Hybrid‐energy driven decarbonization transition in cement production: Process modeling and techno‐economic analysis

Abstract As a major contributor to global CO 2 emissions, the cement industry is under unprecedented existential pressure from market contraction and stringent carbon regulations, escalating the need for cost‐effective CO 2 reduction solutions. In response, this study proposes a “Green Loop Cement Plant” concept based on a hybrid‐energy driven cement CO 2 capture and utilization (HE‐CCCU) system. Process modeling and techno‐economic analysis demonstrate that by integrating tail‐end calcium looping with in situ dry reforming of methane, the HE‐CCCU system can achieve a 90% reduction in CO 2 emissions and avoid carbon taxes of 38.73 $/t clinker , with an estimated payback time of 8.01 years. Through hybrid‐energy driven co‐production of syngas and electricity, annual performance evaluations indicate an average daily net income of 241.35 $/t clinker under real solar irradiance and dynamic electricity pricing scenarios. These findings facilitate the decarbonization and techno‐economic transition of cement manufacturing while offering a new pathway for renewable energy deployment in the industrial sector.
