Those other areas are about to move away from diesel.
It's not the miracle solution you may think it is.
At the current state fo technology, it's got serious issues.
I'm not the only one out there struggling with the particulate filter - which may even put out more harmful, but far smaller soot than the black clouds of days gone by.
NOx emissions are still a lot higher than on a petrol engine.
The oil gets more polluted than in a petrol of gas (CNG / LPG) car, making it harder to recycle.
My bet is on methane.
It burns very cleanly - emitting CO2 and water.
Though still mostly a fossil fuel, it can be fairly easily generated in a sustainable way.
It's still cheap to use.
A comprehensive distribution network is readily available - at least in most of Europe.
In a sense it has similar drawbacks to hydrogen (low energy density, needs to be pressurized) but nowhere near as extreme as with hydrogen.
