Prospective environmental burdens and benefits of fast-swing direct air carbon capture and storage.

Direct air capture (DAC) in combination with storage of CO can lower atmospheric CO concentrations. This study investigates the environmental impact of a new fast-swing solid sorbent DAC system, including CO transport and storage, over its life cycle, using prospective life cycle assessment. This DAC technology is currently on technology readiness level 5 and is expected to operate on an industrial scale by 2030.
