Abstract
This study considers the production of hydrogen in Brazil through water electrolysis using renewable energy sources, namely solar, wind, and hydropower. The study aims to establish a correlation between the country’s green hydrogen production capacity and the fossil fuel consumption aiming the transportation sector. The findings reveal that a transition to hydrogen-powered vehicles in Brazil would require approximately 6.3 billion kilograms of hydrogen per year, which is six times the current national production. Meeting this demand would require a significant increase in renewable energy production, with approximately 60 % of Brazil’s renewable energy grid (excluding biomass) required for hydrogen production. However, directing such a substantial portion of the renewable energy grid exclusively towards hydrogen production presents challenges and may not be economically viable. Nonetheless, the study proposes a favorable future scenario by gradually expanding the fleet and renewable hydrogen production in line with Brazil’s renewable energy growth, which would require a 1.4% increase in photovoltaic, wind power, and hydropower combined capacity over 10 years to accommodate the additional hydrogen-powered vehicles.
