ARPA-E: Leaping Ahead in Energy Storage Innovation
The Advanced Research Projects Agency – Energy (ARPA-E) works at the heart of high-risk energy innovations. Modeled after the Defense Advanced Research Projects Agency (DARPA), ARPA-E was established in 2007 to promote and fund energy technology research and development. With an annual budget in the neighborhood of $400 million, this agency supports the development of technologies that result in reductions in imported fuels and energy-related greenhouse-gas emissions, while improving energy efficiency across all sectors.
On Thursday, the agency’s director Arun Majumdar announced that a new technology will be tested on the nation’s electric grid. It is believed that the first company to be tested in this grid environment will be an advanced compressed air energy storage (CAES) technology. This technology could efficiently store energy in the form of compressed air, which can be stored and later released – creating a type of air battery that can be used on the gigawatt (power plant) scale.
