Market penetration by alternative fuels have already begun with ship builders, engine manufacturers and classification bodies by introducing greener ships running on cleaner fuels. This can be attributed in large part to the MARPOL (International Convention for the Prevention of Pollution from Ships) regulations in place since the 1970s and progressively more stringent emission standards subsequently introduced by national legislators. This exploratory report gives an overview of the marine sector, including market share, emission related issues, fuel standards and present legislation. It then considers different alternative fuels, engine types and the introduction of alternative fuels. Low sulphur grade diesel fuels which are available at a higher price than traditional fuel, and possibility of using a scrubber to reduce emissions such as oxides of sulphur (SOx) on ships that run on traditional fuels are also discussed. The report then reviews biofuels such as biomethanol, dimethyl ether (DME), biodiesel, hydrogenation derived renewable diesel (HDRD) and algal biofuel. Of these, methanol has been put into commercial use, although so far derived from fossil sources, to fuel the large Stena Germanica ferry in the Baltic Sea. Among the gaseous fuels, LNG (liquefied natural gas), Bio-LNG and LPG (liquefied petroleum gas) have been discussed. The report also considers electricity (battery operated), FT-diesel (Fischer-Tropsch diesel), pyrolysis oil, hydrogen in combination with fuel cells, solar power and wind energy as potential alternatives. At the moment, LNG and methanol seem to be the most promising alternatives with good market supply infrastructure in place. The sustainability of producing the alternative fuels and safety concerns has also been reported in the respective sections and also in reviews of some LCAs (life cycle assessments). The report concludes with future recommendations to not only utilise the expertise available at JRC in developing testing standards for the new fuels, but also to assist in formulation of policies that will direct the present positive momentum in the shipping industry as it is doing for the road transport sector. iv 1 Introduction Maritime transport of goods is not only a relatively clean form of transportation per kilogram of material (Fig. 1), but also an efficient mode requiring 2-3 grams of fuel per ton*km, compared to road transport by truck which is about 15 grams of fuel per ton*km (McGill, Remley and Winther, 2013). Because of fuel efficiency and the need to improve fuel resource efficiency, marine transport is receiving increased attention and as a consequence is projected to grow at an average annual rate of 5.3% between 2010 and 2035 (Vyas, Patel and Bertram, 2013). However, emissions from the marine transport sector contribute significantly to air pollution globally (EEA, 2012), and in 2013 marine transport accounted for 2.7% of global CO2 emissions (EC 2015). These emissions are expected to increase by a factor of 2 to 3 by 2050 if no measures are implemented (IMO 2009). Assessment for years 2007 through to 2012 show that international shipping emissions still remains problematic and that these may lead to significant health concerns in exposed populations (IMO 2014). Shipping particulate matter (PM) emissions have already been linked with approximately 60,000 cardiopulmonary and lung cancer deaths annually worldwide (Corbett et al., 2007). Figure 1. CO2 emissions of different transport modes (Mofor, Nuttall and Newell, 2015) Within Europe, 40,600 km of inland waterways and intra-EU maritime transport are used with inland navigation accounting for 1.6 % of final energy consumption in the transport sector (EC 2013). Emissions from this sector contributes to 1-7% of ambient air PM10 levels, 1-14% of PM2.5, and at least 11% of PM1 (Viana et al., 2014). In some non- European harbours, contributions have been reported for example of <5% of PM2.5 in Los Angeles (Minguillón et al., 2008) and 4-6% of PM2.5 in Seattle (Kim and Hopke, 2008). Contributions to ambient NO2 levels range between 7-24%, with the highest values being recorded in the Netherlands
