Lloyd’s Register explores new technologies to help reduce marine fuel consumption
Fuel cells will be a long term sustainable energy solution for ships but, for immediate fuel savings, reduced environmental impact and reduced operational costs, many options are available now for incorporation in new designs
At SMM Istanbul, Lloyd's Register explored in detail the potential use of new technologies to help in reducing both marine fuel consumption and greenhouse gas (GHG) emissions. Dr. Zabi Bazari, Ship Energy Services Manager for Lloyd's Register Marine Consultancy Services, said that energy savings as high as 40% can be achieved by incorporating new systems and approaches into the design of new ships.
Looking ahead, he said that fuel cells could eventually become the main energy unit in commercial ships when low-carbon technologies and renewable sources of energy are firmly in place.
In his speech, Zabi reviewed existing and potential technologies in two main categories: hull and propulsors; and engines and auxiliary machinery.
Ralph Olingschlaeger, a member of the Marine South East Innovation Group believes that despite the current economic climate new low carbon technologies that reduce marine fuel consumption and greenhouse gases are continuing to move forward. South East companies and Universities are playing a key role in this progression.
He commented: "whilst fuel cells, either used as auxiliary power units replacing internal combustion engine generators within 10 years or main propulsion units (10yrs plus) continue to be regarded by many as the engine of the future, there are a number of stepping stone technologies that can move us towards a low carbon technology."
The South East is well placed in the development of fuel cells with some of the leading fuel cell developers and academic institutions, such as Southampton University and Isle of Wight-based Hybrid Marine Ltd, being based here.
Ralph went on to say "the obvious easy win and first step is to use less energy. This could be through improved hull design, specifying more efficient equipment or increasing the use of smart technology linked to on-board systems monitoring. This is another key strength in the South East.
"We will also find that the use of alternative fuels such as biofuels, ethanol or methanol as an energy carrier will help alongside existing wind and solar power. An early win, especially in the leisure marine sector are hybrid drive systems such as the highly innovative system developed by Hybrid Marine Ltd."
