Brazil is working on regulating its green hydrogen market, but challenges remain in developing the necessary infrastructure and reducing production costs. Leandro Alencar from ABHIC highlights the need for significant investments to build a robust network and decrease production costs to compete with gray hydrogen. Regulatory uncertainties and the importance of harmonizing national and international standards are also key concerns. Clean Energy Latin America's studies show Brazil's capability to produce green hydrogen and green ammonia cost-effectively, benefiting from optimizations and incentives. The recent contract signed by Prumo Logística, Porto do Açu Operações, and Fuella AS in Rio de Janeiro state signifies a step towards establishing a low-carbon hydrogen hub, focusing on green ammonia production for export and domestic use. The partnerships aim to drive technological innovation and decarbonization in Brazil's energy sector, aligning with global trends towards sustainable fuels.
