FastCAP Systems

FastCAP is an innovation driven company with a straightforward vision - to make a big impact in energy. In 2010, after six years of collaborative research at MIT by FastCAP's co-founders, FastCAP began work under a multi-million dollar grant from the DOE ARPA-E to develop its novel ultracapacitor technology for electrified drivetrain vehicles. FastCAP was honored to receive another grant in 2011 from the DOE Geothermal Technologies Program to develop a cutting edge power system for geothermal exploration. By the conclusion of its ARPA-E program in 2014, FastCAP had achieved five validated world performance records related to the power and energy density of its cells. FastCAP has gone on to achieve additional validated world records related to its high temperature ultracapacitor technology, including the highest operating temperature. These breakthrough performance characteristics have laid the foundation for FastCAP's unique product solutions in a wide variety of applications, from vehicles to energy and space exploration.
