A Process for Capturing CO2 from the Atmosphere

(Joule 2, 1573–1594; August 15, 2018) In the originally published version of this article, Table 3 listed values for “Engineering” as $127.0M and $76.2M for “Early Plant” and “Nth Plant” scenarios, respectively. These values have been corrected online to $135.2M and $78.0M to match the engineering study from which Table 3 was drawn. All other values in Table 3 remain unchanged, and the summations are now correct. The authors regret this error. A Process for Capturing CO2 from the AtmosphereKeith et al.JouleJune 7, 2018In BriefFirst direct air capture paper for which all major components are either drawn from well-established commercial heritage or described in sufficient detail to allow assessment by third parties. Includes energy and materials balances, commercial engineering cost breakdown, and pilot plant data. When CO2 is delivered at 15 MPa, the design requires either 8.81 GJ of natural gas, or 5.25 GJ of gas and 366 kWhr of electricity, per ton of CO2 captured. Levelized cost per t-CO2 from atmosphere ranges from 94 to 232 $/t-CO2. Full-Text PDF Open Access
