Carbon capture and storage? Not a help yet
A debate has been smouldering on about what role, if any, “Carbon Capture and Storage” (CCS) technologies should play in ecological transition. CCS denotes chains of technology for capturing carbon from the chimneys of factories and power plants. The chimney is fitted with solvent filters, which much of the CO2 dissolves into — CCS’s coal industry proponents claim up to 90%. For storage, the solvent is then pumped to somewhere where it is heated up, forcing the CO2 out again, where it is stored, perhaps underground. A small amount may be used for fizzy drinks, in greenhouses for plants, and...
