最適化モデルを用い、系統用蓄電池が電力部門のみならずサプライチェーン全体の排出削減に寄与することを示す。ネットゼロ移行初期は短時間蓄電池、後期は中長時間蓄電池が重要となる。気候変動により2050年GB系統コストは50気候年で390億ポンド変動し、送電増強と多時間スケール蓄電池の協調配備が不可欠と結論づける。
English
Using optimisation-based power system models, this thesis shows grid-scale storage cuts both electricity-sector and supply-chain emissions. Short-duration storage dominates early net-zero transition, while medium/long-duration storage grows critical at high renewable penetration. Climate variability drives a £39bn spread in 2050 GB system cost across 50 climate years, requiring coordinated transmission expansion and multi-timescale storage.

📄 Abstract（原文）
The transition to low-carbon power systems requires increasing integration of renewable energy, which introduces significant variability and uncertainty into power systems. Grid-scale energy storage is widely recognised as a key technology to enhance system flexibility, support renewable integration, and improve system resilience. However, the system-wide impacts of storage remain uncertain, and the roles of storage under dynamic transition and climate conditions across temporal and spatial scales are poorly understood.This thesis investigates the role of grid-scale energy storage in low-carbon power systems from system impacts, transition dynamics, and climate resilience perspectives through optimisation-based power system models. The results show that storage deployment can not only decrease emissions of the electricity sector but also reduce economy-wide emissions from the supply chain, indicating that strategic storage deployment acts as a foundational pillar for multi-sectoral carbon budget compliance. In the early stage of the net-zero transition, short-duration storage plays a dominant role, while at the end of the net-zero transition, medium- and long-duration storage becomes increasingly important to address intra-day fluctuations and longer periods of variability as renewable penetration increases. Future climate variability results in a £39 billion difference in the cost of the 2050 GB power system across 50 climate years. The climate-induced spatiotemporal imbalance requires coordinated deployment of transmission expansion and multi-timescale storage. A climate-resilient 2050 GB power system should therefore combine high-density offshore renewables, strategic nuclear baseload, widespread battery, targeted long-duration hydrogen infrastructure, and heavily reinforced transmission corridors into a portfolio that stays close to the low-cost frontier in normal climate years while reducing exposure to extreme climate events.These findings provide a comprehensive understanding of grid-scale storage roles from system impacts to transition dynamics and climate resilience, offering insights for power system planning and energy policy in the net-zero transition.
