Grid congestion and soaring AI power needs are pushing data center operators toward on-site fuel cells, with North America capturing 91% of capacity
The fuel cell market is about to have its moment. Rystad Energy projects revenues in the sector will surge from roughly $2.8 billion in 2025 to approximately $30 billion by 2030, a near-tenfold increase driven almost entirely by one thing: AI data centers need power, and the grid can’t deliver it fast enough.
The grid problem nobody can fix fast enough #
US grid interconnection timelines have tripled since 2015. What used to take a year or two now averages three to six years. On-site fuel cells, which generate electricity directly at the data center, are emerging as the preferred workaround. Rystad estimates that about 40% of projected 2030 US data center capacity may rely on dedicated on-site power solutions.
The contracted order book already totals approximately 9 GW, with a projected cumulative demand of 10.4 GW in data center fuel cells from 2026 to 2030. Companies like Oracle, AEP, Equinix, and Brookfield have signed agreements contributing to that pipeline.
North America is expected to dominate, accounting for 91% of global on-site fuel cell capacity. The reasons are straightforward: interconnection delays are worst in the US, federal tax incentives sweeten the economics, and the supply chain for fuel cell components is more developed domestically than in most regions.
Bloom Energy and the scandium problem #
For data centers that need continuous, uninterrupted power, solid oxide fuel cells, or SOFCs, are the technology of choice. They run on natural gas or hydrogen and deliver steady baseload power. Bloom Energy has emerged as the dominant player among visible SOFC contracts. But SOFCs depend on scandium, a rare earth element that most people have never heard of. China controls the majority of global scandium supply, which creates an uncomfortable dependency for an industry that’s supposed to solve energy independence problems. Competitors are already working on alternative chemistries to reduce or eliminate scandium from the equation.
Where crypto miners fit into the picture #
IREN, formerly known as Iris Energy, signed a $3.65 billion agreement with Microsoft to repurpose its mining infrastructure for AI data center use. Bitcoin miners spent years building energy-hungry facilities in remote locations with cheap power. Now AI companies are willing to pay a premium for those exact same assets.
What this means for investors #
The risk factors are worth watching closely. Scandium supply concentration in China introduces geopolitical risk that could constrain SOFC scaling. Grid modernization efforts, while slow, could eventually reduce the urgency for on-site solutions. And the fuel cell market’s projected growth assumes AI compute demand continues its current trajectory.
