Form Energy raises $750M for 100-hour grid batteries amid AI demand

Form Energy has successfully raised $750 million to accelerate the manufacturing of its innovative 100-hour iron-air batteries. These batteries are designed to provide long-duration energy storage, which is critical for grid stability and for meeting the escalating energy demands fueled by the growth of AI data centers. Form Energy's technology presents a more cost-effective solution compared to traditional lithium-based batteries and benefits from a domestic supply chain. The substantial funding will enable the company to expand its production capacity and further develop its grid-scale energy storage solutions.

In a related development, Reservoir has secured $8 million in seed funding. The company is focused on developing and deploying smart water heaters that possess energy storage capabilities. These smart water heaters are intended to help reduce energy costs for households and contribute to the overall stability of the electrical grid. Reservoir's objective is to enhance the intelligence and efficiency of water heating systems, turning them into active participants in energy management rather than passive consumers.

Both Form Energy and Reservoir are addressing the growing need for energy storage solutions, albeit through different technological approaches and scales. Form Energy targets grid-level storage with its large-capacity iron-air batteries, while Reservoir focuses on distributed energy storage at the household level through modified water heaters. The common goal is to create more resilient and efficient energy systems capable of handling increased demand and providing grid services.
