The marine biofuel oil - described as a 0.50% sulphur residual-based fuel (VLSFO) processed with a second generation waste-based FAME component (ISCC certified) – will be available later this year at Rotterdam before a wider roll-out across ExxonMobil’s port network.
The sea trial, which was undertaken with Stena Bulk with a bunkering operation at the Port of Rotterdam, is said to have demonstrated that the marine biofuel oil can achieve a CO2 emission reduction of up to 40% compared with conventional bunker fuel. This benefit is compared to conventional petroleum-based VLSFO, calculated on an energy basis. ExxonMobil notes that the well-to-wake CO2 emissions reduction has been calculated using Directive 2009/30/EC of the European Parliament and of the Council Annex IV C. 1 and MEPC 66/21 Annex 5.
The sea trial is 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, commented 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 sulphur compliant and can make a significant contribution in helping operators reduce their CO2 emissions.’
He continued: ‘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 on-board storage, handling, and treatment and the fuel was consumed in engines and other machinery on-board.
‘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 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.’
