Hybrid Solar System For Rooftop Hydrogen

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.

Making Durable Synthetic Catalysts for Energy Storage

Pacific Northwest National Laboratory (PNNL) researchers have used a common protein to guide the design of a material that can make hydrogen gas. The synthetic material works ten times faster than the original protein found in water-dwelling microbes - clocking in at 100,000 molecules of hydrogen gas every second.
