• Between 2021 and 2024, significant projects occurred in multiple regions, including Microsoft’s hydrogen pilot in Dublin, Ireland, and Fuel Cell Energy’s power generation projects in South Korea. These activities established a global footprint for the technology.
• From 2025, the focus of major capital and deployments shifted decisively to the U.S. The $5 billion Brookfield investment fund is primarily targeting the U.S. AI data center market. Likewise, Equinix’s 100 MW expansion with Bloom Energy is concentrated on its U.S. facilities.
• This geographical concentration is reinforced by market projections. While South Korea is forecast to have a high CAGR of 15.3%, the U.S. market, with a 15.2% CAGR on a much larger base, represents the most significant growth opportunity. The U.S. market’s attractiveness is amplified by IRA tax credits like the 48 E ITC and 45 V, which improve project economics.

Technology Maturity: Fuel Cells Are Now a Bankable Prime Power Solution

Fuel cell technology has advanced from a proven backup power solution between 2021 and 2024 to a commercially bankable prime power source for mission-critical loads, a status validated by high-availability metrics and large-scale deployments by hyperscalers in 2025 and 2026.

• In the 2021-2024 timeframe, technical maturity was defined by successful long-duration tests for backup power. Microsoft’s completion of a 48-hour, 1.5 MW test of hydrogen fuel cells was a key validation point, proving the technology was a reliable alternative to diesel generators but not yet positioned for continuous 24/7 prime power.
• From 2025, the technology’s maturity is now measured by its performance as a primary power source. Bloom Energy markets its Solid Oxide Fuel Cell (SOFC) systems with “four nines” or 99.99% availability, a metric that meets or exceeds the requirements for mission-critical data center operations.
• This claim is substantiated by commercial contracts. The decision by Equinix to expand its SOFC deployment to over 100 MW for prime power, combined with Brookfield’s $5 billion commitment, confirms that both operators and financiers now consider the technology reliable and mature enough for continuous, 24/7 data center loads.

• The primary signal is the creation of dedicated infrastructure funds, like the $5 billion Brookfield partnership with Bloom Energy, designed to offer an “energy-as-a-service” model. This removes the CAPEX barrier for data center operators and allows them to secure power on timelines aligned with their business needs, not utility construction schedules.
• A second signal is the increasing use of long-term PPAs, such as those secured by Fuel Cell Energy, to provide cost certainty. With wholesale electricity prices in U.S. data center hubs increasing by as much as 267% in five years, the predictable cost of a fuel cell PPA becomes a critical strategic advantage for managing operational expenses.
• The market is clearly bifurcating. If a data center can secure a timely and affordable grid connection, it will. If not, which is an increasingly common scenario, these on-site power partnerships provide a viable, reliable, and now financially accessible alternative for 24/7 operations.
