FuelCell Energy, Inc. (NASDAQ: FCEL) is a publicly traded company that designs, manufactures and operates turnkey molten carbonate fuel cell power plants. These stationary, on-site energy solutions generate electricity and heat through an electrochemical process that combines natural gas or biogas with oxygen, producing power with lower greenhouse gas emissions than traditional fossil fuel-based generation. The company’s fuel cell technology is engineered for continuous, baseload operation and can be integrated into microgrid architectures and industrial power systems to provide reliable, around-the-clock energy.
The company’s core product suite, marketed under the SureSource brand, encompasses both power generation and integrated carbon capture or hydrogen production capabilities. In addition to selling and leasing fuel cell power plants, FuelCell Energy offers long-term service agreements that include remote monitoring, preventative maintenance and on-site support. This full-lifecycle approach positions the company as a single source for clean energy projects in sectors such as wastewater treatment, universities, data centers and commercial facilities.
Founded in 1969 and headquartered in Danbury, Connecticut, FuelCell Energy has deployed projects across North America, Europe and Asia. Its global footprint includes multiple operational sites in the United States and South Korea, where strategic partnerships and joint ventures have accelerated commercial adoption of carbonate fuel cell technology. With several decades of research and development under its belt, the company continues to refine its platform to achieve higher efficiency, lower costs and expanded use cases—paving the way for broader decarbonization of the power sector.
