Nanotrees Turn Sunshine into Hydrogen Fuel

University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy and harvest it for hydrogen fuel generation. Nanowires, which are made from abundant natural materials like silicon and zinc oxide, offer a cheap way to deliver hydrogen fuel on a mass scale.

Deploying U.S. Offshore Wind Projects

Offshore wind is an enormous potential resource for the United States - with strong, consistent winds located in the Atlantic, Pacific, the Great Lakes, and the Gulf of Mexico. As part of a planned six-year $180 million initiative, an initial $20 million will be available from the DOE this year as the first step in supporting up to four innovative offshore wind energy installations across the U.S.

Identifying Effective Carbon Capture Technologies

Approximately 75 percent of electricity used in the U.S. is produced by coal-burning power plants that expel carbon dioxide into the atmosphere. Berkeley Lab researchers are searching for porous materials to filter out the CO2 before it reaches the atmosphere, but identifying these materials is easier said than done.
