Fuelre4m aims to raise primary combustion efficiency from around 75% to as high as 93% – boosting power output and cutting emissions, all without engine modifications.
In this episode, I speak with Rob Mortimer, founder of the Dubai-based company Fuelre4m, about why fuel reform is one of the most overlooked levers for maritime efficiency.
Mortimer challenges long-held assumptions in the shipping industry, explaining the critical difference between rated engine power and actual delivered power — particularly when operating on lower-grade or alternative fuels such as biodiesel. Fuelre4m’s core solution, Re4mx, is a natural additive blend that restructures fossil fuels at the molecular level, improving combustion performance without altering the engine itself.
From shipping to upstream production and refining, Mortimer outlines how Fuelre4m’s tailored blends can lower energy input, enhance extraction, and even improve API gravity — making heavy fuels easier to handle and more valuable. He also unpacks common misconceptions in fuel performance measurement, pointing out why tools like torque meters, when used in isolation, can mislead operators.
Grounded in a background in telecoms and precision systems, Mortimer’s approach is data-led and verifiable — with ambitions to integrate AI, blockchain, and end-to-end fuel system tracking into one of the industry’s most established yet most legacy-heavy and data-fragmented systems.
