Adoption of Cluster Based Sequestration Strategy for Realizing Net Zero Carbon Emission

Abstract

The COP26 climate summit came to a close with renewed global commitments and focused efforts on reducing carbon emissions, aimed to close the gap to limit global warming to 1.5°C. The 1.5°C limit has been projected by scientists as the line in the sand, beyond which the global warming effects would be catastrophic. It is therefore critical, that a comprehensive and integrated strategy is implemented to ensure effective carbon reduction solutions are applied for a sustainable future. Carbon Capture and Storage (CCS), if well planned and implemented effectively, has the potential to help reduce the amount of CO2 emitted to the atmosphere. When lining out plan for CCS, the analysis covers the following factors: the source and gathering, the capture technology, transportation method and sequestration site selection. This paper proposes a structured process in examining the above and more importantly focusing on clustering of sequestration site to derive an impactful CCS strategy. This cluster-based strategy will enable monetization of high CO2 fields via a more sustainable development. Systematic screening and selection process ensures the best technologies and development concept were selected during this study. As CO2 sequestration is non-revenue generating, clustering several sequestration developments will allow for CAPEX and OPEX sharing between fields.
