I really wish that is true but I seriously doubt it. Although my country made a hard shift into renewables (hydro, wind and solar, more recently) to the point we have had entire days when those sources alone can provide the necessary energy to run the country, while fully deactivating coal centrals and only maintaining on or two gas powered, storage hasn't been a great concern, unless we count green hydrogen as such, with a plant to be built somewhere in the near future (or not).
