Although the world’s governments have tentatively agreed to attain net zero greenhouse gas (GHG) emissions by 2050, it will take time to switch from fossil fuels to renewable alternatives. Therefore energy transition strategies are evolving to use existing and emerging low or zero carbon technologies to achieve decarbonisation goals. Carbon capture, transport, utilisation and storage (CCUS) are the cornerstones of GHG reduction, so integrating CCUS with repurposed existing petroleum infrastructure may lower costs of change and delay decommissioning spend during energy transition. Hydrogen (H2) could play a major role in delivering a net zero future, but there are significant challenges in using petroleum sector pipelines, infrastructure, and fields for H2 operations. This course provides a framework to evaluate the suitability of soon-to-be abandoned offshore oil and gas networks and depleted reservoirs for the transport and storage of CO2 or H2. The pros and cons of utilising CO2 for enhanced oil recovery (EOR) are debated. The potential risks to be mitigated vs. the potential cost savings available from enacting a repurposing strategy are assessed, and the various proposed CCS business models are compared. Finally, the need for an appropriate, coherent and consistent reporting system for CO2 transport, utilisation and storage is discussed.
