ARPA-e Programs


ARPA-E programs explore creative “outside-the-box” technologies that promise genuine transformation in the ways we generate, store and utilize energy. Unlike conventional DOE research, ARPA-E funds concepts that industry alone cannot support, but whose success would dramatically benefit the nation. Its high risk, high reward programs aim to substantially reduce foreign energy imports; cut energy-related greenhouse gas emissions; and improve efficiency across the energy spectrum.

GENI will fund innovative control software and high-voltage hardware than can reliably control the electric grid, specifically cost-optimizing sporadic energy sources and resiliently control power flow in real-time.

Power lines over solar panel


Solar ADEPT will focus on integrating advanced power electronics into solar panelsand solar farms to extract and deliver energy more efficiently.



Better batteries will encourage public adoption of electricvehicles and shift transportation energy reliance from oil to the domestically-powered U.S. electric grid.

IMPACCT aims to revolutionize technologies that prevent carbon dioxide produced by coal-fired power plants from entering the atmosphere and contributing to global warming.

Electrical fuse


GRIDS explores new technologies that enable widespread use of cost-effective grid-scale energy storage and balance the short-duration variability in renewable generation.



ADEPT explores materials for key advances in soft magnetics, high-voltage switches, and reliable, high-density charge storage that will reduce energy costs and consumption.

Fuel pumps


ARPA-E seeks to use microorganisms to harness energy and convert carbon dioxide into liquid fuels. Theoretically, this could be10 times more efficient than current approaches.
