Buyer’s Guide

The energy market is in the midst of a large transition away from fossil fuels and toward clean and renewable sources of energy. While there will be losers in this changeover, there will inevitably also be winners. 

To find a hydrogen stock to invest in, you will need to look at certain aspects of the company and do some research into their key metrics. Below are a few factors to consider. 

Innovation & Development

Innovation in the hydrogen sector has pushed some companies to the forefront of the market. Plug Power has been a pioneer in hydrogen fuel cell technology and created the first viable market for fuel cells powered by hydrogen. 

Bloom Energy is also pushing the boundaries of innovation and development in the hydrogen fuel cell industry in its effort to make reliable and clean energy which is also affordable. 

The Bloom Electrolyzer built on the success of the Bloom Energy Server but increased the efficiency, making it up to 45% more efficient than other electrolyzers on the market. 

A fuel cell developed by Ballard Power Systems features a proton exchange membrane that runs on hydrogen and produces zero emissions.

It also collaborated with Chart Industries to develop a liquid hydrogen fuel cell and worked with a Swiss company to make ship fuel cells.

Air Products and Chemicals, has a $4.5 billion blue hydrogen project in Louisiana. Blue hydrogen is when natural gas is split into hydrogen and carbon dioxide. This is done either by Steam Methane Reforming (SMR) or Auto Thermal Reforming (ATR). 

The carbon dioxide is captured and stored underground to mitigate any negative effects on the environment. This is opposed to gray hydrogen, which is produced in the same way, but the carbon dioxide is released into the atmosphere. 

Fusion Fuel Green claims that they can produce green hydrogen as cheaply as gray hydrogen through their solar-powered electrolyzers. 


Plug Power has a partnership with Renault, the French car manufacturer, and with Edison Motors, based in South Korea. In the US, it has teamed up with hydrogen and natural gas platform Certarus USA Ltd. 

In India, NTPC Limited, the country’s largest energy conglomerate, used Bloom Energy’s Electrolyzer for the construction of its green hydrogen microgrid. The company also agreed a deal with South Korea’s SK Group to supply power in a $4.5 billion agreement. 

Ballard Power Systems has also formed alliances with companies based in India. Mostly notably with Tata Motors to produce electric buses, but also with the Adani Group. Ballard and Adani will evaluate the commercialization of hydrogen fuel cells in India. 

The company also worked with the Swiss industrial giant ABB to develop hydrogen fuel cells that could be used to power ships. 

Air Products & Chemicals entered into a partnership with Saudi Arabia in a joint venture to produce 650 tons of gas every day as part of a $7 billion carbon-free hydrogen project. 

It has recently opened a state of the art refueling station in Shandong, China. 

Fusion Fuel Green entered into a collaboration with Toshiba Energy Solutions in order to evaluate Toshiba’s membrane electrode assemblies. These are  a core component of proton exchange membrane electrolyzers used in hydrogen production. 

Market Expansion

Plug Power intends to expand its hydrogen generation capability in the future, which includes building new hydrogen production facilities. This is part of its long term vision to create a green hydrogen infrastructure. 

The company already owns one of the few end-to-end hydrogen ecosystems in the world. In effect, this means it produces, liquefies, stores, transports and distributes the hydrogen. 

Bloom Energy hopes that its Electrolyzer will be adopted by heavy industries, e.g., cement, chemical or steel as it reduces the amount of carbon dioxide released into the atmosphere. The decarbonization of heavy industries would be a huge win for the hydrogen industry.

Air Products and Chemicals is already the world’s largest supplier of merchant hydrogen gas. It also has 60 years of experience in hydrogen production. Neither of these preclude the company from having expansion plans, which it certainly does. 

It wants to solve the environmental and energy problems the world is facing and intends to do this through clean hydrogen, carbon capture and gasification.

Hence, its billion dollar net-zero hydrogen project in Canada and  $4.5 billion blue hydrogen project in Louisiana. 

Fusion Fuel Green is well-placed to expand its hydrogen production in Europe, which is fully supporting the transition from fossil fuel to clean renewable energy. 

Combined with their commitment to invest €600 million in further projects, expansion is highly likely, given that they have their own green hydrogen farms and claim that their solar-powered electrolyzers can produce green hydrogen as cheaply as gray hydrogen.

Frequently Asked Questions

Is Hydrogen Stock A Good Investment?

Hydrogen is one of the most promising alternatives to fossil fuels and has huge potential. It has the capacity to provide a net-zero world in terms of carbon dioxide by replacing natural gas and decarbonizing heavy industry. 

The fact that it is emission-free is a huge draw for investors as governments all over the world push for a transition away from fossil fuel energy and toward clean, renewable energy. 

Although green hydrogen is still relatively expensive to produce, the costs are coming down and this trend will continue as more research and development is applied to hydrogen production. 

There are already companies such as Fusion Fuel Green, who claim their solar-powered electrolyzers are capable of producing green hydrogen for the same cost as gray hydrogen. 

What Are The Challenges For Hydrogen?

There are a few challenges that need to be overcome before hydrogen takes over as the fuel of choice in the long term. 

The production costs of hydrogen from renewable sources which results in low carbon or near zero emissions are relatively high. Other less expensive methods of hydrogen production such as by fossil fuel feeds produce high amounts of CO2

Producing green hydrogen through electrolysis which produces low or zero emissions is energy intensive and therefore expensive. The production costs of electrolysis technology are also high. 

Gray hydrogen is by far the most widely produced globally, but there are associated carbon emissions. Blue hydrogen production does contain carbon emissions, but these are either captured or utilized. However, storage then becomes an issue and an expense. 

The future of clean energy most likely lies at the feet of hydrogen fuel cells. In and of  themselves, they contribute no emissions, but the production of hydrogen to fuel the cells still has a way to go before it can be considered clean.

Green hydrogen is expensive to produce so although the processes are there to make a net-zero world, the price is still high economically. However, there is hope that the use of solar and wind energy will make green hydrogen more affordable in the future. 

As an investment, hydrogen is a good bet and these are among the best companies in the production of hydrogen and its use as a fuel for clean energy. The hardest part may be which one to choose to add to your portfolio, 

We hope this guide has helped you choose the best hydrogen stock.
