Using Electricity to Generate Alternative Fuel

Electrical energy generated by various methods can be difficult to store efficiently. Chemical batteries, hydraulic pumping, and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. UCLA researchers have demonstrated a method for storing electrical energy as chemical energy in higher alcohols, which can be used as liquid transportation fuels.

PDC Drill Bits Open Up Options for Geothermal Energy

Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact (PDC) bits, originally developed 30 years ago to lower the cost of geothermal drilling. Sandia National Laboratories and the U.S. Navy recently brought the technology full circle, showing how geothermal drillers might use it.

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.
