- FuelCell Energy, Inc. (FCELB) develops, manufactures, and commercializes stationary fuel cell power platforms for clean, reliable power generation. The company offers carbonate fuel cell products, including SureSource 1500, SureSource 3000, and SureSource 4000 platforms that generate electricity through electrochemical reactions using fuels such as natural gas, biogas, or hydrogen; multi-megawatt modules for utility-scale applications; and power plants for distributed generation serving commercial, industrial, utility, and government customers. Its services encompass engineering, procurement, construction, installation, commissioning, operation, and maintenance of fuel cell systems, along with SureSource OnSite Generator for backup power and SureSource Hydrogen for electrolysis-based green hydrogen production.
Founded in 1969 and headquartered in Danbury, Connecticut, FuelCell Energy operates primarily in the United States, with projects and deployments in Europe, Asia, and the Middle East, targeting segments such as utilities, data centers, wastewater treatment facilities, and carbon capture initiatives. The company focuses on ultra-clean power solutions that achieve over 60% efficiency and capture CO2 for utilization in industries like food processing and chemicals.
In recent developments, FuelCell Energy expanded its hydrogen offerings with commercial-scale electrolyzer deployments and strategic partnerships for carbon capture integration, including a 2024 alliance with ExxonMobil for CO2 utilization projects. The company secured a major U.S. Department of Energy funding award in 2025 for next-generation fuel cell modules and announced operational milestones in biogas-to-power plants across North America. These initiatives reflect FuelCell Energy's shift toward hydrogen economy enablers and scalable clean energy infrastructure amid global decarbonization efforts.
