FastCAP then earned a finalist spot in the 2009 MIT Clean Energy Prize (CEP), which came with some additional perks. “The value there was in the diligence effort we did on the business plan, and in the marketing effect that it had on the company,” Cooley says.

Based on their CEP business plan, that year FastCAP won a $5 million U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy grant to design ultracapacitors for its target markets in automotive and stationary storage. FastCAP also earned a 2012 DOE Geothermal Technologies Program grant to develop very high-temperature energy storage for geothermal well drilling, where temperatures far exceed what available energy-storage devices can tolerate. Still under development, these ultracapacitors have proven to perform from minus 5 C to over 250 C.
