Global marine fuel testing firm VPS has indicated that the commercial argument for using B100 biofuel is gaining ground, as ongoing conflict in the Middle East continues to squeeze distillate supply and drive up conventional fuel costs, according to a report published by Ship & Bunker.
A Shifting Price Equation
According to Ship & Bunker, Paul Hoather, Sales Manager at VPS UK, outlined in a report how supply disruptions tied to reduced flows through the Strait of Hormuz have significantly tightened the availability of marine distillates. When combined with elevated war risk insurance premiums, the knock-on effect has been a notable rise in distillate prices. VPS estimates that approximately 1.15 million barrels per day of middle distillates are affected by these constraints.
The result, as Ship & Bunker reports, is a narrowing of the price differential between conventional marine fuels and FAME-based B100. While B100 carries a higher nominal cost per tonne, its competitive position on a voyage-cost basis has improved considerably under current market conditions. Hoather also noted that B100’s emissions profile supports compliance with FuelEU Maritime regulations, offering operators an additional avenue for reducing carbon-related compliance costs.
Ship & Bunker reports that B100 uptake is on the rise, though blended options such as B30 continue to be more widely adopted, largely due to the lower operational risk associated with partial blending.
Operational Readiness Remains Essential
Despite the strengthening commercial case, VPS emphasised that switching to B100 is not without its challenges. As reported by Ship & Bunker, the firm highlighted risks specific to FAME-based fuels — including oxidation, water absorption, and microbial growth — which make comprehensive fuel testing a critical step before use. VPS’s APS-FAME testing service is designed to go beyond the standard ISO 8217:2024 analysis, assessing fuel stability, contamination levels, and overall fitness for use.
On the operational side, VPS recommends that vessels complete thorough tank cleaning and flushing before introducing B100, in order to minimise residual water content and reduce microbial risk. The firm also advises carrying out compatibility checks across all fuel system components.
Ship & Bunker further notes that VPS cautioned against onboard blending where it can be avoided, pointing out that FAME’s higher solvency properties can dislodge tank residues and place added strain on purification systems, particularly during the initial transition period. In cases where blending is unavoidable, VPS recommends a gradual approach, supported by continuous monitoring of both fuel quality and engine performance.
