Hydrogen is a battery.
It's a means to store energy made elsewhere by the consumption of fuel.
The advertising point that it only emits heat and water vapor (A GREENHOUSE GAS!!!!) is bunk.
The energy to extract hydrogen from whatever chemical you're using costs energy. Costs as in you get less energy out of the hydrogen created than it took to make it.
Well, you get water vapor, heat and smug from your car.
You get whatever pollution is associated with making electricity to crack the hydrogen too.
Before you try to say solar and wind don't make pollution, remember that it takes energy and pollution to MAKE solar and wind generators. Those two technologies are already energy sinks and net polluters.
Years ago, I studied silicon epitaxy (building electronic circuits using a silicon substrate - up to and including solar cells) during my university days.
ReplyDeleteThe lecturer was a leading figure in photo-voltaic cell design - aka solar cells.
He had a bumper sticker on his car that read:
Nuclear NOT solar.
I think that says all that need be said about the "renewable energy" hysteria.
