Form Energy and its iron batteries

Technology
United States
Started October 08, 2026

Form Energy is building iron-based batteries that can store energy for multiple days. The company is ramping up supply at its factory and signing deals for commercial projects. New solar and wind installations produce electricity more affordably than fossil fuels in most places, but their output varies based on season, time of day, and weather.…
