Liebherr has announced its first crawler excavator powered by a hydrogen combustion engine, the R 9XX H2. The engine is based on an intake manifold injection technology, also known as PFI. Liebherr says that after extensive testing, the results showed strong potential for hydrogen propulsion and off-road applications. The prototype had the same overall performance as its diesel engine counterpart in terms of power output, engine dynamics and response.
