    Hydrogen Boilers

    Hydrogen Boilers 14th Jun 19 at 2:49 PM
    AIUT - from 2025 no new gas boilers are to be installed and by 2050 we will have to rip out any remaining units.

    New boilers will have to be powered by Hydrogen - do we take a backward step and have to buy Hydrogen in canisters like we do with Calor ?

    Hydrogen cyclinders I believe are currently available from the likes of Air Products or whatever they are called these days, and they are heavy.

    Could be that every property fitted with a hydrogen boiler will also have an electrolysis unit as well to extract the hydrogen from water, and use the separated hydrogen/oxygen mix as fuel for the boiler.

    There's not much room in modern houses for cylinders - I grew up in the 1950's with two (one on, one standby) calor cylinders and they had a cupboard all to themselves.

    How big might a electrolysis unit be ?

    Presumably the gas pipes we use today that transport primarily methane to our homes, that formally transported town gas to our homes (a mixture mainly of hydrogen , methane & carbon monoxide) can be used to transport hydrogen to our homes.

    Most, if not all, existing gas boilers could actually run on hyrdrogen today, although I doubt many gas boilers today will be around in 30 years time even if there was no change.

    Makes you wonder how the hydrogen will be generated, and also if domestic boilers are going to be banned, what about the gas boilers - which are a thousand or more times the size of domestic ones - which are currently used in power stations to provide the steam to turn the generators providing electrical energy, will they nalso be replaced at end of life?

    Wonder if the powers that be are looking at the setup on the Scottish island - the name escapes me at the moment - which uses wind energy to do the electrolysis and bottle the hydrogen and some bright spark wants to introduce it throughout the country.

    Could be another ill-thought costly government enterprise which we all end up paying for.

    The current proposal is to build hydrogen production facilities and use the existing mains gas network.

    Just as when mains gas replaced town gas changes will be needed to gas appliances.

    What about commercial set ups ? Domestic boiler are about 30kw - Commercial 250Kw ?

    Commercial premises are supplied by mains methane, they will therefore be supplied with mains hydrogen.

    Power stations?


    It's simple... They will generate electricity, which is used to electrolyse water into hydrogen, part of which is used to run the power station.


    If I sound mad suggesting, what amounts to perpetual motion, how mad does the government sound to be laying this down as law?

    72% of the entire universe is Hydrogen but we got given a planet where all of ours is in water.

    Milk bottle sized, daily delivery's by a milk float.. i mean a Hydrogen float.


    Or the next Gov just push it to 2040.
