Varying the rate at which carbon dioxide (CO2) is injected into geological storage sites can enhance not just the sites efficiency but also its ability to store the greenhouse gas securely, according to a new study.
A new study by scientists at the University of Edinburgh, one of the founding partners of the Scottish Carbon Capture & Storage (SCCS) research partnership, will be invaluable to developers of carbon capture and storage (CCS) projects in the UK and abroad, where varying injection rates and interruptions are expected to occur over a project’s lifespan due to, for example, CO2 delivery rates from capture sites, pressure management and well maintenance.
The findings suggests that, with every change or interruption to CO2 injection into a geological storage site:
