Special Issue Information

Dear Colleagues,

The Intergovernmental Panel on Climate Change Special Report (IPCC, 2018) was addressed to governments in relation to reducing the greenhouse gas (GHG) emissions and limiting global warming to 1.5 °C above pre-industrial levels. The report stressed the need for a global shift from conventional to renewable energy due to increasing energy demand, fossil fuel scarcity, high costs, and environmental concerns. Such a transition can lay the groundwork for decarbonization targets and achieve net-zero CO2 emissions by 2050. This report addressed the production and utilization of hydrogen gas, because this is the only fuel without GHG emissions. In particular, if it is produced from renewable energy sources, including hydroelectric, wind, solar, biomass, and biogas, it is the cleanest fuel and is called green hydrogen (GH2). Therefore, it is important to publicize research and reports on the subject, to contribute to the technological development of green hydrogen production.

We are pleased to invite you to submit your scientific contribution to the Special Issue, entitled “Recent Advances in Green Hydrogen Production Processes”, in the journal Processes. In this Special Issue, original research articles and reviews are welcome. Articles on GH2 production are welcome, as well as any report containing information on GH2 production such as photofermentation, biomass fermentation, and water electrolysis, which are powered by hydroelectric, photovoltaic, wind, or geothermal energies.

We look forward to receiving your contributions.

Prof. Dr. José Carlos Curvelo Santana

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.
