For the next decade, we should concentrate on building out grid-scale storage to soak up the surplus energy available when the sun is shining and the wind is blowing. Green hydrogen is the likely the next best use, as it will in turn enable things like direct reduction of steel.

If we get to the point where we can reliably expect 8-12 hours of free electricity 80% of the time, then things like Direct Air Capture of carbon become viable - but that's likely 25-30 years off, so who knows what other technologies will have appeared in the meantime.
