Hybrid Solar System For Rooftop Hydrogen
Posted in Batteries, Electronics & Computers, Alternative Fuels, Green Design & Manufacturing, Energy Storage, Solar Power, Energy Efficiency, Renewable Energy, Energy, News, GDM on Tuesday, 16 August 2011
Instead of systems based on standard solar panels, Duke University engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen that can be stored and used on demand in fuel cells.
