Mateo Jaramillo aims to break the 4-hour limit of lithium batteries: Insider Q&A.

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 lower costs than lithium-ion batteries. The goal is to help supply renewable energy to the electrical grid 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.
