That's an excellent bit of consultancy by KPMG, but the problem is in the small print, where you need green H2 production. 'Cadent' (formerly called 'British Gas') the main monopoly on the gas infrastructure in the UK are in the business of keeping their existing infrastructure going, and installing the gas mains to homes (i've just had my old metal gas mains changed to HDPE yellow plastic ones - cost £6K - but 100% covered by a qualifying local government grant, hence why I got it done). So, I'm a bit skeptical of the monopoly infrastructure controller paying a private consultancy to tell us what the best options are (even if they disguise it as from another institution) - however, using the existing infrastructure makes sense, though leaves several issues unanswered: the main one being, who's going to pay for me to replace a £1,500 boiler with a likely £10k fuel cell one when the monopoly tell me they are turning off the gas?!
Not sure this is part of a plan to convert all of the UK at this stage (would have to go through UK government bill), but more of a discussion around one potential part-solution. Their calculations and assumption are likely only 'accurate until proven inaccurate', but I dare say that currently, we may have to beef up our armed forces a tad following this spy poisoning, deal with Brexit, and address the chronic lack of homes we have blissfully and ignorantly drifted in to. Would be good to see this more extensively trialed in some new housing development towns and see what it's like before they send over the letter advising that my taxes are gong up 10% and the gas is being turned off! Still... there is that thing about getting the hydrogen out cleanly, and then being able to use it affordably at the other end - as well as them being able to keep rather than scrap their aged network of gas pipes.
I'm also trying to assemble an argument here where you may need gas and H2 supply, and one pipe won't suffice... though I suppose the intention would be a phased roll-out on a regional basis... so that may not be such an issue.
That bit about home H2 compression is quite interesting - you could potentially see the issue of loads of hydrogen vessels on every street, but maybe you only need a small amount of storage for the next day of use... I don't currently understand how much would be needed, but I see a washing machine sized appliance that topps off the car and feeds the boiler, containing a few Kgs of hydrogen.
I don't doubt that the nuclear age will slowly become the hydrogen age - I am mostly convinced about that, especially the way geopolitics are going at the moment - so it's a case of 'yes do it, but don't make my life even more miserably expensive than it already is while doing it'. Lastly, the future proposals (in general) do seem to revolve around more localised grid solutions, and that is probably a good thing for continuity and efficiency of power delivery. The UK has more wind than the rest of Europe combined - I can't understand why we are not installing wind generators wholesale at the moment - it's not that hard these days.
