本論文は、スペインとポーランドを対象に、再生可能エネルギーの余剰電力を利用したグリーン水素および合成燃料の技術的・経済的ポテンシャルを評価した。電力システムの時間別データに基づく独自手法により、利用可能な余剰エネルギー量を定量化し、Power-to-X設備の容量係数を算出。その結果、年余剰エネルギーはポーランド886GWh、スペイン2329GWhとなり、水素製造コストはそれぞれ4.1EUR/kg、2.18EUR/kgと推定された。余剰ベースのPower-to-Xは高再エネ比率の系統で有効だが、余剰の時間的連続性やシステム特性に制約される。

This study assesses the technical and economic potential of using surplus renewable electricity for green hydrogen and synthetic fuel production in Poland and Spain. Using hourly power system data, the authors quantify usable surplus energy and capacity factors for Power-to-X installations. Annual usable surplus is 886 GWh in Poland and 2329 GWh in Spain, with levelized hydrogen costs of 4.1 EUR/kg and 2.18 EUR/kg, respectively. Surplus-based Power-to-X can support high renewable integration but is constrained by surplus availability and temporal continuity.

📄 Abstract（原文）
The increasing share of variable renewable energy sources (RES) in power systems leads to growing challenges related to grid balancing and the management of periodic electricity surpluses. One potential pathway for utilizing these surpluses is their conversion into synthetic fuels via Power-to-X technologies. This study analyzes the technical and economic potential of surplus renewable electricity utilization for the production of green hydrogen and synthetic fuels, using Poland and Spain as representative case studies of power systems with low and high RES penetration, respectively. An original methodology based on hourly power system data was developed to identify technically feasible surplus electricity volumes, accounting for changes in renewable and conventional generation, minimum renewable energy share thresholds, and a minimum two-hour continuous operation requirement. The analysis quantifies both instantaneous and usable surplus energy on an annual basis and evaluates the resulting capacity factors of Power-to-X installations. The results show that the annual usable surplus energy amounts to approximately 886 GWh in Poland and 2329 GWh in Spain, corresponding to maximum capacity factors of about 27% and 50%, respectively. Based on these surpluses and assuming low-cost electricity during surplus periods (10 EUR/MWh), the levelized cost of green hydrogen was estimated at 4.1 EUR/kg in Poland and 2.18 EUR/kg in Spain. The resulting production costs of green methanol reach approximately 739 EUR/Mg for Poland and 378 EUR/Mg for Spain after accounting for avoided CO2 emissions. The findings indicate that surplus-based Power-to-X systems can play a meaningful role in integrating high shares of renewable energy, particularly in power systems with high and stable RES penetration. However, their contribution remains strongly constrained by surplus availability, temporal continuity, and system-specific characteristics.
