In a world first, scientists claim to have used sunlight, water and carbon dioxide to make ‘green’ jet fuel. A European consortium with the participation of ETH Zurich has experimentally demonstrated the first ever production of jet fuel via a thermo chemical process using concentrated solar energy. The key component of the production process of sustainable “solar kerosene” is a high temperature solar reactor developed by the group of Aldo Steinfeld, Professor of Renewable Energy Carriers at ETH Zurich. The reactor contains a porous ceramic solar absorber made of the metal oxide ceria, which enables the molecular splitting of water and CO2 in a cyclic two-step reduction-oxidation (redox) process.
