Form Energy develops and commercializes a low-cost battery system that can store wind and solar energy for a long duration. It aims to make batteries that can dispatch energy for days, expanding the ability to supply wind and solar power to the grid. The company's technology transforms the electric grid by making renewable energy dispatchable year-round, as well as extending transmission capacity without building new wires, and replacing the need for conventional thermal generation. Its core technology was invented at MIT and is supported by investors which include Breakthrough Energy Ventures, MIT’s The Engine, Macquarie Capital, Eni Next, Capricorn Investment Group, and Prelude Ventures. Their team members are active learners who like working on tough technology problems that can only be solved with a combination of scientific innovation and hard work.

Founded by Mateo Jaramillo (Co-founder, CEO), Yet-Ming Chiang (Co-founder, Chief Science Officer), Ted Wiley (Co-founder, President & COO), William Woodford (Co-founder, CTO), Marco Ferrara (Co-founder, Chief Digital Officer)
