Global Centre for Maritime Decarbonisation concludes biofuels supply-chain trials

The Global Centre for Maritime Decarbonisation announced July 18 that it has successfully completed its final supply-chain trial for biofuel blended with very-low sulfur 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 greenhouse-gas abatement assurances for drop-in fuels. 

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 and Carbon Certification System GmbH standard, a multistakeholder certification scheme for biobased materials.

The biofuel component comprised neat fatty acid methyl ester (FAME), also known as biodiesel, 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 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 predetermined points along the supply chain to assess quality per EN 14214 and ISO 8217 standards. 

With well-to-wake emissions of 13.74 gCO2e/MJ, the neat FAME presented an 85.4 percent emissions reduction compared to the emissions of the fossil marine fuel.

The reduced emissions comply with the MEPC 80, which requires a minimum emissions reduction of 65 percent in order for biofuels to be classified as sustainable.  

GCMD and Hapag-Lloyd determined that consumption of the 4,500 metric tons of B30 resulted in 27.9 percent emissions reduction compared to sailing on VLSFO. 

A newly developed tracer deployed with this supply chain  

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. 

Development of biofuels assurance framework underway 

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 optimization 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 this year. 

“Over the past 18 months, GCMD has meticulously conducted these supply-chain trials of biofuels use under business-as-usual conditions, collaborating with partners to test different tracing techniques,” said GCMD CEO Lynn Loo. “The aim is to remove adoption barriers and increase user confidence and uptake of biofuels by assuring users that they are getting value for the cost premium, mitigating fears of biofuels adulteration, and preventing fraud.” 

Arne Maibohm, the director sustainability at Hapag-Lloyd, added, “We are delighted to have partnered with GCMD and BP in this important trial. The deployment of the new tracer technology is a good step forward in ensuring the integrity and authenticity of the biofuel supply chain. It enhances trust by verifying the origin of the biofuels. Hapag-Lloyd is dedicated to exploring innovative solutions to drive positive change within the industry.”
