A study in @ScienceMagazine shows wind & solar in just 1% of coastal waters could generate 22 PWh/yr — nearly all global electricity. However

The role of offshore wind and solar PV resources in global low-carbon transition
Offshore wind and solar PV could meet nearly 30% of 2050 electricity demand using only 1% of suitable ocean areas.

Sure. But as soon as a solution is "on the list" we should be able to do a feasibility assessment similar to that we did for CCS here.

That's true, but neither of those can support negative emissions or contribute in other niche CCS applications. So we need CCS even if all renewables and related tech develop astronomically fast.
