Bloom Energy Corporation
HQ: 🇺🇸 United States Segment: Fuel Cell Manufacturer

Bloom Energy is a US manufacturer listed on the NYSE, known for its solid oxide fuel cell Energy Server — a modular on-site power product that runs on natural gas, biogas, hydrogen or blends. Demand has been driven by AI data-center and colocation customers buying speed to power. Second-quarter 2026 revenue was a record $1.07 billion, up 165% year on year, and the company raised full-year 2026 guidance to $3.9–4.2 billion; total backlog stood at about $20 billion, of which roughly $6 billion was product backlog. Brookfield expanded its financing framework for Bloom projects from $5 billion to $25 billion in June 2026. The Bloom Electrolyzer uses the same solid-oxide platform to make hydrogen from steam at 700–900°C, but the FY2025 10-K states that nearly all product revenue still comes from Energy Servers, and the electrolyser line was de-prioritized with a one-time $22 million expense in Q3 2025. Bloom is therefore a distributed-power business selling into data centers, with hydrogen as longer-dated optionality.

Efficiency and cost figures it publishes apply to specific products and do not generalize across PEM fuel cells as a class.

Hydrogen Stocks — Investor FAQ

This list covers the full hydrogen value chain: electrolyser manufacturers (Nel, ITM Power, Plug Power, thyssenkrupp nucera), fuel cell manufacturers (Bloom Energy, Ballard Power, FuelCell Energy), industrial gas companies with major hydrogen operations (Linde, Air Products, Air Liquide), hydrogen infrastructure and storage companies, hydrogen mobility and vehicle manufacturers (Toyota, Hyundai, Honda), and diversified industrials with significant hydrogen exposure (Cummins, thyssenkrupp, Mitsubishi Heavy, Sinopec).
This list applies the same two-part test to large and small companies: hydrogen exposure must be material enough to the investment case, and a practical public listing must be available. Toyota, Linde and Sinopec qualify because each has operating products, assets or supply activities tied directly to hydrogen, even though hydrogen is not its primary source of group revenue. The Exposure filter distinguishes these diversified companies from pure-play names and from companies where the qualifying activity is a minor part of a much larger group. Inclusion describes business exposure, not a judgement on investment quality or future returns.
Gray hydrogen is produced from fossil feedstocks without carbon capture. Blue hydrogen applies carbon capture and storage to a fossil-based process, but its lifecycle emissions depend on the capture boundary and rate, upstream methane leakage, plant energy use and storage integrity. Green hydrogen is produced by electrolysis using renewable electricity; its lifecycle emissions still depend on the electricity actually used and on the accounting boundary. These color labels are useful shorthand, but project-level emissions data are needed to compare production routes reliably.
Most pure-play electrolyser and fuel cell companies (Nel, ITM Power, Plug Power, FuelCell Energy) remained loss-making based on their latest results available in August 2026. The sector has also consolidated: Green Hydrogen Systems filed for bankruptcy in June 2025, after which thyssenkrupp nucera acquired core technology assets; Cummins announced in early 2026 that it intended to stop new commercial electrolyser activity at Accelera after recording $458 million of 2025 charges; and thyssenkrupp nucera said in August 2026 that it would not pursue in-house mass production of solid-oxide stacks. Profitability depends on equipment costs, renewable-power prices, customer demand and policy support. Industrial-gas majors are profitable at group level, but that does not establish the profitability of their low-carbon hydrogen projects.
Market capitalizations on this page are refreshed monthly from Yahoo Finance data, and the date of the snapshot is shown above the table.

The hydrogen sector contains many early-stage listed companies that are pre-revenue or in early commercial deployment, particularly in Australia (HZR, PV1), Norway (HYPRO, HPUR) and Canada (FHYD.V). Micro-cap hydrogen companies typically carry financing risk, thin trading liquidity, and technology and offtake risk that larger diversified names do not. They are included because they meet this list's inclusion criteria as listed companies with hydrogen as a primary business, not because of any view on their prospects. This list is built to stated criteria rather than being a complete register of every listed company with hydrogen exposure.

Key Terms
Full Glossary →

A device that uses electricity to split water into hydrogen and oxygen. The lifecycle emissions of the hydrogen depend mainly on the electricity source, plant operation and accounting boundary; electrolysis is not automatically low-carbon. Main technologies include alkaline, proton exchange membrane (PEM) and solid oxide (SOEC). Alkaline and PEM systems operate at lower temperatures, while SOEC can achieve high electrical efficiency when suitable high-temperature heat is available but is less commercially mature.
Hydrogen produced by electrolysis using renewable electricity. Its lifecycle emissions are not fixed: they depend on the electricity actually used and on the accounting boundary applied, so electrolysis run on dedicated renewables sits among the lowest-carbon routes available while grid-connected electrolysis can carry a materially higher footprint. Green hydrogen costs more than unabated fossil hydrogen today. The IEA's Global Hydrogen Review 2026 identifies China as the one region where renewable hydrogen could reach cost-competitiveness by 2030, and finds low-emissions hydrogen staying more costly than fossil-based hydrogen in most other parts of the world.
Hydrogen produced from natural gas via steam methane reforming (SMR), releasing CO₂ that is not captured. It is the largest single source of the world's hydrogen. Gray hydrogen and coal gasification are the two unabated fossil routes, and hydrogen that is not low-emissions still made up more than 98% of global supply in 2025, when low-emissions production came in under 1% of the total (IEA, Global Hydrogen Review 2026). Gray hydrogen is the economic benchmark green hydrogen has to beat.
Hydrogen produced from fossil feedstocks, usually natural gas, with carbon capture and storage applied to part of the process emissions. Its lifecycle emissions vary with the capture boundary and rate, energy used by the plant, upstream methane leakage and the permanence of CO2 storage. Blue hydrogen can be lower-emissions than unabated fossil hydrogen, but the label alone does not establish that a project is low-carbon.
An electrochemical device that converts a fuel and an oxidant into electricity and heat. PEM and alkaline fuel cells commonly use hydrogen directly; solid-oxide systems can also use or internally reform fuels such as natural gas or biogas. A fuel cell supplied with pure hydrogen produces water and no carbon dioxide at the point of use, but lifecycle emissions depend on fuel production and delivery. Applications include vehicles, backup power and distributed generation.
An electric vehicle in which a hydrogen fuel cell supplies electricity to the traction system, normally alongside a smaller battery that handles regenerative braking and short-term power demands. When fueled with hydrogen, the vehicle emits water at the tailpipe; lifecycle emissions depend on hydrogen production and distribution. Refuelling can be faster and onboard energy storage lighter than for some battery-electric heavy-duty applications, but the comparison varies by vehicle, route and infrastructure.
A proton exchange membrane electrolyser uses a solid polymer membrane to conduct protons. PEM systems can be compact, produce high-purity hydrogen and respond quickly across a broad operating range, which can suit variable power. They typically use scarce catalyst materials and their relative cost and operating advantage over alkaline systems depends on design, scale, duty cycle and market conditions.
An electrolyser that uses a liquid alkaline electrolyte, commonly potassium hydroxide, and established electrode and separator designs. It is a mature technology available at industrial scale and often uses less scarce catalyst material than PEM. Traditional systems were designed for steadier operation, but modern alkaline products can also operate dynamically; actual flexibility depends on the system design and balance of plant.
Ammonia made using hydrogen from renewable-powered electrolysis and nitrogen separated from air, with renewable or other low-carbon energy used across the process. It can serve as a fertiliser feedstock, chemical input, shipping fuel or hydrogen carrier. The term does not guarantee zero lifecycle emissions: results depend on electricity sourcing, construction, transport, conversion losses and any downstream use. NEOM in Saudi Arabia and Yara's renewable-hydrogen projects are prominent examples under development or operation at different scales.
A geographic cluster of hydrogen production, distribution, and end-use infrastructure designed to create economies of scale and reduce costs. Hydrogen valleys are typically supported by government policy and may include electrolysers, pipelines, refuelling stations, and industrial off-takers. Notable examples promoted by the EU's Clean Hydrogen Partnership include HEAVENN in the northern Netherlands and Green Hysland in Mallorca; Korea's Hydrogen City program and Australia's National Hydrogen Hubs follow similar concepts. (The European Hydrogen Backbone is a related but distinct pipeline-network initiative for cross-border hydrogen transport.)
The average cost per kilogram of hydrogen produced over a plant's lifetime, including capital costs, electricity, water and operations. In 2025, renewable-powered electrolysis produced hydrogen at more than USD 3 per kg to well above USD 10 per kg, with only China reaching the low end, according to the IEA's Global Hydrogen Review 2026. The same report's cost-acceptability analysis finds that without policy support, most hydrogen users could pay below USD 2 per kg and still match the incumbent production route, which is why that level is the common benchmark for cost-competitive green hydrogen.
