ICCT report identifies six Brazilian ports as potential renewable marine fuel bunkering hubs

A new report by the International Council on Clean Transportation (ICCT) on Thursday (5 June) has identified six Brazilian ports as candidate hubs for renewable marine fuel bunkering. 

The report analysed the readiness of Brazilian ports to support the production, bunkering, and deployment of renewable hydrogen and its derivatives, such as renewable ammonia and renewable methanol, laying the groundwork for establishing green shipping corridors.

Three are public ports—Santos, Rio Grande, and Itaqui—and three are privately owned ports—Pecem, Navegantes, and Porto do Açu. Santos, the largest port in Latin America, ranked high in four out of the five criteria assessed for readiness, though it had only a moderate level of commitment to decarbonisation due to a lack of ongoing or planned offshore wind projects. 

Porto do Açu and Itaqui scored high on all criteria except for access to potential offshore wind energy. Public ports generally scored higher than private ports, especially for their infrastructure, strategic location, and connectivity. On a scale of 1 to 5, the six candidates chosen for further assessment had weighted scores that ranged from 3.5 to 4.4.

Based on 2023 ship traffic, the report also identified 10 routes connecting the six candidates to both the domestic market and key international markets. Among the 10 sample routes moving key commodities, including iron ore and container cargo, between the candidate ports and ports around the world, the report estimated that five routes could be completed with direct use of renewable liquid hydrogen in a fuel cell without refuelling en route. The report found all routes could be completed without refuelling if ships use renewable hydrogen-derived ammonia and methanol in internal combustion engines. 

To successfully complete all 10 routes, with at least one ship on each route, a total energy of 1,785 tonnes of hydrogen is required if the minimum consumption of renewable fuel is considered across all routes. 

“Conversely, if we look at the maximum consumption of renewable fuel for all 10 routes, the total energy requirement is 1,911 tonnes. This translates to a demand for renewable electricity of 82 to 92 GWh,” the report said.

ICCT said the pre-feasibility assessment demonstrates the significant potential of Brazilian ports to serve as renewable marine fuel hubs, offering both economic and environmental benefits. 

“By quantifying the potential bunkering demand and analysing port readiness, this study provides a guideline for future investments and policy initiatives aimed at accelerating the decarbonisation of maritime shipping,” it added.
