高温CO2共電解による化学品・航空燃料製造のサプライチェーンを欧州域で2025〜2050年にわたり最適化モデルで評価。最適構成は合成ガス需要地への併設が有利で、小規模分散型が2030年までに大規模集中型を凌ぐ可能性を示す。ただしe-SAFは高コストで航空需要を満たせず、高価値化学品への戦略的展開が示唆される。

This dissertation evaluates the supply chain for high-temperature CO2 co-electrolysis in Europe from 2025 to 2050 using a spatially explicit optimization model. Results show that co-locating electrolyzers with syngas demand is optimal, and small-scale decentralized systems can outperform large-scale centralized ones by 2030 by avoiding grid fees and using local renewable electricity and biogenic CO2. However, e-SAF production remains costly and cannot meet aviation demand, suggesting a strategic focus on high-value specialty chemicals in geographic hotspots.

📄 Abstract（原文）
Abstract: High-temperature CO 2 co-electrolysis is a promising technology for defossilizing the chemical and aviation sectors. However, successful industrial implementation requires integration into the supply chain. By moving beyond the plant-centric research, this dissertation evaluates the supply chain for CO 2 electrolysis within a European context from 2025 to 2050. By using a spatially explicit supply chain optimization model and a sizing and operational model, CO 2 electrolysis is evaluated at different scales (9-900 MW) for chemical and fuel synthesis applications. The results demonstrate that the optimal supply chain configuration favors co-locating electrolysis plants with syngas demand. While integrating CO 2 electrolysis with carbon capture and storage (CCS) infrastructure could reduce the cost penalty of intermittency, it requires storage strategies such as batteries and temporary intermediate storage. Moreover, small-scale decentralized electrolyzers could outperform large-scale centralized systems by 2030; this advantage comes from avoiding grid fees by connecting directly to local renewable electricity and distributed biogenic CO 2 sources. However, this e-SAF production route remains costly and cannot meet the large demand of the aviation sector. Consequently, strategic development during technology scale-up should target high-value specialty chemicals in geographic hotspots where renewable electricity potential overlaps with distributed biogenic CO 2 sources.
