Organizational Activities

ETH Zurich (Swiss Federal Institute of Technology Zurich, is one of the leading international universities for technology and the natural sciences. It is well-known for its excellent education, ground-breaking fundamental research and for putting its new findings directly into practice. Founded in 1855, ETH Zurich today has some 18,000 students from over 100 different countries, 3,800 of whom are doctoral students. It offers researchers an inspiring working environment and its students a comprehensive education. 21 Nobel Laureates have studied, taught or conducted research at ETH Zurich, underlining the excellent reputation of the institute. Within ETH Zurich, The Professorship of Renewable Energy Carriers conducts research aimed at the advancement of the thermal and chemical engineering sciences applied to renewable energy technologies. The research focus comprises high-temperature heat/mass transfer phenomena and multi-phase reacting flows, with applications in solar power, fuels, and materials production, decarbonization and metallurgical processes, CO2 capture and recycling, energy storage and sustainable energy systems.

Role in SOLAR-JET Project

The Professorship of Renewable Energy Carriers at ETH Zurich is a world leader in solar thermochemical fuel engineering. It specializes in using concentrated solar energy as the source of high-temperature process heat to drive highly endothermic reactions and generate solar fuels, e.g. H2 and CO from H2O and CO2. The primary contribution to the SOLAR-JET project is in the development of the solar reactor technology for the H2O/CO2-splitting thermochemical cycle via ceria redox reactions. ETH Zurich has expertise in developing and refining technologies geared towards the production of solar fuels and has unique experimental research facilities for controlled experimentation under high-flux solar radiation.
