Abstract:	The study explores the role of green hydrogen as a promising substitute for fuels in transportation, with an emphasis on its sustainable perspective. Green hydrogen is produced through water electrolysis, using renewable energy, which makes it an environmentally friendly option. Additionally, its use in vehicles presents significant advantages, such as zero pollutant emissions and higher energy efficiency. However, there are technical and economic challenges to overcome, such as expanding the refueling infrastructure and reducing production and storage costs. Nevertheless, the growing interest and investment in green hydrogen-related technologies demonstrate its potential as a sustainable solution for decarbonizing transportation. The work highlights green hydrogen as an energy source with high energy efficiency, low emissions, and water production as a byproduct, setting it apart from other sources. While bioenergy has variable efficiency and relies on agricultural land, and electricity is highly efficient but requires expanding recharge infrastructure, green hydrogen emerges as an option that combines high energy efficiency with low emissions, offering a potentially more comprehensive and sustainable solution for the transportation sector. In addition to discussing the role of green hydrogen as a fuel substitute in transportation, the study highlights Brazil's potential in this area. The country has great potential for generating renewable energy (solar, wind, and biomass) due to its vast availability of natural resources and expertise in the field. This abundance of resources would allow the country to produce green hydrogen sustainably, using electricity generated by these clean sources in water electrolysis, and enable exportation of production. Another important point is Brazil's vast fleet of fossil fuel-powered vehicles; however, transitioning the fleet to use green hydrogen involves multiple challenges and considerations. Considering an average efficiency of 70%, it would be necessary to generate approximately 60-70 kWh of electricity to produce 1 kg of hydrogen, benefiting from the national energy matrix with renewable sources. With an average consumption of 1 kg of hydrogen every 100-120 km, the Brazilian fleet of 50 million vehicles running an average of 15,000 km per year per vehicle, the annual demand would be approximately 4.167 million tons of hydrogen. Such demand would require a significant expansion of renewable electricity generation capacity, estimated at approximately 2,083 additional TWh per year. In summary, Brazil has enormous potential to become a major player in the production and use of green hydrogen in transportation. Transitioning to the use of green hydrogen in transportation can significantly contribute to reducing greenhouse gas emissions, helping the country meet its carbon reduction targets and driving the country's green economy. With a proper strategy involving public policies, sector cooperation, and government support, it is possible to leverage the use of green hydrogen in transportation, driving the transition to a cleaner and more sustainable future.
