Two thoughts on this:
Good progress is being made on the clean electricity generation front. But distribution and storage are huge challenges. CO2 utilization processes solve distribution and storage challenges.
Many CO2 capture processes need heat, not necessarily electricity. That really changed the landscape of effective energy sources (e.g. nuclear looks ~3x cheaper per thermal kWh vs. per electric kWh according to a researcher I spoke to). Solar thermal also starts to look practical (and for many processes the energy intensive sorbent regeneration step, unlike the air contractors, is not capex constrained so you don’t really care that it only runs when the sun is shining.
