It is good for Norway, cuz they have an excess of hydropower. Also Denmark, with an XS of geothermal energy from Iceland. But, for most of the world, it is just a sop for the auto and oil industries, similar to corn ethanol for ADM, Cargill, and Monsanto. Why do you think Shrub promotes it? Not for our benefit. energyandcapital.com theoildrum.com Another example of the disconnect between the researchers and reality is their proposed quantity and method of hydrogen production. Their most optimistic (smallest) quantity of hydrogen required is 239 billion kg/year (see Table 1), which they propose to produce from renewable electricity via electrolysis. The quantity of electricity required (at 100% efficiency, no less) is a staggering 9810 billion kWh/year2; this is nearly 2.5 times current annual US electric production. (Worse than that, it's roughly 6-10 times what it would take to power all ground transport directly with electricity3.) ===== Over and above these issues of cost, hydrogen infrastructure...essentially, it is the poor efficiency of the Hydrogen FC route that dooms it... as Engineer-Poet frequently points out: why go Electricity > hydrogen > fuel cell > electricity > motor 50% 80% => 40% efficiency When you can go: Electricity > battery > motor => 90% efficiency The only reason that fuel cell vehicles gained prominence for the last decade was because batteries didn't seem to be "up to the job". Now that new Li Ion battery technologies are close to market (A123 Systems etc)... that has all changed again... theoildrum.com
