Nov. 28 (Bloomberg) — United Technologies Corp. and General Electric Co. were awarded U.S. government grants to pay for their research into alternative fuels, energy-efficient power transmission and electric vehicles, the U.S. Energy Department said.

The department’s Advanced Research Projects Agency -Energy, or ARPA-E, is awarding a total of $130 million to 66 projects. The program’s goal is to “support development of the most innovative technologies and change what’s possible for America’s energy future,” Energy Secretary Steven Chu said today in a statement.

United Technologies’ Pratt & Whitney Rocketdyne unit will receive about $3.8 million to develop a system to improve the conversion of natural gas to liquid fuels and chemicals. Also, United Technologies Research Center will receive about $2.7 million to develop a manufacturing process for electric vehicle motors that reduces rare-earth material use. GE Global Research will receive about $4.1 million to develop a new electrical power switching technology for high-voltage transmission lines.

ARPA-E’s project portfolio now totals 285, including $770 million in awards, the agency said.

Grants also were awarded for projects focused on “transformational, breakthrough technologies” in renewable power, energy storage, carbon capture and energy efficiency, according to the statement. Universities are leading 47 percent of the projects, while 29 percent are led by small businesses, 15 percent by large businesses, 7.5 percent by national labs and 1.5 percent by non-profits, the agency said.
