Battery electric trucks should be the baseline for hydrogen fuel cells electric vehicle (HFCEV) comparisons, rather than any internal combustion engine alternative. Stop comparisons of fill times. In a zero-emission future world, as in California’s plans, diesel does not exist. What is the value of a comparison on fill times?

EU-funded scientists developed a novel 320 kW (429 hp) diesel engine for light helicopters as an alternative to conventional turboshaft engines. Helicopters conventionally employ a turboshaft engine that has a much better power-to-weight ratio compared to diesel engines. The engine weight is the crux of the project.
