本研究は、低炭素移行における材料制約が再生可能エネルギーシステムの性能と回復力に与える影響を評価する。ボトムアップのエネルギーシステムモデルを用いて、2026年から2050年までの気候政策経路をシミュレーションし、技術展開と材料要件を結び付ける。結果、炭素価格政策は再生可能エネルギーと貯蔵の展開を加速するが、材料需要とサプライチェーン露出を増加させる。排出制約政策は貯蔵拡大と材料使用を緩和し、輸入依存を減らしてエネルギーセキュリティを向上させる。

This study assesses how material constraints affect renewable energy system performance and resilience during low-carbon transitions. A bottom-up energy system model simulates pathways from 2026 to 2050, linking technology deployment to material requirements. Results show carbon pricing accelerates renewables but increases material demand and supply-chain exposure, while emission constraints moderate storage and material use, improving energy security despite lower renewable penetration.

📄 Abstract（原文）
This study assesses how material constraints influence the performance and resilience of renewable energy systems during low-carbon transitions. A bottom-up energy system model is used to simulate the evolution of the energy system including photovoltaic, wind, solar thermal, battery storage, and hydrogen technologies along with fossil-fuel based technologies under alternative climate policy pathways from 2026 to 2050. Material requirements are explicitly linked to technology deployment, allowing consistent evaluation of resource extraction, imports, and system-level impacts. Energy security is assessed using a set of indicators covering technology performance, material availability, economic conditions, primary energy scarcity, and environmental outcomes, that are aggregated into a composite index. Results show that carbon pricing policies accelerate renewable and storage deployment but significantly increase material demand and supply-chain exposure. In contrast, emission constraint policies moderate storage expansion and material use, reducing import dependence and improving overall energy security despite lower renewable penetration. The findings highlight the importance of material-aware planning for renewable energy systems and provide practical insights for designing sustainable and secure energy transition pathways.
