Description
This study presents a multicriteria methodology to compare possible alternative fuels for the Brazilian maritime trade. To this end, 14 fuel options are evaluated according to technical, economic, and environmental criteria to which different weights are assigned. The ranking of results indicates that drop-in fuels such as Fischer-Tropsch diesel, alcohol-based diesel, straight and hydrotreated vegetable oils and e-diesel stand out as promising mid-term alternatives. Biomass-based liquefied natural gas (Bio-LNG) performance in the evaluation is hampered mostly by the risk of methane slip. Green hydrogen and green ammonia, on the other hand, seem to be less competitive alternatives in the mid-term horizon for Brazil but may become alternatives for cabotage transport in the long-term.
