Whilst I appreciate discussing H2 in the context of its use to replace diesel and petrol as the primary fuels for transport is OTT for the EVDL, I think it is worth knowing why it will never work and consequently why 'we' should not be wasting our time, energy, brain power and money in researching it - or at least not in preference to a much more realistic alternative... such as EVs.
Araoa's post made me look more into H2 than I already have and in doing so, whilst specifically trying to discover the energy used in compressing H2 to the standard 350 and 700 BAR pressures used (700BAR = 10,000psi), I came upon an interesting document that I would encourage anyone with an interest in EVs to read... http://publications.jrc.ec.europa.eu/repository/bitstream/111111111/6013/1/EUR%2020995%20EN.pdf Unfortunately it is rather dry but if there was sufficient interest I would be willing to précis it - tho I can't promise to be very unbiased.
