The UK is currently constructing a large nuclear power plant. Well, in fact its a French company that's doing the building, and the money is Chinese! The company constructing it has had severe problems in constructing this type of reactor - in fact they haven't actually built a working one yet - and the UK consumer is committed to buying the electricity at an inflated price (About twice that of offshore wind) for 35 years, if it works at all. By the time this idiotic project is finished - if it ever is - it is unlikely to be needed. More and more companies and households are turning to wind or solar or both for their power, and as a result, the demand on the UK grid is steadily falling year on year, and more and more seems to be coming from wind anyway. So it seems to me its output could well be used for hydrogen production. It will be expensive of course as the power produced is grossly overpriced so the Chinese investors can make a profit on their investment, but perhaps it might be able to make hydrogen economically?
