Abstract

To achieve China’s ‘dual carbon’ goals, the synergistic development of carbon capture, utilization, and storage (CCUS) and hydrogen energy has emerged as a critical pathway for deep emission reductions in hard-to-abate industrial sectors. This study focuses on the economic implications of integrating CCUS and hydrogen energy systems, and a multi-objective optimization model is developed, encompassing hydrogen production, carbon capture, pipeline transportation, underground hydrogen storage, and hydrogen refueling station deployment. The results indicate that the net present value of the integrated system reaches 19.992 billion CNY, demonstrating substantial economic feasibility. Enhanced oil recovery (EOR) constitutes the primary revenue source, generating 18.794 billion CNY, which accounts for 71.81% of the system’s total revenue. Cost analysis reveals that infrastructure investment represents approximately 32.86% of total costs, while operation and maintenance expenses related to CO₂ account for 47.84%. In contrast, the hydrogen subsystem contributes less than 1% to overall costs, highlighting the significant cost advantage of large-scale hydrogen utilization. Furthermore, the study finds that after 2037, hydrogen storage facilities are expected to play an increasingly pivotal role in hydrogen spatiotemporal allocation. Eventually, this research provides a theoretical foundation and decision-support framework for regional planning and policy formulation regarding CCUS–H₂ integrated systems.
