Alternative Fuels for Shipping - DNV GL 2014


This Position Paper provides an overview of the possible alternative fuels for marine propulsion. Maritime transport accounts for over 80% of world trade by volume and for approximately 3% of global greenhouse gas emissions, while it is also a contributor to air pollution close to coastal areas and ports. In order to reduce the impact maritime transport has on climate change and on the environment, a number of fuel efficiency measures, both on technical and on operational levels, have to be adopted, including the introduction of alternative fuels. The immediate effect of introducing alternative fuels will be a strong reduction in SOx, NOx, and PM, while greenhouse gas reductions will also be possible, depending on what types of fuel are used. Fossil-based fuels, such as LNG will have limited contribution to greenhouse gas reductions, while biofuels have the potential to lead to drastic reductions. On a technical level, the introduction of alternative fuels will be accompanied by additional complexity, in the areas of fuel supply infrastructure, rules for safe use of fuels on board, and operation of new systems. It is expected that a number of different fuels may become important in different markets around the world, depending on local availability of fuels, which will add to the complexity. In this environment, the role of Classification Societies will become increasingly important, in order to ensure the safe handling of fuels in shipping.
