Gemini members are part of several research projects. Some examples are given below:

• REALISE demonstrates a refinery-adapted cluster-integrated strategy to enable full-chain CCUS implementation.
• LAUNCH focuses on understanding and controlling degradation.
• ALIGN-CCUS interlinked carbon capture, utilisation and storage research with the goal of transforming industrial regions into economically robust, low-carbon centres.
• NCCS is large Norwegian CCS research center.
