US DoE on Hydrogen

Quote :

Storing enough hydrogen onboard a vehicle to achieve a driving range of greater than 300 miles is a significant challenge.

And an interesting comparison with petrol WRT energy content.

Quote :

On a weight basis, hydrogen has nearly three times the energy content
of gasoline (120 MJ/kg for hydrogen versus 44 MJ/kg for gasoline).
However, on a volume basis the situation is reversed (8 MJ/liter for
liquid hydrogen versus 32 MJ/liter for gasoline). On-board hydrogen
storage in the range of 5-13 kg H₂ is required to encompass the full platform of light-duty vehicles.

I want to find out how they propose to produce all this hydrogen.

Enough reading here to keep you up all night.

Increase your H2IQ

Watching Who Killed the Electric Car? would be a good start to denting anyone's faith in hydrogen as a way out of our driving obsession; then, a read of The Last Oil Shock by David Strahan.

Then, on yer bike!

david, I watched the trailer on youtube, it looks good, I will certainly try to get a look at it. May be an Amazon job, I doubt Xtravision will have it.

I also looked up David Strahan, which led me Here , Strahans website.
Plenty of reading for me there.

I'm neither pro or con hydrogen cars yet, I am not informed enough to take either side.

I got the feeling from the trailer that it was the oil interests that killed it ?

Just before Christmas Ecogeek had a report on carbon-neutral hydrogen production using rotting plants




http://www.ecogeek.org/content/view/1171/69/


One of the researchers is reported as saying

When they added 0.2 volts into the mix, hydrogen gas was produced.
Admittedly the amounts produced were very small, but the efficiencies
here are large and they are quick to point out that "this process
produces 288 percent more energy in hydrogen than the electrical energy
that is added to the process."

That's a mental amount more in Hydrogen energy than in electrical energy and they must be comparing it with other "dirtier" sources of electricity..

I think the 288% is the output energy capacity compared with the input electrical only. Most of the energy is coming from the biomass, the electrical energy only seems to be providing a catalyst of some sort.

Anyone seen a Sinclair? Thatcher's crazy besottedness with enterprise blinded her to the folly of driving a partly pedal-driven noddy car down the M1.
In retrospect, I think he was on to something, but they would need to use cycle lanes rather than motorways.
