Over the years, greenhouse gas emissions have grown significantly. In 2015, the countries participating in COP21 signed the Paris Agreement, agreeing to limit global warming to below 2 degrees C. The search for carbon neutrality in the Brazilian energy sector by 2050 will involve replacing current sources with low-carbon alternatives, such as hydrogen, and processes with carbon sequestration and storage (CCS). Hydrogen, however, can only be an alternative if, during its production process, no CO2 emissions occur, which is not currently a reality, given that the most mature technological route for H2 production is the steam reforming of fossil fuels, which result in gray hydrogen. To reduce the CO2 intensity, alternative production methods are being considered. Among them, green hydrogen, produced from the electrolysis of water using renewable electricity, and blue hydrogen, which has a process equivalent to gray hydrogen, but with a subsequent CCS step. The objective of this work was to better explore the technological route for the production of blue hydrogen applied to the Brazilian context, performing a technical analysis, which consisted of mapping regions with potential for implementing the technological routes studied, in addition to economic analysis, with price comparison of gray and blue hydrogens in Brazilian territory today, and environmental, analyzing the possible impacts of emission reductions when adding CCS to the production of H2 by the refining sector. Finally, it was concluded that the Southeast is the most likely region to host the production of blue hydrogen, but that there are other options, such as the Northeast, that could be used for pilot projects. As for the economic aspects, the implementation of CCS can represent significant cost increases, which can reach 1100 percent when compared to the gray hydrogen production route, which is more technologically mature. Regarding environmental impacts, the use of CCS units can reduce by up to 90 percent the emissions related to the production of H2 in the refining sector and reduce the global warming potential of the activity by up to 70 percent.
