Greg Stanton, CEO of Aura Marine, emphasizes the importance of research and development (R&D) and lifecycle support in facilitating carbon reduction in the maritime fleet. Industry analyses show that nearly two-thirds of the global fleet will not have major upgrades for next-generation fuels due to the age of the ships and economic issues. For this significant segment, the industry needs solutions that provide measurable reductions in greenhouse gas emissions without operational risks or the need for capital commitments that are not justifiable.
Challenges of Alternative Fuels
Transitioning from conventional marine fuels is not simply a matter of swapping one product for another. Alternative fuels introduce real technical complexities that must be resolved before reaching the vessels. For example, methanol requires specific configurations of safety systems that include gas detection, leak detection, and emergency shut-off capabilities. Additionally, crew training that goes beyond managing conventional fuels is essential.
Ammonia also presents greater challenges, including additional configurations for tanks, separation from crew accommodations and heat sources, as well as specialized safety measures and extensive operational training. Even biodiesels, which are often considered an easy option, require careful consideration regarding viscosity, cold flow properties, and compatibility with existing equipment.
The Role of Biodiesels and Lifecycle Support
In a layered strategy, high flash point biodiesels have a stronger role in the near future. Fuels compliant with Chapter II-2 of the SOLAS Convention, such as HVO and FAME, can act as direct substitutes and require minimal modifications to existing engines and fuel supply systems. Additionally, under the EU ETS system and FuelEU Maritime, vessels visiting European ports face direct financial risks based on their greenhouse gas intensity.
As fuel specifications and regulatory requirements change, lifecycle services become essential to the value of any investment in carbon reduction. These services include commissioning, periodic service inspections, maintenance, and crew training. They ensure that the fuel supply system operates effectively throughout the operational life of the vessel and that the system can continue to function in the event of changes in fuel specifications or regulations.
