Siemens Energy is a German industrial giant specializing in power generation, transmission, and energy transition technologies. The company is actively expanding into hydrogen production, including electrolyzer systems, Power-to-X solutions, and large-scale green hydrogen projects across Europe and Asia. The company partners with global automotive and energy firms to deploy fuel cell solutions at scale, supporting the transition to zero-emission mobility and industrial power applications. FuelCell Energy is a global leader in delivering distributed baseload energy (energy produced on-site to provide steady power to a building).

ITM Power is scaling electrolyzer production through its partnership with Linde and securing orders for Europe’s largest green hydrogen projects. Air Products’ extensive global infrastructure, established partnerships, and technological leadership provide a significant competitive edge in the hydrogen sector. The company’s ability to execute large-scale projects and secure long-term contracts positions it as a reliable partner in the transition to a low-carbon economy. Linde’s extensive green hydrogen stocks global infrastructure, established partnerships, and technological leadership provide a significant competitive edge in the hydrogen sector.

Air Liquide’s hydrogen production and distribution technologies are well-established, with decades of operational experience. The company’s focus on scaling electrolyzer capacity and integrating renewable energy sources further enhances the maturity and reliability of its technology portfolio. 4/5 – Air Products’ hydrogen projects are highly dependent on government incentives and policy support, particularly in the U.S. and Europe.

This is timely, as governments roll out subsidies (like the U.S. hydrogen production credit) and large projects move from planning to procurement. Nel has already secured contracts, from decarbonizing steel production in Sweden to equipping hydrogen fueling stations for heavy trucks in California. NuScale Power, Plug Power, and CF Industries are the three Hydrogen stocks to watch today, according to MarketBeat’s stock screener tool. These companies had the highest dollar trading volume of any Hydrogen stocks within the last several days. Investors should focus on companies with clear hydrogen capacity targets and policy-backed projects to reduce execution risk. Diversifying across electrolyzers, fuel cells, and industrial gas leaders balances growth and stability.

Plug Power

These challenges include the high cost of production, the lack of infrastructure, and the need for government support. The green hydrogen market will experience significant expansion during the next five years because of technological advancements and decreasing production costs and supportive clean energy policies. Fusion Fuel’s modular approach allows for flexible, localized hydrogen production with lower infrastructure costs.

Who is the largest hydrogen producer in the United States?

If traders sour on the unkept promises of PLUG and FCEL, Bloom might be next in line for mega volume. As countries worldwide revamp their energy infrastructure, APD might be in position to capitalize. While NuScale Power currently has a Reduce rating among analysts, top-rated analysts believe these five stocks are better buys.

Topsoe’s catalysts and electrolysis technologies are mature and widely licensed, with decades of operational experience. The company continues to innovate in electrolysis efficiency, ammonia synthesis, and carbon-neutral hydrogen pathways. 4/5 – Growth is closely tied to U.S. and state-level incentives for hydrogen and clean energy. Nel ASA benefits from EU hydrogen incentives, Norwegian government grants, and public-private funding schemes for hydrogen infrastructure projects. Engie is actively expanding its hydrogen portfolio through joint ventures and partnerships with Linde, ITM Power, and local governments. Recent U.S. IRA grants and EU hydrogen auctions support the construction of multiple renewable hydrogen hubs.

• Plug Power is actively expanding its global hydrogen network, including new production facilities and partnerships for large-scale green hydrogen.
• It has 20 gigawatts of power produced by 5,300 power plants in the U.S., Canada, Latin America, and Europe.
• FuelCell Energy is proving its solutions in real projects (like Toyota’s and Exxon’s), and if these successes scale up, the company could move from niche to indispensable in a carbon-constrained world.
• Major companies building production facilities, transportation systems, and storage networks.
• FuelCell Energy is a U.S.-based developer of stationary fuel cells and integrated hydrogen solutions.
• These are the green hydrogen stocks with the most upside—and risk—with direct leverage to capacity additions, technology learning rates, and final investment decisions.

Which companies are pure-play green hydrogen producers?

• Bloom reported its second-quarter numbers in late July, delivering its third straight quarter of record revenue and profits.
• The company’s ability to execute large-scale projects and secure long-term contracts positions it as a reliable partner in the transition to a low-carbon economy.
• The company also participates in international hydrogen initiatives promoting low-carbon technologies.
• Linde’s hydrogen production and distribution technologies are well-established, with decades of operational experience.

Ballard makes fuel cells that can power buses, commercial trucks, trains, ships, passenger cars and forklifts, making it a similarly attractive play on decarbonized transportation, compared with Plug Power. Geographic exposure in the U.S., Europe, and Asia captures global market opportunities. Strategic portfolio allocation enables participation in the accelerating green hydrogen economy from 2025–2030. Market growth and integration require the expansion of hydrogen transport systems along with storage facilities and fueling stations. The development of large-scale infrastructure advances through industrial efforts such as Saudi Arabia’s NEOM green hydrogen complex and the European Union’s Hydrogen Strategy. Green hydrogen production needs to become less expensive in order to achieve widespread market adoption.
