Hydrogen and other fuels are expected to play a key role as energy carrier for the transport sector and as energy buffer for the integration of large amounts of renewable energy into the grid. Therefore the development of carbon lean technologies producing hydrogen at reasonable price from...

Solar-powered thermo-chemical cycles are capable to directly transfer concentrated sunlight into chemical energy by a series of chemical and electro-chemical reactions, and of these cycles, thehybrid-sulphur (HyS) cycle was identified as the most promising one. The project focus was on...

To address the challenges of solar energy capture and storage in the form of a chemical fuel, we will develop a hybrid photoelectrochemical-photovoltaic (PEC-PV) tandem device for light-driven water splitting. This concept is based on a visible light-absorbing metal oxide photoelectrode, which...
