Singapore: GCMD introduces new technique for FAME bio bunker fuel fingerprinting

The Global Centre for Maritime Decarbonisation (GCMD) on Monday (2 December) released its latest report, presenting a new technique that creates a fingerprint for Fatty Acid Methyl Esters(FAME) bio bunker fuels.

This fingerprint identifies the feedstock origins of the FAME-based biofuels used in the shipping industry.

GCMD said FAME fingerprinting is needed as the shipping sector is increasingly using biofuels, such as FAME, to reduce its GHG emissions. With that, concerns have arisen regarding the legitimacy of biofuels and whether they are truly sustainable. 

Industry bodies are seeing a rising number of cases mislabelling biofuels purported to be made from recycled oils and fats, while suspicions persist that they might be produced from cheaper and less sustainable virgin oils.

“To address these concerns, FAME fingerprinting can be used as a potential tool to detect fraud in marine fuel supply chains and ensure biofuel authenticity. By providing a physical validation method that complements existing certification schemes, FAME fingerprinting can help justify the green premium with genuine environmental benefits and safeguard the integrity of marine fuels supply chain,” GCMD said. 

FAME fingerprinting is based on the principle that the fatty acid profile of FAME is unique to its feedstock and can be preserved during feedstock transesterification to produce FAME. The “fingerprint” can then be compared against a database of known fatty acid profiles to identify the feedstock origin. 

GCMD worked with VPS who modified existing fuel testing methods to carry out sample analyses using a gas chromatograph with flame-ionisation detection, an instrument commonly found in fuel test laboratories. 

The analysis takes about an hour, comparable to the turnaround time for current marine fuel quality testing in the supply chain. 

“We have tested this method on a variety of FAME samples from different suppliers, including virgin oils, used cooking oils, palm oil mill effluent, beef tallow and food waste and were able to identify the feedstock origins for each sample,” GCMD added.

Manifold Times previously reported Captain Rahul Choudhuri, President, Strategic Partnerships at marine fuels testing company VPS, forecasting the use of finger printing technology today will likely establish a blueprint of how future alternative bunker fuels’ feedstocks are authenticated.

Captain Choudhuri said this when he gave an update of VPS’ biofuels finger printing trials with GCMD.
