本論文は、2030年のイベリア半島の再生可能エネルギー拡大計画に伴う出力抑制と電力価格低下を分析し、系統接続型再生可能水素製造の可能性を評価。空間分解能を有する電力モデルを用いた結果、理論的には最大547ktpaの水素生産が可能で、セラミック・ガラス産業の天然ガス消費の20-92%を置き換え可能と試算。しかし、実際の水素バレー計画容量に制限すると、余剰電力を活用しても生産量は35ktpa未満となり、大規模産業脱炭素化への寄与は限定的と結論。
English
This paper analyzes planned renewable expansion in the Iberian Peninsula for 2030, focusing on curtailment and low electricity prices for grid-connected hydrogen production. Using a spatially resolved power model, it finds theoretical potential up to 547 ktpa of hydrogen, replacing 20-92% of natural gas in ceramic/glass industries under EU ETS. However, when limited to actual hydrogen valley capacities and local curtailment, production drops below 35 ktpa (<2% of potential), making large-scale industrial decarbonization unlikely.

日本のGX文脈において
本論文はイベリア半島の系統連系型水素製造の可能性を評価。日本でも再生可能エネルギー拡大に伴う出力抑制問題があり、余剰電力による水素製造の理論的ポテンシャル評価手法は参考になる。ただし、実際の水素バレー計画に基づく制約を考慮すると大規模効果は限定的という結論は、日本の水素戦略にも示唆を与える。
In the global GX context
This study assesses grid-connected renewable hydrogen from curtailed power in the Iberian system, offering a methodology that can be applied to other regions with high renewable penetration. It highlights the gap between theoretical potential and practical constraints of hydrogen valley capacities, which is relevant for global hydrogen strategy and industrial decarbonization under EU ETS.

📄 Abstract（原文）
The planned expansion of the Iberian renewable power system for 2030 is expected to increase curtailment and reduce electricity prices favouring affordable grid-connected renewable hydrogen production. Results obtained with a spatially resolved power model confirm substantial renewable energy expansion and curtailment levels (7.7-35 TWh), that theoretically could produce up to 547 ktpa of hydrogen and replace 20 to 92% of the natural gas consumed by the region’s EU ETS-covered ceramic and glass industrial facilities. However, when limiting conversion to local curtailment and planned capacities at the hydrogen valleys, even with supplemental production during periods of low electricity prices (<20 €/MWh), this potential becomes marginal (below 2%). Therefore, despite potentially increasing operation rates at hydrogen valleys, with current planned capacities, the production supported on these conditions (<35 ktpa) is unlikely to provide a viable pathway for large-scale industrial decarbonization.
