The maritime industry moves over 90% of global trade, but it’s under mounting pressure. Fuel and carbon already make up more than half of voyage operating costs, and with new levies and regulations coming into force, that burden will only increase. Incremental fixes won’t protect margins. Operators need a solution that works today and future-proofs their fleets.

So far, no incumbent has delivered a step change in combustion efficiency. Most innovation has focused on what fuel goes into the engine, not on how that energy is converted into useful work.

That’s why we’re building the CV50 engine: a propulsion breakthrough designed to deliver a step-change in efficiency. CV50 cuts fuel use and emissions by up to half while integrating seamlessly with existing vessels and infrastructure. 

The CV50 architecture advances beyond the conventional diesel cycle by moving heat release closer to true constant-volume conditions and reducing heat-transfer losses. It targets up to 70% brake thermal efficiency, delivering substantial specific fuel consumption (SFC) and CO₂ reductions at equivalent power output. Its fuel flexibility, from fossil diesel to bio- and e-fuels, provides a scalable route to immediate, verifiable tank-to-wake emission cuts, compounding further as cleaner fuels mature.
