That video is missing demand response enabling sector coupling. Take green steel using hydrogen as a chemical feedstock. Oversize the electrolyzers and add some storage and the plant is now able to utilize low prices and leave the firm 10% to more important consumers, while enabling more producers to exist. This without paying the round-trip cost. Almost all studies looking into 100% renewable systems finds them easily possible globally but a holistic approach is required.
