The Rise of Hydrogen Fuel Cell Vehicles
Hydrogen fuel cell vehicles (FCEVs) are at the heart of the automotive industry’s adaptation to hydrogen technology. These vehicles use a fuel cell stack to convert hydrogen gas into electricity, which powers an electric motor. The process is clean, quiet, and efficient. Unlike battery EVs, which can take hours to recharge, FCEVs can be refueled in just 3 to 5 minutes—similar to filling up a gas tank. This speed and convenience make hydrogen particularly appealing for drivers who need quick turnarounds, such as delivery services or long-distance travelers.
One of the most well-known FCEVs on the market is the Toyota Mirai. Launched in 2014, the Mirai was one of the first mass-produced hydrogen cars. It offers a range of over 400 miles on a single tank and emits only water from its tailpipe. Hyundai has also made significant strides with its NEXO SUV, which boasts advanced safety features and a sleek design. Both vehicles are available in select markets, primarily in California, Japan, and parts of Europe, where hydrogen refueling stations are more common.
How Fuel Cells Work
At the core of every FCEV is the fuel cell stack. This system combines hydrogen from the vehicle’s tank with oxygen from the air. The reaction produces electricity, heat, and water. The electricity powers the motor, while the water exits as vapor. The fuel cell itself contains an anode, a cathode, and an electrolyte membrane. Hydrogen molecules split into protons and electrons at the anode. The protons pass through the membrane to the cathode, while the electrons travel through an external circuit, generating electric current. At the cathode, protons, electrons, and oxygen combine to form water.
This process is highly efficient—modern fuel cells convert 60% or more of the energy in hydrogen into usable electricity, compared to about 20–30% for internal combustion engines. And because there’s no combustion, there are no harmful emissions like nitrogen oxides or particulate matter.
Advantages Over Battery Electric Vehicles
While battery EVs have gained widespread popularity, hydrogen FCEVs offer several distinct advantages. First, refueling time is dramatically shorter. A five-minute fill-up is far more practical for commercial fleets and long-distance travel than waiting 30 minutes to several hours for a battery charge. Second, FCEVs typically have longer ranges. Most models exceed 300 miles, with some reaching over 400, making them ideal for highway driving and rural areas with sparse charging networks.
Another benefit is weight. Batteries are heavy, and larger batteries needed for long-range EVs can reduce vehicle efficiency and performance. Hydrogen tanks are lighter and take up less space, allowing for better weight distribution and design flexibility. This is especially important for trucks and buses, where every pound counts.

Several major automakers are investing heavily in hydrogen technology, recognizing its potential to complement—or even compete with—battery electric vehicles. These companies are not just building cars; they’re shaping the entire hydrogen ecosystem.
Toyota has been a pioneer in hydrogen mobility. Beyond the Mirai, the company is developing hydrogen-powered trucks, buses, and even forklifts. In 2021, Toyota partnered with Hino Motors to create a fuel cell truck for the Japanese market. The vehicle is designed for long-haul freight and can travel up to 600 kilometers on a single tank. Toyota is also working on stationary fuel cells for homes and businesses, showing how hydrogen can power more than just vehicles.
Hyundai is another leader. The Korean automaker has committed to becoming a top-tier hydrogen company by 2030. Its NEXO SUV is already available in over 10 countries, and Hyundai is scaling up production of its XCIENT Fuel Cell trucks. These heavy-duty vehicles are being deployed in Switzerland, Germany, and the U.S., with plans to expand globally. Hyundai’s vision includes a full hydrogen value chain—from production to refueling—making it a one-stop shop for hydrogen mobility.
BMW is also stepping into the hydrogen game. While the German automaker remains focused on battery EVs, it has announced plans to launch a hydrogen-powered version of its X5 SUV by 2025. The vehicle will use a fuel cell system developed in partnership with Toyota. BMW believes hydrogen will play a key role in decarbonizing transport, especially for larger vehicles and long-distance travel.
Collaboration and Joint Ventures
The shift to hydrogen isn’t happening in isolation. Automakers are forming strategic partnerships to share technology, reduce costs, and accelerate development. The Toyota-Hyundai collaboration on fuel cell systems is one example. Another is the partnership between General Motors and Honda, which co-developed the next-generation fuel cell system used in the Honda Clarity Fuel Cell and GM’s Hydrotec platform.
These collaborations help spread the high costs of R&D and manufacturing. Fuel cells are still expensive due to the use of platinum catalysts and complex engineering. By pooling resources, companies can bring down prices and improve performance faster. Joint ventures also help standardize components, making it easier to build a global hydrogen infrastructure.
Overcoming Infrastructure Challenges
One of the biggest hurdles to widespread hydrogen adoption is infrastructure. Unlike gasoline stations or EV chargers, hydrogen refueling stations are still rare. As of 2023, there are fewer than 1,000 hydrogen stations worldwide, with the majority in California, Japan, Germany, and South Korea. This scarcity limits where FCEVs can be driven and discourages consumer adoption.
But the situation is improving. Governments and private companies are investing billions in hydrogen infrastructure. California, for example, has a goal of 200 hydrogen stations by 2025. The state currently has over 50 operational stations, mostly in the Los Angeles and San Francisco Bay areas. These stations are often co-located with gas stations or built near major highways to serve long-distance travelers.
Types of Hydrogen Stations
Hydrogen refueling stations come in different types. The most common are retail stations that serve passenger vehicles. These look similar to gas stations, with pumps that dispense compressed hydrogen gas at high pressure (typically 700 bar). Some stations are mobile or temporary, used for testing or special events.
Another type is on-site production stations, where hydrogen is generated directly at the station using electrolysis or natural gas reforming. These are useful in remote areas or for fleet operations. For example, a logistics company might install a small electrolyzer at its warehouse to fuel delivery trucks.
Building a Global Network
Countries around the world are developing national hydrogen strategies. The European Union has launched the European Hydrogen Strategy, aiming to install at least 10 million tons of renewable hydrogen production capacity by 2030. Germany alone plans to build 100 hydrogen stations by 2025. Japan’s “Basic Hydrogen Strategy” targets 900 stations by 2030, up from around 160 today.
China is also investing heavily. The country has the world’s largest fleet of hydrogen buses and is expanding its refueling network rapidly. In 2022, China opened its first hydrogen highway, with stations spaced every 100 kilometers along a major freight route.
Private companies are stepping up too. Shell, TotalEnergies, and Air Liquide are building hydrogen stations across Europe and North America. In the U.S., companies like Plug Power and Nikola are developing hydrogen infrastructure for heavy-duty transport, including truck stops and logistics hubs.
Hydrogen in Heavy-Duty and Commercial Transport
While passenger cars get most of the attention, hydrogen is making its biggest impact in heavy-duty and commercial transport. Trucks, buses, trains, and even ships are ideal candidates for hydrogen technology due to their high energy demands and long operating hours.
Long-haul trucks, for example, need to travel hundreds of miles without stopping. Battery electric trucks are improving, but their range and charging time are still limiting factors. Hydrogen trucks, on the other hand, can match the range and refueling speed of diesel trucks. Companies like Nikola, Hyzon Motors, and Daimler Truck are developing hydrogen-powered semis for freight transport.
Hydrogen Buses Leading the Way
Public transit is one of the earliest adopters of hydrogen. Cities like London, Aberdeen, and Cologne have deployed hydrogen buses that run on fixed routes. These buses emit zero pollutants, improving air quality in urban areas. They’re also quieter than diesel buses, reducing noise pollution.
The fuel cell buses used in these fleets are highly efficient and reliable. Many can operate for over 20 hours on a single tank, making them ideal for daily transit schedules. Maintenance costs are lower than diesel buses, and the only byproduct is clean water.
Trains and Maritime Applications
Hydrogen is also powering trains. In Germany, Alstom’s Coradia iLint is the world’s first hydrogen-powered passenger train. It runs on non-electrified rail lines, replacing diesel trains and reducing emissions. Similar projects are underway in the UK, France, and Italy.
In maritime transport, hydrogen and ammonia (a hydrogen carrier) are being explored as clean fuels for ships. Companies like Maersk and CMA CGM are investing in hydrogen-based solutions to meet international emissions targets. While still in early stages, hydrogen could play a major role in decarbonizing global shipping.
Green Hydrogen: The Key to Sustainability
Not all hydrogen is created equal. The environmental benefits of hydrogen depend on how it’s produced. Currently, most hydrogen is made from natural gas through a process called steam methane reforming (SMR). This method, known as “gray hydrogen,” emits significant amounts of CO₂.
To be truly sustainable, hydrogen must be produced using renewable energy. This is where “green hydrogen” comes in. Green hydrogen is made by splitting water into hydrogen and oxygen using electrolysis, powered by solar, wind, or hydroelectric energy. The result is a clean, zero-emission fuel.
The Green Hydrogen Economy
The shift to green hydrogen is central to the automotive industry’s long-term strategy. Automakers are partnering with renewable energy companies to ensure their hydrogen supply is clean. For example, Hyundai has invested in wind and solar projects to power its hydrogen production.
Countries with abundant renewable resources are positioning themselves as green hydrogen hubs. Australia, Chile, and Saudi Arabia are developing large-scale green hydrogen plants for export. These projects could supply hydrogen to regions with less renewable capacity, like Europe and East Asia.
Cost and Scalability Challenges
Despite its promise, green hydrogen is still more expensive than gray hydrogen. Electrolyzers are costly, and renewable energy prices—while falling—still make green hydrogen two to three times pricier than fossil-based alternatives. However, costs are expected to drop as technology improves and production scales up.
Governments are offering subsidies and incentives to close the gap. The U.S. Inflation Reduction Act includes tax credits for clean hydrogen production, making green hydrogen more competitive. The EU’s Green Deal also supports hydrogen innovation with funding and regulatory support.
Policy and Global Collaboration
Government policy plays a crucial role in the adoption of hydrogen technology. Without supportive regulations, infrastructure investments, and financial incentives, the transition will be slow and uneven.
Many countries have introduced national hydrogen strategies. Japan was one of the first, launching its roadmap in 2017. South Korea followed with a comprehensive plan in 2019, aiming to become a global hydrogen leader. The U.S. and EU have since released their own strategies, focusing on clean energy, job creation, and climate goals.
International Partnerships
Global collaboration is accelerating progress. The International Partnership for Hydrogen and Fuel Cells in the Economy (IPHE) brings together 19 countries and the EU to share research, set standards, and promote hydrogen adoption. The Hydrogen Council, a global CEO-led initiative, includes over 100 companies working to scale hydrogen solutions.
These partnerships help harmonize regulations, reduce trade barriers, and align research efforts. They also foster knowledge exchange between developed and developing nations, ensuring that hydrogen benefits everyone.
Local Initiatives and Pilot Projects
Cities and regions are also driving change. Los Angeles has launched a “Hydrogen Highway” initiative to support FCEVs and build refueling stations. The Port of Rotterdam is developing a hydrogen import terminal to supply Europe. In Australia, the state of Queensland is building a hydrogen-powered train for tourism.
These pilot projects test new technologies, build public awareness, and create blueprints for wider adoption. They also attract investment and talent, strengthening the local hydrogen economy.
The Road Ahead: Challenges and Opportunities
The automotive industry’s adaptation to hydrogen technology is well underway, but challenges remain. Cost is still a major barrier. Fuel cells, hydrogen storage tanks, and refueling infrastructure are expensive. While prices are falling, they need to drop further to compete with gasoline and battery EVs.
Energy efficiency is another concern. Producing, transporting, and converting hydrogen into electricity is less efficient than charging a battery directly from the grid. For every 100 units of renewable energy used to make hydrogen, only about 30–40 units reach the vehicle’s motor. In contrast, battery EVs use 70–90 units. This inefficiency means more renewable energy is needed to power hydrogen vehicles.
Safety is also a consideration. Hydrogen is highly flammable and requires careful handling. However, modern storage systems are designed to be safe, with multiple layers of protection and automatic shut-off valves. Accidents are rare, and hydrogen disperses quickly in open air, reducing explosion risks.
Despite these challenges, the opportunities are immense. Hydrogen can decarbonize sectors that are hard to electrify, like aviation, shipping, and heavy industry. It can store excess renewable energy and provide backup power during outages. And it can create new jobs in manufacturing, engineering, and infrastructure.
The Future of Hydrogen in Mobility
Looking ahead, hydrogen is unlikely to replace battery EVs entirely. Instead, it will likely complement them. Battery EVs will dominate urban and short-range transport, while hydrogen will power long-haul trucks, buses, trains, and possibly even aircraft.
Automakers are preparing for this dual future. Many are developing platforms that can support both battery and fuel cell systems. This flexibility allows them to respond to market demand and regulatory changes.
Consumers will also play a role. As hydrogen vehicles become more affordable and refueling networks expand, public acceptance will grow. Education and outreach are key—many people still don’t understand how hydrogen works or its benefits.
In the next decade, we can expect to see more hydrogen models on the road, more stations in cities and along highways, and more collaboration between governments, companies, and researchers. The automotive industry’s adaptation to hydrogen technology is not just about cleaner cars—it’s about building a sustainable, resilient, and inclusive transportation system for the future.
