Petredec & Carnot Drive Sustainable Marine Engine Future | Mariner News

Petredec, a leading LPG firm, has joined forces with UK startup Carnot Engines to pioneer the next generation of alternative marine engines. This strategic collaboration aims to revolutionize shipping and other transport sectors by developing highly efficient power units capable of operating on a diverse range of low-carbon fuels, significantly advancing the maritime industry’s decarbonization efforts.

Advancing High-Efficiency Engine Technology

At the heart of this innovation is Carnot’s opposed-piston engine design, which targets an impressive thermal efficiency of up to 70%. This breakthrough promises substantial reductions in fuel consumption and greenhouse gas emissions compared to conventional engines. Designed for multi-fuel capability, these advanced marine engines can seamlessly switch between LPG, LNG, ammonia, hydrogen, methanol, and traditional diesel, offering unparalleled operational flexibility for vessel operators pursuing sustainable maritime solutions.

Accelerating Sustainable Shipping Solutions

Petredec’s investment extends beyond financial backing; they will specifically support the development of an LPG-fuelled version, leveraging their extensive operational and shipping expertise. This powerful synergy between Petredec’s industry knowledge and Carnot’s innovative engine technology is set to accelerate the deployment of these sustainable marine engines across transport, maritime, and power generation markets. Durability testing is slated for Q2 2026, with initial commercial demonstrators expected later that year, marking a significant step towards a greener future for global shipping.
