Port of Seattle’s 10-year deal with Carnival includes biofuel demonstration project

The Port of Seattle Commission on Tuesday (25 June) said it approved a 10-year preferential berthing agreement with Carnival Corporation, which includes a biofuel demonstration project. 

The long-term agreement supports the Port’s path to work with partners to achieve its zero-emission sustainability goals, along with providing local economic development opportunities and boosting the economic impact of cruise in the region.

The agreement sets a 10-year term (2024 – 2033), with a mutually agreeable option to extend for five more years (2034 – 2038). 

The agreement builds on prior agreements between the Port of Seattle and Carnival Corporation, adding ambitious environmental, sustainability, and social dimensions that benefit the greater Seattle region and helping to accelerate work underway.

Key elements of the long-term agreement in support of economic investment and sustainability includes:

  • Piloting the use of biofuel in cruise ship operation: The Port and Carnival Corporation will collaborate on a non-fossil fuel demonstration project and study to identify the end-to-end challenges and opportunities for using sustainable maritime fuels at scale in Seattle. The learnings will support other work in the sector to transition to alternative fuels.
  • Bringing in an anticipated USD 186 million in revenue and a minimum 550,000 revenue passengers annually: This would be the total anticipated revenue over 10 years; it could grow to $273 million if extended to the full 15 years.
  • Advancing the Port’s 2027 shore power goals: Carnival Corporation has been the leader on shore power in Seattle, having installed the equipment almost 20 years ago. To help the Port realize its ambition to have all ships at all cruise berths plug in by 2027, Carnival Corporation will seek commercial agreements with other cruise companies to plug in their ships to Carnival Corporation’s shore power assets at Terminal 91. The company’s vessels represented 100% of the shore power connections at the Port of Seattle in 2023, with 102 vessel calls.
  • Developing a responsible sourcing pilot program: Carnival Corporation will accelerate its local sourcing efforts to partner with local suppliers. Working with the Port, it will develop a pilot program for Seattle that promotes and supports small, diverse, disadvantaged, local, and tribal suppliers. Notably, the pilot program will also focus on building the capability of key suppliers to help create benefits beyond cruising.
  • Promoting overnight stays in Seattle surrounding cruise reservations: Carnival Corporation’s cruise lines will seek ways to further promote and encourage their guests to stay in Seattle before and after their cruise to help drive greater economic impact for the city and region.
  • Supporting educational and workforce development with maritime not-for-profits: Carnival Corporation will build on existing relationships by working with educators to support curriculum development, experiential field-based learning opportunities, and internships where appropriate to help build the maritime workforce pipeline in the region.

Evos Rotterdam starts construction on methanol and ethanol expansion project

Evos Rotterdam on Thursday (25 June) said it has held the ground-breaking ceremony for its methanol and ethanol expansion project at the Port of Rotterdam, formally starting the construction phase of a major investment in additional terminal capacity.

The project comprises five new storage tanks with a combined gross capacity of 67,500 cubic metres, a new pump station and a new jetty, developed in close cooperation with the Port of Rotterdam. 

Once operational in early 2028, the expansion will give Evos Rotterdam greater capacity to handle methanol and ethanol for industrial customers, as well as for the developing market in cleaner, low-carbon marine fuels and bunkering.

Daan Vos, CEO of Evos, said: “This ground-breaking ceremony is the starting point for the construction phase of a project that has required close cooperation, technical focus and long-term commitment. 

“I would like to thank the Port of Rotterdam, our contractors and all project partners who joined us and who have helped bring the project to this stage. 

“This expansion strengthens Rotterdam’s position in methanol and ethanol logistics, including low-carbon methanol, and gives our customers the capacity they need as markets continue to change.”

Christiaan Kop, Managing Director Evos Rotterdam, said: “Thank you to everyone who joined us to officially start this project. It was a strong beginning for an excellent project. 

“I would also like to thank the project team for helping to organise the ceremony so well. The team has shown the professionalism and confidence this project deserves.”

ICS report: LNG and biofuels seen as most viable marine fuels over next decade

This was followed closely by HFO combined with abatement technologies while methanol ranked in fourth place, according to ICS’s new Maritime Barometer Report.

A new report by the International Chamber of Shipping (ICS), published on Tuesday (23 June) found that  LNG and biofuels are seen as the most viable marine fuels over the next decade.

This was followed closely by HFO (Heavy Fuel Oil) combined with abatement technologies while methanol ranked in fourth place. 

The report found that in 2025 to 2026, maritime leaders are displaying a preference for traditional fuels that have established supply mechanisms. 

The ICS Maritime Barometer Report 2025–2026 surveyed C-suite level leaders, shipowners, and operators worldwide to identify the key risk areas shaping shipping. 

Despite slight decline, LNG shared top spot with biofuels as one of three most viable future fuels over the next decade. 

LNG maintained its position as a joint leading fuel in the Barometer, with roughly 51.35% of leaders naming it as one of the most viable fuels over the next decade. 

“This is despite a marginal softening in sentiment amongst maritime leaders compared to last year’s survey, reflecting its continued role as the most immediately scalable alternative within the current fuel mix,” the report said. 

However, the report noted that this positioning is increasingly shaped not just by infrastructure maturity, but by how geopolitical instability translates into fuel-specific perceptions of security, routing exposure, and price volatility across global trade flows.

This is particularly evident in Asia-Pacific and the Middle East, where LNG’s role is reinforced through continued investment in import and bunkering infrastructure.

Singapore remains the world’s leading LNG bunkering hub, supported by expanding small-scale supply chains and vessel availability, while South Korea and China are rapidly scaling receiving and bunkering capacity to support both shipping and power demand growth.

Biofuels record one of the sharpest increases in sentiment across the future fuels landscape to match LNG at 51.35% in this year’s report.

“This could reflect a shift driven less by structural conviction and more by operational response to heightened uncertainty in global energy and trade systems,” it said. 

Their growing prominence could be closely linked to the increasing attractiveness of low-friction compliance options in a context where alternative fuels remain constrained by uneven infrastructure development, fragmented regulatory alignment, and delayed capital deployment across key regions.

Compared with LNG, which is shaped by infrastructure lock-in and geopolitical price exposure, biofuels offer immediate operational flexibility.

Japan has emerged as a key driver of marine biofuel adoption, with government-backed trials involving major shipping lines such as NYK testing biofuel blends on international routes. China has also expanded pilot programmes using biodiesel and waste-derived fuels in coastal shipping, reflecting a pragmatic approach to emissions reduction in regional trade flows.

ExxonMobil completes first sea trial of bio bunker fuel blend made from FAME

US oil major ExxonMobil on Tuesday (23 June) said it has successfully supplied a B30 0.50% sulphur marine residual fuel blend (B30 VLSFO), made using fatty acid methyl ester (FAME) Distillation Residue, to Wallenius Wilhelmsen. 

The bio marine fuel blend was bunkered by the vehicle carrier Titus in Zeebrugge ahead of the sea trial, marking a significant milestone in ExxonMobil’s journey towards supplying the marine industry with lower GHG emission fuels. 

The B30 VLSFO fuel meets the RMG380 residual fuel oil classification and complies with ISO 8217:2017 with the exception of the bio blend component. It shares similar drop-in properties to a B30 VLSFO made with FAME produced from used cooking oil (UCOME). 

The fuel has the potential to reduce lifecycle GHG emissions compared to conventional fuels. 

Importantly, marine fuels made with FAME Distillation Residue have a major advantage over FAME itself, as there is currently no competition for this material from other transport sectors. 

Additionally, when compared to FAME in VLSFO blends, several key properties of the FAME Distillation Residue are closer to the VLSFO component, such as density and viscosity. This is beneficial as users will see a lower reduction in viscosity than that of a FAME in VLSFO blend, which makes it comparatively easier to handle onboard ships. Further, extensive lab testing has shown good compatibility between petroleum-based VLSFOs and this B30 VLSFO made with FAME Distillation Residue. 

The sea trial was successfully completed with no operational concerns. The B30 VLSFO batch was bunkered without issue. The onboard storage and handling of B30 VLSFO did not result in any filtration or purification issues. Engine performance remained stable, as confirmed by comparing key parameters recorded in the performance and condition monitoring reports before, during and after the trial. 

“This successful sea trial highlights a practical, cost-effective pathway for customers to reduce their lifecycle greenhouse gas emissions while maintaining operational performance. By leveraging FAME Distillation Residue, ExxonMobil can offer a drop-in solution that supports compliance with evolving EU regulations and helps operators advance their lower GHG emission goals confidence,” said Gideon Simmelink, Account Manager Marine Fuels, ExxonMobil. 

“Wallenius Wilhelmsen has a long-standing collaboration with ExxonMobil. This trial supports our efforts to assess new fuel options and advance our decarbonization ambitions,” said Kari Haugen, Senior Manager Energy Sourcing, Wallenius Wilhelmsen. 

Subject to regional availability, ExxonMobil offers a range of bio marine fuel blends (Bio VLSFO, Bio ULSFO, Bio MGO and Bio HSFO), which we have supplied into the ARA (Amsterdam-Rotterdam-Antwerp) region (VLSFO and USLFO), the UK (MGO and HSFO) and Singapore (VLSFO). 

These solutions are designed to help meet the diverse needs of the shipping industry while helping support GHG emission reductions. Always consult with engine manufacturers as OEMs may limit bio blend percentages or specific bio components for certain engine designs.
