A passion for developing an environmentally friendly fuel

"We are facing a disaster if we continue to release carbon dioxide into the atmosphere. Society depends on energy, but we cannot continue to use fossil fuels forever. This is why I am extremely interested in research into a renewable way of manufacturing fuel using solar energy,” says Jianwu Sun, Associate Professor at the Department of Physics, Chemistry, and Biology at Linköping University in Sweden.

Water + carbon dioxide + sunlight = fuel. Aptly named Associate Professor Sun is working on an approach that may be able to reduce the emission of carbon dioxide (CO2) to the atmosphere. He was recently awarded a grant from Formas, the Swedish Research Council for Sustainable Development, for the research projects of future research leaders.

He will use the coming years to develop a novel method to convert carbon dioxide and water into chemical substances, such as ethanol, methane, and other hydrocarbons, that can be used as fuel. The process will be driven by energy from the sun.

The efficient conversion of carbon dioxide and water to fuel may be able to contribute to reducing carbon dioxide emissions to the atmosphere. Jianwu Sun recently received a SEK 3 million (≈ EUR 311 000) research grant from Formas for his work.

No one has managed this in an efficient way previously, so it’s an exciting challenge. The grant from Formas will enable me to start my own research group. When I first got the news of the grant I became highly excited. I immediately started to think about the practicalities of carrying out the project effectively. I will probably take on a doctoral student or postdoc for the project, said Jianwu Sun.

Enticed back to the academic world

Jianwu Sun has worked in China, France, Belgium, and Sweden during the past 10 years. He has had time to experience what it’s like to carry out research not only at universities but also in more industry-oriented environments. Both types of research environments have advantages, he believes.

The greatest difference is that in industrial research you are closer to the application in practice, and can see the effects of your contribution more directly. I am also greatly impressed by the highly efficient and close collaboration in the industrial-oriented research environment. But as a researcher in industry, you don’t have the same possibility to follow the research direction in which you are most interested, Jianwu Sun explained.

The freedom to influence the direction of his own research is a strong argument for Jianwu Sun. After research for some years in industry, he was enticed back to the academic world, partially for this reason. But his time working in industrial research included many valuable experiences.

When I worked as a senior researcher at the IMEC in Belgium, which is the world-leading research hub in nanoelectronics and digital technologies, we had very dense meetings, fruitful discussions, and extensive collaborations. I was very impressed by the excellent communication skills of some colleagues. Indeed, I have learned a lot from that experience,  said

Stimulating diversity at LiU

Several factors contributed to Jianwu Sun choosing LiU as the place to carry out his research. One factor is that LiU has world-leading research in materials science, in particular in the development of silicon carbide, which Jianwu Sun wants to explore in his work to use solar energy to produce fuels.

But the factor that he mentions first is the social environment. Jianwu Sun believes that diversity is a characteristic of a healthy research environment. This is true not only when the researchers come from different countries, but also when there is a productive mixture of the research topics that the researchers are working on.

I noticed that LiU is much more international than other universities where I have worked in France and China. In our division, we have researchers from Thailand, Lithuania, Vietnam, and many other countries. I’m convinced that the mixture is very good for research. People in a productive research environment must also have open minds and they must be willing to share ideas and experiences. This leads to fruitful discussions and people inspiring each other ended Jianwu Sun.
