2. 2 Some ideas for Marine supper gear Gas fuelled ships Major engine manufacturers have been delivering engines capable of running on natural gas for some time; But the implications for an industry-wide take-up of this technology are immense; could result in a 30% reduction in CO2 and 85% cut in NOx due to the high air/fuel ratio and no SOx at all. could also potentially save 45% on total operational costs. low volumetric density means that large tanks would need to be developed in order to run equivalent distances to conventionally fuelled ships.

3. 3 Some ideas for Marine supper gear Fuel cells The much debated benefits of fuel cell technology are greatest when the cell is operated on high purity hydrogen and oxygen. very low volume density requiring unfeasibly large storage tanks, make it highly unlikely that hydrogen will be a viable marine fuel in the near future. A much more realistic scenario for near term development is a natural gas cell. fuel cell technology using methane as fuel?

4. 4 Some ideas for Marine supper gear Air lubrication use of air under a ship’s keel to reduce drag. While the technical concepts vary, the basic idea of pumping air under a ship’s keel to reduce friction has the potential to offer significant cost and efficiency savings. The long term prospects of this technology are undeniably impressive.
