After a six-year collaborative research at MIT, a paradigm-shifting energy storage technology was developed. It is an ultracapacitor that could offer energy densities approaching those of batteries, 20 times higher power densities than batteries, millions of full charge-discharge cycles, and projected costs lower than batteries by using only domestically abundant and eco-friendly raw materials. FastCAP SYSTEMS is the company we created to commercialize this breakthrough technology into automotive first and into the US electric grid second.
