CSPと蓄熱(TES)を基盤とする統合エネルギーシステムにおいて、TES放熱に太陽由来熱と水素・CO2回収由来の非太陽熱が混在する問題に対し、太陽熱属性を追跡する状態変数を組み込んだ低炭素スケジューリング手法を提案。グリーン証書適格なCSP発電量を定量化し、炭素排出量取引とグリーン証書取引を連動させる。中国北西部の50MW級システムで検証し、運用コスト31.49%減、純CO2排出47.13%減を達成した。
English
This study proposes a solar-attribute-aware scheduling framework for CSP-TES integrated energy systems where TES discharge mixes solar and non-solar heat from hydrogen conversion and CO2 capture. A solar-thermal attribute state tracks the solar-derived heat share to quantify green-certificate-eligible CSP generation under coupled carbon and green certificate trading. Validated on a 50 MW renewable-rich system in Northwest China, it cuts operating cost by 31.49% and net CO2 emissions by 47.13%.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では再エネ証書(J-クレジット・非化石証書)と炭素市場の連動設計が議論されており、太陽熱属性の追跡手法は証書会計の透明性向上に示唆を与える。CSPは国内導入が限定的だが、蓄熱・水素・CO2回収の統合運用モデルは産業部門の脱炭素計画に応用可能。
In the global GX context
As ISSB and CSRD push for granular renewable attribution, this paper offers a method to track solar-derived heat in hybrid storage systems, improving the integrity of green certificate accounting. It also demonstrates how carbon and certificate markets can be co-optimized, relevant to emerging disclosure frameworks on energy attribute claims.

📄 Abstract(原文)
In integrated energy systems (IESs) based on concentrated solar power (CSP) with thermal energy storage (TES), recovered heat from hydrogen conversion and carbon dioxide (CO₂) capture can improve thermal flexibility, but it also complicates the attribution of CSP generation because TES discharge may contain both solar-derived and non-solar heat. To address this gap, this study proposes a solar-attribute-aware low-carbon scheduling framework for CSP-TES-based IESs. TES is modeled as a multi-source thermal hub that receives solar heat, hydrogen-cycle recovered heat, and high-temperature heat recovered from electrolytic molten carbonate (EMC)-based electrochemical CO₂ capture. A solar-thermal attribute state is embedded in the TES balance to track the solar-derived heat share during charging, storage loss, and discharge. This tracked share is used to quantify green-certificate-eligible CSP generation under coupled carbon emission trading (CET) and green certificate trading (GCT) mechanisms. A 50 MW-class renewable-rich IES in Northwest China is used for validation. Compared with the baseline, the integrated configuration reduces total operating cost and net CO₂ emissions by 31.49% and 47.13%, respectively. The results indicate that the proposed framework improves CSP certificate accounting consistency while coordinating recovered heat utilization, hydrogen conversion, and EMC-based CO₂ capture in low-carbon system operation.
