Using CTL’s sophisticated combustion control the hydrogen engine eliminates NOx emissions, generates zero particulates and attains high levels of thermal conversion efficiency. This is achieved whilst providing performance similar to an equivalent conventional engine. Engine products are now available in the sub 10kW range with larger output engines in development.

This technology is now being used as part of a hydrogen generator trial with solar and battery storage in Orkney. Further early adopter applications in high profile infrastructure projects are under discussion.

To facilitate the adoption of hydrogen powered equipment, CTL is already developing a hybrid gas engine that will allow an early switch to LPG from red diesel and a phased move to 100% hydrogen as the associated infrastructure and security of hydrogen supply develops. Tests on the hybrid engine commence in 2022.
