Brazil is taking significant steps towards the Energy Transition, aiming to shift from polluting energy sources to renewables. The focus is on renewable energy, decarbonization, digitalization of energy distribution, and regulatory initiatives. Green Hydrogen (H2V) is seen as the future energy source due to its zero greenhouse gas emissions. However, challenges exist in the tax landscape, as all hydrogen types are generically classified. The lack of specific tax benefits for clean hydrogen production hinders its growth. Legislative efforts, like Law 14.948/20241 and Provisional Measure 1.205/23, are promoting the Green Hydrogen Market. Brazil also aims to encourage the Energy Transition through tax reforms, with a priority on environmental protection. Recent bills target energy potential in offshore areas, carbon market regulations, and the promotion of future fuels. The country is moving towards a favored tax regime for biofuels and low-carbon hydrogen, supporting a cleaner energy future.
