Hydrogen Stocks: 9 Biggest Companies in 2025

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 picture has become a little more opaque after the new Trump administration targeted some of the strong government incentives.

In July 2025, 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.

1. Linde (NYSE:LIN)

Market cap: US$222.58 billion
Share price: US$474.69

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 2025 results reported a 3 percent year-over-year uptick in overall sales to US$8.5 billion.

2. Air Products & Chemicals (NYSE:APD)

Air Products has an extensive hydrogen-dispensing technology patent portfolio and has been involved in more than 250 hydrogen-fueling projects worldwide.

Air Products also has a joint venture project now under construction with ACWA Power (SR:2082) and NEOM Company in Saudi Arabia. Called the NEOM Green Hydrogen Complex, the operation will be powered by 4 gigawatts of renewable power from solar and wind to produce 600 metric tons per day of carbon-free hydrogen, which it says will be delivered in the form of green ammonia. Once production begins at the complex in 2026, Air Products will be the sole off-taker and plans to deliver the green ammonia to Europe’s transport sector.

Air Products’ Louisiana Clean Energy Complex, its largest US investment, is also making headway, with first production expected in 2028. The complex will produce blue hydrogen for power mobility and industrial markets in the Gulf Coast region and other markets.

In August 2025, Air Products completed the first fill of NASA’s new liquid hydrogen sphere, the largest of its kind in the world, delivering over 730,000 gallons of hydrogen. Standing 90 feet tall and 83 feet wide, the sphere will supply fuel for NASA’s Artemis missions, which aim to return humans to the Moon and establish a sustained lunar presence. The company has been working with NASA since 1957.

3. Cummins (NYSE:CMI)

Market cap: US$53.97 billion

The following month heralded the launch of Accelera’s next-gen hydrogen fuel cell technology for commercial vehicles, specifically the FCE300 and FCE150 fuel cell engines.

Accelera inked a deal in February 2025 to supply a 100 megawatt PEM electrolyzer system for BP’s (LSE:BP,NYSE:BP) Lingen green hydrogen project in Germany. The system is Accelera’s largest to date and uses its HyLYZER PEM electrolyzer technology.

In March 2025, 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 British Columbia, the Government of Canada 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 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.

1. Hazer Group (ASX:HZR)

Market cap: AU$91.62 million
Share price: AU$0.34

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 British Columbia 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 in March 2025 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,’ the press release states.

In June, Hazer entered a non-binding MOU 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.
