GCMD, VPS develop new sustainability test for FAME biofuels

Singapore-based Global Centre for Maritime Decarbonisation (GCMD) and marine fuel testing firm VPS have collaborated on the initiative. The test can identify the source of the bio-component used in FAME-based biofuels.

VPS uses a forensic analytical technique, gas chromatography, to determine the source of the bio component. Gas chromatography is a method used to study the elements of a mixture, especially liquids that can turn into vapour.

GCMD and VPS say VLSFO has a distinct chemical fingerprint compared to FAME.

"Given the distinction between VLSFO and FAME, this method can be applied to identify the presence of FAME and the amount present in blends with residual fuel oils," GCMD's report said.

The test method can be used for all FAME-based biofuels up to B100. VPS adds that testing is important as not all FAME-based biofuels have the same properties and most suppliers do not indicate the source oil of the bio component.

“This [testing] is becoming increasingly important as the availability of FAME is driving suppliers to source FAME-based biofuels from an increasingly wide variety of exotic source oils,” VPS noted. 

The analysis is “a potential tool to detect fraud in marine fuel supply chains and ensure biofuel authenticity”, the GCMD states.  

With the FuelEU maritime set to come into force in 2025, there has been an increased interest in biofuels. Industry bodies have, however, often expressed concerns over biofuel sustainability.
