BAKU, Azerbaijan, Jan.6. Driven by the decarbonization push, the fuel mix in the maritime subsector will change significantly over the coming decades, reads a report published by DNV GL, Trend reports Jan.6.

“It will transition from being almost entirely oil-based today to a mix dominated in 2050 by the use of low- and/or zero-carbon fuels (50 percent), natural gas (19 percent, mostly liquefied natural gas) and biomass (18 percent). Ammonia will have the highest share (35 percent) of low-and zero-carbon fuels and e-fuels 15 percent. Electricity will have only 2 percent,” reads the report.

DNV notes that this massive fuel switch will be supported by many regionally imposed decarbonization efforts.

“Maritime transport is by far the most energy efficient transportation in terms of energy per tonne-kilometre. Consequently, over 80 percent of the volume of internationally traded goods is carried by sea (UNCTAD, 2021). Nearly 3 percent of global final energy demand, including 7 percent of the world’s oil, is presently consumed by ships, mainly by international cargo shipping. The IMO regulation capping the sulfur content of ship fuel came into force in 2020, dramatically changing the type of fuels being used. The main shift has been to a much larger share of lighter distillates in the overall fuel mix, or other variants of fuels with less sulfur. However, a significant share of marine heavy fuel oil is still being used on ships with scrubbers installed,” the report says.
