The Hygrogen Fuel engine that BMW are throwing millions at is a far

to produce and not a fossil fuel.
No heavy batteries to crat about (with dubious life)
They already have concepts up and running ... filling time at pump is
very fast, and the liquid hydrogen is stired in what sound like a
sponge, and is safer than petrol in the event of a collision.

Knowing BMW it will have a HUGE price penalty, as just about
everything is an extra (and very expensive extra at that)

Overall hydrigen will be even more polluting than diesel. The power
stations that make teh electricity that makes teh hydrogen have to burn
something

How is the hydrogen made? It needs more energy in than you get out of it..

How will it be transported? Stored?

It may be the de facto aviation fuel in 50 years time, but its a nono on
the roads.
