Lecture
This lecture covers the concept of Carbon Geological Storage (CGS), focusing on the CO2 cycle, storage facilities, deep geological storage in saline aquifers, mineral trapping, and the hazards associated with capture and separation. It discusses the anthropogenic perturbation of the C cycle, trends in CO2 emissions over time, available capacities, and time scales for carbon storage. The lecture also explores various carbon storage facilities such as atmosphere, oceans, and soil, emphasizing the need for storage close to emission points. It delves into topics like mineral trapping in basalt, seismic hazards, ocean acidification due to CO2 storage, and groundwater quality changes. The lecture concludes with the challenges and research needs in CGS, highlighting the importance of large-scale CCS and CGS initiatives.
