It doesn't mention whether this changes the power/torque output of the engine which is a big consideration for diesel engines
> "At mining sites, where hydrogen is piped in, we can convert the existing diesel engines that are used to generate power," says Prof. Kook.
> "In terms of applications where the hydrogen fuel would need to be stored and moved around, for example in a truck engine that currently runs purely on diesel, then we would also need to implement a hydrogen storage system to be integrated into our injection system.
