Are hydrogen trains the way forward?

Last year a hydrogen-powered train travelled on Britain’s rail network with the aim to start carrying passengers by the end of 2021. What are your thoughts on hydrogen technology, key considerations, or risks? Comment below to share your thoughts!

  • H2O2 is a slightly stressed molecule, and regrouping

    as

    H2O2  >> H2O  + O

    twice so really


    2 (H2O2) >> 2 H2O  +O2  is less stressed, so a bit exothermic, the bottle fizzes like lemonade and gets a bit warm.


    If you warm it up, or add a catalyst (platinum nickel or others) then it goes off more like the icing sugar in your beer experiment and unlike the beer it gets really quite hot (try the sugar trick in in someone else's beer to make enemies quickly). 

    In a confined space this can generate enough heat to boil some of the water created to steam, and the steam and the oxygen give some propulsion. It is not that great.in terms of energy per volume of fuel.


    But  far better is to use the O of the


    H2O2  >> H2O  + O


    to generate oxygen in the middle of a real fuel (petrol, methane, hydrogen)  where the oxygen meets a carbon or another hydrogen and creates loads of heat in the process.

    Unlike normal burning where the oxygen is only getting in at the outside surface of the fuel, properly mixed this can give an instant burn throughout, so lots of energy may be released more or less explosively - great for launching rockets, less of a good thing in engines, where rarely do you want it all to burn at once.
