This analysis builds on the technical accomplishments of the NREL Wind2H2 program by examining the systems required for large-scale production of hydrogen via water electrolysis. By investigating lower cost and cost-optimized electrolysis production systems that use renewable wind energy, this analysis increases our understanding of how to develop green, sustainable hydrogen production systems. The model developed can be configured for different economic and technical parameters, allowing individual production sites and overall wind electrolysis trends to be analyzed.
