Sustainable fuels for shipping
Book chapter, 2022

The International Maritime Organization (IMO) aims to reduce the total annual greenhouse gas (GHG) emissions from international shipping by at least 50% by 2050 compared to 2008 and to phase them out as soon as possible. Decarbonized shipping represents a considerable challenge since the GHG emissions are estimated to increase by 2050 in several scenarios [1]. Decarbonization of shipping is important and urgent, but at the same time it is also important to make sure that other environmental impacts and sustainability concerns will not increase as a result. It is important to have a wide
systems perspective when searching for solutions so that a sustainable shipping industry can be reached considering environmental, social, and economic dimensions and following the UN Sustainable Development Goals. This chapter starts by defining fuel, energy carriers, and primary energy sources in
Section 9.2 followed by a description of the main primary energy sources that can be used to produce sustainable shipping fuels in Section 9.3 and potential energy carriers for ships in Section 9.4. Section 9.5 describes some of the pros and cons of different future fuels for shipping against technical, environmental, economic, and other criteria. Final reflections on how to choose future fuels are presented in Section 9.6.
