AI data center boom projected to drive fuel cell market to $30 billion by 2030 as alternative power source gains adoption.
Data center developers are increasingly turning away from congested grids toward on-site fuel cells to secure reliable power. According to Rystad Energy research, the fuel cell market is projected to expand tenfold by 2030, rising from approximately $2.8 billion in 2025 to roughly $30 billion as AI computing demand drives unprecedented growth in data center construction. A contracted order book of approximately 9 gigawatts (GW)—including framework agreements with Oracle, AEP, Equinix, and Brookfield—reflects growing confidence among major operators in fuel cells as a viable long-term power source.
US grid interconnection timelines have tripled since 2015, now stretching to three to six years for large loads. Rystad Energy projects 10.4 GW of cumulative fuel cell demand from data centers between 2026 and 2030, with around 40% of projected 2030 US data center capacity likely to pursue dedicated on-site power generation rather than grid connection. Unlike conventional grid connections or large gas plants, fuel cells can be deployed rapidly and currently run on natural gas, with the capacity to transition to biogas, renewable natural gas, or hydrogen as supply matures, while producing lower on-site emissions than combustion alternatives. North America is expected to account for 91% of installed global on-site power generation capacity, benefiting from a combination of grid delays, federal tax incentives, and an established domestic supply chain.
"Power availability has become one of the defining constraints on data center growth, and operators are increasingly looking beyond the grid for solutions," said Lein Mann Bergsmark, vice president of clean tech supply chain research at Rystad Energy. "Fuel cells have moved from a niche application to a measurable part of the firm power mix. The question now is whether the supply chain can scale at the same pace as demand."
Fuel cell manufacturers are expanding capacity in response. Aggregate operational and planned manufacturing output is on track to reach 4 GW per year by 2030, up from 1.8 GW today. Solid oxide fuel cells (SOFC) have become the dominant technology for always-on data center power, accounting for approximately 53% of cumulative stationary deliveries to date. Bloom Energy holds virtually every primary-load SOFC contract in the visible order book—a concentration that presents supply chain risk should demand accelerate faster than a single manufacturer's production capacity.
This concentration extends to materials. Bloom Energy's SOFC technology depends on scandium, a critical metal used in its electrolyte chemistry. At full utilization of its planned 2 GW manufacturing expansion, Bloom's theoretical scandium requirement would approach the size of the entire global market, currently estimated at around 60 tonnes per year. This potential bottleneck is compounded by China's heavy control of the global scandium supply chain. Competitors using alternative electrolyte chemistries do not face this exposure, and a sustained supply constraint could significantly influence market share development as the sector scales. Rystad Energy projects SOFC system costs will decline 20 to 25% by 2030, though the pace will depend on manufacturers' ability to reduce costs across the full delivered system, not merely the fuel cell stack.
