FuelCell Energy, Inc., alongside its subsidiaries, is involved in the complete lifecycle of stationary fuel cell power plants, covering their design, manufacturing, sales, installation, continuous operation, and servicing. These systems are developed for decentralized, consistent baseload electricity generation. The company offers a range of SureSource platforms: the 1.4-megawatt (MW) SureSource 1500, the 2.8 MW SureSource 3000, the 3.7 MW SureSource 4000, the 250-kilowatt (kW) SureSource 250, and the 400 kW SureSource 400. A prominent product is the 2.3 MW SureSource Hydrogen platform, engineered to produce up to 1,200 kilograms of hydrogen daily, serving applications in multi-megawatt utilities, microgrids, distributed hydrogen, and on-site heating and cooling. Furthermore, FuelCell Energy provides the SureSource Capture system, designed to separate and concentrate carbon dioxide from the flue gases emitted by natural gas, biomass, or coal-fired power plants, as well as industrial facilities. Their technological capabilities also include solid oxide fuel cell and solid oxide electrolysis cell stack technologies. The SureSource power plants fundamentally generate clean electricity, useful thermal energy, water, and hydrogen. The company's service portfolio is extensive, featuring engineering, procurement, and construction (EPC) services, along with project financing. Post-installation support includes real-time monitoring, remote operational management, an online support system, preventative maintenance, parts and supplies, on-site and classroom training, and power plant refurbishment or recycling services. Technical support is also available for optimizing plant operation, performance, and fuel processing. FuelCell Energy serves a diverse clientele across various markets, including public utilities and independent power producers, industrial and process applications, educational and healthcare facilities, data centers and communication networks, wastewater treatment plants, government entities, microgrid developers, the food and beverage industry, and the commercial and hospitality sectors. The company's primary operational regions encompass the United States, South Korea, England, Germany, and Switzerland. Founded in 1969, FuelCell Energy, Inc. is headquartered in Danbury, Connecticut.
