I used to think in terms of electrification, sourced from solar, but recently started to analyse the implications of recent developments in Hydrogen Fuel Cell technology... it changes everything. The technology is moving forward rapidly, and presents us with the practical capability of being able to fuelise sunlight at source, after which the fuel, green hydrogen, can do everything we used to do with fossil fuels, but with none of the pollution, and best of all, for free, when all is said and done. https://www.sciencedirect.com/science/article/pii/S266654682100063X
