FuelCell Energy Unveils 12.5MW Modular Power Block for Data Centers, Triples Manufacturing Capacity
March 24, 2026
FuelCell Energy, a leading US-based fuel cell developer, has launched a new modular power solution specifically engineered for the data center industry, aiming to address the sector's urgent need for rapid, scalable, and reliable power infrastructure. This move comes as the explosive growth of artificial intelligence (AI) workloads intensifies pressure on power grids and traditional energy sources, pushing data center operators to seek alternative, infrastructure-grade power solutions.
The company introduced a 12.5MW "Power Block," a configurable unit comprised of ten individual 1.25MW modules. According to FuelCell Energy, this modular design significantly reduces the site-specific engineering and permitting timelines that often delay data center projects, enabling faster power procurement. The solution is intended to provide a reliable, scalable platform for large, multi-phase data center builds, improving overall project reliability.
To meet anticipated demand from the data center market, FuelCell Energy announced a major expansion of its manufacturing facility in Torrington, Connecticut. The company plans to more than triple its production capacity, scaling from approximately 100MW to 350MW annually. This expansion is backed by a reported 275 percent increase in its business development pipeline since February 2025, which the company attributes largely to interest from data center customers.
"Customers want fast, phased deployment," said Eric Strayer, Senior Vice President and Head of Global Sales at FuelCell Energy. "Our 12.5MW Block provides an ideal balance, delivering both economies of scale and modular reliability. By implementing these solutions at our customers’ sites, we give them a reliable platform that can grow over time."
The launch solidifies the company's three-core product portfolio for data centers, which now includes 1.25MW, 2.5MW, and the new 12.5MW systems. FuelCell Energy emphasizes that its carbonate fuel cell technology is designed to deliver onsite baseload power and can operate independently of the local electrical grid. The company has already secured strategic partnerships in the sector, including a January agreement with investment firm Sustainable Development Capital to explore deploying up to 450MW of fuel cell systems for global data centers, and a prior collaboration with AI data center developer Inuverse for up to 100MW at a site in Daegu, South Korea.
The entry of FuelCell Energy with a tailored, large-scale modular product signals a growing competitive landscape for behind-the-meter power solutions in data centers. Fuel cells are increasingly viewed as a lower-carbon, dispatchable power option. The sector's current major player, Bloom Energy, has established several data center power agreements with companies like Equinix and Oracle. FuelCell Energy's strategic manufacturing expansion and focused product development highlight the intensifying race to capture a share of the data center industry's critical power infrastructure market.
