ExxonMobil completes successful sea trial of its 1st marine bio fuel oil

ExxonMobil has completed a successful sea trial of the company's first marine bio fuel oil with shipping company Stena Bulk, bunkered in the port of Rotterdam. The marine bio fuel oil is a 0.50 percent sulfur residual-based fuel (VLSFO) processed with a second-generation waste-based fatty acid methyl ester (FAME) component (ISCC-certified). The bio fuel oil will be available later this year, initially in Rotterdam, the Netherlands, before wider launch across the ExxonMobil port network.

The sea trial also demonstrated that the marine bio fuel oil, which can provide a CO2 emission reduction of up to approximately 40 percent compared with conventional marine fuel can be used in a relevant marine application without modification and can help operators take a significant step towards meeting their carbon emissions reduction targets. This also supports the International Maritime Organization's ambition to reduce total annual greenhouse gas (GHG) emissions from international shipping by 2050.

The marine industry recognizes the GHG reduction benefits of bio fuel oil, and the fuel meets requirements for global sulfur cap compliance and has undergone critical and extensive testing. The sea trial undertaken with leading shipping tanker operator Stena Bulk was designed and completed as part of ExxonMobil's assessment and trial protocol to demonstrate that there were no adverse equipment effects when operating with higher levels of bio components.

"With new marine fuels coming to market recently, the need for quality fuels that are both reliable and ISO-compliant has never been greater," said Cowan Lee, marine fuels marketing manager at ExxonMobil. "ExxonMobil's new marine bio fuel oil meets that growing need as it has been extensively tested, is sulfur-compliant and can make a significant contribution in helping operators reduce their CO2 emissions. As operators face increasingly stringent regulations and significant pressure from customers to demonstrate their commitment to reducing GHG emissions, this is an important next step in providing the lower-emissions fuels that operators want and need."

The Stena Bulk sea trial was carried out while the vessel was in commercial operation. The trial included evaluation of onboard storage, handling and treatment, and the fuel was consumed in engines and other machinery onboard.

"We believe biofuels have an important role to play in accelerating the reduction of greenhouse gas emissions in shipping," said Erik Hånell, president and CEO of Stena Bulk. "The development of ExxonMobil's biofuel is an important step towards a broader commercial use of low-carbon fuels and we were happy to be part of the sea trial, which proved to be very successful. The fuel performed very well and fitted seamlessly into our technical and commercial operation without the need for engine modifications or additional procedures, while contributing to a significant reduction of CO2 emissions."

John Larese, marine fuels technical advisor at ExxonMobil, added, "As a residual fuel, it can be dropped-in without the need for expensive modification and can help provide ship operators immediate CO2 savings compared to full hydrocarbon fuel. This successful trial also involved close collaboration with the OEMs, the vessel's classification society and flag state."
