GEM

Vision: Our Group performs R & D on fuel cells and electrolysis, concentrating on solid oxide technology (600-800°C) to convert hydrocarbons (natural gas, biofuels) into electricity and heat (gas-to-cogeneration) and convert excess electricity and waste heat into fuel (power-to-gas).

Transforming concentrated solar light, heat and water into hydrogen

— Researchers at the Laboratory of Renewable Energy Science and Engineering (LRESE) and the Group of Energy Materials (GEM), at EPFL’s School of Engineering, have demonstrated a high-temperature electrolysis reactor transforming concentrated solar light and water into hydrogen. By using high temperatures (> 700°C), the reactor requires no rare and expensive materials for the electrochemical reaction. This integrated approach has the potential to reach solar-to-fuel efficiencies larger than that of conventional non-concentrated, solar-driven electrolysis approaches.

Boosting biogas conversion with longer-lasting catalysts

— SUMMER SERIES – Master’s project (9). For his Master’s project, Yosua Hanria assessed the performance and lifespan of catalysts used to convert biogas into heat and electricity. His research will support the development of new, more efficient solid oxide fuel cells.

LAMD and the SCI STI JVH Group granted by a Bridge Discovery Grant

— Prof. Jürg Schiffmann (LAMD) and Dr. Jan van Herle (JVH Group) were awarded with a highly selective Bridge Discovery grant for the project "Clean highest efficiency hybrid power generation". This 4-year project aims at experimentally validating a power generation system aimed towards decentralized building scale power supply, based on a micro gas turbine driven by solid oxide fuel cell exhaust heat (~800°C).
