1. Understanding Hydrogen Cars
Hydrogen cars, also referred to as hydrogen fuel cell electric vehicles (FCEVs), employ hydrogen fuel cells to generate electricity, which in turn powers their electric motors. These vehicles are gaining traction due to their energy efficiency, extended driving range, reduced reliance on fossil fuels, and swift refueling capabilities.
According to the International Energy Agency’s (IEA) Global EV Outlook 2023 report, the number of hydrogen cars worldwide experienced a 40% increase in 2022. Despite this increase, significant challenges and disadvantages remain that potential buyers should consider.
2. How Hydrogen Cars Operate
Instead of relying on electricity stored in a lithium-ion battery, hydrogen cars generate electricity through a chemical reaction between hydrogen and oxygen within a fuel cell stack. Here’s a breakdown of the process:
- Extraction: Hydrogen is sourced from various resources, including fossil fuels, biomass, and water electrolysis using electricity. In the U.S., most hydrogen is produced at large industrial sites and transported via pipelines, high-pressure tube trailers, or liquefied hydrogen tankers.
- Compression and Storage: Hydrogen is compressed and stored onboard in carbon-fiber-reinforced high-pressure tanks.
- Fuel Cell Interaction: Compressed hydrogen is fed into an onboard fuel cell stack, where it combines with oxygen to produce electricity. The fuel cell acts similarly to a battery, with hydrogen entering the anode, causing hydrogen atoms to separate into electrons and protons upon exposure to oxygen.
- Electricity Generation: The electrons are directed, via a conductive current collector, to the vehicle’s high-voltage circuitry, powering the car’s electric motors, which in turn propel the wheels.
- Emission: Water vapor, the sole byproduct of the chemical reaction between hydrogen and oxygen, is emitted through the car’s exhaust.

| Storage Challenges | Hydrogen’s low energy density poses challenges for efficient storage and transportation. |
| Model Scarcity | Only a few hydrogen car models are available, limiting consumer choice. |
5. Environmental Implications of Hydrogen Cars
A typical passenger vehicle emits around 4.6 metric tons of carbon dioxide annually, along with nitrogen oxides, hydrocarbons, and particulate matter, contributing to global warming and air pollution.
Electric cars are often celebrated as a greener alternative, but how do hydrogen fuel cell vehicles stack up?
To achieve a significant environmental impact, both electric and hydrogen cars must utilize renewable energy for electricity and hydrogen production.
In 2022, around 60% of electricity generation in the U.S. came from fossil fuels, while most hydrogen is extracted from natural gas, releasing carbon dioxide as a byproduct.
Additionally, the environmental and societal impact of raw material extraction, battery production, vehicle assembly, storage, and transportation must be considered.
A study by the International Council on Clean Transportation indicated that battery electric trucks and buses could reduce GHG emissions by up to 92% compared to diesel counterparts when using 100% renewable electrical energy. Similarly, hydrogen-powered electric trucks and buses could reduce GHG emissions by up to 89% if the hydrogen is produced solely with renewable electricity.
6. Addressing Infrastructure Challenges
Overcoming infrastructure challenges is vital for hydrogen car adoption:
6.1 Storage and Transportation Enhancements
Hydrogen’s low volumetric energy and near-absolute zero boiling point complicate its transportation and storage. The complexities of codes and standards further add to these challenges.
To meet growing demand, hydrogen must be transported in large quantities via pipelines, gaseous tube trailers, or cryogenic liquid tanker trucks to refueling stations nationwide. The necessary infrastructure for this scale of distribution is currently lacking.
Expanding existing storage solutions is equally important. The Department of Energy is funding the Advanced Clean Energy Storage project to provide long-term seasonal energy storage. Additional facilities like this could facilitate a smoother transition to hydrogen cars.
6.2 Expanding Hydrogen Refueling Stations
The scarcity of refueling stations is a major impediment. As of 2023, there are only 59 open hydrogen stations in the United States, mostly in California, limiting the range and reach of hydrogen cars.
Government initiatives, such as the Department of Energy’s grant awards, aim to develop hydrogen refueling station plans across the Midwest corridor and between Houston and Los Angeles, promoting nationwide deployment.
7. Navigating Production Costs and Hurdles
Several key challenges affect the production of hydrogen-powered vehicles:
Extraction, transportation, and storage of hydrogen are time-consuming and energy-intensive. The U.S. lacks the infrastructure to handle the vast quantities required for widespread adoption.
Hydrogen fuel cells also rely on precious metals, such as platinum and iridium, which are costly and difficult to acquire.
Improving the efficiency and viability of hydrogen fuel cell technology is essential. Currently, the cost per unit of power from hydrogen fuel cells is higher than many other energy sources.
These production challenges contribute to the high purchase price of hydrogen-powered cars.
