This study elucidates how advances in biohydrogen production technology facilitate the development of biohydrogen and increase global competition. A dynamic economic model, the "Global Trade Analysis Project (Dynamic GTAP)", forecasts the competition and roadmaps of biohydrogen development in Asia, Europe, Latin America, North America and Oceania. Biohydrogen appears to be a viable technology to generate hydrogen in Latin America and Oceania. The two continents will be the fastest ones to achieve the technology roadmap target before 2060. Development of biohydrogen in Europe and North America will slow down. Asia lags behind last in global competition in this sector. Results of this study provide a valuable reference for decision makers using possible biohydrogen roadmaps in continental levels to improve the likelihood of successfully transiting to a biohydrogen economy in national level.
