Hydrogen stocks are publicly traded companies seeking to capitalize on the enormous potential of hydrogen. This energy source emits no greenhouse gases when burned. The only waste product is water vapor, making it a cleaner energy source than fossil fuels such as natural gas, oil, and coal. These features make it a potential future source of lower-carbon energy.
The drawback of hydrogen as a fuel source is that it's rarely found in an easily extractable form. Although hydrogen can be produced from a variety of sources, most methods emit greenhouse gases, and clean hydrogen has not yet been produced at the scale needed to be economically competitive with fossil fuels.
However, that could change in the coming years. Several companies are working hard to tap into the enormous promise of this potentially emission-free fuel.
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:
- Types of hydrogen: 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.
Carbon Credits
- Similar to batteries: Hydrogen fuel cells work much like batteries, generating electricity through an electrochemical reaction. However, hydrogen fuel cells are refueled with more hydrogen rather than being recharged like a traditional battery.
- Multiple current uses: Hydrogen fuel cells already have many uses. They're found in many motorized vehicles (e.g., cars, trains, buses, maritime vessels, and trucks) and also serve as a stationary power source.
- Massive market opportunity: Hydrogen has vast potential as a replacement fuel. It could one day replace natural gas in the pipeline system to generate electricity at power plants and as a fuel source for our homes. Due to its potential, some forecasts peg the future value of the clean hydrogen market as high as $11 trillion.
- Costs: Although clean hydrogen holds great promise as a potential emissions-free fuel source, it's costly to produce. It costs as little as $1.50 per kilogram to produce hydrogen from natural gas and between $3 and $12 per kilogram to produce clean hydrogen. The U.S. Department of Energy wants to reduce the cost of clean hydrogen to $1 per kilogram over the next decade to make it a more competitive fuel source.
Best hydrogen stocks to buy in 2025
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.
However, a handful of companies are already emerging as early leaders in the sector. Here are seven leading hydrogen companies to keep an eye on as the industry matures.
Air Products aspires to be a leader in providing solutions to the world's energy and environmental challenges through gasification, carbon capture, and clean hydrogen. It 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 and a $3.3 billion blue hydrogen project in Canada, as well as a smaller $360 million green hydrogen project in Arizona that could come online in 2026.

Investment considerations for hydrogen stocks
Hydrogen energy has enormous potential. The emissions-free fuel could help decarbonize heavy industry, replace natural gas, and store renewable energy, paving the way for a truly net-zero world. It represents a multitrillion-dollar market opportunity.
However, hydrogen is still developing as a commercially viable fuel source. The industry needs to scale up and reduce costs to become competitive with fossil fuels and other emerging technologies, such as battery storage. The industry also relies on government support in the form of loan guarantees and other tax incentives, which can change based on the outcome of elections.
Given these factors, investors should evaluate whether they can handle the risks associated with investing in hydrogen stocks. Many pure-play hydrogen companies are unprofitable, making them riskier. Meanwhile, other larger companies involved in the sector make most of their money elsewhere.
As a result, investors might want to watch the sector from the sidelines and wait for the sector to develop. Alternatively, you can consider investing in hydrogen by taking a basket approach (buying several different hydrogen stocks with varying risk profiles) or through a hydrogen ETF.
