Fate of CO2 and other Gases emitted at the Seabed (WP3)

WP3 will undertake process studies and model evaluations to underpin risk and impact assessments of potential leaks from CO₂ storage sites into the overlying waters. Natural CO₂ seeps, as analogues of storage leakage, will provide a detailed database on the processes involved.

Objectives:

• To understand CO₂ transport mechanisms and biogeochemical transformations in the water column.
• To develop appropriate monitoring methods to quantify CO₂ leakages in the water column, detect precursors of CO₂ leakage, and test different instruments for their sensitivity, reliability and cost effectiveness.
• To develop a simulation framework necessary for risk/impact assessment
• To develop best practices for monitoring baseline surveys of oceanic waters for fingerprinting CO₂ leakage to the overlying water column, using data from both the natural analogues and existing CO₂ storage sites.
