Assessment of sub sea ecosystem impacts

Topic(s): Carbon capture use and storage (CCUS), CO₂ storage

One of the key elements required before receiving permission to commence underground storage of CO₂, will be the ability of the operator to predict the behaviour of the injected CO₂ and demonstrate a thorough understanding of the risks of leakage, and the associated impacts of these leaks. Also, CO₂ Capture and Storage (CCS) operators must be able to demonstrate that CO₂ can be injected into suitable storage reservoirs both safely and with minimal or no environmental impact. The safety aspect predominantly relates to good design and operational practices and strict adherence to accepted health and safety procedures.

This study aims to assess the extent of information currently available on the effects of CO₂ seepage on subsea ecosystems, and assess what gaps in knowledge exist, along with providing recommendations for further research to address these gaps.
