Summary/Abstract: This paper analyses the global project database on hydrogen production from the International Energy Agency (IEA), comprising 1477 projects for energy and climate purposes. Through quantitative analysis and data visualization, the research centers on renewable-powered hydrogen projects, encompassing various production methods. Across 80 countries, Germany, Australia, and the United States exhibit the most projects (182, 118, 114). Most of the projects are in developmental stages, with 35% undergoing feasibility studies, 23% in concept stages, and 15% operational. Notably, 66 operational projects are renewable-powered, Germany leading with 19, followed by China (8), Great Britain, and Spain (4 each). Technologies include proton exchange membrane electrolysis, alkaline electrolysis, and others. This work underscores global hydrogen production efforts, spotlighting countries pioneering renewable-driven facilities for this energy carrier.
