Exhaust emissions from marine vessels are coming under strict regulation from authorities tasked to clean up global air quality and minimise the adverse impact of emissions on human health and global warming.
Research in the USA by the National Oceanic and Atmospheric Administration has concluded that pollution from the worlds 90,000 cargo ships leads to 60,000 deaths a year around the world, and in the USA alone costs up to $330bn in health care due to lung and heart disease. The Environmental Protection Agency (EPA) estimates that the Emission Control Area (SECA) set up along the west cost of the USA will save more than 8,000 lives a year by cutting sulphur in marine fuel by 98%, particulate matter by 85% and nitrous oxide emission by 80%.
There has been heavy investment from industry to deliver cleaner outputs from power stations and to reduce the sulphur content of automotive diesel fuels from over 500ppm to less than15ppm. Cars driving 15,000km per year emit approximately 1000g of SOx. Marine heavy fuel oil contains around 45,000ppm of sulphur and the world’s biggest ships generate around 5,200 tons of SOx in one year.
