Japanese shipping major Mitsui O.S.K Lines (MOL) has announced its intention to invest in the UK-based startup Carnot for its innovative engine technology aimed at significantly enhancing fuel efficiency by up to 40%. Carnot, in collaboration with MOL (Europe Africa), is working on engine technology that minimizes energy loss during the cooling process by utilizing highly heat-resistant materials, leading to improved thermal and fuel efficiency. The engine being developed by Carnot has the potential to revolutionize fuel efficiency in comparison to traditional engines by offering a remarkable 20%-40% enhancement. MOL plans to evaluate the technology's feasibility and performance through demonstration tests, with a possibility of future implementation across its merchant vessel fleet. This strategic investment aligns with MOL's 'BLUE ACTION 2035' management plan, which focuses on sustainable growth to address social and environmental concerns. By investing in Carnot, MOL aims to reduce greenhouse gas emissions from its vessels, enhance economic efficiency, and contribute towards GHG reductions in the broader shipping industry and other sectors relying on internal combustion engines. Furthermore, Carnot's success extends to being selected for the Clean Maritime Demonstration Competition for the fourth consecutive year, demonstrating its commitment to decarbonization in the maritime sector. In a separate initiative, Carnot has partnered with Carisbrooke Shipping to develop a zero-emission hydrogen auxiliary engine demonstrator. This project involves designing a 50kW single-fuel hydrogen engine, which will be integrated into a containerized system and tested on one of Carisbrooke's cargo vessels during a 40-day sea trial in early 2025 to provide electrical power. The collaboration between Carnot and Carisbrooke Shipping highlights the ongoing efforts towards sustainable and innovative solutions in the maritime industry.
