Hydrogen-powered cars, also known as fuel cell vehicles (FCVs), do exist and have been developed by several automakers. These vehicles use hydrogen gas to generate electricity through a chemical process within a fuel cell, which then powers an electric motor to propel the vehicle. Hydrogen fuel cell technology has been under development for several decades, and there are already some hydrogen-powered cars available in limited markets.
Do hydrogen powered cars represent an investment opportunity? Are electric vehicle companies based on lithium battery technology vulnerable to changing technologies? Helping sort out where the investing opportunities are is the stock market newsletter ‘Capitalist Exploits’ which counts many hedge fund managers among their subscribers.
Here are some key points regarding hydrogen-powered cars:
Existing Models: Some automakers, such as Toyota, Honda, and Hyundai, have introduced hydrogen fuel cell vehicles like the Toyota Mirai, Honda Clarity Fuel Cell, and Hyundai NEXO. These vehicles are primarily available in select regions with hydrogen refueling infrastructure, such as California in the United States and parts of Europe and Asia.
Challenges: Hydrogen-powered cars face several challenges, including not only the limited availability of hydrogen refueling stations, but more importantly the current extremely high cost of producing and storing hydrogen, and the large amount of energy required for hydrogen production. These challenges have hindered the widespread adoption of hydrogen FCVs but that may change in the future.
Environmental Considerations: The environmental benefits of hydrogen-powered cars depend on how the hydrogen is produced. If hydrogen is produced using renewable energy sources like wind or solar power, it can be considered a clean and sustainable fuel. However, most of the world’s hydrogen is currently produced from natural gas in a process called steam methane reforming (SMR), which emits carbon dioxide. Transitioning to green hydrogen production methods is essential for reducing the carbon footprint of hydrogen-powered vehicles.
Competition from Battery Electric Vehicles (BEVs): Hydrogen FCVs face competition from battery electric vehicles (BEVs), which have gained significant popularity due to advancements in battery technology and an expanding charging infrastructure. BEVs are often seen as a more established and practical option for many consumers.
Some companies believe there is a bright future for hydrogen and that the current electric vehicles powered by lithium batteries are just an interim technology. Watch this video below from Porsche:
Specialized Use Cases: Hydrogen fuel cell technology may find more significant adoption in specific applications, such as commercial vehicles like buses and trucks, where longer range and shorter refueling times are critical factors.
Ongoing Research and Development: Research into hydrogen production, storage, and distribution continues, with a focus on addressing the challenges associated with hydrogen as a fuel source. Advancements in these areas could improve the viability of hydrogen-powered transportation in the future.
It’s important to note that the development of technology and infrastructure can change rapidly, so the status of hydrogen-powered cars may have evolved since my last update in September 2021. However, as of that time, hydrogen FCVs faced significant challenges that limited their widespread adoption in the passenger vehicle market, but they still had potential for specialized applications and continued development.
