Tokyo, Japan — Nippon Yuka Kogyo Co., Ltd. (Nippon Yuka), a subsidiary of the NYK Group, has announced the release of BioxiGuard—Japan’s first antioxidant formulated specifically for marine biodiesel fuel. The product is scheduled to hit the market on August 10, marking a significant milestone in the maritime industry’s shift toward cleaner energy solutions.
“New additive cuts biofuel degradation by 50%, supporting cleaner and more efficient vessel operations.”
Tackling a Core Challenge of Marine Biofuels
Marine biofuels, particularly those derived from fatty acid methyl esters (FAME), are becoming an increasingly viable alternative to conventional fossil fuels due to their lower lifecycle carbon emissions and renewable feedstocks, such as waste cooking oils and agricultural byproducts. However, one of the longstanding technical hurdles for biofuel use at sea has been oxidative degradation—a process by which exposure to air and heat causes the fuel to deteriorate, leading to acid formation, sludge deposits, and decreased calorific value.
This degradation is primarily driven by the high content of unsaturated fatty acids in biodiesel, making it significantly more vulnerable than petroleum-based fuels.
Enter BioxiGuard: An Innovation from the Lab to the Sea
Developed through intensive in-house research and testing using biofuels onboard NYK-operated vessels, BioxiGuard was engineered to directly address the oxidation stability challenges of marine biodiesel.
According to experimental results shared by Nippon Yuka, the application of BioxiGuard at a concentration of 1 part per 500 led to a 50% reduction in the rate of oxidative degradation. This not only extends the onboard lifespan of stored biofuel but also helps prevent operational issues such as:
- Metal corrosion
- Strainer blockage
- Fuel cleaning system fouling
These benefits ultimately translate into higher fuel efficiency, lower maintenance costs, and increased reliability for ship operators using bio-based fuels.
