本論文は、再生可能エネルギーの出力抑制電力を利用したグリーン水素による重要負荷復旧の枠組みを提案。ドミニカ共和国の事例分析により、25トン水素貯蔵モジュールが30MWの重要負荷に対して6時間および12時間の復旧を完全にカバーし、重要未供給エネルギーを60.2%削減できることを示した。また、復旧電力により年間43.5ktCO2の排出回避が可能と推定。
English
This study proposes a planning framework for using green hydrogen produced from curtailed renewable electricity for critical-load restoration. Applied to the Dominican Republic power system, a 25 t H2 storage module fully covers 6h and 12h restoration windows for a 30 MW critical load, reducing critical energy not served by 60.2% during a 24h event. Recovered electricity could avoid 43.5 ktCO2/year.

📄 Abstract（原文）
Green hydrogen is commonly assessed as a renewable fuel or long-duration storage option, but its value as a critical-load restoration resource remains less developed, particularly when produced from curtailed renewable electricity. This study develops a planning-oriented framework to assess green hydrogen for critical-load restoration by linking renewable curtailment, proton-exchange membrane electrolysis, hydrogen storage, fuel-cell reconversion, critical Energy Not Served (ENS) reduction, economic valuation, and carbon-footprint savings. The framework is applied to the Dominican Republic power system as a representative insular case with rapid renewable expansion and limited flexibility. Using monthly preliminary real-operation reports from OC-SENI, the reference case considers 196.46 GWh/year of curtailed non-conventional renewable electricity in 2025, producing 3.78 kt H2/year and 65.5 GWh/year of recoverable electricity. Under the reference screening assumptions, a 25 t H2 storage module would provide 433.29 MWh of usable electricity, fully covering 6 h and 12 h restoration windows for the 30 MW illustrative critical-load case and reducing critical ENS by 60.2% during a 24 h event. The recovered electricity could avoid 43.5 ktCO2/year under the SENI combined-margin grid-displacement case, with higher avoided operational emissions under the diesel-backup displacement sensitivity.
