Major technology companies in the United States are increasingly turning to fuel cell developers and providers to supply electricity for data centers and AI computing facilities, drawn by the technology's cleaner profile and faster deployment timelines compared to conventional gas-fired power plants.

Fuel cells generate electricity through the direct conversion of chemical energy into electrical energy without combustion. The technology is compatible with a range of fuels, including hydrogen, natural gas, and biogas. As surging power demand from the AI boom places growing strain on electrical grids, fuel cells offer a path to distributed power generation capable of serving remote locations— sidestepping the lengthy permitting and construction timelines associated with gas-fired power plants. The challenge is acute because AI model training and inference workloads are far more power-intensive than traditional cloud computing, and grid interconnection queues across many U.S. markets now routinely stretch several years.

Fuel cell technology's reduced environmental footprint—characterized by lower emissions and decreased water consumption—aligns with Big Tech's commitments to lower carbon intensity while expanding computational capacity. Companies including Google, Microsoft, Amazon, and Meta have all set public targets for carbon-free or net-zero operations, adding urgency to the search for dispatchable clean power that can run around the clock.

Goldman Sachs Research, in a report issued late last year, said fuel cells could enable companies to establish new sources of low-carbon electricity relatively quickly. Power demand growth from data centers could represent energy's "most important incremental use since the industrial revolution," said Michele Della Vigna, head of Natural Resources Research in EMEA at Goldman Sachs Research.

The investment bank estimates that fuel cells could ultimately supply 6–15% of incremental data center power demand, equivalent to 25–50% of total behind-the-meter power generation supply. This translates to approximately 8–20 GW of fuel cell capacity needed to supply electricity by 2030.

According to Goldman Sachs, fuel cell systems hold several advantages over gas turbines for power generation. Modular fuel cell systems can be deployed in under a year, whereas turbine lead times have stretched beyond five years. Fuel cells are 10–30% more efficient than gas turbines, produce significantly less noise, and generate no NOx or CO emissions. They also offer greater load versatility, making them better suited to support the continuous baseload requirements of data centers.

Current deployment remains constrained by limited manufacturing capacity, Goldman Sachs noted, though this could shift with anticipated manufacturing expansion in the United States and Asia. Federal incentives under the Inflation Reduction Act, including tax credits for clean energy manufacturing and hydrogen production, are expected to further improve the economics of domestic fuel cell supply chains.

Several major technology companies have already moved to integrate fuel cell systems into their data and AI center operations. The technology competes alongside other behind-the-meter options—including small modular nuclear reactors and onsite renewables paired with battery storage—as operators seek to diversify their power portfolios.

Bloom Energy is deploying its fuel cell technology at select Oracle Cloud Infrastructure (OCI) data centers in the United States. Bloom Energy also maintains a long-standing partnership with Equinix, supplying fuel cells that supplement grid power at 19 Equinix IBX data centers across six states.

"As the demand for power increases, we anticipate innovation in alternative energy technologies increasingly playing a key role in the availability of power going forward," said David Rinard, Vice President of Energy Operations at Equinix.

Equinix, which has utilized Bloom Energy's fuel cell technology for a decade, reports that the systems have enabled the company to avoid 285,000 tons of CO2e emissions and 382 billion gallons of embedded water use. The digital infrastructure company has also secured agreements with next-generation nuclear providers Oklo, Radiant, ULC-Energy, and Stellaria to further expand its alternative energy supply for data centers.

"With innovation and investments in a wide variety of power generation technologies, data centers have the potential to shift from being energy consumers to being grid assets," said Christopher Wellise, VP of Sustainability at Equinix.

FuelCell Energy, another developer in the sector, announced a strategic agreement with Fit Energy for up to 380 megawatts (MW) of on-site power for data centers using its utility-scale fuel cell technology.

"In effect, we are focused on extending the grid to the data center, enabling customers to accelerate time-to-power, reducing dependence on constrained transmission infrastructure, removing permitting friction, and supporting the growing energy demands of AI-driven compute environments with proven, scalable technology," said Jason Few, President and CEO of FuelCell Energy, in an earnings release issued in June.
