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.
This segment is projected to see massive growth over the next two decades led by increased output from China.
According to an August report from S&P Global, in 2050 China is forecasted to produce 33.4 million metric tons of zero-emission electrolytic hydrogen, while the European Union will produce 20 million metric tons, and the US, 4.7 million.
The research firm's 2050 forecast for China tripled compared to last year's report as the country rapidly raises its production capacity and signs offtake agreements with green hydrogen projects globally.
Below the Investing News Network profiles the biggest hydrogen companies by market cap on US, Canadian and Australian stock exchanges. Data was gathered on September 2, 2025, using TradingView’s stock screener.
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 megawatts 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 picture has become a little more opaque after the new Trump administration targeted some of the strong government incentives.
This past July, Congress cut the window for Section 45V hydrogen tax credits by five years, requiring green hydrogen projects to begin construction before 2028 to be eligible. The move comes alongside the Trump administration’s decision to delay hydrogen loans and cancel emissions-reduction grants.
These changes prompted Commodity Insights analysts to halve their forecast for 2050 US green hydrogen production to 4.7 million metric tons compared to their 2024 prediction of 9.3 million. The firm also reduced its 2030 forecast for US electrolyzer installations by 60 percent to 2.5 million gigawatts.
While green hydrogen faces setbacks, blue hydrogen remains supported by Section 45Q carbon capture credits and demand from Japan and South Korea.

Leading global industrial gases and engineering company Linde has been producing hydrogen for more than a century and is a pioneer in new hydrogen production technologies.
Linde’s operations cover each step of the hydrogen value chain, from production and processing through distribution and storage. The company also uses its gases for industrial and consumer applications.
Globally, the company has more than 500 hydrogen production plants. Through its ITM Linde Electrolysis joint venture, Linde has become one of the world’s leading suppliers of green hydrogen produced using proton exchange membrane (PEM) electrolyzer technologies. This also makes it one of the few green hydrogen stocks.
In August 2024, Linde signed a US$2 billion long-term supply agreement to supply clean hydrogen to Dow (NYSE:DOW) subsidiary Dow Canada's Path2Zero project in Fort Saskatchewan, Alberta.
In response to the regulatory uncertainties under the Trump administration, Linde announced in its Q4 2024 earnings call that 90 percent of its US clean hydrogen projects will be focused on blue hydrogen, which is created by reforming natural gas with carbon capture storage. Blue hydrogen is more cost effective to produce, and although it is not zero emission like green hydrogen, it is more environmentally friendly than grey hydrogen produced with coal.
While Linde does not report separated data for its hydrogen segment, the company's Q2 results reported a 3 percent year-over-year uptick in overall sales to US$8.5 billion.

In March, Cummins joined academics, energy leaders and transportation experts as a founding member of the Hydrogen Engine Alliance of North America, which aims to advance hydrogen internal combustion engines (H2-ICE) alongside zero-emission technologies to support sectors where electrification isn't possible yet. Cummins is preparing to launch its X15H hydrogen engine under its HELM platform.
Canadian hydrogen stocks
Like its neighbor to the south, Canada is a world leader in hydrogen and fuel cell technologies, especially when it comes to innovation, research and development. The country reportedly generates C$200 million in hydrogen technology exports, according to data from January 2023. In terms of the global hydrogen market, the country exported $385 million worth of hydrogen in 2023, ranking ninth overall, according to the OEC.
The federal government is heavily invested in the sector both in terms of funding and the implementation of clean energy policies. “The Hydrogen Strategy for Canada laid out a framework that focuses low-carbon hydrogen as a tool to achieve our goal of net-zero emissions by 2050, while creating jobs, growing our economy, expanding exports and protecting our environment," Natural Resources Canada states.
In BC, the Canadian government has invested C$9.4 billion to launch a new Clean Hydrogen Hub that will use electrolyzer technology and hydroelectricity to generate hydrogen that can be sold to industry users.
On the global stage, Canada and its trading partner Germany have agreed to each commit C$300 million for a total of C$600 million to launch Atlantic Canada's hydrogen export industry, which will send hydrogen to Germany. However, delays due to factors including high hydrogen prices and inflation as well as lack of infrastructure have pushed the expected start of exports back from 2025.

The site will focus on research, development and collaboration to support local demand and advance clean transport solutions.
The company will also move its European manufacturing operations to its existing technology center in Canada, uniting its manufacturing capacity with its North American innovation hub. It also plans to increase its focus on expanding Cespira's market presence to North America.
Australian hydrogen stocks
Australia is another important hotspot for investing in hydrogen.
The Australian government says that "over AU$200 billion is currently in the investment pipeline for hydrogen and derivatives," accounting for 20 percent of announced renewable hydrogen projects worldwide.
The Australian government’s National Hydrogen Strategy, which it updated in 2023, highlights its intention to position the country as a “major player” in the global hydrogen market by 2030.
To this end, Australia has partnered with a number of other nations on hydrogen technology.
Australia and Germany are working together on a hydrogen technology development program that will help Australia build out its capacity to export hydrogen to Germany as it seeks to reduce its reliance on fossil fuels.
Through a partnership with Japan, Australia is developing new hydrogen fuel cell technology and looking to establish the world's first clean liquefied hydrogen export pilot project, and its government has invested more than AU$500 million in the development of regional hydrogen hubs across the country.
In May 2024, the Australian government announced an AU$22.7 billion package to bolster the country's domestic manufacturing and renewable energy sector, including AU$6.7 billion for renewable hydrogen production starting in mid-year 2028 through the 2039/2040 fiscal year.

Technology development company Hazer Group is working to commercialize the HAZER Process, a low-emission hydrogen and graphite production process initially developed at the University of Western Australia. It uses iron ore as a process catalyst to convert natural gas and similar feedstocks into hydrogen for use as an industrial chemical and in fuel cells, as well as into high-quality synthetic graphite for use in lithium-ion batteries.
Hazer started operations at its commercial demonstration plant in early 2024 and it is now producing hydrogen and graphitic carbon. In May 2024, the company inked an agreement with Canadian utility company FortisBC for the development of a hydrogen production facility in BC, Canada, that will use Hazer’s proprietary technology. The proposed commercial production facility will have a design capacity of up to 2,500 metric tons per year of clean hydrogen and approximately 9,500 metric tons per year of Hazer graphite.
The company announced this past March that it had successfully completed its commercial reactor test program, validating a commercial scale-up reactor design. "The equipment was designed to mimic key aspects of the Hazer Process for producing hydrogen and graphite at commercial scale, and the completion of this testing is a major milestone for the government support from CleanBC," a press release states.
In June, Hazer entered a non-binding memorandum of understanding with UK-based EnergyPathways to explore a hydrogen production facility within the Marram energy storage hub in Northwest England. The proposed plant would produce up to 20,000 metric tons of hydrogen annually, alongside ammonia and graphite using feedstock from Marram. Both parties plan to move toward a binding agreement following concept engineering studies.
In a July update, Hazer Group said its strategic alliance with Kellogg Brown and Root (NYSE:KBR) is advancing the global commercial rollout of the Hazer Process. Now in full execution, the partnership has deployed teams across Australia, the UK and the US.

In August 2024, Pure Hydrogen registered Australia's first hydrogen-powered semi-truck, the Hydrogen Fuel Cell 110kW 6x4 Prime Mover.
Pure Hydrogen's majority-owned subsidiary HDrive confirmed this past January that it had sold two Taurus 70 metric ton hydrogen fuel cell prime movers to Australian logistics services provider TOLL Transport as part of a broader AU$2 million package. The vehicles are slated for delivery in the fourth quarter of the calendar year.
In April, Pure Hydrogen executed a commercial agreement with hydrogen technology provider Hydrexia, granting access to Hydrexia's mobile hydrogen refueling stations and related service support through a phased delivery. Hydrexia specializes in hydrogen solutions for production, storage, transport and end-use applications.
As noted in a statement, the rollout marks the first stage of broader cooperation between the companies to support hydrogen development in Australia and internationally.
Pure Hydrogen signed a strategic distribution deal for the South American market with an Argentinian renewable energy company in July. The company has also made multiple significant sales of its hydrogen fuel cell trucks in Q3, including its first North American sale of a hydrogen cell refuse truck as part of a term sheet with California-based Riverview International Trucks. In the Australian market, it sold two Prime Mover trucks to one company and a second concrete agitator truck to another, worth over AU$3 million combined.
Pure Hydrogen proposed a rebranding and company name change to Pure One in July, which shareholders will vote on at its annual general meeting later this year.
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 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.
