which could be applied to new installations, as well as be implemented at thousands of existing plants around the globe.</div> <div><br /></div> <div>The solution presented involves widespread gasification of biomass. This technology itself is not new. Roughly explained, what is happening is that at high temperatures, biomass is converted into a gas. This gas can then be refined into end-products which are currently manufactured from oil and natural gas. The Chalmers researchers have shown that one possible end-product is biogas that can replace natural gas in existing gas networks.</div> <h6 class="chalmersElement-H6">The problems with tar are solved​</h6> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/tar-problem-before-and-after.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Previously, the development of gasification technology has been hampered by major problems with tar being released from the biomass, which interferes with the process in several ways. Now, the researchers from Chalmers’ division of Energy Technology have shown that they can improve the quality of the biogas through chemical processes, and the tar can also be managed in completely new ways, see images to the right.

A prototype for wireless charging of city buses is constructed by researchers at Chalmers. The first round of tests is promising.</b></p><div>​<img class="chalmersPosition-FloatRight" alt="Yujing Liu" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Prototypen%20som%20laddar%20bussen%20trådlöst/Yujing_Liu_300x388px.jpg" style="margin:5px;width:200px;height:259px" />In the laboratory at the division of Electric Power Engineering several prototypes for charging electrical vehicles are under construction and testing. <br /><br />In this project, the researchers focus primarily on charging of electric buses operated in cities as they traffic pre-determined routes with specified stops that offer good charging possibilities. Frequent charging allows for substantial reductions in battery size, which lowers the weight and cost of the bus. Alternatively, frequent charging can be used to reduce the depth of discharge, which prolongs the lifetime of the batteries.<br /><br />“The first round of tests on our 50 kW module has been completed in our laboratory and the results are promising so far”, says Yujing Liu, Professor at the department of Electrical Engineering. “The results show a transfer efficiency, from DC to DC, of about 95 percent at the desired power level, across an airgap of 20 centimetres, which is really good.” <br /><br /><strong>Charging the bus from the ground</strong><br />The wireless charging, or inductive power transfer (IPT) as the researchers call it, allows for contactless transfer of power across an air gap that extends from a charging unit in the ground, located at the bus stop, to a similar unit integrated in the vehicle frame of the electric bus. <br /><br />The charging unit in the ground contains a coil which creates a magnetic field. In turn, this magnetic field induces a voltage in a similar coil embedded in the unit placed beneath the vehicle and this induced voltage yields a current that charges the batteries in the electric bus. <br /><br /><span><img class="chalmersPosition-FloatRight" alt="Thomas Rylander" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Prototypen%20som%20laddar%20bussen%20trådlöst/Thomas_Rylander_300x388px.jpg" style="margin:5px;width:200px;height:259px" /><span style="display:inline-block"></span></span>“Essentially, this part of the system is a conventional transformer but, as opposed to a typical transformer, the primary and secondary coils are separated by a relatively large air gap. The gap yields a rather low magnetic coupling and this is compensated for by adding capacitors to the coils such that we get resonance circuits on both the primary and secondary side”, says Thomas Rylander, Professor at the department of Electrical Engineering.<br /><br />To charge the batteries in a bus would require about 200 kW, which will be made possible by connecting charging modules in parallel. <br /><br />The possibility to charge city buses at bus stops, so called opportunity charging, may reduce the size of the battery in the bus, perhaps by as much as 70 percent. About 30 seconds charging at every other bus stop will be enough to keep the batteries at a sufficient charging level – just about the time it takes for passengers to get on or off the bus.<br /><br />Thus, this charging method is different from the one used for the well-known <a href="" target="_blank">Electricity bus trafficking route 55 in Gothenburg</a>. Bus 55 is charged at the end stops using physical connectors on the roof.<br /><br /><strong>Higher efficiency and reduced battery size</strong><br />“The two major challenges that may limit the applications of inductive power transfer in electrical vehicles are the transfer efficiency and the size of the equipment”, says Yujing Liu. “However, the progress in fast-switching power electronics and high-frequency electromagnetic materials has led to new opportunities. We want to explore the benefits of using these kinds of new technology and high-quality materials for reducing losses and the size of the equipment.”<br /><br />Using high electric frequency, it is possible to reduce the magnetic energy and leakage field, which is important for applications in public places like city buses.<br /><br /><span><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/E2/Nyheter/Prototypen%20som%20laddar%20bussen%20trådlöst/powerelectronics_transformer_750px.jpg" alt="" style="margin:5px" /><span style="display:inline-block"></span></span><br /><br /><span><em>The pictures show the first prototype of power electronics (to the left) and the primary side transformer (to the right) used for inductive power transfer.

Chalmers researchers Árni Halldórsson, Holger Wallbaum, Ida Gremyr and Sofia Börjesson are receiving the award for their multidisciplinary collaboration.</b></p>​ <br />Digitalisation is contributing to far-reaching changes in almost all sectors of society, which means that we can do things in different ways and do completely new things. At the same time, we must address the question – how?<br /><br />Researchers from the departments of Technology Management and Economics, and Architecture and Civil Engineering are collaborating on the project “Energy Services: Processes for Innovation, Provision, and Use of Customer Feedback”. <br /><br />“The energy sector faces a challenge as on the one hand it needs to obtain a good return on its sales of renewable energy and from its capabilities and technology, while on the other also contributing to the customer’s energy efficiency. We are therefore looking at new ways of designing services which provide added value for customers, promoting the transition to sustainable energy consumption and guaranteeing steadyrevenue streams”, says project manager Halldórsson.<br /><br /><strong>Customers become key players</strong><br />Customers and end-users can become key players in the energy company’s ecosystem and contribute to continued energy efficiency. <br /><br />“New digital technology allows us to measure performance, using sensors for example, gather data and analyse phenomena more extensively than in the past. This gives us the opportunity to design new innovative services,” says Gremyr.<br /><br />Researchers working on the project have started assessing processes and needs throughout the chain from energy supplier, property owner/manager to customer, to learn key lessons which will form the basis of future energy services.<br /><br />“The idea is that the design of the services can contribute to a more sustainable society by influencing customer behaviour, for example. It is also interesting to analyse the conditions required for new types of services to become established,” Wallbaum says.<br /><br /><strong>A collaborative research approach</strong><br />The project is a pilot study which was made possible through seed funding provided by the Energy Area of Advance and the work is being undertaken in close collaboration with Göteborg Energi. <br /><br />“Here we have a great opportunity to get involved with Göteborg Energi and understand their perspective, the same goes for the customer and end-user side, and from there we try to conceptualise the service development. We don’t yet know where this will take us, there is no final template so we are navigating from our different perspectives,” Börjesson says.<br /><br />“What is clear is that this is a key issue. Everyone knows this work has to be done but just what is needed is complex. It affects different areas of expertise, systems, people, business models and technologies,” Gremyr says.<br /><br /><strong>Research spotlighted in professional education</strong><br />Future services will of course also create complexity for purchasing and procurement, something which Halldórsson has lectured on through Chalmers Professional Education. In other respects it can be seen that the service development area has not yet made much of an impact in the education provided at Chalmers.<br /><br />“There are many new subject areas which have emerged and which do not yet form part of Chalmers’ courses. But there are already educational components where these can be included, such as in degree projects, or quite simply by shining the spotlight on our research in our teaching,” says Börjesson.<br /><br /><strong>Applications in all industries</strong><br />The researchers are already aware of opportunities for continued collaboration after they have completed their pilot study. <br />“The project we are conducting on sustainability and digitalisation can be applied to other contexts. This then opens many doors – in a number of different industries,” Halldórsson says.<br /><br />They all agree that the Areas of Advance have an important role to play in promoting multidisciplinary collaboration at Chalmers. This in turn lays the foundations for an exchange of expertise and renewal.<br />“New contacts can also reduce the thresholds for collaboration in our infrastructures, where you might not always realise that you are in demand,” says Wallbaum.<br /><br />“And seed funding from the Area of Advance gives the slight nudge which makes collaboration happen,” Börjesson says.<br /><br /><br /><strong>Award winners </strong><br /><a href="/en/staff/Pages/sofia-borjesson.aspx" target="_blank">Sofia Börjesson</a>, Professor, Technology Management and Economics.

After having defended his doctoral thesis in high voltage engineering in 1987 he started working at ABB in Västerås. During his 13 years at the company he had several positions and worked as head of research, developing technology for measurements of diagnostics and monitoring of insulation systems and electrical power devices. In addition, he has invented and developed products in power generation. Most known is perhaps the Powerformer, a high voltage generator for connection to the grid without any intermediate transformer.<br /><br /><strong>Developing renewables</strong><br />Since 2000, Mats Leijon is a Professor in electrical science at Uppsala University. He has got about 1500 patents and has published more than 300 scientific articles. Developing renewable energy sources by using waves, wind and tidal currents have become his specialty. In parallel he has started the company Seabased, which plans, builds and installs complete, grid-connected wave parks at sea. Research and demonstration facilities are located outside Lysekil.<br /><br />He is now phasing out part of his many commitments to be able to take on the assignment at Chalmers.<br /><br />&quot;I look forward to combining theory and practice to a larger extent than I have been able to do previously in academia&quot;, says Mats Leijon. “Here at the division of Electrical Power Engineering, there are good laboratory activities.”<br /><br />In his opinion, setting high goals is crucial to success.<br /><br />“First of all, I'm going to familiarise myself with the research activities here, and then apply for funding to do exciting research, but it is still too early to say in what areas this will be.”<br /><br /><strong><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/E2/Profilbilder%20Elkraftteknik/Mats-Leijon_300x300px.jpg" alt="" style="margin:5px;width:250px;height:250px" />Important to do one´s homework</strong><br />“As a researcher, it is important not to limit your mind. One prerequisite is that you have done your homework and have a solid and stable knowledge base founded in basic theory”, Mats emphasises. “That gives you qualifications to take responsibility for development in society.”<br /><br />&quot;In order to implement your ideas, as an engineer, you can´t ignore what is possible to put into practice and what is commercially viable”, he states. “It is important to understand how your own research fits into the big picture.”<br /><br />He sees the conformity within academia as a problem.<br /><br />”People of the same type tend to choose the same type of solutions. The question is then if the right solutions really are highlighted? At Uppsala University, women account for about 40 percent in the field of electrical engineering. Perhaps I have some lessons learnt, that I could bring here”, Mats Leijon concludes.<br /><br />Text: Yvonne Jonsson<br /><br /><strong>Contact: </strong><a href="/en/Staff/Pages/Mats-Leijon.aspx">Mats Leijon</a>, Professor, Department of Electrical Engineering, Chalmers Fri, 16 Feb 2018 08:30:00 +0100 for new paradigm in pulping technology<p><b>​The Arne Asplund Mechanical Pulping Award 2018 has been granted to Professor Anders Karlström, Head of the department Electrical Engineering at Chalmers.</b></p>​The award is given out every two years by Arne Asplund Mechanical Pulping Award Foundation to promote the development of new technology for the manufacture of high-yield pulp. It is awarded in recognition of outstanding achievement in research and development of mechanical pulping technology.<br /><br /><span>“To receive this award is a great honor for me”, Anders Karlström says. “I have been working with this for many years and it feels fantastic to get a confirmation that the struggle really has been worthwhile.”<span style="display:inline-block"></span></span><br /><br />The justification for the award reads as follows: “Based on his deep understanding of the fundamentals of refining in mechanical and chemimechanical pulping, Anders Karlström has initiated a paradigm shift regarding the theory of refining by introducing the entropy model. This new approach offers tools to understand the interplay in the refining zone with regards to refiner operation, plate patterns and the produced pulp quality. These new findings are already in use in several production lines offering a set of possible ways to optimise quality and specific energy input.”<br /><br />The award consists of a gold medal and an honorarium of SEK 25,000. The prize ceremony will take place at the International Mechanical Pulping Conference, IMPC, in Trondheim on 29 May. <br /><br />Regarded as the &quot;Nobel Prize&quot; in the field of mechanical pulping, the Arne Asplund Mechanical Pulping Award was established in 1985 to commemorate the Swedish engineer Arne Asplund’s contribution to the pulp and paper industry worldwide. He was the inventor of the thermomechanical pulping technique, known as the defibrator-method, also called the Asplund-method, for pulping wooden chips.<br /><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release</a><br /><br /><strong>Contact:</strong> <a href="/sv/personal/Sidor/anders-karlstrom.aspx">Anders Karlström</a>, Professor and Head of the Department Electrical Engineering, Chalmers<br />Thu, 15 Feb 2018 13:00:00 +0100 charge of the largest battery research network in Europe<p><b>​​Patrik Johansson, Professor at the Department of Physics at Chalmers, has been elected new co-director of a large European battery research network – Alistore European Research Institute (Alistore-ERI).</b></p><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Patrik_Johansson200x270.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />The network is the largest academic-industrial collaboration on batteries in Europe and aims to tackle battery challenges and move towards sustainable energy solutions.

The seminar brings together world-leading researchers from several science disciplines to present the latest advances within the field.</b></p>​ <br />The conference gathers distinguished researchers, industry representatives, decision makers and an engaged public for presentations and discussions on future energy solutions. Development of sustainable technologies for solar energy, batteries and energy storage is needed to make the necessary switch from fossil fuels to renewable energy sources. During the conference, the latest advances in the field will be highlighted, and the content will be made available to the public. Through live broadcast at <a href="" target="_blank">Molecular Frontiers YouTube Channel</a>  you will be able to follow the conference even if you are not in place. <br /><br /><br /><strong>150 high school students participate</strong><br />Sustainable Energy Symposium is a unique event in several ways – about half of the conference participants are high school students. This is possible thanks to the Molecular Frontiers Foundation which offers a scholarship for students from all over the country to come. The Molecular Frontiers emphasize in particular the importance of being curious and asking good questions. Approximately 150 students from all over the country are given the opportunity to listen to and ask questions to world-leading researchers.<br /><br /><br />Among the speakers are noted:<br /><br /><strong>Steven Chu, Nobel Prize winner in Physics 1997 and Obama's Energy Ministers 2009-2013.</strong><br />Steven Chu was awarded the Nobel Prize in Physics in 1997 for his work on laser cooling of atoms. Since then, his research has increasingly been about solving the challenges of climate change and sustainable energy supply. In 2009, Barack Obama appointed him the United States Secretary of Energy, and became the first scientist in an American government. After his time as Energy Secretary, he returned to research but remains a prominent debater focusing on renewable energy and nuclear power. He emphasizes the importance of reducing fossil fuel use to address global warming and climate change. He has put forward a number of innovative and sometimes controversial proposals for action.<br /><br /><strong>Paul Alivisatos, University of California at Berkeley</strong><br />Paul Alivisatos is a pioneer in nanotechnology, focusing on inorganic nanocrystals. By controlling the size and surface of the nanocrystals, his research team can tailor their properties and produce materials for a variety of applications, including solar cells and materials to reduce carbon dioxide into hydrocarbons. He has developed quantum dots, small semiconductors that are isolated from the environment and are extremely effective in absorbing and transmitting light. These are already used in the most energy efficient and high quality television screens in market today.<br /><br /><strong>Daniel Nocera, Harvard University</strong><br />Two inventions of Daniel Nocera may be of great importance in the future. The artificial leaf, mentioned in Time magazine’s list of Inventions of the Year 2011, mimics the photosynthesis, and splits water into hydrogen and oxygen by using sunlight. A further development of the concept is the bionic leaf, which takes carbon dioxide from the air and combines it with hydrogen from the artificial leaf to produce biomass and liquid fuel. In this way, a cycle is achieved that is much more efficient than photosynthesis in nature, which can contribute to a green and cheap production of fuel and food.<br /><br /><br /><strong>Program</strong><br /><a href="/en/conference/sustainableenergy/Documents/Program_Sustainable_Energy.pdf" target="_blank">Here you will find the entire program for the conference &gt;</a><br /><br /><br />Plenary lectures 7-8 December:<br />• <strong>Steven Chu</strong> – <em>Climate Change and innovative paths to a sustainable future</em><br />Nobel laureate in Physics 1997, former United States Secretary of Energy.

Selma Brynolf is coordinator for the profile Sustainable Vehicle Technologies within Chalmers Areas of Advance Transport and Energy.</b></p>​“It's an exciting assignment and I look forward to learning more about the research on transport and sustainable vehicles that is conducted at Chalmers and University of Gothenburg.”<br /><br />As post-doc at the department of Space, Earth and Environment at Chalmers, Selma Brynolf has evaluated the environmental impact of marine fuels from a lifecycle perspective and worked with modeling of energy systems. Since October 2017, she will also coordinate Sustainable Vehicle Technologies, a profile shared between the Areas of Advance Transport and Energy. She will work together with Anders Nordelöf, who continues his assignment as vice coordinator.<br /><br />“I currently work with two main questions”, says Selma Brynolf. “Evaluation of possible future fuels and propulsion technologies for shipping, as well as the role that fuels produced from carbon dioxide and water using electricity could have in the transport sector.<br /><br />Maria Grahn, previous coordinator of Sustainable Vehicle Technologies, is now director of Chalmers Energy Area of Advance.<br /><br />“I am pleased and proud to announce a new, strong leadership for Sustainable Vehicle Technologies. Handing over to Selma Brynolf and Anders Nordelöf feels very good, I am certain that the work will be continued in the best possible way.”<br /><br />Selma points out that an important and challenging part of her research is to find sustainable solutions for all modes of transport. She believes that electrification is a possibility for many parts of the transport sector, not just for cars, and that it is very exciting to follow the development.<br /><br />“But there are many more areas that need to be developed. I also believe that we need to think again and change our view of transport in general and the benefit they give us. I hope to contribute to a slightly more sustainable transport sector.”<br /><br />Text: Julia Jansson och Emilia Lundgren<br />Fri, 03 Nov 2017 10:05:00 +0100
