本研究は、フィンランドの既存風力発電所24カ所のデータを用いて、陸上風力発電による水素生産に必要な土地面積を推定した。変換ロスを考慮すると、政府目標達成には国土の8%以上（耕地面積に相当）の土地が必要となる可能性がある。土地利用の社会的・生態学的影響を考慮した計画の重要性を強調している。
English
This study estimates land area required for onshore wind-based hydrogen production in Finland using empirical data from 24 wind farms. Considering conversion losses, meeting national hydrogen targets could require over 8% of Finland's land area, comparable to arable land. The findings highlight the need for transparent land-use assessments in energy transition planning.

日本のGX文脈において
日本でも水素社会の推進が進むが、陸上風力の適地が限られる中、本論文の土地利用評価手法は参考になる。ただし日本の水素戦略は輸入水素や洋上風力に重点があり、直接的な適用には注意が必要。
In the global GX context
As countries worldwide scale hydrogen production, land-use conflicts with biodiversity and local communities become critical. This study provides a transparent methodology for assessing land requirements, contributing to international discussions on sustainable energy transitions and spatial planning. It underscores the need to prioritize energy efficiency to minimize land footprint.

📄 Abstract（原文）
Abstract Background The transition to low-carbon energy systems is essential for climate change mitigation, but it involves new land use pressures, posing potential risks to biodiversity and local communities. This study estimates the land area required for six onshore wind power-based hydrogen production scenarios in Finland, using empirical data from existing wind power plants. By doing so, it contributes to broader discussions on the socio-ecological impacts of energy transitions. It emphasizes the importance of better understanding and addressing land use pressures affecting ecosystems and communities in decision-making, in an effort to build sustainable, low-carbon societies. Results The analysis is based on 24 wind power areas in Finland, with capacities ranging from 90 to 416 MW. Their direct land use (km 2 ), turbine spacing area (km 2 ), installed capacity density (MW/km 2 ), length of the edge between industrial production sites and their surroundings (km and m/MW), and annual energy production potentials (TWh) were calculated. Using the calculated installed capacity densities and comparing them with the capacity density values obtained from literature, we analyzed the hydrogen value chain from variable wind power production to pressurized hydrogen. Since there are losses at each conversion step, much more wind power, and thus land area, is needed than what the hydrogen output alone indicates. When scaling these findings to fit hydrogen economy scenarios, the land area required for wind power and the infrastructure associated with hydrogen production becomes substantial. To achieve the hydrogen production targets set by the Finnish government using onshore wind power, it might be necessary to install wind power plants covering more than 8% of Finland’s total land area, including the spacing area, a figure comparable to the country’s arable land area. Conclusions These findings highlight the scale of land use change associated with hydrogen production powered by onshore wind energy. Standardized, transparent land use assessments, distinguishing between direct, spacing, and total land use, are needed to understand socio-ecological impacts across scales. Expanding assessments beyond techno-economic considerations and individual projects to landscape scales, along with prioritizing energy efficiency, is essential to aligning renewable energy expansion with socio-ecological sustainability and broader sustainable development.
