The HyOrc engine represents a breakthrough in zero-emission heavy goods vehicle (HGV) propulsion technology by combining hydrogen fuel with Organic Rankine Cycle (ORC) technology. The engine uses pure hydrogen and oxygen as fuel, combusted in four precisely engineered pulse combustion chambers at up to 32 pulses per second. This controlled process produces only water vapor, making the system completely emission-free.

The water vapor generated drives a multi-stage inward radial ORC turbine, efficiently converting thermal energy into mechanical energy. HyOrc’s patented turbine design leverages waste heat from combustion to further produce steam in a second stage, significantly boosting power output and overall thermal efficiency, which reaches an impressive 45%—well above conventional internal combustion engines.

The system’s integrated turbocharger captures excess steam to enhance performance, resulting in high torque output ideal for HGVs. With a 244.9 kW (326 HP) capacity, 800 km travel range per refuel, and a payload capacity of 32,000 kg, HyOrc offers a reliable, sustainable solution for commercial transport.

Its manufacturing cost is 20% lower than comparable hydrogen internal combustion engines, eliminating the need for rare earth metals. HyOrc is a cost-effective and scalable option for future heavy-duty zero-emission mobility solutions.
