Brazil is taking steps to regulate its green hydrogen market, with a focus on overcoming challenges to attract investments. Leandro Alencar of ABHIC emphasizes the need for significant investments in hydrogen infrastructure to support production, distribution, and storage networks. Cost reduction is crucial, aiming to lower green hydrogen production costs to compete with gray hydrogen. Regulatory uncertainties and the need for harmonization with international standards pose additional hurdles. Clean Energy Latin America's studies show Brazil's potential to produce green hydrogen and ammonia competitively. Recent contracts, like the one between Prumo Logística and Fuella AS, indicate progress in establishing green hydrogen and derivatives hubs. To address uncertainties, regulatory sandboxes and specific solutions are proposed. Brazil's efforts to optimize green hydrogen production costs, enhance regulatory frameworks, and attract foreign investments demonstrate a positive outlook for the country's hydrogen market.
