Over the last few years, a specially designed molecule and an energy system with unique abilities for capturing and storing solar power have been developed by a group of researchers from Chalmers University of Technology in Sweden. Now, an EU project led by Chalmers will develop prototypes of the new technology for larger scale applications, such as heating systems in residential houses. The project has been granted 4.3 million Euros from the EU.

In order to make full use of solar energy, we need to be able to store and release it on demand. In several scientific articles over the last few years, a group of researchers from Chalmers University of Technology have demonstrated how their specially designed molecule and solar energy system, named MOST (Molecular Solar Thermal Energy Storage System), can offer a solution to that challenge and become a vital tool in the conversion to fossil-free energy.

The technology has generated great interest worldwide. With the , solar energy can be captured, stored for up to 18 years, transported without any major losses, and later released as heat when and where it is needed. The results achieved in the lab by the researchers are clear, but now more experience is needed to see how MOST can be used in real applications and at a larger scale.

“The goal for this EU-project is to develop prototypes of MOST technology to verify potential for large-scale production, and to improve functionality of the system,” says Kasper Moth-Poulsen, coordinator of the project, and Professor and research leader at the Department for Chemistry and Chemical Engineering at Chalmers.

Pushing towards products for real applications

Within the project, the technology will be developed to become more efficient, less expensive and greener, thereby pushing towards products that can be used for real applications. Strong research teams from universities and institutes in Sweden, Denmark, the United Kingdom, Spain and Germany will connect and work together.

“A very exciting aspect of the project is how we are combining excellent interdisciplinary research in molecule design along with knowledge in hybrid technology for energy capture, heat-release and low-energy building design,” says Kasper Moth-Poulsen.

Using the molecule in blinds and windows

Advances in the development of MOST technology have so far exceeded all expectations. The first, very simple – yet successful – demonstrations took place in Chalmers’ laboratories. Among other things, the researchers used the technology in a window film to even out the temperature on sunny and hot days and create a more pleasant indoor climate. Outside the EU project, application of the molecule in blinds and windows has begun, through the spin-off company Solartes AB.

“With this funding, the development we can now do in the MOST project may lead to new solar driven and emissions-free solutions for heating in residential and industrial applications. This project is heading into a very important and exciting stage,” says Kasper Moth-Poulsen.

More about: The EU project

The EU project, which is also named Molecular Solar Thermal Energy Storage Systems, will extend over 3.5 years and has been allocated 4.3 million Euros. Partners in the project Include: Chalmers University of Technology, University of Copenhagen, University of Rioja, Fraunhofer Institute, ZAE Bayern and Johnson Matthey. At Chalmers, researchers from the Department of Chemistry and Chemical Engineering and the Department of Architecture and Civil Engineering will participate.

Chalmers University of Technology SE (Swedish: Chalmers tekniska högskola, often shortened to Chalmers) is a Swedish university located in Gothenburg that focuses on research and education in technology, natural science, architecture, maritime and other management areas

The University was founded in 1829 following a donation by William Chalmers, a director of the Swedish East India Company. He donated part of his fortune for the establishment of an “industrial school”. Chalmers was run as a private institution until 1937, when the institute became a state-owned university. In 1994, the school was incorporated as an aktiebolag under the control of the Swedish Government, the faculty and the Student Union. Chalmers is one of only three universities in Sweden which are named after a person, the other two being Karolinska Institutet and Linnaeus University.
