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.
