"The purpose of this note is to provide basic details of the major large-scale experiments and commercial projects in Europe and elsewhere that demonstrate that hydrogen can fully complement green electricity and will provide the energy source for almost all activities that cannot be electrified. I write because I think that the development of a ‘renewables plus hydrogen’ economy should be the policy priority for the UK and other countries."
Re cement: you can turn cement CO2 NEGATIVE if you use Magnesium Hydroxide to make it which in turn can be produced from sea water while you electrolyse hydrogen.
