Hydrogen Stocks: 9 Biggest Companies
Hydrogen stocks are benefiting from cleantech sector momentum as the world moves closer to a green energy future.
The most abundant element on Earth, hydrogen is a colorless gas. It can be produced in liquid form and burned to generate electricity, or combined with oxygen atoms in fuel cells. In this way, hydrogen — which produces no carbon emissions — can replace fossil fuels in household heating, transportation and industrial processes such as steel manufacturing.
Rising demand for carbon-free energy sources alongside significant new government policies are driving growth in the hydrogen market. Grand View Research projects that the global hydrogen-generation market will grow at a compound annual growth rate of 9.3 percent from 2024 to 2030, reaching US$317.39 billion by the end of the forecast period.
It’s worth noting that the downside to hydrogen as a clean energy source is that 99 percent of the hydrogen fuel currently in production is derived from power generated by coal or gas. To combat this problem, some companies are pursuing green hydrogen, which is produced by splitting hydrogen atoms from oxygen using electrolyzers powered by renewable energy.
The hydrogen stocks on this list are focused on a diverse range of sectors in the hydrogen space, including: low-carbon hydrogen gas production, green hydrogen technology and production, hydrogen fuel cell companies, and hydrogen distribution and storage.
US hydrogen stocks
The US hydrogen market is well established, accounting for “more than half the world’s fuel cell vehicles, 25,000 fuel cell material handling vehicles, more than 8,000 small scale fuel systems in 40 states, and more than 550 MW of large-scale fuel cell power installed or planned,” according to the Fuel Cell and Hydrogen Energy Association.
The US was also the top exporter of hydrogen in 2023 with US$2.15 billion in exports based on data from the Observatory of Economic Complexity (OEC).
Looking at the medium to long term, the use of hydrogen as a fuel source is expected to grow. While the strong government incentives enacted under former US President Joe Biden’s Inflation Reduction Act, such as a production tax credit, may be on the ropes under the Trump Administration, there is still optimism among industry leaders.

FAQS for hydrogen investing
Which is better: EVs or hydrogen?
According to research from TWI Global, there are pros and cons to both electric vehicles (EVs) and hydrogen vehicles. In terms of range and charging time, hydrogen beats electric hands down. However, while a hydrogen-powered vehicle doesn’t need much time to refuel compared to an EV, there is still much more EV charging infrastructure currently available compared to hydrogen fueling stations. EVs are also cheaper to purchase than hydrogen vehicles. As far as safety and emissions are concerned, it’s a draw between the two.
Why does Elon Musk not like hydrogen?
Elon Musk’s SpaceX has used hydrogen to fuel its rockets, and in 2023 Musk talked about hydrogen playing an important role in industrial applications, such as steelmaking. However, he has balked at the idea of hydrogen fueling vehicles, calling fuel cells “fool sells.” Speaking at a Financial Times conference in May 2022, Musk said, “It’s important to understand that if you want a means of energy storage, hydrogen is a bad choice.”
Starting in 2024, rumors began spreading that Tesla (NASDAQ:TSLA) was planning to launch a Tesla Model H powered by hydrogen, but they have been proven false.
Why is Toyota investing in hydrogen?
Toyota (NYSE:TM,TSE:7203) first invested in hydrogen fuel cell technology in 1992 as its executives saw clean energy as the future of transport. However, with EVs dominating the clean car space, the automaker began to shift its focus to compete with its peers. Toyota brought its newest hydrogen-powered vehicle to market in the fall of 2023 — a revamped Crown sedan that also has a hybrid-electric version. The following year, the auto maker introduced the first prototype of its Toyota Hilux trucks with a hydrogen fuel cell powertrain.
In 2025, Toyota shared its long-term strategy for developing hydrogen passenger vehicles as well as hydrogen technologies for long-haul freight.
Who is the leader in hydrogen energy?
Some countries leading in green and blue hydrogen production are the US, Germany and Canada. Many countries around the world have released clean hydrogen strategies, including the US, Canada and many countries in the Europe Union. However, clean hydrogen production is still in the early phases as countries develop infrastructure.
