本論文は、石炭火力とCCS、再生可能エネルギーを統合したエネルギー生産ユニット（IEPU）において、Power-to-X（P2X）技術ルートを技術経済的に最適選定するフレームワークを提案。アルカリ電解＋メタン合成が最適とされるが、電力・炭素価格変動に収益性が敏感であり、リスク管理の重要性を示す。
English
This paper proposes a decision framework for selecting optimal Power-to-X (P2X) technology routes in integrated energy production units combining coal-fired power, carbon capture, and renewables. Using levelized cost of hydrogen and conversion revenue as metrics, it identifies alkaline electrolysis plus methane synthesis as best for a 600 MW coal retrofit, but warns of high sensitivity to electricity and carbon price fluctuations, requiring risk management.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、石炭火力のアンモニア混焼や水素転換が議論されているが、本論文はCCSを組み込んだP2Xルートの経済性評価手法を提供しており、SSBJの情報開示における移行計画策定の参考となる可能性がある。
In the global GX context
For global GX, this paper provides a systematic techno-economic comparison of P2X routes for coal-fired power decarbonization, relevant to transition finance and ISSB-aligned disclosure on transition plans. Its integrated risk assessment under carbon price volatility is useful for investors assessing fossil-to-clean strategies.

📄 Abstract（原文）
In pursuit of energy decarbonization and supply security, the integrated energy production unit (IEPU) is regarded as a notable multi-technology energy production model integrating coal-fired power, carbon capture, and renewable energy. As a core component of the IEPU, Power-to-X (P2X) technology encompasses various technical routes with distinct economic performance and technological maturity at different development stages. Thus, selecting the most techno-economically optimal route is critical. In view of this, this paper proposes an integrated decision-making framework for the selection of P2X technology routes in IEPU, which combines “technology selection—economic analysis—risk assessment”. Firstly, a decision model for key P2X processes is established, with the levelized cost of hydrogen and unit hydrogen conversion revenue as core performance metrics to identify the optimal technology combination for hydrogen production and utilization. Secondly, integrating the aforementioned optimized technical route, a life-cycle economic benefit evaluation model is constructed for IEPU retrofit projects to systematically assess the overall economic feasibility of the IEPU project. Thirdly, an investment risk assessment model for P2X-integrated IEPU retrofits is established based on interval number theory, which can quantify project risks under fluctuations of critical parameters such as electricity and carbon prices. Finally, a case study of a 600 MW coal-fired unit retrofit demonstrates that “alkaline electrolysis + methane synthesis” constitutes the optimal P2X technology combination. However, its profitability is relatively sensitive to fluctuations in external market parameters, necessitating the implementation of corresponding risk management strategies.
