The sun is a clean and inexhaustible source of energy, with the potential to provide a sustainable answer to all future energy supply demands. There's just one outstanding problem: the sun doesn't always shine and its energy is hard to store. For the first time, researchers at the Paul Scherrer Institute PSI and the ETH Zurich have unveiled a chemical process that uses the sun's thermal energy to convert carbon dioxide and water directly into high-energy fuels: a procedure developed on the basis of a new material combination of cerium oxide and rhodium. This discovery marks a significant step towards the chemical storage of solar energy. The researchers published their findings in the research journal Energy and Environmental Science ._ Paul Scherrer Institute (PSI) by Uta DeffkeImage may be NSFW.
