Oracle taps Bloom for 2.8 GW of fuel cells to keep datacenter binge going

The deal

It has been reported that Bloom Energy has been handed an expanded remit from Oracle to supply up to 2.8 GW of on-site fuel cell capacity for the cloud giant’s US datacenter buildout. Bloom allegedly already has an initial 1.2 GW contracted, with deployments said to be underway this year and likely to continue into 2027. The company also claims it once delivered a fully operational fuel cell site for Oracle in 55 days, versus the 90 days stipulated — speed matters when you’re racing to spin up AI compute.

Why Oracle is turning to on-site power

Why the rush? It has been reported that Oracle’s infrastructure commitments — including the headline-grabbing $300 billion deal to provide compute for OpenAI — could amount to roughly 4.5 GW of compute capacity over five years, and the US grid is straining to keep pace. Requests for new grid connections may face multi-year waits. Turbines, the usual on-site fallback, are in short supply; for example, it has been reported that xAI deployed turbines at its Colossus campus. Fuel cells present an alternative that can be installed faster, but they bring their own baggage: higher costs, reliance on expensive catalyst materials, and, if hydrogen is used, storage and safety headaches.

Questions remain

Bloom frames the expansion as a signal that distributed, on-site generation is becoming a core part of modern digital infrastructure. It has been reported that this approach reduces project risk and speeds deployment, but the economics and emissions picture are murky. The Register has asked Bloom and Oracle for details on contract value, whether the cells will run on hydrogen or natural gas, and how fuel will be delivered — by truck or pipeline — and has not yet received answers. Can fuel cells really scale to meet an AI-fueled datacenter boom, or are they a pragmatic stopgap until the grid (and turbine supply chains) catch up? Either way, this story is where raw ambition meets hard infrastructure — and that moment is always the most interesting.
