Hydrogen Repowering

We strongly believe that internal combustion engines (ICEs) will remain the most appropriate power source for many applications for years to come and we're pioneering hydrogen powertrain solutions for commercial vehicles.

With over three decades of engineering innovation, we specialise in repowering diesel trucks and buses to zero-emission hydrogen operation - offering a practical and commercially viable pathway to fleet decarbonisation without compromising performance, payload or productivity.

Driving Zero-Emission Transport Today

Our flagship technology, the H2 ICE (Hydrogen Internal Combustion Engine) solution, enables fleet operators to convert diesel vehicles to run entirely on hydrogen fuel. This approach provides operators with an immediate route to achieving zero-emission transport, rather than waiting for new vehicle technologies and infrastructure to mature.

The company’s demonstration vehicle - a DAF LF220 equipped with a 6.7-litre, six-cylinder engine, developed in partnership with MAHLE Powertrain - clearly demonstrates how existing heavy-duty vehicles can be rapidly adapted to operate on 100% hydrogen. This conversion avoids the high cost, complexity and infrastructure delays typically associated with battery-electric or fuel-cell vehicles.

Performance without Compromise

The H2 ICE technology offers a number of key advantages for depot-based and long-haul operators:

• Lower total cost of ownership (TCO) compared with battery-electric or fuel-cell alternatives
• Impressive performance for longer duty cycles and heavier payloads
• Zero-emission operation, allowing access to low and zero-emission city zones

Metier’s comprehensive TCO modelling framework, developed over more than two years and validated with data from active fleet operators, provides an evidence-based assessment of hydrogen’s commercial viability. Unlike basic vehicle price comparisons, this model incorporates all lifecycle costs - from purchase and servicing through to fuel, infrastructure, taxation and residual value - offering operators and investors a clear, realistic pathway to cost-parity with diesel.

If you're a fleet operator who's actively seeking a fast and effective decarbonisation strategy, we can offer the solution. Talk to us about our hydrogen repowering solution.
