Methodology for Greenhouse Flexible High-pressure Dual-fuel 50 CFD 56 Injector Gas Emissions Reduction for Future Fuels
The corona pandemic has given some, including the shipping industry for example, an involuntary pause. World trade levels fell in the spring, more container ships than normal were stuck in port, oil tankers suddenly became floating storage facilities for crude oil that no one wanted to buy and the cruise industry was brought to an almost complete standstill. This sudden disruption to trade throughout the world is bad for the economy but good for the climate. But the future for the shipping industry in particular looks rather different, according to the fourth Greenhouse Gas Study published by the International Maritime Organization (IMO). The IMO commissioned ten universities, consultancies and research institutions to determine the greenhouse gas emissions from the global shipping industry over the past decade and in the period up to 2050. First the good news: from 2012 to 2018 the efficiency of ship engines increased by 11 %. However, over the same period the 40-% increase in global maritime trade led to an almost 10-% rise in greenhouse gas emissions from ships. The IMO study also forecasts an increase in maritime trade volumes over the next few decades. Despite the growing efficiency of ship engines, depending on the scenario, the expectation is that greenhouse gas emissions will rise by 50 % by 2050 when compared with the reference year 2018. This means that the industry will dramatically fail to meet its target of a 50 % reduction in greenhouse gas emissions from shipping by 2050 which was set by the Marine Environment Protection Committee of the IMO two years ago.

This example indicates the challenges facing large-bore engines over the decades to come: efficiency, reductions in pollution and the struggle for every bit of improved environmental friendliness. On the following pages you will find four articles that offer possible solutions. These include using simulation to optimize the combustion process (AVL), new injection methods (L’Orange), oil mist separation in blow-by gases (UT99) and new engine concepts for more environmentally friendly fuels (MTU). As the Esso adverts in Germany said around 40 years ago: “There’s lots to do. Let’s get started!” Hartmut Hammer
