本論文は、ガラス製造におけるCCUとパワー・トゥ・ガス技術を統合した閉炭素循環プロセスを提案。技術経済モデルにより、スコープ1排出の99%以上、スコープ1+2の62%を削減可能だが、コストは高く、CO2削減コストは€1,132/tと試算された。経済性は電力価格に大きく依存する。
English
This paper proposes a closed carbon cycle for glass manufacturing via CCU and power-to-gas. A techno-economic model shows over 99% of scope 1 and 62% of scope 1+2 emissions can be abated, but at high cost: CO2 abatement cost estimated at €1,132/t. Economic viability is highly sensitive to electricity prices.

📄 Abstract（原文）
The glass industry faces significant challenges in achieving carbon neutrality due to its reliance on fossil fuels and process-related CO2 emissions from raw material decomposition. While most defossilization efforts focus on CO2-neutral heating, batch-related emissions remain largely unaddressed. This study investigates a closed carbon cycle approach for glass manufacturing by integrating carbon capture and utilization (CCU) with power-to-gas technologies. The proposed process captures both combustion- and batch-related CO2 emissions and converts them into synthetic natural gas using renewable hydrogen. The techno-economic model, based on a typical oxy-fuel container glass furnace (300 t per day) and current (2022) German market conditions, covers all key process steps: flue gas cleaning, CO2 separation, hydrogen production via electrolysis, and methanation. Results show that more than 99 % of scope 1 emissions and about 62% of scope 1+2 emissions can be abated. However, the process is associated with high energy demand and costs, with energy supply alone amounting to €559 (2022) per metric ton glass at an electricity price of €60 per MWh. The cost of CO2 abatement is estimated at €1132 (2022) per metric ton. While all process steps are based on established industrial technologies, the overall economic viability remains highly sensitive to electricity prices and further technological improvements. The approach is especially relevant for high-quality glass production with low cullet content and in regions with abundant renewable electricity.
