United Kingdom | November 24, 2025 – ExxonMobil, a leading global supplier of marine fuels and lubricants, is supplying bio marine fuel blends across UK South Coast ports. Building on its pioneering operations in the Amsterdam–Rotterdam–Antwerp (ARA) region and Singapore since the early 2020s, the company provides reliable lower-emission fuel options for coastal and international shipping, contributing to the maritime sector’s decarbonisation efforts.

Bio Marine Fuel Blends and Their Role in Bunkering
As global shipping accelerates its decarbonisation efforts, bio marine fuel blends have emerged as one of the most practical near-term options for reducing lifecycle greenhouse gas (GHG) emissions. Unlike fuels requiring new vessel designs or onboard retrofits, bio blends integrate directly into established bunkering operations.
These fuels are generally supplied as drop-in solutions, meaning:
- No engine modifications are required
- No changes to onboard storage or handling systems
- Bunkering procedures remain unchanged
- Operational continuity is maintained
When used within OEM-approved blend levels, bio marine fuels can provide measurable well-to-wake GHG reductions, making them an important contributor to meeting IMO and regional requirements such as FuelEU Maritime.
For bunker suppliers, bio blends act as a critical bridge fuel, delivering lower-carbon options while utilizing existing storage, supply chains, and logistics networks.
Global Expertise Brought to the UK
ExxonMobil’s activity in the UK is underpinned by its extensive experience supplying marine biofuel blends in two of the world’s leading bunkering hubs since the early 2020s:
- Amsterdam–Rotterdam–Antwerp (ARA): VLSFO B30 and ULSFO B25
- Singapore: VLSFO B24
This established operational record demonstrates fuel stability, compatibility, and performance across international shipping routes and provides the foundation for consistent supply in the UK bunker market.
“As global shipping accelerates its decarbonisation efforts, bio marine fuel blends have become one of the most practical near-term options for reducing lifecycle greenhouse gas (GHG) emissions, Bio blends continue to be one of the most accessible transitional fuels—supported by existing engines, bunkering infrastructure, and global regulations.“
Supplying Bio Marine Fuel Blends Across the UK South Coast
ExxonMobil now supplies its bio marine fuel blends across several key UK South Coast ports, including:
- Plymouth
- Portland
- Poole
- Southampton
- Portsmouth
ExxonMobil’s current UK offering provides flexible, high-percentage bio-blends:
| Fuel Type | Sulphur Content | Max Bio Component | Use Case |
| Bio MGO | 0.10% (Low Sulphur) | B30 (30%) | Coastal, ECAs, and engines requiring distillate fuel. |
| Bio HSFO | 3.5% (High Sulphur) | B30 (30%) | VLSFO-equivalent for vessels with scrubbers. |
Both can be supplied with up to 30% bio component (B30), depending on customer needs and engine manufacturer guidance. This gives shipowners reliable access to lower-emission fuels across a strategically important stretch of the UK coastline that serves coastal shipping, ferries, offshore operations, container carriers, and international trade routes.
Why Bio-Blends Matter Now
- Compliance with IMO and FuelEU: Bio-blends enable measurable well-to-wake GHG reductions, helping operators meet increasingly stringent regulatory frameworks.
- Minimal Operational Disruption: Bio blends use existing infrastructure and supply systems, avoiding costly retrofits or alternative fuel conversions.
- Scalability: Bio marine fuels offer the most readily deployable lower-carbon option for fleets navigating the transition toward cleaner energy.
The availability of B30 fuels across the UK South Coast gives shipowners a practical tool to maintain operational continuity while progressing toward mandated emissions targets.
Supporting the Maritime Transition
The supply of bio marine fuel blends in the UK aligns with the industry’s broader shift toward scalable and flexible lower-emission solutions. Bio blends remain one of the most accessible transitional marine fuels, supported by existing engines, bunkering infrastructure, and evolving global regulations.
By ensuring consistent supply across these ports, ExxonMobil reinforces its long-standing role in the marine energy sector and strengthens the availability of practical lower-carbon options for shipowners operating in and around the UK.
About ExxonMobil
Exxon Mobil Corporation (ExxonMobil) is one of the world’s largest publicly traded international oil and gas companies, with a vertically integrated structure spanning energy and chemical industries. The company was formed in 1999 through the merger of Exxon and Mobil, both successors of John D. Rockefeller’s Standard Oil.
ExxonMobil operates across three main divisions:
- Upstream: Exploration and production of crude oil and natural gas, with key projects in the Permian Basin (US), Guyana, Brazil, and major LNG developments in Qatar and Mozambique.
- Product Solutions: The largest integrated downstream and chemical business globally, producing fuels, lubricants (including the Mobil™ brand), and a wide range of petrochemical and specialty products.
- Low Carbon Solutions (LCS): Focused on developing and scaling lower-emission technologies, including Carbon Capture and Storage (CCS), hydrogen, and lower-emission fuels such as bio marine fuel blends.
Through this structure, ExxonMobil combines global scale, integrated operations, and technology to support energy supply while advancing lower-carbon solutions for the maritime and broader energy sectors.
