The FP6 project CO2ReMoVe aims at creating a scientifically based reference for the monitoring and verification of CO2 geological storage. Through extensive R&D into monitoring, measurements and verification on multiple storage sites, CO2ReMoVE wants to prove the long term reliability and safety of geological CO2 storage and provide the R&D necessary for monitoring and verification leading to guidelines and standards for policy makers, regulators and industry. This is useful for CO2 storage to qualify in emission trading schemes.
