en.Wedoany.com Reported - NYK has initiated a one-year trial on an operating car carrier using 100% biofuel (B100), marking a practical test in the company's shipping decarbonization efforts.

The program aims to evaluate the long-term safety, stability, and mechanical performance of high-purity biofuel under real-world operating conditions. The fuel used in the trial is fatty acid methyl ester (FAME), primarily derived from sustainable feedstocks such as waste cooking oil. As a "drop-in" fuel, B100 is compatible with existing marine engines and infrastructure, enabling greenhouse gas emission reductions without requiring major modifications to vessels.

Unlike lower-blend fuels such as B24 and B30, which NYK has successfully tested previously, B100 presents additional challenges. High-purity biofuel is more susceptible to degradation from oxygen, heat, and light, raising concerns about its long-term storage and operational reliability. Throughout the one-year trial, the company will continuously monitor the biofuel's impact on engines, fuel supply systems, and daily vessel operations.

Given the limited global experience with continuous use of pure biofuel in deep-sea shipping, NYK aims to collect comprehensive data through this trial to support the safe large-scale application of B100 and contribute to broader industry knowledge. The company views this trial as a key step in expanding alternative fuel use and accelerating the transition to sustainable maritime transport, with findings expected to inform future technical assessments and support its fleet's broader decarbonization plans.
