Abstract

With the race to decarbonise in full swing how do carbon capture utilisation and storage (CCUS) projects get a head start? This paper explores the journey the Gippsland Basin Joint Venture has gone through to identify and exploit the advantages that its existing infrastructure presents in order to progress world-class CCUS opportunities. Drawing on examples across the full CO2 supply chain it details how re-use of existing infrastructures can achieve positive results in terms of cost, schedule and the environment. Hydrocarbon production from the Bream Field ceased in 2020. Normally this would put the platform and associated infrastructure on the path to decommissioning and removal. Instead Bream will continue to have a bright future storing CO2 supplied via a re-used gas export pipeline. Technical evaluations have considered how to safely handle CO2, what parts of the asset could be re-used, what new kit is required and what should be decommissioned. Powered by a hybrid renewables system the new-look injection platform will be remotely operated storing up to 2 MTA. At the Longford Gas Plant the focus has been how to efficiently capture CO2 in order to meet the requirements of multiple purification plants and the Bream sequestration project. Plant trials and testing have determined how to optimise gas processing for integrated CCUS operations. Opportunities to leverage existing power, utilities and process equipment have been included in design through careful brownfield assessment. Supporting this is a cross-functional team rapidly enhancing their hydrocarbon toolkit with the opportunities that CCUS integration presents.
