    Hydrogen as a fuel

    I read the nuclear power plant thread below and thought of this. Trippledence suggested that France got loads of NPP running, and we should all know our HEPs are under-utilized during the night so they had to pump water back up behind the dam. So, that does mean there are PLENTY of unused electrical energy. They'll end up as heat if not used. But why don't just convert them into Hydrogen. HEPs and NPPs are all located near sea/rivers. Water is already there.

    Literally you just need 2 bottles, 2 electrodes and 2 wires to make hydrogen there. Instead of running a pump which is probably less than 30% efficient, why not change it into hydrogen. You can start producing your own hydrogen with just a few resistors, 2 carbon electrodes and 2 coca-cola bottles, you don't even need a fiver to get all those, but why no company do it in a larger scale?

    We've piped gas from Russia to UK, why not pipe Hydrogen gas instead. Gas is flammable, so do Hydrogen, so the pipes are already fire-proof (or whatever the term is). Instead of buying electricity from like France, why don't we buy Hydrogen gas which don't get lost as heat as if we push electricity across the sea through cables?

    Also for wind energy. No one said you HAVE to charge it in a battery. Charge it into a bottle with hydrogen and use the hydrogen in your boiler

    We could have switched to Hydrogen easily and cheaply but why no one do that?

    Hydrogen is much more volitile than any of the other fuels we use and is best transported as a liquid, which means very cold, therefore expensive.
    I don't mean to sound cold, or cruel, or vicious, but I am so that's the way it comes out.

    Might be an idea to keep it at high pressure... probably cheaper than chilling it..

    If Hydrogen leaks into the air it will quickly rise up into space since its escape velocity is low And even increase the oxygen concentration within the atmosphere LOL. And if its so cheap there is not a problem it leaks. Just transport it in compressed bottles and it should be fine (Very light too)

    Ony problem is a spark blowing you up into space

    Well, if you spark your gest tab you also blow up into space. But infact it discharge into air so quickly and burn so quickly it is actually less harmful than petrol getting on fire.

    that seems liek a good idea yeah, and i remember doing it in chemistry, oddly enough the main reason for the problem agaisnt what your saying is why i remember it, collecting it in two tubes from the elctodes in water, collecting it in bigger and bigger tubes, putting it near the bunsen burner for the pop test, which became the Boom test after peopel tried to get more and more lol

    You're thinking of pumped storage stations like Dinorwig and Ffestiniog. In fact they have a cycle efficiency of over 70%, compared to 40% for hydrogen fuel cells (according to the wikipedia article). Any other hydroelectric powerplant is simply turned on during the day and turned off (or down) at night so the dam can refill. We don't have a great deal of hydropower in the UK anyway.

    So, that does mean there are PLENTY of unused electrical energy. They'll end up as heat if not used. But why don't just convert them into Hydrogen. HEPs and NPPs are all located near sea/rivers. Water is already there.
    I don't know how much unused energy we have, but I don't think it's all that much. Nuclear reactors run cointinuously it's true, but they only provide about 20% of our power, so a combination of Dinorwig and encouraging people to use Economy 7 electricity must mean that little goes to waste in this country.

    Hydrogen as I understand it is not suitable for use in boilers etc. However, having said all that, there is a case for using it as an energy storage system, especially if we increase the amount of renewable power sources like wind and wave which are variable in nature.

    Plus electricity, and that is where the problem lies as well as the fact that it cost a lot as well to make it in the amounts you are saying even using electricity drawn from sorces that are not used that much (such as HEP at night). Also the fact that it needs electricity is a problem unto itsself as what happens when we run out of fossil fuels which make over half our power.

    This point is also true about using hydrogen powered cars yes they themselves may only at some water vapour into the atmosphere making the hydrogen adds a lot more
