  1. Re:hydrogen ftw on America's First Pipeline-Fed Hydrogen Fueling Station · · Score: 1

    When pitting an FCEV against a BEV both charged from an electric source, the power plant and motor are the same, so they cancel out. The BEV has a battery (obviously) and transmission line losses, since an electrolysis plant will be located beside the power plant. Each of those are about 95% for about 90% efficiency. The electrolysis of water is about 25 to 40% efficient. Then the hydrogen has to be compressed (85%) or liquefied (60%). Then it has to be piped to a fuel station (90%). Then is has to be converted back into electricity (40 - 50%). That makes 5 - 15% efficiency.

    Converting fossil fuels to hydrogen doesn't.

    CH4 + H2O + heat -> CO + 3H2
    CO + H2O -> CO2 + H2

    Except that batteries are already cheaper, more available and at least 4 times more efficient than hydrogen.

    No one has tried to produce hydrogen on a large scale from solar energy because it's economically infeasible, and will be until fossil fuels cost about 10 times what they do now.

    As soon as you switch to renewables, hydrogen craps its pants. Anything inherently electrical like solar or wind will be 4 times more efficient charging batteries and there will never be enough waste biomass to drive all our cars. Unless you're growing biomass specifically for fuel, in which case you're using a lot more land, water and fertilizers (made from hydrogen) than a few more solar or wind farms.

    you mean centralize fossil fuel burning at a single plant instead of distributing is across thousands of cars.

    Great, now in addition to cracking/steam reforming, liquefying/compressing to 10,000psi, piping/trucking and squeezing it through connectors foolproof enough for the average fool to operate, we have to make millions of tonnes of dry ice, bury it and keep it frozen for the rest of eternity.

    Just charge a battery and be done with it.

    If a tank ruptures the hydrogen quickly escapes in to the air forming a fuel/air explosive instead of sitting around for hours waiting to be ignited.
