Hydrogen for a pollution free future?

http://80.70.129.162/site/en/weizman.asp?pi=371&doc_id=4210

**Thoughts
Hydrogen may well be the most plentiful element in the Universe.....but do we have enough metallic Zinc to power the World this way?

Or charcoal, which the researchers indicated was also used to create the zinc powder...

Area necessary to generate 1 GW electrical, theoretical minimum

mi^2
Area Modality
=================
1000 biomass
300 wind
60 solar
0.3 nuclear

A watt-hr is a watt-hr. It bears no marker of having been created by burning algae or fissioning uranium. Your electric bill contains that information - abundantly. Nobody cheats on thermodynamics.

Chemical & Engineering News 83(34) 42 (2005) "Filling up with hydrogen" Enviro-whiner crap.

An eldritch hydrogen storage modality holds 53 moles H2/liter at ambient conditions with 36 megajoules/liter recoverable energy overall. Compare with 8 MJ/liter for cryogenic liquid H2 (C&EN published value). DOE's 2010 requirement is 45 kg H2/m^3 storage. This modality achieves more than 100 kg H2/m^3 in 2005.

No storage degradation or generated waste occurs in its 100% recycle during a decade of daily use. National distribution networks are in place. Compatible engines are in commercial production. After you drain your tank of diesel fuel you can refill it within minutes.

Or people could just get off their lazy bottoms and ride bicycles couldn't they.

There is no god given right to drive a Hummer.

I'm not fully conversant with the mathematics that Uncle Al has given in his full reply.
But it does seem to me that Hydrogen stored in whatever form, even a Clathrate, (apart from very dangerous high comression)could never be released in a sufficient quantity to power the modern car, for the length of time and speeds it travels today

Prehaps a simple 15% mixture of Hydrogen mixed with one or more other inert gases and moderately compressed, might power a piston vehicle at a much reduced velocity?
I have lost faith in Hydrogen ever being used neat, as an explosive gas to drive a piston engine. Prehaps a hybrid vehicle using a Hydrogen Cell to produce electricity plus a small simple gasolene engine is the way forward?

Uncle Al makes the false assumption, usually made by those of a more theological persuasion, that science is static and progess is not made.

Fortunately he is incorrect:

I expect that in 1855 Uncle Al would have posted something to the effect that the fastest moving conveyance possible was a horse.
