An international group of researchers has succeeded in producing the world's first jet fuel from sunlight, water and carbon dioxide in the SOLAR-JET (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable JET fuel) project. Unlike conventional kerosene, produced using petroleum, the alternative fuel is based on resources that are available in almost unlimited quantities and could therefore make a significant contribution to sustainability and supply security within air transport. The project partners include the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), ETH Zürich, Bauhaus Luftfahrt, Shell Global Solutions and the consulting firm ARTTIC.
