Marine fuels supplier in the Nordics, Stena Oil, on Friday (27 October) said it carried out a bunkering operation to Dalaro Shipping's Oslo Wave 3, a 17,485 DWT cargo vessel, on 26 October.

Stena Oil said the bunkered B25 fuel is composed of 25% rapeseed methyl ester (RME) and 75% marine gasoil. 

“We recognize the growing significance of sustainability within the shipping industry, particularly considering tightening emission regulations. Providing a wide variety of alternative fuels is therefore a significant aspect for us and our customers,” it said in a statement.

Jenny Eriksson, Bunker Trader at Stena Oil, said: "As sustainability concerns gain momentum within the shipping sector and emissions regulations become more stringent, the necessity of diversifying fuel alternatives beyond traditional selections takes on added significance. Consequently, we anticipate a steady growth in the biofuels market.”

Nils Östman, Head of Operations at Dalaro Shipping, said: "Dalaro is, together with our head owner Oslo Bulk, very focused on reducing our GHG emissions. The usage of biofuel and other types of alternatives to conventional bunker fuels heralds a crucial step toward a sustainable maritime future where vessels can navigate with a much lower carbon footprint.”

“Conducting this biofuel trial is one of several important steps Dalaro is taking to prepare our vessels for the future.”

United European Car Carriers (UECC) recently announced its progress of using alternative bunker fuels and said it was on track to exceed its goal of a 45% emissions reduction by 2030 after more than doubling biofuel usage across its fleet last year.

UECC boosted the use of ISCC-certified sustainable biofuel B100 on both owned and time-chartered ships to 14,000 metric tonnes (mt) last year, up from 6,500 mt in 2022.

The company achieved a total tank-to-wake emissions reduction of over 60,000 tonnes across its 14-vessel fleet in 2023, of which it is estimated increased biofuel use accounted for 40,000 tonnes, with the remainder coming from LNG. This was a near-250% increase on the emissions cut of 24,200 tonnes achieved in 2022.

TheEuropean sustainable shortsea carrier said it has made significant strides in decarbonisation of its fleet of pure car and truck carriers (PCTCs) with the addition of five LNG-fuelled newbuilds and the increased rollout of biofuels in recent years - and this is now showing commercial payback for clients in the light of new green regulations, according to Energy and Sustainability Manager Daniel Gent.

“Consequently, we are well on the way to reach or exceed our 45% emissions reduction target by 2030. This clearly has a positive impact for those bio-supportive cargo owners in terms of reducing costs related to the EU Emissions Trading System (EU ETS),” Gent said.

“Furthermore, 85% of the vessels in our fleet achieved a C-rating last year with the IMO’s Carbon Intensity Indicator (CII) and this year we expect all our ships to achieve this rating or above.”

Gent also pointed out the UECC fleet is already in surplus in relation to the requirement for an average 14.5% reduction in GHG intensity by 2035 under the FuelEU Maritime regulation due to be implemented next year.

The environmental performance of UECC’s current fleet of nine owned and five time-chartered PCTCs has been enhanced through delivery over the past seven years of five eco-friendly newbuilds - a pair of dual-fuelled LNG vessels and trio of multi-fuel LNG battery hybrid units.

The use of LNG reduces emissions of CO2 by around 25%, SOx and particulate matter by 90% and NOx by 85%, while the latest battery hybrid newbuilds exceed the IMO target to reduce carbon intensity by at least 40% from 2008 levels by 2030.

UECC is now looking at sourcing alternative carbon-neutral fuels such as bio-LNG and e-LNG for these vessels to further improve their green performance, according to Gent.

UECC’s adoption of alternative fuels has expanded exponentially since the programme was launched in 2020 with piloting the use of biofuel on its vessel Autosky, bolstered by valuable support from owners of its time-chartered vessels, clients such as BMW, fuel suppliers like GoodFuels, industry partners, and parent companies NYK and Wallenius Lines.

“We are now in the fifth year of running our biofuels programme and it has gone from strength to strength. UECC has sought to take a leading role through early-stage analysis of new biofuels to evaluate their potential in terms of technical suitability, sustainability and commercial viability, both  to deliver the best solution for our customers and give the sector a blueprint for assessment and adoption of such fuels based on these three pillars,” Gent explained.

He added that, in terms of sustainability criteria, the company looks for biofuels with the biggest environmental impact, with a typical minimum 90% reduction in GHG intensity from well-to-wake compared with conventional marine fuels. 

UECC has steadily expanded the use of green fuels to cover 30% of its fleet in 2023, up from 18% in 2022, and is on track to achieve 50% coverage this year towards the goal of 80% by 2030, though Gent is confident of surpassing this figure.

He said being proactive in trialling new alternative fuels has also promoted engagement with fuel providers, which has led to UECC’s latest initiative together with biofuel supplier ACT Group as part of an industry collaboration to test the Cashew Nut Shell Liquid (CNSL)-based biofuel FS.100 that he believes has “great potential for sustainable shipping”.

“Increasing the pool of sustainable drop-in fuels offers a pathway for shipping to achieve rapid emissions cuts on existing vessels. Combining alternative fuels with energy efficiency measures such as hull cleaning and electrification with shore power can further accelerate decarbonisation,” Gent said.

“By progressively advancing the use of alternative fuels, we are reducing emissions exposure for our clients and securing regulatory compliance long into the future, while also promoting industry efforts to reach the net-zero goal,” he concluded.

Singapore: GCMD studies FAME biofuel degradation in commercial and storage conditions

The Global Centre for Maritime Decarbonisation (GCMD) on Tuesday (18 June) announced the release of its latest report,aimed to shed light on its findings from tracking the quality of FAME and FAME blends as they make their way through the supply chains and on consumption onboard vessels.

GCMD said Fatty Acid Methyl Esters (FAME), a readily available biofuel, is gaining attention as an immediate solution to comply with EU and IMO regulations.

FAME use in major bunkering hubs Singapore and Rotterdam has risen from being negligible in 2020 to a combined 1 million metric tonnes (mt) of FAME blends in 2023.

“Unlike conventional marine fuels, FAME-based biofuels can be unstable since its natural oils and fats can slowly oxidise when exposed to atmospheric oxygen,” it said. 

When oxidation happens, FAME can degrade to produce by-products, like peroxides, alcohols, and sludge, all of which can impact engine life and performance. Degradation can also be further accelerated by exposure to water, impurities, contaminants, light, and heat.

The report, titled Tracking the propensity of biofuels degradation across the maritime supply chain, sheds light on a crucial question: Does FAME degrade significantly under actual commercial and storage conditions in the marine supply chains, hindering its potential as a widespread decarbonisation solution?  

Key insights and takeaways

 Encouragingly, GCMD said end-to-end supply chain trials detected no significant degradation of FAME under commercial operations conditions.

“These findings offer strong support for FAME use in the marine fuels supply chain,” it said. 

The report elaborates how the team traced the properties of FAME and FAME blends, and tracked the parameters of FAME quality, namely acid value, viscosity, FAME content, energy content and microbial contamination, of samples at different points along the supply chain to come to this conclusion.

What the report covers

  • Understanding the propensity of degradation of FAME
  • Tracing FAME quality in GCMD’s end-to-end supply chains
  • Understanding the current ISO specifications for FAME quality requirements
  • Contextualising GCMD’s findings per ISO specifications

The report is co-authored by Dr. Prapisala Thepsithar, Director of Projects, and Dr. Sanjay Kuttan, Chief Strategy Officer, at GCMD. 

It has also been reviewed by industry leaders: Dr. Malcolm Cooper, CEO of VPS, Captain Rahul Choudhuri, President, Strategic Partnerships, VPS and Ms. Monique Vermeire, Fuels Technologist at Chevron.

In a social media post, Capt. Rahul Choudhuri, President Strategic Partnerships, said: “VPS is very proud to have supported the Global Centre of Maritime Decarbonization (GCMD) in this vitally important work of understanding the nature of Biofuels Degradation.”

VPS said the biofuels study showed levels of fuel degradation in a real-world environment. Whereas the trials indicated no degradation of the Biofuels over the nominated transportation section & supply to the vessel
