Global Centre for Maritime Decarbonisation concludes biofuels supply chain trials
The Global Centre for Maritime Decarbonisation (GCMD) has successfully completed its final supply chain trial for biofuel blended with very low sulphur fuel oil (VLSFO). This marks the end of a series of trials initiated in July 2022 as part of a larger pilot to develop a framework to provide quality, quantity and GHG abatement assurances for drop-in fuels, according to GCMD's release.
In this final trial, bp provided the B30 biofuel blend to the TIHAMA, a 19,870 twenty-foot equivalent unit (TEU) container vessel operated by Hapag-Lloyd.
The biofuel component used is certified to the International Sustainability & Carbon Certification (ISCC) standard – a multistakeholder certification scheme for biobased materials. The biofuel component comprised neat Fatty Acid Methyl Ester (FAME) produced from food waste.
Authentix, a tracer solutions provider, supplied and dosed the FAME with an organic-based tracer at the storage terminal outside the Netherlands. The dosed FAME was then transported to the Port of Rotterdam for blending with VLSFO to achieve a B30 blend, before the blend was bunkered onboard the TIHAMA.
Similar to previous trials, GCMD engaged fuel testing company Veritas Petroleum Services (VPS) to witness the operations at all stages – from biofuel cargo transfer to bunkering. VPS also collected and conducted extensive laboratory tests on samples of the biofuel and biofuel blend collected at pre-determined points along the supply chain to assess quality per Standards EN 14214 and ISO 8217.
With well-to-wake emissions of 13.74 gCO2e/MJ, the neat FAME presented a 85.4% emissions reduction compared to the emissions of the fossil marine fuel. The reduced emissions complies with the MEPC 80, which requires a minimum emissions reduction of 65% in order for biofuels to be classified as sustainable.
GCMD and Hapag-Lloyd determined that consumption of the 4,500 MT B30 blend of FAME and VLSFO resulted in 27.9% emissions reduction compared to sailing on VLSFO.
GCMD collaborated with Authentix to develop and deploy a new organic-based tracer to authenticate the origin and verify the amount of FAME present in the blend. The proprietary tracer blended homogeneously with FAME and was detected at expected concentrations at all sampling points along the supply chain.
This trial marks the first deployment of this tracer in a marine fuel supply chain. Previously, similar tracers were used to authenticate and quantify biofuels in road transport and LPG supply chains.
With the completion of this trial, GCMD has deployed a diverse range of tracer technologies, including synthetic DNA and element-based tracers, in addition to the organic-based tracer used in this trial. The trials have also included the development of a chemical fingerprinting methodology and the evaluation of lock-and-seal and automatic identification systems (AIS) as additional solutions to ensure the integrity of the biofuels supply chain.
Learnings on tracer limitations and benefits will be incorporated into a framework that recommends appropriate use to ensure consistent and robust performance. This effort will complement existing ISCC by providing additional supply chain assurance through physical traceability.
The insights from these trials will be shared in a series of reports covering issues, such as traceability, biofuel degradation, supply chain optimisation and abatement costs. These findings will culminate in a comprehensive assurance framework to provide guidance on biofuels use, slated for release in the fourth quarter of 2024.
