There are other methods of sequestration that may be better than carbon capture. Rock weathering is the main one, where dump crushed olivine rock into the oceans where it picks up the dissolved CO2. This has advantage that uses known technology and scales well. It also locks CO2 into rock instead of worrying about where to put the captured CO2.
