Pathways for Hydrogen Adoption in the Brazilian Trucking Industry: A Low-Carbon Alternative to Fossil Fuels

The growing demand for sustainable solutions in the transportation sector and global decarbonization goals have fueled debate on using hydrogen as an energy source. Although hydrogen’s potential is recognized in Brazil, its application in heavy-duty vehicles still faces structural and technological barriers. This study aimed to analyze the viability of hydrogen as an energy alternative for trucks in Brazil. The research adopted an exploratory qualitative approach, based on the expert analysis method, through semi-structured interviews with development engineers, representatives of heavy-duty vehicle manufacturers, and researchers specializing in hydrogen technologies. The data were organized into a thematic framework and interpreted using content analysis. The results show that, although there is growing interest and ongoing initiatives, challenges such as the cost of fuel cells, the lack of refueling infrastructure, and low technological maturity hinder large-scale adoption. From a theoretical perspective, the study contributes by integrating specialized literature with practical insights from key industry players, broadening the understanding of the energy transition. In practical terms, it outlines some strategic paths, such as expanding technological development and forming partnerships. From a social perspective, it emphasizes the importance of hydrogen as a pillar for sustainable, low-carbon mobility, capable of positively impacting public health and mitigating climate change.
