Study on the Water-Saving Potential of Renewable Energy Hydrogen Production in the Yellow River Basin from the Perspective of Water Footprint

日本語

黄河流域の各省における再生可能エネルギー水素製造の水フットプリントをライフサイクル理論に基づき評価し、節水可能性を定量化。技術比較と地域差を分析し、水資源制約下での水素産業発展への示唆を提供。

English

This study constructs a bottom-up water footprint evaluation model for renewable hydrogen production based on life cycle theory, quantifying water-saving potential across provinces in the Yellow River Basin. It compares technologies and regional differences, offering insights for sustainable hydrogen development under water constraints.

日本のGX文脈において

日本では水素戦略が進むが、水資源制約はあまり注目されていない。本論文は水素製造の水消費を定量化する手法を提供し、日本の水素サプライチェーン構築や地域資源計画に応用可能。

In the global GX context

Globally, hydrogen is a key decarbonization pathway, but water footprint is often overlooked. This paper provides a life-cycle framework to assess water use in renewable hydrogen, relevant for regions facing water scarcity and for integrating water considerations into hydrogen policies.
