Bloom Energy and Nebius announce fuel cell partnership for AI data center on-site power; BE stock jumps 13%.
Bloom Energy shares rallied 13% to $238 on Wednesday midday following an announcement that Nebius Group has selected the fuel cell maker as its behind-the-meter power partner for a flagship AI data center in Vineland, New Jersey. The move extends a strong year for Bloom Energy, with shares now up 171% year-to-date.
The announcement propelled the broader fuel cell sector higher. FuelCell Energy climbed 11% to $21.35, while the Global X Hydrogen ETF advanced 4% to $46.13. Plug Power rose 3% to $2.29, paring earlier gains after Tuesday's 10% rally on improved Q2 2026 margins and raised 2026 guidance.
Today's move represented a thematic shift from the previous session. Yesterday's gains centered on Plug Power alone, while Bloom Energy now holds the concrete data center contract at the center of investor attention.
The catalyst came during Nebius Group's Q2 2026 earnings call. The NVIDIA-backed AI cloud operator said Bloom Energy fuel cells "significantly enhance" its planned 300-megawatt Vineland facility, providing "an on-site power solution delivering reliable power quietly and ultra-low emissions," with "no significant impact" on project timelines. The Vineland site had previously faced permitting, zoning, and community opposition centered on proposed on-site gas generation.
Nebius executives stated that the Bloom partnership helps the company "unlock and expedite" sites and reiterated its goal to raise contracted power to 5 gigawatts by year-end 2026. Chief Commercial Officer Tom Blackwell and Chief Product and Infrastructure Officer Andrey Korolenko made the comments.
The Nebius win validates remarks that Bloom Energy CEO KR Sridhar made at the company's July 28 earnings report, when he said "all the major US hyperscalers and over a dozen US neoclouds, AI labs, and colocation data center operators have validated and approved our power solutions for their AI factories." Bloom Energy reported Q2 2026 revenue of $1.07 billion, up 165.5% year-over-year, with product revenue climbing 215.4%.
FuelCell Energy's advance reflected sympathy trading as investors rotated into fuel cell names amid growing recognition of AI data center power constraints and the potential for behind-the-meter distributed generation solutions. FuelCell Energy stock is up 192% year-to-date.
The Global X Hydrogen ETF's 4% gain served primarily as a pass-through, given the fund's concentration in the three U.S. names driving the move: Bloom Energy (15.5%), Plug Power (10.8%), and FuelCell Energy (7.2%) of net assets. Nevertheless, the performance indicated sector-wide participation in the AI power narrative.
NVIDIA shares rose 3% to $223.14, providing momentum as a strategic backer of Nebius. Nebius stock itself surged 26% to $243.54 following the Q2 report.
Bloom Energy carries an analyst target price of $273.51 and trades at a 284.64x forward P/E ratio with a beta of 3.832. Options positioning remains mixed, with a full-chain put/call ratio of 1.5 and hedging concentrated in longer-dated tenors.
Investors will monitor whether Bloom Energy holds above $235 through the close and whether follow-on hyperscaler and neocloud orders materialize—developments that would validate the "standard for AI onsite power" narrative. A sustained advance in HYDR would signal broader theme re-rating beyond individual stock momentum.
