Energy Hub based Electricity Generation System Design for an Offshore Platform Considering CO2-Mitigation

Abstract Environmental friendly development is one of the core tasks of future offshore oil or gas projects. Considering the significant CO 2 emission generated by the electricity generation system of offshore oil and gas fields, this paper, based on Energy Hub concept, presents a multi-objective optimal model taken CO 2 -mitigation and operation cost control as objectives, which constructs coupling formulation and constraints about energy flows and CO 2 emission flows. The proposed approach is verified by an existing platform and the result shows that CO 2 -tax will play a decisive role in the future emission mitigation of offshore oil platform.
