Re: It's not just the storage
It's just so much easier to use hydrocarbons for storage and almost certainly cheaper as well. AFAIK reduction of CO2 to CO and thence to CxHyOH or CxHz still looks the most likely route but is getting much less funding. Currently, it's cheaper to do this electrically which would lead to massive arbitrage / fraud, but probably no less than we already have with the Great Biofuel Swindle; and it does look like it might be able to do this below cost and thus turn all those renewable generators into storage depots.
