Oak Ridge National Laboratory, in collaboration with Caterpillar Inc., has developed a dual fuel combustion system that addresses methanol ignition challenges in diesel engines for marine vessels. By combining methanol with a small amount of diesel, the system allows engines to operate efficiently on over 75% methanol, enhancing sustainability without extensive redesign.
Everllence has achieved a groundbreaking milestone by converting the world’s first B&W S90 two-stroke engine to dual-fuel methanol. Following successful sea trials on COSCO Shipping Libra, this project highlights the feasibility of large-scale retrofits, with over 300 S90-class engines worldwide, paving the way for sustainable maritime energy solutions.
A recent project by the Maersk Mc-Kinney Møller Center focused on converting Kamsarmax bulk carriers to dual-fuel methanol operations. The project aimed to assess the feasibility of retrofitting fuel oil-powered vessels to run on methanol, with Approval in Principle from Japan’s ClassNK. It highlights the potential for low-emission solutions in the maritime industry.
Shipowners are seeking ways to extend vessel life while meeting IMO decarbonization goals. Lomar Shipping’s lomarlabs is collaborating with Newlight to create hydrogen retrofits for ships, allowing diesel engines to use a hydrogen blend. This innovative approach could cut fuel use by up to 30%, with pilot installations set for summer 2025.
