I work in cleantech, and the smart people working on carbon capture and conversion (Opus12, etc.) are assuming renewable prices will drop to the point where they can use excess power to run the catalyst reactions needed.
Unlike the grid, carbon capture power doesn't need to be dispatchable. So you don't need to worry about the intermittemcy of solar and wind.
The same strategy is true for water desalination. They can run the plants whenever there is cheap power.
