The Future of Hydrogen Fuel Cell Vehicles

While battery electric vehicles (BEVs) dominate the headlines, hydrogen fuel cell electric vehicles (FCEVs) are quietly gaining traction. Toyota, Hyundai, and BMW are all investing heavily in hydrogen technology, and the UK government has committed over £500 million to hydrogen infrastructure. For forward-thinking garage owners, understanding hydrogen is worth your attention — even if the volume of FCEVs on UK roads remains small for now.

A fuel cell vehicle is essentially an electric vehicle that generates its own electricity on board. Here is the simplified process:

1. Hydrogen storage — Compressed hydrogen gas is stored in high-pressure tanks (typically 700 bar) within the vehicle.
2. Fuel cell stack — Hydrogen is fed into the fuel cell, where it reacts with oxygen from the air in an electrochemical process.
3. Electricity generation — The reaction produces electricity, which powers the electric motor. The only by-product is water vapour.
4. Buffer battery — A small battery stores energy from regenerative braking and supports peak power demands.

The result is a vehicle with the range and refuelling convenience of a petrol car (300-400 miles range, 5-minute refuel) but with zero tailpipe emissions.

The hydrogen vehicle market in the UK is small but growing:

• Toyota Mirai — The most common FCEV in the UK. Second-generation model offers 400-mile range.
• Hyundai NEXO — A hydrogen-powered SUV with a 414-mile range and 5-minute refuelling.
• Hydrogen commercial vehicles — Wrightbus is producing hydrogen-powered buses for UK cities, and companies like Tevva are developing hydrogen commercial vehicles.

There are currently around 15 public hydrogen refuelling stations in the UK, with plans for significant expansion. The government's Hydrogen Strategy targets a network of 100+ stations by 2030.

FCEVs share many components with BEVs, so much of the transition applies equally:

• Electric drivetrain — FCEVs use the same electric motors, inverters, and power electronics as BEVs. EV training covers these components.
• High-voltage safety — The same IMI EV safety qualifications apply. High-voltage procedures are identical.
• Conventional wear items — Tyres, brakes, suspension, steering, and cabin filters all need servicing just like any vehicle.
• Hydrogen-specific systems — Fuel cell stacks, hydrogen storage tanks, and hydrogen supply lines require specialist knowledge. This is currently dealer-only work, but will open to independents as the vehicle population grows.

The industry is divided on whether hydrogen or battery electric will dominate:

• Hydrogen advantages — Faster refuelling (5 minutes vs 30+ minutes for fast charging), longer range, better suited to heavy-duty applications (trucks, buses, construction equipment), no rare earth mineral dependency.
• Battery advantages — More efficient overall (battery is 70-80% efficient vs fuel cell at 30-40%), established charging infrastructure, lower running costs, wider vehicle choice.

The likely outcome is coexistence: BEVs for passenger cars and urban commercial vehicles, hydrogen for long-haul trucks, buses, and specialist applications. Both will need servicing.

You do not need to invest in hydrogen capability today, but you should be aware and ready:

1. Get EV qualified first — IMI EV qualifications are the foundation for both BEV and FCEV work.
2. Stay informed — Follow industry developments through the IMI, Society of Motor Manufacturers and Traders (SMMT), and automotive trade publications.
3. Monitor local infrastructure — When hydrogen refuelling stations open near you, FCEV customers will follow.
4. Build diagnostic capability — Ensure your diagnostic tools support FCEV models as they are released.

The garages that thrive through every technology transition are the ones that stay informed and adapt early. ashdub supports all vehicle types in your management system — ICE, BEV, and FCEV — with dedicated service templates for each powertrain type.
