A change in thinking about energy needs to happen to truly understand why Wind and Solar and a bit of storage is enough. You have to accept that at times there will be overproduction of power because storing it to hit exact use capacity isn’t cost effective. Some storage makes sense, but its much cheaper to have more capacity.
What I think will happen in the future once we reach the point this is how most energy comes is more people will be on Octopus like smart energy schemes where you might get paid for using electricity and there will be companies that use this to remove CO2 from the atmosphere. We are approaching a world of energy excess but only at certain times and there are opportunities to use that energy for the right reasons to reverse the damage we have done with CO2 emissions.
