Barack Obama discussed fuel cells at KTH Royal Institute of Technology

During his visit to Sweden, Barack Obama met Göran Lindbergh, professor of applied electrochemistry at KTH Royal Institute of Technology and leader of the thematic area Energy Storage at SHC. The American president asked the researchers about practical applications for fuel cells.

– A once-in-a-lifetime opportunity, says Göran Lindbergh, who hopes that the visit will lead to greater international ventures.

President Obama visited KTH on Wednesday in the company of Prime Minister Fredrik Reinfeldt and the Minister for Information Technology and Energy, Anna-Karin Hatt. Lindbergh’s research colleagues Carina Lagergren and Rakel Wreland Lindström were also present to demonstrate the fuel cell research.

Sleipner, the fuel cell car constructed by KTH students, was used by Göran Lindbergh as an example of how fuel cell technology can be put into practice. Sleipner can run 1.500 kms on hydrogene gas containing energy equivalent to 1 litre of gasoline.

– I think it is important to give concrete examples of how fuel cells can be used for sustainable transport systems, he says. From a research point of view as well as a way of illustrating how the knowledge can be transferred to a student level.

During the ten minutes that Obama spent with the researchers, the president was also shown a fuel cell that uses olive oil production residues to produce electricity, and the mobile phone charger PowerTrekk that is charged by tap water.

– We are very pleased with the event. Now let´s hope that this will benefit the environmental technology research at KTH in general, and also attract more students, says Göran Lindbergh.

Five questions for Sonja Tidblad Lundmark

She is one of the SHC researchers within the area of Electrical machines and drives, and takes an interest in unusual machines with uncommon materials. Sonja Tidblad Lundmark recently held her docent lecture in electric power engineering, entitled Electric motor drives for traction applications considering recycling aspects.

Sonja Tidblad Lundmark

Why did you begin doing research about electrical machines?
My interest originated in the nuclear power debate. I wanted to contribute to the usage of other energy sources, and to make my research useful for the creation of a sustainable society. Currently, wind power and electric vehicles are the main areas of progress, but there are several other interesting applications. For example, I have previously worked with new and more efficient transformers.

Your research is about electric and hybrid vehicles and wind power generators. What do you focus on?
I concentrate mainly on slightly unusual machines, so called transversal flux machines and claw-pole machines. This type of machines is still fairly uncommon in hybrid vehicles. What makes them interesting is the fact that they are high performing despite their relatively small size. Moreover, they offer the possibility to use different, more environmentally-friendly materials, which facilitate recycling. I look at efficiency, power and torque density and fault tolerance, and have started to investigate thermal modeling, among other things to reduce the effect of thermal variations on the permanent magnets in the machines.

Why is recycling such an important aspect for electrical machines in vehicles?
The materials used in electrical machines are mainly copper or aluminium, steel laminations or pressed iron powder and permanent magnets. For some of these materials the supply is limited and the price very high. This makes it interesting to make reduced consumption and recycling a part of the design process.

Tell us about a recent fun experience in your research!
I recently published an article together with a fellow researcher, where we compared a Toyota Prius motor to a transversal flux machine. Our conclusion was that using a transversal flux machine instead of a traditional machine offers certain advantages. Among other things, a smaller amount of copper can be used in the manufacturing process, while maintaining a slightly higher efficiency.

But my work is fun in many ways, above all the interaction between research and education, and following the progress of students and doctoral students!

How does the future look for electric vehicle research?
There is a good deal left to be done, for academia as well as for industry. A lot of the work concerns charging – charging an electric vehicle should be quickly and easily done. In my research group, we have begun to look into the possibilities of wireless charging.

Sonja Tidblad Lundmark is a docent at the division of Electric power engineering at the department of Energy and environment, Chalmers University of Technology.

Mahindra visited SHC

The Indian vehicle manufacturer Mahindra visited SHC at Chalmers yesterday, to learn about the hybrid and electric vehicle research and to investigate the possibilities for future cooperation and exchange of knowledge.

– Meeting Mahindra was exciting and interesting, said Elna Holmberg, manager of SHC. They are looking for partners to share knowledge in topics which the SHC researchers address on a daily basis. For example, the cost of batteries is one of their big challenges.

During the meeting, the Mahindra representatives gave a presentation of the company, whose activities range from vehicles to IT and defense, putting emphasis on their efforts in the area of electric vehicles. Elna Holmberg described the work within SHC and Torbjörn Thiringer talked about Chalmers’ electric power research.

Saeid Haghbin was also present to give a summary of his PhD research project, carried out within SHC. Finally, the group went to see the lab where important activities within the SHC research theme “Electrical machines and drives” are conducted.
