Long Term Stewardship: Releasing Residual Liability

Payne Institute Program Director Brad Handler, student researcher Siddhant Kulkarni, and Lindene Patton write the fourth paper in a series of papers on the use of Carbon Capture and Storage (CCS) as a climate mitigation tool envisions the permanent underground storage of CO2. In a carbon geological storage project, the final phase is referred to as Long Term Stewardship (LTS). It follows the Post Injection and Site Care (PISC) phase, i.e., after the injection well has been plugged, the developer has monitored the subsurface for any CO₂ leaks for the prescribed period, and the site has been “closed.” July 29, 2024.
