Petredec has partnered with Carnot Engines to develop engines designed for multiple alternative fuels, including LPG, LNG, ammonia, hydrogen, methanol, and diesel, targeting thermal efficiency of up to 70%. This collaboration will leverage Petredec's shipping expertise and Carnot's technology to enhance deployment across shipping, transport, and power generation sectors.

Petredec will support the development of an LPG-fueled version and acquire shares in Carnot. Durability testing is expected to commence in Q2 2026, with initial commercial demonstrators projected for H2 2026. LPG is currently a niche alternative bunker fuel, primarily used in gas carriers.
