本研究は、インドネシアのスンバ島を対象に、浮体式小型モジュール炉（SMR）と再生可能エネルギーを統合したハイブリッドシステムの長期実現可能性を評価する。2060年までの計画期間で、再生可能エネルギー・化石燃料移行シナリオと原子力・再生可能ハイブリッドシナリオを比較し、後者は再生可能エネルギー比率をほぼ100%に高め、化石燃料発電を約87.9%削減し、電力コストを21.9から16.3セント/kWhに低減することを示した。
English
This study evaluates the long-term feasibility of integrating floating small modular reactors (SMRs) with renewables for isolated islands, using Sumba Island, Indonesia, as a case. Comparing a renewable-fossil transition scenario with a nuclear-renewable hybrid scenario to 2060, the hybrid pathway raises renewable share to near 100%, cuts fossil generation by ~87.9%, and lowers electricity cost from 21.9 to 16.3 US cents/kWh, offering a reliable and competitive decarbonization route.

📄 Abstract（原文）
Remote and isolated island power systems face persistent barriers to deep decarbonization due to heavy fossil-fuel dependency, renewable energy intermittency, and limited operational flexibility. This study develops an integrated system modelling and assessment framework to evaluate the long-term feasibility of nuclear–renewable hybrid energy systems for isolated islands, using Sumba Island, Indonesia, as a representative case study. Two development pathways are comparatively assessed over a planning horizon extending to 2060: a Renewable–Fossil Transition Scenario based on solar photovoltaic (PV), battery energy storage systems (BESS), and gas-engine generation, and a Nuclear–Renewable Hybrid Scenario integrating floating small modular reactor (SMR) technology alongside renewable energy and storage. The framework couples hourly operational dispatch, generation expansion planning, techno-economic analysis, reserve margin evaluation, and sustainability assessment. The renewable-transition pathway remains structurally dependent on gas-engine generation, with the renewable share declining to 15.61% by 2060. Integrating floating SMR technology from around 2043 raises the renewable share close to 100% in several years, reduces fossil-based generation by approximately 87.9%, and lowers long-term electricity cost from 21.9 to 16.3 US cents/kWh. The findings indicate that combining floating SMRs with renewable energy and storage offers a reliable, competitive, and sustainable decarbonization pathway for isolated island systems.
