Marine Biofuel: The future of sustainable shipping
Biofuel is emerging as a promising alternative to traditional fossil fuels in the shipping industry, offering a potential pathway to reduce greenhouse gas emissions and advance towards a more sustainable future.
The maritime sector is exploring a wide variety of biofuels, including Fatty Acid Methyl Esters (FAME), hydrotreated vegetable oils (HVO), biomass-to-liquid (BTL) products, glycerol, and straight vegetable oil (SVO) products. These biofuels can be used in concentrations up to 100% (B100) or as substantial blend components with residual-type products.
Biofuel ships: navigating the seas with renewable energy
Biofuels are considered technologically ready for deep-sea shipping, as they can be used as drop-ins or blends with minor modifications to existing engines, machinery, and storage systems. This simplifies the transition from existing fossil-derived fuels. However, biofuels have also sparked controversy, with questions raised about their sustainability impacts and whether they will be available in sufficient quantities to meet the needs of different sectors.
Green biofuels: A sustainable alternative for the maritime industry
The potential of biofuels in shipping is being explored to assess their viability and impact on decarbonisation. As the shipping industry continues to navigate towards a cleaner future, biofuels stand out as a key area of focus, balancing the need for environmental sustainability with the practicalities of technological readiness and availability.

Frequently Asked Questions
Biofuels are used in shipping as an alternative to conventional fossil fuels to reduce greenhouse gas emissions and reliance on non-renewable energy sources. They can be blended with traditional marine fuels or used in modified engines designed to handle biofuel properties.
Biofuel can be used in ships. Biofuels, such as FAME biodiesel (Fatty Acid Methyl Ester), can be blended with traditional marine fuels or used in specially designed engines, offering a renewable alternative to reduce carbon emissions in maritime transport.
The future of biofuels for shipping looks promising as advancements in production technology make them more viable. They offer a renewable alternative to fossil fuels, potentially reducing carbon emissions and helping the maritime industry meet environmental regulations. Also, they are considered “drop in” fuels, meaning they need no, or little, modification to conventional engines, only certain adjustments are needed to be made. Concerns around future availability of sustainably sourced feedstock are limiting scale-up of biofuels in shipping.
Common biofuels used in transportation include FAME biodiesel (Fatty Acid Methyl Ester) and Hydro-treated Vegetable Oil (HVO). FAME is produced through the transesterification of fats or oils, while HVO is created by hydrogenating vegetable oils. These fuels can be used in modified engines or blended with conventional fuels for use in shipping.
- Transportation: Biofuels are used in vehicles as a cleaner alternative to gasoline and diesel.
- Electricity Generation: Biofuels can be burned to produce electricity in power plants.
- Heating: Biofuels are used in heating systems for residential and industrial purposes.
Hydro-treated Vegetable Oil (HVO) can be used in ships. HVO is a renewable diesel produced from vegetable oils or animal fats, offering a cleaner alternative to conventional marine fuels and compatible with existing diesel engines with minimal modifications.
Biofuel can partially replace petrol and fossil fuels. However, fully replacing petrol with biofuel would require significant advances in production capacity, engine compatibility, and infrastructure.
The biggest challenges in adopting biofuels in shipping are the high production costs, which makes them less competitive with fossil fuels, and limited availability of resources.
Biofuel is expensive due to the costs associated with feedstock production, processing, and conversion technologies.
Biofuel has a shorter shelf life than fossil fuels, typically lasting 6 to 12 months before degradation. Proper storage conditions, such as cool, dry environments and the use of stabilisers, can extend its lifespan.
