Odfjell has made significant strides towards sustainable shipping with the successful completion of the Bow Olympus’ first near carbon-neutral transatlantic voyage. This journey utilized a combination of wind-assisted propulsion and 100% sustainable biofuel, demonstrating how modern technologies and fuels can work together to help deep-sea shipping reduce its carbon footprint. Real-time data collected during the voyage has shown that this dual propulsion method is not only technically viable but also environmentally impactful. The emissions from Bow Olympus during its journey meet the European Union’s 2050 Fuel Maritime GHG intensity targets and comply with the International Maritime Organization’s standards at least until 2044.
The vessel is equipped with four 22-meter suction sails, which have performed admirably under various weather conditions. Erik Hjortland, VP of Technology at Odfjell, noted that the energy savings from the sails have exceeded expectations, with fuel consumption reduced by 15-20%, leading to a daily savings of five tons of fuel. In some areas, fuel consumption improvements reached as high as 40%. In conjunction with wind propulsion, Odfjell incorporated biofuel sourced from certified sustainable waste materials for the voyage.
This combination achieved an impressive 85% reduction in greenhouse gas intensity compared to conventional fuels. The achievement signals a plausible pathway to carbon neutrality for deep-sea shipping, potentially years ahead of existing targets. Odfjell has a history of enhancing fuel efficiency through energy-saving devices, improving carbon intensity by over 53% since the 2008 IMO baseline. Now, as they aim to reduce carbon intensity by 57% by 2030, they remain open to exploring various fuels, ensuring adaptability in a rapidly evolving industry.
Hjortland expressed optimism about leveraging the insights gained from this voyage to further advance towards true carbon neutrality.
