First Step in Converting Solar Energy Using Artificial Leaf

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team, headed by Leiden University professor Huub de Groot, modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria.

Feather Fibers Fluff Up Hydrogen Storage Capacity

Scientists have developed a new hydrogen storage method - carbonized chicken feather fibers - that can hold vast amounts of hydrogen, and do it at a far lower cost than other hydrogen storage systems. The research could help overcome some of the hurdles to using hydrogen fuel in cars, trucks, and other machinery.

Sensing Method Checks Refrigerant Levels, Saves Energy

A new “virtual refrigerant charge sensor" saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime. Engineers at Purdue University developed the sensing technique, which is particularly practical for automotive air conditioners.

A Step Toward Producing Plastic from Biomass

Researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. This procedure, if it can be effectively industrialized, could allow many of today’s petrochemical products, including plastics, to instead be made from biomass.

World's First Full-Scale Floating Windmill to Undergo Testing

News of the world's first full-scale floating windmill being built spread over a year ago. Now, the Hywind has reached its final destination, where it will face rigorous testing. The Hywind concept combines known technologies in a novel way: a 2.3 MW wind turbine is attached to the top of a Spar-buoy, a solution familiar from production platforms and offshore loading buoys. It captures the wind's energy where the wind is strongest – out at sea.
