Energy Storage and Carbon Capture

The aim of the group is to develop cost-competitive technologies for electricity and thermal energy storage. The work ranges from the development of the storage technologies to their integration into the wider energy system.

Due to the increase in intermittent renewable energy in the electricity grid, energy storage systems are necessary to balance the mismatch between energy supply and demand and to enable the substitution of fossil fuels. While energy storage has been employed in the form of ice storage for millennia, the widespread deployment of intermittent renewable energy requires a concerted effort in the research and deployment of energy storage technologies.
