I will challenge your assertion that energy storage is some kind of “deterministic barrier” that needs to be crossed before decarbonizing our grid. Solar is still negligible in terms of penetration in many places in the world (even though it and wind are the cheapest new build primary energy today, so expect this to rapidly change). As well, you can add quite a bit of solar to a grid before curtailments become necessary. Add that solar and wind pair together (when it’s not sunny, it’s often windy and visa versa). Many grids today (Uk, Denmark, Germany, etc) can have decent penetration of renewables with 0 energy storage. Add in large scale grid interconnectivity (sunny in Nevada, windy in Idaho, Hydro in pacific north west) it will always be sunny and windy somewhere.
