Leveni & Bielicki (2023): A potential for climate benign direct air CO2 capture with CO2-driven geothermal utilization and storage (DACCUS)

Martina Leveni, Jeffrey Bielicki IN: Environmental Research Letters, DOI 10.1088/1748-9326/ad0924

Here, the authors propose to leverage geologic CO2 storage in sedimentary basin geothermal resources to produce geothermal heat and electricity for the process energy requirements of solid sorbent DACC. This sedimentary basin CO2-driven geothermal utilization (SB-CO2DGU, also known as CO2 Plume Geothermal) circulates some of the emplaced CO2 to extract geothermal heat in a closed loop between the subsurface reservoir and surface geothermal facility. The proposed integration of DACC and CO2-driven geothermal Utilization and Storage (DACCUS) adds CO2 from the air to this closed loop system that produces renewable energy for use in the DACC process.
