Nebius and Bloom Energy said on May 20, 2026, that they have struck an agreement to deploy Bloom’s fuel cell technology to support Nebius’s artificial intelligence infrastructure build-out. The first project under the deal is expected to carry 328 MW of installed capacity and to be operational this year.
The companies said the system will provide behind-the-meter electricity for Nebius, helping shorten time-to-power and reduce reliance on new transmission build. Bloom’s modular fuel cells can be sited and commissioned on accelerated timelines, and the first project will eliminate the need for reciprocating engines at the site.
The announcement lands at a time when access to power has become one of the most immediate bottlenecks for AI developers. Nebius, which is listed on Nasdaq under NBIS and is headquartered in Amsterdam, said it is building one of the largest footprints of purpose-built AI compute capacity globally. The company has sites across the United States and the EMEA region, and it said the long-term partnership with Bloom supports its U.S. build-out with potential for global expansion as it scales.
Andrey Korolenko, speaking for Nebius, said power remains a key constraint for AI infrastructure build-outs. He said Bloom was chosen because its fuel cells solve that directly, with clean power and virtually no pollutants deployed onsite on the timelines customers need and with the availability AI workloads require. He added that Nebius expects to put the technology to work alongside its infrastructure as it continues to scale capacity.
Bloom said its systems generate electricity without combustion and have low emissions and minimal water use. Fuel-cell systems also typically face a lighter permitting burden than combustion-based generation, a point that could matter as data-center operators search for faster ways to bring new compute online.
Aman Joshi said AI workloads demand power infrastructure that matches the performance of the cloud platforms they run on. He said the partnership with Nebius brings together Bloom’s clean fuel cell technology and AI-native infrastructure, and helps deliver a community-friendly, high-performance solution at scale.
Bloom, headquartered in Silicon Valley, serves Fortune 500 customers around the world and counts data centers, semiconductor manufacturing, large utilities and other commercial and industrial sectors among its customers. The company employs more than 2,000 people worldwide and manufactures its systems in the United States.
For Nebius, the deal is another sign that AI infrastructure is moving toward a model where power has to be solved in the same breath as chips, servers and networking. For Bloom, it places its onsite generation technology directly in the path of one of the fastest-growing demand centers in the market.
