Cummins Methanol-Ready Engine gets DNV Approval

Cummins recently obtained Approval in Principle (AIP) from DNV for its methanol-ready QSK60 IMO II and IMO III engines, which offer power ratings ranging from 2000 to 2700 hp. This approval signifies the validation of Cummins’ methanol dual-fuel solution for the global marine market. The company plans to introduce retrofit kits for these engines after 2028 to coincide with market demand and infrastructure readiness. These kits, designed for diesel-electric systems, can also be paired with battery technology to enhance efficiency and sustainability.

According to Dawn Wehr, Cummins’ Executive Director of Strategy, Product Planning & Digital, implementing a retrofittable solution eliminates the need for a major vessel overhaul and immediately contributes to reducing carbon emissions. Cummins is also exploring solutions for other alcohol fuels like ethanol to cater to various operations and fuel infrastructure availabilities, facilitating easier adoption by the industry. This approval builds upon Cummins’ previous announcement in August 2023, allowing the use of renewable diesel, such as hydrotreated vegetable oil (HVO), in its high-horsepower engine range. By incorporating renewable diesel in dual-fuel solutions, ship operators can make substantial strides in cutting down carbon emissions.

The approval from DNV underscores Cummins’ commitment to sustainability and innovation in the marine industry. By continuously developing solutions for alternative fuels and retrofitting options, Cummins aims to provide flexible and environmentally friendly choices for vessel operators. Leveraging renewable diesel and exploring other alcohol fuels demonstrate Cummins’ dedication to reducing the environmental impact of marine transportation.
