Interesting, also sulphur cycle and CO2 electrolysis, which may be enhanced in efficiency with solar thermal as its an endothermic reaction, are ways to do this also. A closed cycle can be envisaged by binding CO2 in the oxidation step to CaO, which releases more heat.

Now we only need an application where long term storage is needed (hint: for a grid based 100% on PV and wind it isn’t)

Another blow for fossil fuels 🤙🏾
