Our energy platform brings hydrogen to applications where battery-electric drives reach their limits: high continuous loads, long operating hours and limited charging infrastructure. The approach is retrofit-first. Vehicles, machines and vessels are kept, and only the drive system is exchanged.

Typical applications

• Off-road: airport ground support equipment, intralogistics and heavy-duty forklifts, special and municipal vehicles, other machinery with high duty cycles
• Maritime: hybrid ferries and car ferries, car ferries, onboard power generation

Maritime concept: hydrogen-hybrid ferry retrofit

Existing ferries are retrofitted rather than rebuilt. The diesel engines are replaced by electric motors, while the propulsion units, hull and superstructure remain unchanged.

• Energy concept: A traction battery is charged overnight from shore power. Hydrogen engine-generators recharge it during the day as needed.
• Operation: Port manoeuvres run on battery power alone, so they are emission-free.
• Infrastructure: One shore power connection and a compact hydrogen refuelling station are sufficient. There is no fast charging at the landing stages and no tank container swapping.

Key benefits

• Near-zero emissions: no CO₂ emissions in operation, very low NOx
• Higher efficiency: substantially higher tank-to-shaft efficiency than diesel engines running at low part load
• Robust technology: combustion engine know-how enables maintenance through existing service networks
• No hydrogen quality requirements: compatible with varying hydrogen qualities
• Low acquisition costs compared to fuel cell systems, with a significantly longer service life of the energy converter
• High continuous power and power density for demanding load cycles
• Fast refuelling using existing 350-bar infrastructure
• Retrofit-capable: cost-efficient conversion of existing vehicles and vessels
