What FUELCELL ENERGY INC does
In the company’s own words
FuelCell Energy, Inc. (Nasdaq: FCEL) is a clean energy technology company and stationary fuel cell manufacturer headquartered in Danbury, Connecticut. The company's website is www.fuelcellenergy.com. Founded in 1969, FuelCell Energy has accumulated 22 years of operating experience in the fuel cell industry and manufactures proprietary molten carbonate fuel cell systems that deliver large-scale, continuous clean power and advanced emissions management capabilities.
The company's core business centers on designing, developing, manufacturing, installing, operating, and maintaining fuel cell power plants. FuelCell Energy's carbonate fuel cell platform operates at approximately 1000 degrees Fahrenheit and generates electricity electrochemically rather than through combustion, resulting in ultra-low emissions and high electrical efficiency of up to 50 percent. The systems are sold in modular 1.25 megawatt power blocks that can be scaled to meet hundreds of megawatts of demand, achieving power density of up to 33 megawatts per acre. The fuel cell systems are fuel-flexible, capable of running on natural gas, biogas, renewable natural gas, or hydrogen-hydrocarbon blends.
FuelCell Energy operates across multiple revenue streams including product sales, service agreements, generation revenue from retained projects, and advanced technologies contracts. The company targets distributed generation markets including utilities, independent power producers, data centers, wastewater treatment facilities, and commercial applications. Geographic markets include the United States and Canada, the European Union and United Kingdom, and priority Asian markets including South Korea, Singapore, Malaysia, and Thailand.
The company has proven utility-scale projects operating at 10 megawatt, 20 megawatt, and 58.8 megawatt capacities, each with more than seven years of continuous runtime. Beyond its commercially available carbonate platform, FuelCell Energy engages in research and development of solid oxide electrolysis technology for distributed hydrogen production. The company's carbonate fuel cell systems provide baseload power, carbon capture and recovery capabilities, combined heat and power functionality, and thermal energy applications for absorption chilling and heating. Competitive advantages include 22 years of operational experience, a portfolio of over 55 patents covering solid oxide technology, full in-house manufacturing control, and proven ability to deliver reliable power in diverse applications.
