This paper proposes an electricity–thermal–hydrogen–gas integrated energy system coupling oxy-fuel combustion capture (OCC), coal-to-hydrogen (C2H), and power-to-gas (P2G). A multi-source hydrogen supply and ladder-type carbon trading with stochastic optimization for wind uncertainty minimize expected total cost. Results show a 7.61% cost reduction and 29.60% carbon emission cut, with sensitivity analysis across energy price scenarios.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では水素・CCUSはGX推進戦略の中核だが、本論文は石炭由来水素を前提とする中国型モデルであり、日本の再エネ由来水素やブルー水素戦略とは前提が異なる。ただし炭素取引とCCUSを組み込んだ経済ディスパッチ手法は、日本の電力・水素政策や企業の脱炭素投資判断に示唆を与える。
In the global GX context
While the paper is grounded in China's coal-to-hydrogen context, its integration of oxy-fuel capture, carbon trading, and multi-energy dispatch offers transferable methodological insights for global hydrogen and CCUS deployment. It contributes to the broader energy-transition literature on cost-effective decarbonization pathways, relevant to ISSB/TCFD-aligned transition planning.

📄 Abstract（原文）
To address the current challenges in hydrogen‐integrated energy systems (IES), such as the single hydrogen production mode, the high cost of traditional coal‐to‐hydrogen (C2H) processes, and the severe carbon emissions from C2H processes, this paper proposes a framework for an electricity–thermal–hydrogen–gas IES based on the cooperative operation of oxy‐fuel combustion capture, C2H, and power‐to‐gas (OCC–C2H–P2G). First, by introducing the synergistic operation of C2H and power‐to‐hydrogen (P2H), a multisource hydrogen supply system is established, effectively improving the overall economy of the system. Second, the OCC system is integrated to significantly curb carbon emissions from the C2H process through its high‐efficiency carbon capture capability, and the oxygen generated by the OCC system is directly used in the C2H process, thereby effectively reducing hydrogen production costs and achieving integrated synergy of “hydrogen production – carbon capture – cost reduction.” On this basis, a ladder‐type carbon trading mechanism is introduced, and a multiscenario stochastic optimization approach is employed to handle wind‐power uncertainty, formulating an IES low‐carbon economic dispatch model that minimizes the expected total system cost. Multicase comparative analysis shows that the proposed model can reduce the total system cost by 7.61% while effectively cutting carbon emissions by 29.60%. Furthermore, sensitivity analysis reveals the influence mechanisms of various key parameters on the low‐carbon economic performance of the proposed model and verifies its comprehensive advantages across multiple energy price scenarios.
