Analysis of the Sugarcane Biomass Use to Produce Green Hydrogen: Brazilian Case Study

Short Introductive summary

Conventional hydrogen production processes, which often involve the use of fossil raw material, are among the main emitters of carbon dioxide in the atmosphere. Biomass can be transformed into fuels and chemicals of high added value through thermochemical and biochemical conversion techniques. In the core of sugarcane production, Brazil occupies the first position in the world ranking, being considered the greatest power in the manufacture of this compound. Hydrogen, an abundant element whose complete combustion is clean, is pointed out as a global bet towards a future renewable energy matrix. Therefore, the objective of this study is to evaluate in a critical and analytical way the feasibility of using sugarcane biomass as a green hydrogen vector. Finally, the current Brazilian scenario of sugarcane production is evaluated through the qualitative analysis of the 2022/2023 crop produced by the National Supply Company (Conab). It was verified the existence of seven different methods to obtain biohydrogen, two from the direct use of 2G ethanol and five from simultaneous production.
