Abstract
This paper aims to present the theoretical potential of green hydrogen production from biomass in Minas Gerais, Brazil. The main limitations to achieve the theoretical potential of green hydrogen production from biomass are discussed. The technological pathway for green hydrogen production considers electricity generation from biomass and proton exchange membrane electrolyzers. The biomass considered in potential for green hydrogen production were coffee, sugar cane (and vinasse), corn, soy, wood, and animal liquid manure. The amount of biomass was based on IBGE 2020-year production data. The methodology for the calculation of the electricity generation potential from the different biomass considered was exposed in the “Biomass Atlas of Minas Gerais”. This methodology for the above analysis uses the annual production, the thermal efficiency of the electricity generation system, the lower heating value, density, and other biomass parameters. Later the green hydrogen production was estimated using the hydrogen generation index of the Silyzer 300 electrolyzer. The results of the calculations show a theoretical potential of hydrogen production from coffee, sugar cane (and vinasse), corn, soy, wood, and animal liquid manure of 9.374.920,01 kgH2/year, 90.029.226,60 (and 27.742.056,63) kgH2/year, 80.089.123,44 kgH2/year, 28.538.453,67 kgH2/year, 68.746.448,70 kgH2/year, 104.001.143,04 kgH2/year, respectively. From these results it can be concluded that the theoretical potential of green hydrogen production in Minas Gerais is considerable (more than 406 million kgH2/year) and that despite the limitations until reaching real production the state of Minas Gerais can become a relevant producer of green hydrogen in the national economy.
