ギリシャのサモトラケ島を対象に、風力発電、海水淡水化、そして水素・揚水・バッテリーの4つの貯蔵構成を組み合わせたハイブリッド再生可能エネルギーシステムの技術経済評価を実施。10年間のシミュレーションにより、完全な自立は可能だが、系統連系を活用し貯蔵容量を抑えることで経済性が最大化されることを示した。
English
This study assesses a hybrid renewable energy system for a Greek island, combining wind turbines, desalination, and four storage options (green hydrogen, pumped hydro, batteries, and a combined option). Based on a 10-year simulation, it finds that full energy-water autonomy is technically feasible, but economic sustainability is best achieved by leveraging grid interconnection and sizing storage below full-autonomy levels.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の離島（例：沖縄・小笠原諸島）でも同様の再生可能エネルギー・淡水化・貯蔵システムの導入が検討されており、本論文の技術経済評価手法は参考になる。また、日本政府のGX政策において島嶼部のエネルギー自立は重要なテーマであり、SSBJやTCFD開示におけるレジリエンス評価にも間接的に寄与する。
In the global GX context
This paper provides a techno-economic framework for integrating renewables, desalination, and multiple storage technologies on islands, relevant to global island energy transitions. For GX disclosure, it highlights the importance of system-level resilience and cost-benefit analysis, which can inform climate risk assessments under TCFD or ISSB frameworks.
👥 読者別の含意
🔬研究者:This paper offers a detailed decade-long simulation of a hybrid renewable system on an island, providing valuable data for energy modeling and storage optimization research.
🏢実務担当者:Energy planners on remote islands can use these results to assess the techno-economic feasibility of combining wind, desalination, and multiple storage options for energy-water autonomy.
🏛政策担当者:Policymakers should note the trade-off between full autonomy and grid interconnection, which is critical for designing cost-effective decarbonization strategies for island regions.
📄 Abstract（原文）
Samothrace is a Greek island in the northern Aegean Sea. Though connected to the mainland grid and demonstrating strong wind potential, it is challenged by seasonal shortages in both electricity and potable water. This study assesses a Hybrid Renewable Energy System designed to meet local energy and water demands while maintaining economic viability. The system consists of 10 wind turbines (23.5 MW), a reverse osmosis desalination plant yielding 876,000 m3/year, and four alternative storage configurations: green hydrogen, pumped hydro, lithium-ion batteries, and a combined green hydrogen–pumped hydro option. Using identical climatic and demand data, system performance was simulated for the years 2011–2020. Wind generation reached 113,000 MWh annually, of which 81–84% was exported to the mainland. Potable water demand was met at a rate of 99% in all scenarios, with monthly production ranging from 17,500 m3 in February to almost 50,000 m3 in August, thus requiring 1.80% of wind output. Investment costs ranged from 34.4 M € to 39.8 M €; net present values remained around 75 M € for all scenarios. Results demonstrate that complete autonomy can be achieved; however, economic sustainability is maximized by leveraging the interconnection and sizing storage below full-autonomy levels.
