Promoting the Carbon Removal in Coal Utilization-A Benefit-Risk Analysis among Full-Chain Carbon Capture and Utilization Project
2015
Zhu, Lei | Liu, Xin
The full-chain development of CCUS (Carbon Capture, Utilization, and Storage) requires the cooperation of different stakeholders. Focusing on full-chain CCS-EOR (enhanced oil recovery) projects, this study presents a benefit-risk analysis for two kinds of stakeholder (power plant owner and oil field owner). Their interaction (in CO₂ capture and utilization) will be reflected in the contract design, in terms of several items referring to price setting and cost sharing. Taking account of uncertainty factors and operational flexibility, benefits and risks for a power plant and an oil field cooperating on a CCS-EOR project can be separately evaluated. The simulation results show that the oil field occupies the dominant position in cooperative CO₂ utilization, and that contract design needs to improve the position of power plants, especially in terms of the pricing power of captured CO₂. The present approach can help different stakeholders in the CCS value chain to better identify their level of benefit and risk, and to support the negotiation of cost and risk sharing among different stakeholders in full-chain CCS deployment.
