Interesting! Here's a quote from an abstract by Freund, published in 1998:

"The kinetics of the H2/H2O emission shows that the olivine crystal under study contain interstitial H2 molecules which can diffuse out."

Reference: An Unlimited Hydrogen Source in Igenous Rocks? (http://www.agu.org/cgi-bin/SFgate/SFgate?&listenv=table&multiple=1&range=1&directget=1&application=fm98&database=%2Fdata%2Fepubs%2Fwais%2Findexes%2Ffm98%2 Ffm98&maxhits=200&=%22U32A-31%22)

More info as I can find it...

1000 L of H2/m3 of rock. Hm. That suggests we're going to be looking for ways of crunching a lot of rock in the next ten years or so. Watch for plutonium futures to take off. There will also be a lot of former petroleum engineers retraining in petrohydrogeny...new word, there. Looks nice.

Great link! Thanks.

Studies by the team of common rock types such as granite and olivine have revealed extraordinarily high levels of trapped hydrogen. Professor Freund said that his team had "tantalizing evidence" that as much as 1,000 litres of hydrogen may be trapped in each cubic metre of rock.
1000 liters (or litres if you prefer) = 1 m*3 @ STP (standard temperature & pressure)
=> 1 m^3 of rock contains 1 m^3 of hydrogen.
Neat trick. Seems to me that if there is that much hydrogen in rock, throwing a piece of granite into a fire could be hazzardous to your health.
