A REPORT prepared by Lloyd's Register (LR) and the University Maritime Advisory Services (UMAS) for the Sustainable Shipping Initiative (SSI) has found that the most cost-effective alternatives to fossil fuels for the maritime industry will be hydrogen fuel cells, electric power and advanced biofuels by 2030.
The study found that advanced biofuels are likely to be the most economically feasible alternative fuels in future. The ability to use them in a similar fashion today, such as through internal combustion means that additional costs are kept low and the cost of running a ship using biofuel will likely be down to the cost of the fuel itself.
But the sustainability of biofuels is questioned as non-food derived advanced biofuels will be required if they are to replace traditional shipping fuel. Biofuels may be needed for other energy consumers and may limit their availability.
For hydrogen, the cost of the technology onboard appears not to be profitable. However, the report suggests that if the development of the technology is encouraged by other industries or there are policy changes then it may become a more viable propulsion method, reported London's Vessel Performance Optimisation journal.
Hydrogen could also be used to produce ammonia, which is less expensive to store on board. Hydrogen and ammonia can be used in internal combustion engines to control capital costs.
Voyage costs are the largest contributory factor to the poor competitiveness of hydrogen fuel cells and post-2030 excess voyage costs may be able to be passed on to the supply chain due to the use of renewable energy throughout other industries.
