1 - Biomass Energy Carbon Capture and Storage is usually expressed as 'BECS'. Biomass Carbon Capture and Storage would therefore be BCCS/BCS 2 - Lackner's cold process works for air, so should work just fine for CO2 rich stack emissions 3 - Shipping costs - Why not use steam trains that burn corn cob? 3 - Sinking - why not wrap up in big nylon sacks with rocks in to make them sink. This should discourage bottom-feeders, too.
