A recent study conducted by the National Technical University of Athens has confirmed that marine fuel consumption and associated emissions can be reduced more quickly and cost-effectively than previously assumed. The research, which utilized a fuel treatment technology developed by UK-based Fuelre4m, demonstrated measurable efficiency improvements in large marine engines operating on conventional marine fuels.
7%, while real-world operation showed propulsion efficiency improvements of up to 21%. The results were achieved without engine modifications or alterations to fuel specifications, and were attributed solely to changes in fuel behavior during combustion.
This study provides valuable insights for shipowners and operators assessing compliance pathways under tightening international and regional emissions frameworks, including IMO decarbonization targets. Rather than relying solely on newbuilds, alternative fuels, or long-term infrastructure investments, the study points to a near-term option applicable to vessels currently in service.
The research results are significant as they demonstrate that existing engines and fuels can be optimized to deliver efficiency gains, providing immediate economic and environmental benefits. This approach can help reduce costs associated with fuel consumption and minimize emissions, ultimately contributing to a more sustainable maritime industry.
The study's findings also underscore the importance of exploring alternative solutions to achieve decarbonization targets, particularly for vessels currently in operation. By leveraging existing technologies and fuels, shipowners and operators can take proactive steps towards reducing their environmental footprint while minimizing costs associated with fuel consumption.
This study highlights the potential for existing technologies to deliver significant efficiency gains in marine engines, which can help reduce emissions and costs associated with fuel consumption. By exploring alternative solutions that build on existing fuels and engines, shipowners and operators can take proactive steps towards achieving decarbonization targets.
