286 kilojoules of energy is released per mole of hydrogen burned.

In a tank at room temperature, hydrogen is a supercritical fluid, because the critical point is 33K. 


In a tank, a long as the tank is strong enough, the pressure could be any value up to at least 10,000 psi, but at high enough pressure it would solidify.
