- jandrese 9y agoThe problem is that you need a big heavy tank to keep all of the Hydrogen molecules from escaping, especially if you're keeping it under pressure. Hydrogen is much more problematic to work with.
- scrooched_moose 9y agoBut look at energy per volume [1]: Diesel: 35.8 MJ/L Hydrogen: 9.17 MJ/L at 700 bar (10,000 psi). It will require a tank of 4x the volume for the same energy which comes with many additional challenges. Plus, a tank that can withstand 700 bar will have to be extremely strong and heavy which hurts your energy/mass ratio. 1. https://en.wikipedia.org/wiki/Energy_density#Energy_densities_of_common_energy_storage_materials https://en.wikipedia.org/wiki/Energy_density#Energy_densitie...
