Hydrogen is compelling because it can decarbonize areas that are hard to electrify, like heavy industry, long-haul transport, and potentially power generation and storage. The catch is that hydrogen isn’t a primary energy source. It has to be produced, and the cleanest methods cost more than fossil alternatives today.
That’s why hydrogen is best viewed as a long-duration theme: massive potential, but timelines and economics still need work.
What to know about investing in hydrogen
There are a few things investors should know about the hydrogen industry before investing in the sector, including:
- Not all hydrogen is the same: There are several ways to produce hydrogen, some of which produce carbon dioxide as a byproduct. The industry refers to hydrogen produced from burning natural gas as "blue hydrogen," which requires carbon capture and storage (CCS) to isolate greenhouse gas emissions. "Green hydrogen," produced by renewable energy to power an electrolyzer that splits hydrogen from water molecules, doesn't emit any greenhouse gases. Green and blue are two of the many colors used to classify hydrogen by its production method and emissions profile.
- The key variable is cost: Right now, producing hydrogen from natural gas can be much cheaper than producing clean hydrogen. A lot of the bull case assumes clean hydrogen costs fall sharply over time, which depends on technology, scale, and policy support.
- Massive market opportunity, but adoption is difficult: Hydrogen already has meaningful industrial uses, and fuel cells are being deployed in certain vehicles and stationary power setups. But big growth depends on project approvals, infrastructure buildout, and long-term offtake contracts.
- Hydrogen stocks are not one “category”: "Hydrogen stocks” can mean very different things. Some are large industrial and energy companies where hydrogen is one growth lever among many. Others are pure-play fuel cell or electrolyzer companies that depend heavily on funding, policy, and project timing. That difference matters, not just for potential upside, but for volatility and risk.
Top hydrogen stocks to consider
Given the potential of clean hydrogen, a growing number of companies are investing in the sector. Many energy and industrial companies are in the early stages of exploring the possibility of hydrogen energy.
Here are seven leading hydrogen companies to keep an eye on as the industry matures.
NYSE: APD
Key Data Points
Air Products has several major hydrogen projects underway that it expects to complete in the coming years. For example, it has completed 80% of the construction of its NEOM Green Hydrogen Project in Saudi Arabia, which should begin production by 2027. It's also working on a potential $8 billion blue hydrogen project in Louisiana that it could approve by the middle of 2026. In December 2025, Air Products reported that it was in advanced negotiations to potentially connect these projects to Yara's world-scale ammonia network.
2. Ballad Power Systems
NASDAQ: BLDP
Key Data Points
4. Bloom Energy
NYSE: BE
Key Data Points
Bloom Energy's (BE +1.27%) mission is to produce clean, reliable, and affordable energy. The company has developed the Bloom Energy Server, an electric power-generation platform. It also created the Bloom Electrolyzer, using the same solid oxide technology as its Bloom Energy Server. The product can produce clean hydrogen 15% to 45% more efficiently than others on the market.
Bloom Energy believes the Bloom Electrolyzer is a major leap forward for hydrogen. It hopes the technology will enable heavy industries, such as steel, chemicals, cement, and glass manufacturing, to decarbonize.
Bloom Energy can pair its Bloom Electrolyzer with solar energy and wind energy to generate green hydrogen, which it can store and eventually turn back into electricity for future use. It has the potential to be the solution of choice for powering artificial intelligence (AI), including data centers and businesses using the technology for productivity gains.
In October 2025, Bloom Energy and Brookfield Asset Management (BAM +0.99%) announced a strategic AI infrastructure partnership. Brookfield will invest as much as $5 billion to deploy Bloom's advanced fuel cell technology in AI data centers in the future.
5. Linde
NASDAQ: LIN
Key Data Points
Linde (LIN -3.15%) has developed several technologies to efficiently compress and safely refuel hydrogen. It also offers technologies to lower hydrogen's carbon emissions through carbon capture and storage.
Linde is building a 100-megawatt renewable hydrogen plant for Shell (SHEL +1.07%) in Germany, which it expects will begin commercial operations in 2027.
In June 2025, Linde signed a long-term agreement to supply industrial gases to a $4 billion low-carbon ammonia facility currently under construction in Louisiana. Linde will invest $400 million in a new on-site facility that will complement the company's existing hydrogen and syngas (synthesis gas) infrastructure in the region.
While Linde is an early hydrogen leader, it has been skeptical of the sector's near-term growth prospects. The company believes it will take five to seven years for hydrogen technology to mature. As that happens, the industry will be able to approve more commercially viable projects.
6. Cummins
NYSE: CMI
Key Data Points
Cummins (CMI +5.68%) is a global power solutions company. It makes advanced diesel, natural gas, electric, and hybrid powertrains and powertrain-related parts. Among its solutions are fuel cell and electric power technologies and hydrogen production technologies. Accelera by Cummins is its business segment dedicated to zero-emissions technology, such as fuel cell engines.
In February 2026, Cummins announced that it intends to stop new commercial activity in the electrolyzer space (part of its Accelera segment) due to deteriorating market conditions. Cummins, like others in the hydrogen sector, has had to meaningfully temper their hydrogen adoption expectations over the past year.
7. FuelCell Energy
Benefits and risks of investing in hydrogen stocks
Investing in hydrogen stocks has its share of pros and cons. Some benefits of investing in hydrogen stocks include:
- Growth potential: Hydrogen could become a multitrillion-dollar global market in the coming decades, potentially fueling strong gains for top hydrogen stocks.
- Cleaner: Hydrogen (green hydrogen and blue hydrogen paired with CCS) is a cleaner fuel source compared to oil and natural gas, so investing in the sector can help support the environment.
- Diversification: Investing in the hydrogen sector can help diversify your portfolio.
- Income potential: Some hydrogen stocks pay dividends, enabling you to generate some passive income.
On the other hand, some risks of investing in hydrogen stocks include:
- Market challenges: The hydrogen market can be very challenging due to the volatility of hydrogen prices and changing government policies. These and other issues have caused some hydrogen companies to cancel major expansion projects.
- Higher risk companies: Many hydrogen companies have higher risk profiles due to their weaker balance sheets and lack of profitability.

- Review your purchase: Check your portfolio to ensure your order was filled as expected and adjust your investment strategy accordingly.
Future outlook for the hydrogen fuel industry
Several energy companies have delayed or canceled hydrogen projects over the past year due to challenging market conditions. However, the industry's outlook remains bright. According to the International Energy Agency, "Projects that are operational, under construction, or have reached a final investment decision by 2030 are set to increase more than fivefold from 2024 levels to more than 4 million tonnes per year. An additional 6 million tonnes per year also has strong potential to become operational by 2030 if effective policies to ensure demand are implemented." This robust growth rate bodes well for hydrogen stocks.
Investment considerations for hydrogen stocks
Hydrogen has enormous long-term potential, with the ability to help decarbonize heavy industry, replace natural gas in some uses, and store renewable energy. If the technology scales, it could support a multitrillion-dollar global market.
At the same time, hydrogen is still early in its commercial development. Clean hydrogen remains expensive to produce, and wider adoption depends on cost reductions, infrastructure buildout, and ongoing policy support, all of which can change over time.
Because of that uncertainty, hydrogen stocks tend to carry higher risk. Many pure-play companies are unprofitable, while larger firms involved in hydrogen generate most of their revenue elsewhere. For investors, that means hydrogen may be better approached cautiously, either as a small thematic allocation, a basket of companies with different risk profiles, or through a hydrogen ETF.
