But on the matter of if one or more choices of fuels would be the route for the future, the debate revealed a quite pronouced concensus. The conclusion that choosing one single fuel alternative in the future will probably show itself very difficult and problematic, appeard quite unanimous, and the seminar instead expressed the probable need for two or more different fuel options.<br /></p> <p>  </p> <p><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Areas%20of%20Advance/Energy/lunchseminarier/IMG_0221_Lunchsem-180426_medSamtycke_SOE0001_350x305px.jpg" alt="" style="margin:5px" /></p> <p><em>From left to right: Markus Norström, RISE, Jonas Sjöblom, Maria Grahn och Frances Sprei, Chalmers, Johanna Mossberg och Patrik Klintbom, RISE, Selma Brynolf, Chalmers samt Karin Pettersson, RISE.</em></p> <h6 class="chalmersElement-H6"><em> </em></h6><p><br /></p> <p><br /></p> <p><br /></p> <p><br /></p> <br /><p><br /></p> <p><br /></p> <p><a href="/en/areas-of-advance/energy/events/Pages/Electricity-and-Biofuels_Do-we-need-both.aspx">Agenda »<br /></a></p> <p>Presentation materials:<em><br /></em></p> <p><em>Maria Grahn:</em> <a href="/SiteCollectionDocuments/SO%20Energi/Maria-Grahn_Pres_The-role-of-biofuels-electrofuels-and--180426.pdf">The role of biofuels, electrofuels and electricity in the transformation of the transport sector. »</a></p> <p><em>Patrik Klintbom: </em><a href="/SiteCollectionDocuments/SO%20Energi/Patrik-Klintbom_Pres_Electricity-and-biofuels-synergies-and-competition_180426.pdf">Electricity and biofuels – synergies and competition. »</a></p>Fri, 04 May 2018 14:00:00 +0200 to design for future scenarios<p><b>​Autonomous cars and smart homes will, in the near future, most likely will be a part of our daily lives. But how can we design these systems in a human centred way when they haven’t yet been fully implemented in the society? This was the topic when over 60 practitioners, within the User Experience community GotUX, showed up at the Virtual Development Laboratory at Chalmers.</b></p><div>To have a good understanding of user-centric design in future systems is important for many reasons. One is to avoid technological lock-ins that may not even be desired from a human perspective. These lock-ins can then be very hard to change at a later stage. Feelings of unsafety and mistrust can lead to distress, misuse and avoidance. Including everyday people in the making of big technological systems, influencing our daily lives, can also be argued to be a democratic issue.</div> <div> </div> <h3 class="chalmersElement-H3">Trust in future autonomous vehicles</h3> <div>Imagine yourself sitting in an autonomous car that breaks harshly every time it stops. Even though this doesn’t mean that the car is unsafe the behavior can still make us feel discomfort and mistrust. PhD students, Fredrik Ekman and Mikael Johansson, have done experimental studies about how people perceive different behaviours of autonomous cars, and concluded that defensive and predictable driving felt safer. This knowledge is important because the autonomous cars can then be designed not only to be safe, but also make us feel safe. One could think that as long as a system is safe our feelings of comfort and trust are irrelevant, but if we don’t trust a system we might not use it the way it’s intended, and the risks for accidents or failure increases. Should we distrust the system entirely we would most likely not adopt it at all. </div> <div><div> </div> <h3 class="chalmersElement-H3">Using generative techniques in designing Smart Energy Systems</h3> <div><img class="chalmersPosition-FloatLeft" alt="Bild på Sara Renström" src="/SiteCollectionImages/Institutioner/IMS/Design%20and%20Human%20Factors/Sara%20Renström%20350pxl.jpg" style="height:307px;width:346px;margin:5px 15px" />Surveys and interviews are familiar techniques when trying to understand human thoughts. However the knowledge retrieved is sometimes just too shallow.  Sara Renström, PhD student specialized in user-centred sustainable design, has been using crafting of collages and drawing as a way of reaching more tacit and latent feelings and thoughts. This in the effort of trying to understand what roles people want to play in smart energy systems, and what products, services and systems that could support these roles. Sara explains how she invited residents from the HSB living lab for a workshop including pizza, candy and crafting. <br /><br />Afterwards the collages were presented to the rest of the group members revealing interesting experiences, and was followed by thoughtful discussions, helping contextualizing smart energy technologies in participants’ lives.</div> <div> </div> <div>The discussions on design and user experience continued after the presentations when the host, Graduate school Human Technology and Design, offered everyone snacks, drinks and mingle.</div> <div> </div></div> <h4 class="chalmersElement-H4">Facts</h4> <div>GOTUX is local chapter of the Interaction Design Association, IXDA, a member-supported organization dedicated to the discipline of interaction design. <a href=""></a></div> <div><br /><a href="">The graduate school Human Technology and Design</a> is common in the two departments Industrial and Materials Science and Computer Science and Engineering.

The interest in cooperation within the field has increased, both in the automotive industry and from other universities, in the Gothenburg region as well as internationally.<br /><br />&quot;It is great that our research is gaining recognition,&quot; says Jonas Sjöberg. “I have been able to form a research group with young researchers, who have taken on new research challenges in a new and growing field.”<br /><br /><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Aktiv%20trafiksäkerhet%20gav%20Volvostipendium/Jonas_Sjöberg_300px.jpg" alt="Jonas Sjöberg" class="chalmersPosition-FloatRight" style="margin:5px;width:230px;height:300px" />In the justification for the scholarship, it is emphasized that Jonas Sjöberg successfully has developed the field of electromobility and autonomous driving. Together with his research group, and often in cooperation with other researchers at the Department of Electrical Engineering, he has worked with system aspects, dimensioning, modeling and control of hybrid drive lines. The results have enabled more exact calculations of the &quot;best&quot; design for challenges in electromobility and how to control the energy management in the vehicle, which previously relied on rough estimates.<br /><br />One of the industrial PhD student projects that Jonas has been engaged in, within the Intelligent Vehicle Safety System Program, has resulted in a patent, which subsequently has been applied in newer Volvo cars where a system of emergency braking helps avoiding accidents in left-hand turns. <br /><br />His research in recent years has been focused on issues concerning autonomous driving.<br /><br />&quot;What appeals the most to me within this research area is that we constantly are faced with so multifaceted and complex problems, that for every new progress there is always more to understand,&quot; says Jonas Sjöberg. “It is also important to constantly have the interaction between human beings and technology in focus.”<br /><br /><strong>Prize ceremony and seminar</strong><br />On 29 May, the prize ceremony will be held where Jonas Sjöberg is awarded the 2017 Håkan Frisinger scholarship. In connection with this, he will give a lecture in Swedish entitled ”Historien bakom avancerad forskning: från neuronnät till självkörande bilar”.<br /><br />&quot;I´m honored to receive the scholarship,&quot; he says. “During the lecture I intend to talk about how my research has evolved up to today and how coincidences sometimes can play a role.”<br /><br />Besides Jonas Sjöberg, you also have the opportunity to listen to Bo Wahlberg, Professor in automatic control at KTH, Nikolce Murgovski, Assistant Professor in mechatronics at Chalmers, and Erik Coelingh, technology advisor at Zenuity AB and Adjunct Professor at Chalmers.

A common cause is when the vehicle has been hit in the rear. Many of these accidents could be avoided by driving an electric car. How this could be done is shown in Adithya Arikere’s PhD thesis.</b></p><div><span style="background-color:initial">“In my project, we tried to find novel active safety applications for electrified drivetrains that cannot be achieved or at least performed as well with traditional internal combustion engines” says Adithya Arikere.</span><br /></div> <div><br /></div> <div>Electric drives have a lot of advantages over internal combustion engines. They have fast and reliable response, precise and accurate control, max torque from standstill and more. Some of these can be exploited to achieve novel or improved active safety functionality. </div> <div><br /></div> <div>&quot;A simple example is if you can detect that you are about to be hit from behind and you have the free space in front to accelerate and get out the way, you can do so with an electrified drivetrain&quot; says Adithya Arikere. </div> <div><br /></div> <div>This cannot be done reliably with an internal combustion engine since they have poor low-end torque, large response times and the transmission can be in the wrong gear. But with electric drives which deliver their peak torque at low speeds, have short response times and typically don’t need a transmission, this can be easily and reliably achieved. Adithya Arikere has investigated three scenarios in detail: the rear-end collision, obstacle avoidance with oncoming traffic and intersection accidents. </div> <div><br /></div> <div>&quot;We have found that in each case, the quick and reliable response of electric drives can be used to perform interventions that can avoid or mitigate accidents and yield a significant safety benefit&quot; says Adithya Arikere</div> <div><br /></div> <div>Since his project deals with finding novel active safety applications for electrified drivetrains he believes it can make electrified vehicles of the future safer and consequently, also make them more attractive to consumers since these safety functions cannot be achieved with traditional internal combustion engine based vehicles.

All with a focus on components and systems studies for electromobility.  Jonas Fredriksson, Professor in electrical engineering, explains.</b></p><strong>​Who is the summer school intended for?</strong><br />It is intended primarily for PhD students with interest and research profile in electromobility, at all Swedish universities. However, researchers from the Centre’s industrial partners are also welcome.<br /><br /><strong>Why do you arrange a summer school?</strong><br />Swedish Electromobility Centre is a national centre of excellence with doctoral students and researchers at several Swedish universities. This means that common activities lead to a lot of traveling for some members. In the summer school we gather in one place for a week and study and discuss electromobility focused together. In addition, participants get the opportunity to get to know each other and create contacts with other researchers and research students who deal with different aspects of electric mobility.<br /><br /><strong>What will I learn during the week?</strong><br />The course gives both overview and in-depth knowledge of key components such as batteries, fuel cells and electrical machines as well as tools for systems studies that will be used for evaluation, design and construction of vehicle drive systems.<br /> <br /><strong>Why should I attend – aren’t the courses I take at my university enough?</strong><br />Courses taken within your own research school are usually in-depth courses within your research area. Because electromobility is an interdisciplinary research field, finding courses that provide a comprehensive picture can be difficult. The summer school provides both a broader understanding of the electromobility area and of where the research challenges lie within the different parts of the area.<br /><br /><strong>I want to participate. How do I proceed?</strong><br />You register for the course at Swedish Electromobility Centre’s website. The course itself and course material are free, but you pay for travel, accommodation and living. During an intensive week, lectures and practical exercises are mixed with social activities. The examination consists of active participation during the week as well as the solution of a project assignment that will be reported on a separate occasion.<br /><br /><strong>Swedish Electromobility Center summer school: Components and systems for electromobility</strong><br /><strong>When</strong>: 21-25 May 2018<br /><strong>Where</strong>: <a href="">Toftaholm</a>, outside Värnamo.<br /><strong>Registration</strong>: By April 12th<br /><a href="">Read more about the summer school and register &gt;&gt;</a><br />Thu, 29 Mar 2018 00:00:00 +0200 lunch seminar on FFI-projects<p><b>​When Areas of Advance Transport and Energy invited to a lunch seminar on successful, industry relevant research projects, focus on FFI, it became apparent that the subject is interesting - even when the amount of available seats was doubled the seminar was fully booked within short.</b></p>Areas of Advance Transport and Energy last week welcomed Peter Kasche, from the Swedish Ministry of Energy, and Lars Davidson, from the department of Mechanic and Maritime sciences, to a lunch seminar on the subject successful, industry relevant research projects, focus on FFI.

A database is now being published that charts the metals and facilitates recycling. On 8 March Maria Ljunggren Söderman, researcher at Chalmers University of Technology, will present the results at IEA&#39;s expert meeting.</b></p><div>Metals, such as gold, cobalt and lithium, are an indispensable part of our batteries, mobile phones, electronic gadgets and vehicles. At the same time, Europe is highly dependent on imports of metals, which makes some of them critical for the EU.</div> <div> </div> <div>&quot;These metals are required for the ongoing transition to greener technologies, such as electric cars, solar cells, LED lighting and wind power, so any supply risks are a strategic and economic problem for the EU. What's more, these are finite resources that must be used in a sustainable way,&quot; says Maria Ljunggren Söderman, Researcher at Environmental Systems Analysis at Chalmers University of Technology.</div> <div> </div> <div>She is part of the extensive European research project Prosum, which has now compiled a new database with which to address the problem. The Urban Mine Platform - the only one of its kind in the world - charts what is known as the urban mine: the metals that are already in circulation and could be recycled from our end-of-life vehicles and electrical and electronic equipment.</div> <div> </div> <div>Maria Ljunggren Söderman has been responsible for the survey of the 260 million light-duty vehicles in Europe's vehicle fleet. She notes that the quantities of critical and scarce metals have increased substantially and that vehicles also now include many new metals.</div> <div> </div> <div>&quot;This is mainly because we are constructing increasingly advanced vehicles, with a great deal of electronics, lightweight materials and catalytic converters. The increase in the numbers of electric vehicles adds to this development, even though they so far represent a small proportion of the vehicle fleet,&quot; she says.</div> <div> </div> <div>One such example is neodymium, one of the rare earth metals (REM). It is estimated that by 2020 there will be nearly 18,000 tonnes of neodymium in the active vehicle fleet - nine times the amount present in the year 2000.</div> <div> </div> <div>Gold is another example - and the researchers were surprised by just how vast the quantities of hidden gold in our vehicles actually are. In 2015 there were an estimated 400 or so tonnes of gold in Europe's vehicle fleet, while the vehicles that left the fleet contained in the region of 20 tonnes of gold - which, in addition, was not recycled.</div> <div> </div> <div>This means that gold worth many hundreds of millions of euros is wasted - each year</div> <div> </div> <div>&quot;Our calculation shows that that the quantity of gold in end-of-life vehicles is now in the same order of magnitude as the quantity of electrical and electronic scrap. This is an increase that cannot be ignored,&quot; Ljunggren Söderman says.</div> <br /><img src="/en/departments/tme/news/Documents/Maria-L-Soderman_750x340.jpg" alt="Maria-L-Soderman_750x340.jpg" style="margin:5px" /><br /><strong><sup>Charting the gold that is wasted.</sup></strong><sup> The proportion of gold and other critical and scarce metals in vehicles has increased substantially in Europe. &quot;I don't think people are aware that they have such a large part of the periodic table in their cars,&quot; says Maria Ljunggren Söderman at Chalmers.</sup><br /><br /> <div>In general very little of the critical and scarce metals in vehicles is recycled. The major challenge is that they are spread out in small quantities; in a new car, for example, there may be a gram or two of gold distributed over several tens of components.</div> <div> </div> <div>But while the EU has clear requirements for the recycling of precious metals in electrical and electronic equipment, such stipulations are lacking as regards vehicles.</div> <div> </div> <div>&quot;There are no requirements or incentives for recycling gold from vehicles, but there are clear economic values here that I don't think people have realised the extent of,&quot; she says.</div> <div> </div> <div>She hopes that the research findings will spur on a change.</div> <div> </div> <div>&quot;Automotive manufacturers and the recycling and material industries need to work together to ensure that something happens. It must be possible to do more than at present - after all, this has been achieved with electrical and electronic equipment,&quot; she says.</div> <div> </div> <div>&quot;Having said that, gold is a comparatively low-hanging fruit, and the prospects for recycling other critical and scarce metals are significantly less favourable - from both electronics and electronic equipment and vehicles. If we want to alter this, policy changes may be necessary.&quot;</div> <div> </div> <div>On 8 March she will present her research findings at an expert meeting on material trends and climate change within the area of transport, organised by the IEA, the International Energy Agency of the OECD countries. She emphasises that a change towards more recycling of metals is a key part of the EU's efforts to create a more circular economy.</div> <div> </div> <div>&quot;The critical and scarce metals in our products have increased substantially, and in most cases, we only use them once. This must be addressed, especially because these metals are required for many of the sustainable technological solutions that we currently have on the table,&quot; she says.</div> <div> </div> <h4 class="chalmersElement-H4">FACTS<br />The database that charts Europe's urban mine</h4> <p></p> <ul><li>In the international EU project Prosum (Prospecting Secondary raw materials in the Urban mine and Mining wastes) 17 parties from universities, research institutes and expert organisations have together surveyed the quantities of critical and scarce metals that can be recycled from Europe's batteries, vehicles and electrical and electronic.

Two self-driving mining vehicles are now to be developed in a recently launched project with Chalmers as one of the partners.</b></p><div>​“Self-driving vehicles are important in the mining industry for several reasons,” says Mattias Wahde, professor in vehicle engineering and autonomous systems at Chalmers. “One important reason is that you want to minimize the risk of personal injuries by having as few people as possible in the mine. With self-driving vehicles, staff can control and monitor machinery and equipment from a control room.”</div> <div> </div> <div>Self-driving vehicles can also increase the efficiency, for example through minimized waiting times for the various vehicles in the mine. To this end, Mattias Wahde and his research group will develop algorithms for route planning and coordination, both in the mine and for transport from the mine.</div> <div> </div> <h4 class="chalmersElement-H4">A safe and fully automated transport system</h4> <div>The purpose of the project is to build a safe and efficient fully automated transport system, able to navigate in narrow spaces such as mines, but also on public roads. The material from the mine can thus be transported without a driver in the vehicle, all the way from the mining area to the enrichment plant. The system should be able to work both with and without support from various infrastructure systems such as GPS, WiFi and 4G.</div> <div> </div> <h4 class="chalmersElement-H4">Two self-driving vehicles with high traffic safety</h4> <div>Two different transport systems of self-driving trucks will be developed in the project. Both will provide high traffic safety as well as optimized use of the vehicles for mining. The existing infrastructure of the mining area will to a certain extent be adapted to the vehicles.</div> <div> </div> <div>One of the two vehicles will transport ore from the mine to the surface. The ore will then be transported from the transshipment site at the mine to the enrichment facility by the second vehicle, a self-driving truck with trailer. The transports will be monitored via a traffic management system.</div> <div> </div> <div> </div> <div><strong>FACTS: Auto pilot site to plant</strong></div> <div>The project Auto pilot site to plant is running until March 2019.

Furniture and plants ordered, the passengers can soon start enjoying their new living room.<br /><br />The facelift of the bus stop is part of a study that investigates how drivers and passengers experience the electric buses and the bus stops. According to Pontus Wallgren, both buses and stops received high marks. Among other things, the buses are considered well adapted for persons with reduced mobility, and easy to drive smoothly and comfortably.<br /><br />The time required for charging at end stops is a challenge for public transport planners. Route 55 is relatively short, about 25 minutes, and the buses need to charge for three to four minutes. However, the timetable has a margin of ten minutes between the trips.<br /><br />&quot;The drivers see the break as an advantage. They say it reduces stress and back pain and makes them more alert while driving&quot;, concludes Pontus Wallgren.<br /><br />The results of the study will be presented at a seminar at Chalmers on January 24, 2018. <a href="/en/departments/ims/calendar/Pages/EBSF_2-Gothenburg-demo-showcase.aspx">Sign up here &gt;&gt;</a><br /><br /><strong>FACTS ABOUT THE STUDY</strong><br />The study is part of <a href="">European Bus System of the Future 2</a>, a project led by the <a href="">International Association of Public Transport</a> and partly financed by the EU Horizon 2020 program.<br />The study was conducted by Pontus Wallgren, Oskar Rexfelt, Victor Bergh Alvergren, MariAnne Karlsson and Erik Ohlson, Chalmers.<br /><em>Contact</em>: Pontus Wallgren, +46 31 772 13 97, <a href=""></a><br /><br /><strong>FACTS ABOUT ELECTRICITY</strong><br /><a href="">ElectriCity</a> has run in Gothenburg since 2015 and is a collaboration between industry, academia and society where the participants develop and test solutions for tomorrow's sustainable public transport.

During my leave, I have had the opportunity to reflect on what we have achieved in 2017, and I feel proud that we have accomplished a great deal in transport research and utilization.<br /><br />Much effort has been made to create a better model for interdisciplinary transport research within the Area of Advance Transport. This has led to our thematic areas - Electromobility, Autonomous transportation and the Transition to future transport systems. I think they are a good way of working with transport challenges across disciplinary or institutional boundaries and for Chalmers and University of Gothenburg to collaborate.<br /><br />Another major activity has been to build international partnerships with a few selected universities in the world that can complement us and strengthen our research, utilization and education. This has already led to two strategic partnerships, one in the United States and one in Belgium, and the management group is now working to create a similar partnership in China. These partnerships are carefully selected to complement our resources and competencies. At the same time we expand our existing partnerships across disciplines, and our industrial partnerships or training programs. Our hope is that the effects of these partnerships will soon be felt in the form of new opportunities for exchange of researchers and students, joint workshops and conferences, opportunities for research and education with shared resources and joint research projects.<br /><br />Since the start of the Areas of Advance, Transport has focused on getting new young researchers at Chalmers through postdoc funding. In 2017 we continued this initiative with 17 new researchers in interdisciplinary transport projects.<br /><br />We have arranged a highly appreciated initiative seminar, and received a lot of appreciation for engaging academy, industry and public authorities in the question of the transition to future transport systems. Of course, this is to a great extent thanks to the quality of the research we do at Chalmers and University of Gothenburg. It is important that we strengthen this cooperation even more with joint projects and common working methods in order to get the best effects.<br /><br />No one has probably missed Chalmers's review of the Areas of Advance, and I am pleased that the investigation has shown that the Area of Advance Transport is functioning well, is considered important and will continue without major changes.<br /><br />Now by the end of January, I notice that the gray days begin to get brighter and there is a lot going on in the transport area. We have already begun planning for our research days, lunch seminars and initiative seminars and I hope we will soon meet at one of these activities.<br /><br /><br /><br /><br />Wed, 10 Jan 2018 00:00:00 +0100 thesis could make a more fuel efficient aircraft possible<p><b>Lowering of fuel consumption and emissions is of paramount importance in the aerospace industry but the aircraft engine is a complex system. The different parts are dependent on each other and it’s difficult to determine which component to take care of first and foremost to make the aircraft engine more efficient. Oskar Thulin deals with this in his PhD thesis ”On the analysis of energy efficient aircraft engines”</b></p><div><div>The aircraft engine consists of many integral components and each component will influence the overall performance of the system. Furthermore, the aircraft engine has weight and contributes to drag that must be compensated for by the engine. Using the regular way to assess performance, it is impossible to compare one component's loss to another or to directly relate an individual component's loss to the overall loss. Oskar Thulin has developed an analytical method that makes it possible to directly compare component losses in a system perspective. The method also makes it possible to include weight or caused drag in the analysis.</div> <div><br /></div> <div>&quot;This gives a much more clear picture of how big the losses are for the various components, as well as for each component type&quot; says Oskar Thulin.</div> <div><br /></div> <div>The developed framework is used to study various aircraft engines. In general, it can be said that the hot exhaust gases that leave the engine, the combustion process in itself, and the part of the kinetic energy in the exhaust that is not used to propel the aircraft forward, are the main sources of the overall loss.</div> <div><br /></div> <div>&quot;Based on the analysis you can discuss different technologies that can do something about these dominant losses. This enables a future more fuel-efficient airplane, says Oskar Thulin, who will present his PhD thesis at Chalmers University of Technology<a href="/en/departments/m2/calendar/Pages/On-the-analysis-of-energy-efficient-aircraft-engines.aspx"> on December 6 at 10:00 in HB4. </a></div></div> <div>​<br /></div> Fri, 01 Dec 2017 15:00:00 +0100
