The potential for increased water use has often been noted as a challenge to the widespread deployment of carbon capture and storage (CCS) to mitigate greenhouse gas emissions. Early studies, that are widely referenced and cited in discussions of CCS, indicated that installation of a capture system would nearly double water consumption for thermal power generation, while more recent studies show different results. The Global CCS Institute has conducted a comprehensive review of data available in order to clarify messages around water consumption associated with installation of a capture system. Changes in water use estimates over time have been evaluated in terms of capture technology, cooling systems, and how the data are reported.
Guido Magneschi, Institute’s Senior Advisor – Carbon Capture, and co-author of the study, presented the results of the review and illustrated the main conclusions.
