Enter H2 EVs.

Enables the continued use of petrol station networks and supply chains, by providing an extremely high kw/kg fuel.

Compressed H2 gas used with fuel cells is the green future of heavy industries.

Its less efficient than Electricity, but beats Diesel, Jet fuel and conventional petrol by far.

The only major issue is that H2 has a horrible kw/m3 value compared to other fuels.

For example, using an A320 aircraft, not only will the wings need to be filled with the fuel, as they are now, but about 20-40% of the cargo hold as well to reach the same range. That being said I did these calculations while ignoring the massively increased range from using a lighter fuel, which may even it out in the long run.

For vehicles, using the full engine bay plus additional tanks under the floor/on the roof, with a fuel cell underneath the floor can provide enough volume of H2 gas to match diesel range in a 2.3t Toyota Troopy. Again, not accounting for additional range from reduced weight.

Semi trucks using H2 already exist via conversions, which allow them to continue running AC while idle, which makes truckers much more happy.

H2 has enough energy potential to be a practical fuel, while also being available for 5 min refuelling via service stations with either supplied or produced H2. (Localised production of H2 with local water and electricity would be optimal to reduce the reliance on long distance supply chains.)
