U.S. Energy Department Announces First-of-its-Kind, High-Temperature, Downhole Rechargeable Energy Storage Device (DOE/EERE)
The U.S. Energy Department today announced commercialization of a rechargeable energy storage device capable of operating in the extreme temperatures necessary for geothermal energy production.
Industry partner FastCAP Systems successfully demonstrated an ultracapacitor that is fully operational in 200°C conditions, extending the upper limit of high-temperature energy storage and electronics, and engineering a flexible system that could reduce cost and risks of geothermal drilling.
A $2.2 million Energy Department investment, coupled with $5.5 million in private investment funds, will support expansion of production capabilities in a newly expanded space in Boston's Innovation District, a thriving center for manufacturing and technology.
