This study proposes a solar-attribute-aware scheduling framework for CSP-TES integrated energy systems, embedding a solar-thermal attribute state in TES balance to track solar-derived heat amid hydrogen-recovered and CO2-capture heat. It quantifies green-certificate-eligible CSP generation under coordinated carbon and certificate trading. Validation on a 50 MW system in Northwest China shows 31.49% lower operating cost and 47.13% lower net CO2 emissions.

📝 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・非化石証書と炭素排出取引の連動設計が議論されており、太陽由来熱の属性追跡は証書会計の透明性向上に示唆を与える。SSBJや有報での再エネ調達・排出量開示の精緻化にも寄与しうる。
In the global GX context
As ISSB and CSRD push for granular renewable attribution and Scope 2 accounting, this paper's solar-attribute tracking offers a methodological template for certificate-eligible generation in hybrid energy systems. It also informs the design of coordinated carbon and green-certificate markets, relevant to global transition finance.

📄 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 coordinated carbon emission trading and green-certificate trading 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.
