The International Council on Clean Transportation (ICCT) released a report focusing on the potential of Brazilian ports to become renewable marine fuel bunkering hubs, leveraging the country's renewable energy resources and strategic location. The study assessed the readiness of six candidate ports, including both public and private ports like Santos and Porto do Açu, to support the production and deployment of renewable hydrogen and its derivatives for green shipping corridors. Key findings included high port readiness scores, with Santos ranking well across multiple criteria and the feasibility of using renewable hydrogen derivatives on major shipping routes without mid-route refueling. The estimated demand for renewable hydrogen to enable zero-emission shipping routes was highlighted, showcasing the sustainable energy transition required in the maritime industry. The study emphasized the importance of factors like existing renewable energy use, port capacity, infrastructure, location, and commitment to decarbonization in evaluating port readiness for bunkering renewable marine fuels. Despite the positive outlook, realizing the full potential of renewable fuel alternatives will necessitate significant investments and collaboration among stakeholders. ICCT plans to delve deeper into the scaled demand for renewable marine fuel in Brazil in future studies, aiming to explore the economic and environmental benefits of transitioning to green shipping practices.
