China is now the proud owner of the world’s first all-electric cargo ship and has already put the vehicle to use. As reported by China Daily, the 2,000-metric-ton ship was launched in the city of Guangzhou last month and runs in the inland section of the Pearl River.
Constructed by Guangzhou Shipyard International Company Ltd, it can travel 80 kilometers (approximately 50 miles) after being charged for 2 hours. As noted by Clean Technica, 2 hours is roughly the amount of time it would take to unload the ship’s cargo while docked
“As the ship is fully electric powered, it poses no threats to the environment,” said Huang Jialin,

Crucially, shipping exploits a ready supply of the world's cheapest, most polluting "bunker" fuel. Marine heavy fuel oil, which is burned by all large ships, is the residue of the world's oil refineries and is so thick that when cold it can be walked on. It is 60% cheaper than cleaner oils and, according to the report, demand for it is soaring.
"Bunker fuel is just waste oil, basically what is left over after all the cleaner fuels have been extracted from crude oil. It's tar, the same as asphalt. It's the cheapest and dirtiest fuel in the world," said Christian Eyde Moller, chief executive officer of the Rotterdam-based DK Group, a leading shipping technology company.
Air pollution from cruise ships is generated by diesel engines that burn high sulfur content fuel oil, also known as bunker oil, producing sulfur dioxide, nitrogen oxide and particulate, in addition to carbon monoxide, carbon dioxide, and hydrocarbons. Diesel exhaust has been classified by EPA as a likely human carcinogen. EPA recognizes that these emissions from marine diesel engines contribute to ozone and carbon monoxide non-attainment (i.e., failure to meet air quality standards), as well as adverse health effects associated with ambient concentrations of particulate matter and visibility, haze, acid deposition, and eutrophication and nitrification of water. EPA estimates that large marine diesel engines accounted for about 1.6 percent of mobile source nitrogen oxide emissions and 2.8 percent of mobile source particulate emissions in the United States in 2000. Contributions of marine diesel engines can be higher on a port-specific basis. Ultra-low sulfur diesel (U'___') is a standard for defining diesel fuel with substantially lowered sulfur contents. As of 2006, almost all of the petroleum-based diesel fuel available in Europe and North America is of a U'___' type.
In 2016 the IMO has made new sulfur regulations which must be implemented by larger ships by 2020.
Of total global air emissions, shipping accounts for 18 to 30 percent of the nitrogen oxide and 9 percent of the sulphur oxides.  Sulfur in the air creates acid rain which damages crops and buildings. When inhaled, sulfur is known to cause respiratory problems and even increases the risk of a heart attack. According to Irene Blooming, a spokeswoman for the European environmental coalition Seas at Risk, the fuel used in oil tankers and container ships is high in sulfur and cheaper to buy compared to the fuel used for domestic land use. "A ship lets out around 50 times more sulfur than a lorry per metric tonne of cargo carried." Cities in the U.S. like Long Beach, Los Angeles, Houston, Galveston, and Pittsburgh see some of the heaviest shipping traffic in the nation and have left local officials desperately trying to clean up the air. Increasing trade between the U.S. and China is helping to increase the number of vessels navigating the Pacific and exacerbating many of the environmental problems. To maintain the level of growth China is experiencing, large amounts of grain are being shipped to China by the boat load. The number of voyages are expected to continue increasing.

It is cool and a step in the right direction, but it is made to move COAL. Of all things. lol
The breakdown of NOx gases gives rise to increased OH abundance and so helps to reduce the lifetimes of greenhouse gases like methane. Sources of NOx include fossil fuel burning, biomass burning and emission from soils.
