本研究は、セメント工場の排ガスからCO2回収・有効利用（CCU）とグリーンアンモニア製造の代替ルートを技術経済的に分析した。CO2回収（90%効率）と貯蔵が最も経済的だが（109 €/トン）、全排ガス放出（22 €/トン）には及ばない。将来的には高付加価値化学品の合成経路統合により経済性が向上する見込み。
English
This study performs a techno-economic analysis of alternative routes for carbon capture and utilization (CCU) and green ammonia production from cement plant flue gas. Currently, CO2 capture (90% efficiency) and storage is the most economical route at 109 €/tonne of flue gas, but still uncompetitive compared to full emission (22 €/tonne). Future integration of high-value chemical synthesis pathways is expected to improve economic feasibility.

📄 Abstract（原文）
The manufacturing industry is the second largest emitter of CO2, with the cement industry being one of the main contributors (7-8 % of the global emissions). Carbon capture and utilization (CCU) technologies are promising decarbonization solutions for the cement industry, addressing both fossil fuel-related (40 %) and process-derived emissions (60 %). Within a cement plant, producing synthetic natural gas (SNG) from captured CO2 is particularly suitable, as it is sufficient to fully replace solid fuels in the rotary kiln. On the other hand, the use of zero-carbon fuels, such as green ammonia, is also recognized as a promising approach for decarbonization. In this work, a superstructure was developed to explore alternative routes for producing SNG and green ammonia from CO2 and N2 in cement plant flue gas, respectively. The routes were modelled in Aspen Plus® V14, and their economic viability was assessed. Currently, the most promising route, at a cost of 109 €/tonne of flue gas, involves CO2 capture (90% efficiency) and storage, with the N2-rich stream emitted. However, all the routes remain uncompetitive compared with the full emission of the flue gas (22 €/tonne). Routes for green ammonia production from N2 in flue gas were compared with those from atmospheric air but were found to be uncompetitive. Nevertheless, with future developments, the economic feasibility of integrating pathways for synthesizing high-value chemical products into the cement industry is expected to increase.
