Drop-in replacements for fossil fuels may be a cost-effective way of meeting environmental regulations and could extend the life of older vessels, if barriers to adoption can be overcome, according to a new LR report.
As a low-emission alternative fuel with low-CAPEX investment and the potential to expand the operational lifespan of large portions of the world fleet, biofuels may have an important role to play in shipping’s decarbonisation, but feedstock availability and demand competition from other transport sectors pose challenges that will need to be addressed for widespread adoption, finds Lloyd’s Register’s (LR) new Fuel for Thought: Biofuel Report
The report points to biofuels as a path to compliance with environmental regulations for ships for which retrofits to adopt other future fuels are not economically feasible. As ‘drop-in’ replacements for traditional fuels, biofuels require minimal changes to machinery and operations and offer GHG emissions savings of up to 84% compared to traditional fuels.
The similarities between biofuels and their fossil equivalents, as well as the ability to blend biofuels with traditional fuels, makes adopting biofuels a comparatively straightforward process for shipowners compared to other alternative fuels. Biofuels are generally compatible with existing onboard machinery and fuel tanks, use the same bunkering infrastructure as fossil equivalents, and their similarity to traditional bunkers means training requirements for crew are minimal compared to other future fuels.
The report states that the main challenges for widespread deployment are availability and demand competition from other transport sectors, including aviation, and the investment in biofuel production capacity that will be needed to meet the growing demand from the transport sector. The price of biodiesel blends is expected to rise alongside blending levels as demand drives up feedstock prices.
Tim Wilson, Principal Specialist Fuels Lubes and Emissions. Lloyd’s Register said: “Biofuels are unique among the future fuels for shipping as the vast majority of the world fleet is equipped with engines that can use them. As a drop-in replacement for fossil fuels, biofuels are an available and affordable method of reducing carbon emissions in the short term without large capital investment. The range of biofuel trials across ship segments and biofuel types reflects strong interest from ship owners in their use onboard.”
Fuel for Thought: Biofuel gathers the most relevant information on the use of biofuels in shipping, serving as a convenient reference for shipowners considering alternative fuel options for their fleets and maritime professionals seeking a deeper understanding of the zero-carbon transition. The report combines expertise from LR and other shipping knowledge leaders on the characteristics and operational considerations for biofuels, regulatory drivers for biofuel adoption, techno-economic considerations, fuel quality and availability, and biofuel trials in shipping.
The report builds on the success of earlier Fuel for Thought reports, where LR creates a one-stop repository for relevant information on all alternative fuels for the maritime industry. It also contains information from LR’s recently updated Zero Carbon Fuel Monitor, an insight-based assessment of the readiness of biofuels and other zero-carbon fuels for maritime applications.
