Electricity storage has long been the problem and no doubt we will continue to make progress, but hydrogen stores the power of electricty, being made by electricity but delivering its stored power by combustion. The real issue is capacity. renewables have made massive inroads into the electricity capacity, but the needed capacity is going to have to trable to replace petrol, diesel and domestic gas over the next couple of decades.
Higher building standards and the retrofitting of old houses and flats with better insulation and draught proofing, particularly in the private rented sector, remains the most cost effective quick win, but unfortunately our present government messed up its programme to do this spectacularly.
