 Direct Air Carbon Capture and Sequestration (DACCS) is a carbon negative technology that utilizes solid amine based capture and it has proven to capture carbon dioxide from the air even though content of the air is much lower than of a flue gas from a coal plant.However, it would require renewable energies to power since approximately 400kJ of work is needed per mole of CO2 capture.Furthermore, it is estimated that the total system cost is $1,000 per tonne of CO2, according to an economic and energetic analysis from 2011.
