  • In-house tool for CAPEX and OPEX calculations

 


Projects

Projects

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.
