Company Overview

Form Energy

Somerville, Massachusetts, United States

2017

Approximately 1,000 employees (source: formenergy.com). Revenue of $85.3 million in FY 2024 (source: martini.ai).

What They Do

Form Energy specializes in grid-scale, long-duration energy storage solutions, primarily utilizing innovative rechargeable iron-air batteries. These batteries are designed to store electricity for up to 100 hours, leveraging a unique process of reversible rusting, which involves oxidizing iron to rust while discharging and reversing the process during charging. This technology is not only cost-effective but also scalable, making it a viable option for utilities transitioning to renewable energy sources (source: wikipedia.org). The company’s products are particularly aimed at addressing the intermittency of renewable energy sources like wind and solar, providing reliable energy storage solutions that can support grid stability year-round (source: news.mit.edu). Form Energy's technology is positioned as a leader in ultra-long-duration storage, with a focus on using abundant and non-toxic materials, which sets it apart from traditional lithium-ion battery systems (source: aceventurefunds.com). The company has established contracts totaling 40 MW/4 GWh, primarily with U.S. utilities such as Xcel Energy and Georgia Power, reflecting its growing influence in the energy storage market (source: wikipedia.org).

Projects & Track Record

Form Energy has made significant strides in the commercialization of its iron-air battery technology, with notable projects including early grid-connected prototypes and ongoing large-scale deployments. The company is currently working on two major systems for Xcel Energy, each with a capacity of 10 MW/100-hour (1 GWh), located in Pueblo, Colorado, and Becker, Minnesota, contracted in January 2023 (source: wikipedia.org). Additionally, Georgia Power has ordered a 15 MW/1,500 MWh system, marking the largest single-project deal for Form Energy, which has pushed its total contracted capacity to 40 MW/4 GWh as of June 2023 (source: news.mit.edu). The company’s Weirton, West Virginia manufacturing plant, which is a $760 million investment, is set to play a crucial role in scaling production and is expected to employ approximately 750 workers (source: wikipedia.org). These projects not only highlight Form Energy's technological advancements but also its commitment to supporting the transition to renewable energy sources across the United States (source: formenergy.com).

Recent Developments

In recent years, Form Energy has made significant announcements that underscore its growth and innovation in the energy storage sector. The company unveiled its Weirton manufacturing site in December 2022, which represents a substantial $760 million investment aimed at enhancing production capabilities (source: wikipedia.org). In January 2023, Form secured contracts with Xcel Energy for two 10 MW/1 GWh systems, further solidifying its market position (source: wikipedia.org). The company also closed a significant order with Georgia Power for a 15 MW/1,500 MWh system in June 2023, which is the largest single-project deal to date, pushing its total contracted capacity to 40 MW/4 GWh (source: news.mit.edu). Additionally, Form Energy achieved UL9540A fire certification and developed a continuous high-efficiency process for converting powdered iron ore to metallic iron in 2024, marking a significant technological milestone (source: wikipedia.org). These developments reflect Form Energy's commitment to advancing energy storage solutions and its strategic focus on expanding its operational footprint in the renewable energy landscape (source: martini.ai).
