Large-scale geologic CO 2 storage (GCS) can be limited by overpressure, while geothermal energy production is often limited by pressure depletion. We investigate how synergistic integration of these complementary systems may enhance the viability of GCS by relieving overpressure, which reduces pore-space competition, the Area of Review, and the risks of CO 2 leakage and induced seismicity, and by producing geothermal energy and water, which can defray parasitic energy and water costs of CO 2 capture.
