EU加盟24カ国の2025年の時間別電力・太陽光発電データを用い、水素貯蔵による太陽光出力の平準化を分析。平均総合効率54.38%と試算する一方、必要水素貯蔵容量57.4Ggは地質貯蔵の潜在量を超え、長期貯蔵の欠如が実装の主な障壁と指摘。
English
Using hourly electricity and solar data from 24 EU countries in 2025, this study analyzes hydrogen storage for solar output smoothing. It estimates a mean overall efficiency of 54.38%, but required hydrogen storage capacity (57.4 Gg) exceeds geological potential, highlighting long-term storage as a key bottleneck.

📄 Abstract（原文）
Seasonal energy storage as compressed hydrogen offers a potential solution to balance the power grid as intermittent renewable energy sources are expected to increase in capacity due to decarbonization efforts in developed countries. Public hourly electricity production data and hourly solar electricity production data from European Union member countries in 2025 were used for statistical analysis and optimization of hydrogen energy storage, focusing on the optimal share of solar electricity storage needed to achieve a constant energy output from solar power. Equipment sizing for hydrogen units was also estimated. Variations in the round‐trip efficiency of hydrogen energy storage were tested for Italy. The combination of wind and solar electricity production with hydrogen storage integration to produce a constant power output was studied for Germany. Although the round‐trip efficiency of hydrogen energy storage was assumed to be 40%, the mean overall energy efficiency of solar power utilization throughout 2025 for the 24 selected European Union member countries was 54.38%. The mean hydrogen storage capacity would be 57.4 Gg, which greatly exceeds the potential for geological hydrogen storage. Therefore, the main bottleneck for implementing this vision stems from the lack of long‐term hydrogen storage potential.
