Transformation and Utilization of Wind Power to Hydrogen Energy

Abstract

The accelerated global warming has prompted countries to commit to carbon neutrality (take the Paris Agreement as an example), and hydrogen energy has emerged as a crucial alternative to fossil fuels. With the global renewable energy sector booming, wind and solar power generation continues to expand. However, the widespread curtailment of wind and solar power has led to significant waste of clean energy resources. Converting excess electricity from these sources into hydrogen has emerged as a crucial approach to manage surplus power and optimize energy structures. This paper systematically examines the current status of wind-solar curtailment, provides detailed analyses of core conversion technologies including alkaline water electrolysis and proton exchange membrane (PEM) hydrogen production, and thoroughly evaluates technical, economic, and policy challenges in this field. Targeted development strategies are proposed to offer comprehensive guidance for advancing the hydrogen production industry utilizing wind-solar curtailment technologies.
