Purpose Hydrogen has enormous decarbonization potential in the transportation sector. Heavy vehicles, maritime transport, aviation and railways are exploring hydrogen as a solution. is important future mobility solution because global regulations for emissions reduction becoming increasingly stringent. The European Green Deal aims to reduce greenhouse gas (GHG) by 90% 2050 compared 1990 levels, affecting industry. will play crucial role achieving climate goals, especially public transport mobility. A rigorous statistical study of production capacities becomes essential context that holds transportation. analyzes evolution annual capacity from 2009 2022. Until 2015, main technology used was alkaline water electrolysis, while 2016, polymer electrolyte membrane (PEM) electrolyzer became dominant. Alkaline electrolysis 22% higher PEM technology. It been observed Asia largest operational at 43.3%, followed Europe 26.8%, USA 26.2%, Africa 3.5% Australia 0.3%. countries with highest China 41.7%, 25.7% Germany 7.4%. Design/methodology/approach involved analysis data related systems use mobility, conducted over an extended period 2011 represents detailed look this vital sustainable seen significant development recent years, driven increasing awareness adverse impact GHG on environment need cleaner more efficient solutions In study, we analyzed each country, also tracking its time. Additionally, investigated continental-level capacity, providing comprehensive overview progress production. Findings promising decarbonizing Its using renewable energy sources such solar wind power can significantly carbon emissions. be fuel cell vehicles zero-emission cars transportation, contributing fight against change creation our highlighted highly dynamic. During approximately 1,570 cubic meters per hour (m 3 H2/h). However, what evident impressive growth area. Between 2016 2020, increased significantly, reaching 6,240 m H2/h, which roughly fourfold increase previous period. Originality/value factor spurred commitment reducing other pollutants recognized viable alternative due their generate environmentally friendly hydrogen, commonly referred green through utilization or power. Over researchers have made advancements field generation, specifically areas natural reforming. These approaches played improving efficiency both gray considered one most associated minimal even nonexistent.
