The trouble with hydrogen is that it takes energy to extract it

describe this as "zero emission".

Of what though?

It may not save CO2 emissions locally but removes other more nasty stuff to
a remote place where it can be cleaned up more easily - some gain to local
residents at least?

It would of course be simpler and cheaper simply to burn the methane in
an IC engine. But it would also be less politically correct and harder
to pull the wool over the eyes of the travelling public.

But wouldn't there be more dirty stuff emitted locally?
