It's very difficult to make a piston engine run on hydrogen.

Really? BMW managed it on a dual fuel production car.

I see they have given up on it too. Wonder why?

Because like all these wonderful ideas it has disadvantages over petrol
and diesel.

It;s wonderful when there is no petrol and diesel.

When there is no petrol or diesel, how are you going to make your
hydrogen? With no fossil fuels, electricity will be much more expensive
than now and it makes no sense to waste that making hydrogen.

I am not an advocate of hydrogen. Most of it is made from natural gas.
You might as well just use the natural gas. This is done in South
America.
Dribble is the hydrogen man.
It could be made by electrolysis but it would be inefficient and
costly.
