Form Energy’s breakthrough iron-air batteries solve the problem of multi-day storage of renewable energy, while creating hundreds of green jobs and speeding the global shift to clean energy.
Around the world, energy demand is rising at an unprecedented rate, driven by the rapid growth of AI data centres, electrification, and manufacturing. This surge creates a big challenge: how to deliver ever-increasing amounts of energy to billions of people without sacrificing reliability or affordability, while also cutting carbon emissions.
Clean energy sources like wind and solar are among the lowest-cost and fastest-growing forms of power, however their generation is dependent on weather conditions. This variability is a major challenge for electricity grids that need to be highly reliable.
To unleash the transformative potential of renewable energy, we need to store it when it is abundant and use it when it is not. But until recently, no commercially available, cost-effective technology existed that could provide storage for multiple days at the scale required.
This has been the missing link in building a reliable and resilient clean energy future – a gap that Form Energy is now closing.
Form Energy’s breakthrough iron-air batteries can store electricity for up to 100 hours at a fraction of the cost of lithium-based batteries, directly addressing the variability of renewables. Made using readily available iron, water, and air, and built with a modular design, they can be installed anywhere and at any size, providing reliable power around the clock.
Form Energy’s impact is already visible. Form Factory 1 in Weirton, West Virginia, is its first high-volume battery manufacturing facility and a symbol of the revival of American manufacturing industry. Built in a year, this 550,000-square-foot plant shows that advanced manufacturing can be achieved both rapidly and efficiently. The facility has already retrained a generation of workers for the clean energy transition, employing more than 400 people, and is on track to create at least 750 jobs by 2028.
Construction of Form Energy’s largest project to date is due to begin in 2027. By repurposing a former paper mill site in rural Maine, this 8,500-megawatt-hour energy storage system will have enough capacity to power around 65,000 homes for four days, helping to relieve grid congestion in the region.
As Form Energy scales, new factories and projects will create hundreds of jobs, reigniting economic opportunity in communities that have long been left behind. By 2035, their batteries are projected to reduce more than 40 million metric tons of CO₂ worldwide.
With contracts already agreed with utility and energy providers across the United States and Ireland, just as iron powers Form Energy’s batteries, America’s Rust Belt is now powering the future of clean energy.
From old industry to new innovation, Form Energy is proving climate solutions can power livelihoods and the planet.
Form Energy’s mission is to build energy storage systems that can reliably supply affordable electricity for extended periods of time, ensuring homes and businesses have power whenever they need it.
Recognition from The Earthshot Prize is a significant catalyst for us as we deliver on this mission of building energy storage for a better world. As we scale beyond the United States and enter new international markets, The Earthshot Prize will provide a key platform for new partnerships, projects, and progress.
We hope to help build the electric grid of the future; one that is clean, secure, and resilient for generations to come.
