Clean, virtually non-polluting fuel cells replace previously planned combustion-based technology at first US deployment
328 MW of installed capacity planned to be operational this year
Long-term partnership with Bloom supports Nebius's US build-out, with potential for global expansion

Nebius (NASDAQ:NBIS), the AI cloud company, and Bloom Energy today announced an agreement to deploy Bloom's fuel cell technology to help power Nebius's AI infrastructure build-out. Nebius selected Bloom for its fast time to power, clean, virtually non-polluting technology, and its ability to support the extreme performance demands of AI workloads.

Bloom's fuel cell systems will provide behind-the-meter electricity for Nebius and help meet demand for the compute capacity underpinning its full-stack AI cloud platform. The modular fuel cells can be sited and commissioned on accelerated timelines, reducing dependence on new transmission build and shortening time-to-power for Nebius and its end customers. As a result, the first project with 328 MW of installed capacity is expected to be operational this year, eliminating the need for gas turbines at the site.

Bloom fuel cells generate electricity without combustion, making them highly efficient with low emissions and minimal water use, supporting Nebius's strategy to scale AI infrastructure with a lower environmental footprint. Fuel-cell systems typically face a lighter permitting burden than combustion-based generation, further accelerating the timeline from site selection to operational capacity.

"Power remains a key constraint for AI infrastructure build-outs," said Andrey Korolenko, Chief Product and Infrastructure Officer at Nebius. "We chose Bloom because their fuel cells solve that directly: Clean power with virtually no pollutants is deployed onsite, on the timelines our customers need, with the availability AI workloads require. We expect to put this technology to work alongside our infrastructure as we continue to scale our capacity."

"AI workloads demand power infrastructure that matches the performance of the cloud platforms they run on," said Aman Joshi, Chief Commercial Officer at Bloom. "Our partnership with AI cloud leader Nebius brings together Bloom's clean fuel cell technology and AI-native infrastructure, and helps deliver a community-friendly, high-performance solution at scale."

Nebius is establishing one of the largest footprints of purpose-built AI compute capacity globally, with sites across the United States and the EMEA region.

The long-term partnership with Bloom supports Nebius's US build-out with potential for global expansion as Nebius scales.
