At the Department of Energy Conversion and Storage we work on sustainable energy technologies. In the energy system of the future a large part of the energy will be supplied by fluctuating sources such as solar and wind power. This makes it critically important to be able to convert and store the energy as needed.
For example, wind power may be stored by converting electricity to hydrogen which then can be stored in solid state. The key technology areas of the Department include fuel cells, electrolysis, batteries, solar cells and hydrogen storage.
