Bloom Energy

Market position

Bloom describes itself as a global leader in onsite power solutions and reports about 1.4 GW of Energy Server systems installed at more than 1,000 locations across nine countries by 2025. Its 2024 agreement with American Electric Power for up to 1 GW of fuel cells was characterized as the largest fuel cell agreement to date, and its SK Eternix project in South Korea as the largest fuel cell installation in history.

Bloom positions its platform on combustion-free electricity generation with virtually zero local pollutants, up to 99.999% availability through built-in modular redundancy, deployment in as little as 90 days, modular scalability from 325 kW blocks to hundreds of megawatts, a compact footprint, quiet operation, minimal water use, and fuel flexibility across natural gas, biogas and hydrogen. Its fuel cells also produce a concentrated CO2 stream that the company presents as enabling energy-efficient carbon capture.

Technology

Proprietary solid oxide fuel cell technology derived from a CO2-to-oxygen electrolyzer developed for NASA Mars missions. Cells are assembled into stacks, modules and full Energy Server platforms built from 325 kW blocks; the platform is fuel-flexible across natural gas, biogas and hydrogen and operates without combustion. Bloom also produces solid oxide electrolyzers, with its Delaware-built commercial electrolyzer reported to produce 20-25% more hydrogen per MW than PEM or alkaline electrolyzers. The company holds more than 1,000 patents globally.

Go-to-market

Direct enterprise sales into industry verticals, supported by case studies and customer references, combined with utility partnerships (American Electric Power), hyperscaler and OEM partnerships (Oracle Cloud Infrastructure, MiTAC, Quanta Computer, Equinix), international joint projects (SoftBank in Japan, SK Eternix in South Korea), and financing partnerships with infrastructure investors such as Brookfield. Bloom also uses thought-leadership content such as its Data Center Power Report.

Fortune 100 enterprises and large institutions across data centers, manufacturing, oil and gas, healthcare, biotech and pharma, education, utilities, retail, and tech/media/telecom. Named customers and references include Oracle Cloud Infrastructure, Intel, Conagra, FedEx, Sutter Health, Caltech, Google, Walmart, Coca-Cola, Bank of America, Equinix, The Home Depot, Stop & Shop, JSR Micro, Owens Corning and SoftBank.

Geography

Headquartered in San Jose, California, with U.S. manufacturing in Newark, Delaware and a multi-gigawatt facility in Fremont, California. The company serves customers worldwide, with installations at more than 1,000 locations across nine countries, including projects in Japan and South Korea.

History

Founded in 2001 as Ion America and renamed Bloom Energy in 2006, the company shipped its first 5 kW field trial unit to the University of Tennessee, Chattanooga in 2006 and its first 100 kW ES-5000 commercial Energy Servers to Google in July 2008. It operated in stealth for about eight years before a public launch in February 2010, with early deployments at Google, Walmart, Coca-Cola, FedEx and Bank of America. Bloom completed its first microgrid at Owens Corning in 2011 and began selling electricity rather than only hardware that year; it broke ground on the Delaware Manufacturing Center in 2012 and opened the Newark, Delaware factory in April 2012. International expansion began in 2013 with a first project in Japan alongside SoftBank, followed by a community microgrid in Hartford, Connecticut in 2016. Bloom listed on the NYSE under the ticker BE in 2018 and moved its headquarters from Sunnyvale to San Jose that year. Its Delaware factory began high-volume commercial electrolyzer manufacturing in November 2022, and the Fremont gigawatt facility opened in 2022. Recent years brought large-scale agreements with American Electric Power, SK Eternix, Quanta Computer, Equinix and Oracle Cloud Infrastructure.

Risks & controversies

Bloom was unprofitable through its first 19 years of operation, in some years losing more than $200 million, and stated at its 2018 IPO that it did not expect to be profitable in the near future; it also disclosed a legal settlement with some investors at that time. It recorded a net loss of $87 million in 2025. The business has been sensitive to government incentives: a federal fuel cell subsidy expired in 2016 and the California Self-Generation Incentive Program was discontinued the following year as the state shifted subsidies toward batteries, with the federal subsidy restored in 2018. Shares had lost nearly 50% of their value by 2020.
