Independently tested technology can deliver fuel efficiency and emissions gains for existing fleets

Independent University tests has proved that marine fuel consumption and associated emissions could be reduced more quickly and cost-effectively than previously assumed, using existing vessels and standard fuels already in circulation.

A study conducted by the National Technical University of Athens (NTUA) has found that a fuel treatment technology developed by Fuelre4m delivered measurable efficiency improvements in large marine engines operating on conventional marine fuels.

In the most conservative fixed test condition, where shaft speed and load are deliberately held constant, fuel consumption was reduced by 3.5–6.7%, demonstrating that the fuel delivers more usable energy per unit consumed. In real-world operation, where engines are not artificially constrained and can reduce load to achieve the same work, this improvement expresses as a materially larger efficiency gain, with independent testing showing propulsion efficiency improvements of 21% and above.

The results were achieved without engine modifications, hardware changes, or alterations to fuel specifications. According to the researchers, the efficiency gains were attributable solely to changes in fuel behaviour during combustion.

The findings have huge implications across the maritime sector, which consumes more than 200 million tonnes of fuel annually and continues to face rising pressure to reduce emissions while managing operating costs. Even incremental efficiency gains, if adopted at scale, could contribute to meaningful reductions in greenhouse gas emissions and fuel expenditure across global fleets.

The research comes as shipowners and operators assess compliance pathways under tightening international and regional emissions frameworks, including IMO decarbonisation 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.

George Papalambrou, Associate Professor at the National Technical University of Athens, said:

“We were surprised by how consistent the efficiency improvements were across different operating conditions.”

Rob Mortimer, CEO of Fuelre4m, commented:

“Fuel remains one of the most significant cost components in maritime operations. Reducing consumption delivers immediate economic and environmental benefits. What’s notable here is that these results were achieved using existing engines and fuels, allowing operators to act now rather than waiting for future solutions.”

About Fuelre4m

Fuelre4m’s (Fuel Reform) product range, Re4mx (Reform Mix) is a powerful, completely organic, fossil fuel reforming nano-biotechnology that enhances the combustion process in engines. By breaking down impurities and complex hydrocarbons in liquid fossil fuels, the technology ensures a more efficient and cleaner burn, resulting in increased power output, lower fuel consumption, and a significant reduction in harmful emissions.

• Increased Efficiency: Users can expect over 21% reduction in fuel consumption as Fuelre4m’s Re4mx increases the power released and the combustion efficiency of any liquid fossil fuel.
• Cost Savings: With lower fuel consumption, Fuelre4m ensures that companies can achieve substantial cost savings on their fuel expenses, potentially generating increased budgets for other sustainability initiatives.
• Environmental Impact: A massive 40% to 80% reduction in NO, NO2, NOx, CO, SO, SO2, and particulates translates into a cleaner and healthier environment, aligning with global efforts to combat air pollution.

Fuelre4m is strategically positioned to serve industries that heavily rely on fossil fuels, including Ports, Maritime and Shipping, Power Generation, Rail, and Public Transport. The company understands the unique challenges faced by these sectors and offers a solution that not only meets their energy needs but also aligns with their Environmental, Social, and Governance (ESG) and Corporate Social Responsibility (CSR) initiatives.

Fuelre4m invites businesses in Ports, Maritime and Shipping, Power Generation, Rail, and Public Transport to join the revolution toward cleaner and more efficient energy consumption. By adopting Fuelre4m’s technology, companies can demonstrate their commitment to combatting climate change and showcase tangible results to their customers.
