Driven by the global wave of energy transition, hydrogen energy, as a critical pathway to achieving carbon neutrality goals, is attracting increasing attention from investors. With technological advancements and policy support, this vast market, with a potential scale of $11 trillion, is maturing at an accelerated pace. This article provides an in-depth analysis of seven representative U.S.-listed hydrogen companies to serve as an investment reference.
As global leaders in the industrial gases sector, Linde (LIN) and Air Products (APD) possess inherent advantages in the hydrogen field. Linde has not only mastered efficient hydrogen compression and safe refueling technologies but also reduces the carbon footprint of hydrogen through carbon capture. The company’s recent 100-megawatt renewable hydrogen plant project in partnership with Shell, expected to be operational by 2027, demonstrates its commitment to industrial layout.
Air Products is even more aggressive, currently operating over 100 hydrogen production plants worldwide with a daily capacity of 7 million kilograms. Its NEOM green hydrogen project in Saudi Arabia is 80% complete and expected to commence operation in 2027. The company is also advancing an $8 billion blue hydrogen project in Louisiana, a $3.3 billion blue hydrogen project in Canada, and a $360 million green hydrogen project in Arizona set to come online in 2026.
Traditional energy giant BP (BP) has positioned hydrogen energy as a key pillar of its strategy to achieve net-zero by 2050. The company plans to invest in 5-7 hydrogen and carbon capture projects globally. Its Lingen project in Germany, expected to be operational by 2027, aims to produce up to 11,000 tons of green hydrogen annually. However, BP recently canceled its HyGreen Teesside project, the UK’s first planned green hydrogen project, and exited a planned project in Australia, reflecting the challenges the industry still faces on the path to commercialization.
As a pioneer in the hydrogen fuel cell industry, Plug Power (PLUG) has deployed 72,000 fuel cell systems and operates 275 refueling stations in North America. The company is building an end-to-end green hydrogen ecosystem, with multiple green hydrogen production facilities expected to be operational before 2028. In October 2025, the company delivered its first 100-megawatt electrolyzer to Galp’s refinery in Europe, signifying international recognition of its technology.
Bloom Energy (BE) stands out with its revolutionary solid oxide technology. The company’s Bloom Electrolyzer is 15% to 45% more efficient than comparable products on the market, making it particularly suitable for decarbonizing energy-intensive industries like steel and chemicals. A recent collaboration with Oracle on powering data centers for AI workloads has opened up new growth avenues. The company has reported record revenue and profits for three consecutive quarters, demonstrating strong growth momentum.
Cummins (CMI) is deeply engaged in the hydrogen sector through its zero-emissions technology business unit, Accelera. In October 2025, the company successfully tested a prototype hydrogen-powered internal combustion engine in an intercity bus made by a Turkish-Japanese automotive joint venture, performing as well as a natural gas engine with significantly lower emissions. Simultaneously, it is supplying a 100-megawatt PEM electrolyzer for BP’s project in Germany, showcasing its strength in hydrogen equipment manufacturing.
FuelCell Energy (FCEL) focuses on distributed baseload energy solutions, with its proprietary carbonate fuel cell and solid oxide electrolyzer technologies drawing attention. The company is developing large-scale hydrogen production systems based on solid oxide electrolyzers, targeting large manufacturing plants and data centers.
Although the hydrogen industry has bright prospects, investors need to be clearly aware of the associated risks and opportunities.
Regarding opportunities: policy support is continuously increasing, with the U.S. Department of Energy aiming to reduce the cost of green hydrogen to $1 per kilogram within the next decade; market demand is clear, with urgent decarbonization needs in heavy industry, transportation, and power generation; technological progress is significant, with electrolyzer efficiency continually improving and production costs steadily declining.
Risk factors include: uncertainty in the commercialization timeline, as evidenced by the cancellation of several major projects like BP’s; most specialized hydrogen companies are not yet profitable, putting pressure on their financials; the industry is heavily influenced by policies, and geopolitical factors could alter the development pace.
For investors with different risk appetites, a differentiated strategy is recommended: conservative investors might focus on industrial gas giants like Linde and Air Products, which have stable cash flows; growth-oriented investors could consider specialized firms with leading technology like Plug Power and Bloom Energy; while the traditional energy transition representative BP offers a middle ground balancing dividends and growth.
As the global energy transition moves into deeper waters, the development pace of the hydrogen energy industry is clearly accelerating. Although challenges remain ahead, this trillion-dollar track has already opened the door of opportunity for visionary investors. When selecting specific investment targets, investors should focus on companies’ technological barriers, project execution capabilities, and financial health to identify the true long-term winners in this promising industry.
