The Guardian - 24/03/11

The much-heralded 'hydrogen economy' never appears to get out of first gear. Are our politicians failing us by not pushing harder for hydrogen-powered cars?

Article continues ...

Lots of interesting comments.

Quentin strolls in.

Portable H2-maker that you can plug in when too much wind is blowing, and use to fill White Vans with H2...

Whoopeeee! A haversack of grants from the government, who were also able to rescue Northern Rock. Where does the electricity come from to make the hydrogen, and when a nuke goes bang, will there be enough hydrogen available for everyone to drive out of the exclusion zone? It sounds too much like BAU.

Or am I too cynical?

If it's just public vehicles, being driven on H2 made from wind energy made during the night when we're all asleep (erm once there are enough WTs to do that), then perhaps a few of the H2-stations are worth having?

The Government will have to push cars sooner or later -- people won't be able to afford the fuel to make them work conventionally.

Then again, Cameron, Osborne and all their horsey landed gentry chums will be alright...

I thought hydrogen has a negative EROEI doesn't it? That being the case, though it may well be worthwhile cracking hydrogen for specialist applications (welding,/cutting etc), it makes no sense as a fuel for a mass fleet of vehicles. It would be more energy efficient to consume the energy used to crack it (electricity, usually) directly in such vehicles.
