Mateo Jaramillo aims to extend the lifespan of lithium batteries beyond 4 hours.

Form Energy, a company founded in 2017, is building a commercial-scale factory in West Virginia to produce iron-air batteries that can store energy for up to 100 hours at a lower cost than lithium-ion batteries. The company aims to help supply the US electrical grid with renewable energy 24/7 and reduce reliance on polluting energy sources. CEO Mateo Jaramillo believes that the right kinds of energy are a core part of achieving net-zero emissions, but it will take work across all industries that touch the power sector.
