I think biochar is a CCS technology that works right now, and could be deployed/encouraged at vast scale. Small-scale farmers char their agricultural wastes rather than just burning it (perhaps in simple earth kilns) and bury it in their fields, capturing carbon, and improving the soil at the same time.
