Schilling Power Station was an oil-fired power station in the proximity of the nuclear power station at Stade . It went into operation in 1960, was extended in 1962 and 1964, and was shut down in the 1980s. Since it principally served Hamburg north for the electricity supply of Hamburg and fed its current into the transformer station, the first overhead line crossing of the Elbe was built at that time at Stade, the Elbe Crossing 1 . The buildings still exist today and are occasionally used for disaster control exercises.

Given HFO's elevated sulfur contamination (maximum of 5% by mass), the combustion reaction results in the formation of sulfur dioxide SO 2 . Since the middle of the 20th century, HFO has been used primarily by the shipping industry due to its low cost compared with all other fuel oils, being up to 30% less expensive, as well as
168-461: Is contaminated with several different compounds including aromatics , sulfur , and nitrogen , making emissions upon combustion more polluting compared to other fuel oils. HFO is predominantly used as a fuel source for marine vessel propulsion using marine diesel engines due to its relatively low cost compared to cleaner fuel sources such as distillates . The use and carriage of HFO on-board vessels presents several environmental concerns, namely
196-421: The radiative forcing of black carbon, combinations of ground and satellite observations suggest a global solar absorption of 0.9W·m , making it the second most important climate forcer after CO 2. Black carbon affects the climate system by: decreasing the snow/ice albedo through dark soot deposits and increasing snowmelt timing, reducing the planetary albedo through absorption of solar radiation reflected by
224-599: The Arctic as the greatest threat to the local marine environment. Being the remnant of the distillation and cracking processes, HFO is characterized by an elevated overall toxicity compared to all other fuels. Its viscosity prevents breakdown into the environment, a property exacerbated by the cold temperatures in the Arctic resulting in the formation of tar-lumps, and an increase in volume through emulsification. Its density, tendency to persist and emulsify can result in HFO polluting both
252-601: The Polar Code include safety and pollution prevention related to navigation in both Arctic and Antarctic polar waters. The carriage and use of HFO in the Arctic is discouraged by the Polar Code while being banned completely from the Antarctic under MARPOL Annex I regulation 43. The ban of HFO use and carriage in the Antarctic precedes the adoption of the Polar Code. At its 60th session (26 March 2010), The Marine Environmental Protection Committee (MEPC) adopted Resolution 189(60) which went into effect in 2011 and prohibits fuels of
280-480: The area. The two main environmental concerns for HFO in the Arctic are the risk of spill or accidental discharge and the emission of black carbon as a result of HFO consumption. Due to its very high viscosity and elevated density, HFO released into the environment is a greater threat to flora and fauna compared to distillate or other residual fuels. In 2009, the Arctic Council identified the spill of oil in
308-585: The ban is anticipated for 2021, with widespread implementation by 2023. The Clean Arctic Alliance was the first IMO delegate nonprofit organization to campaign against the use of HFO in Arctic waters. However, the phase-out and ban of HFO in the Arctic was formally proposed to MEPC by eight countries in 2018: Finland, Germany, Iceland, the Netherlands, New Zealand, Norway, Sweden and the United States. Although these member states continue to support

Prior to
504-461: The initiative, several countries have been vocal about their resistance to an HFO ban on such a short time scale. The Russian Federation has expressed concern for impacts to the maritime shipping industry and trade given the relatively low cost of HFO. Russia instead suggested the development and implementation of mitigation measures for the use and carriage of HFO in Arctic waters. Canada and Marshall Islands have presented similar arguments, highlighting
532-683: The international marine shipping sector reports 207.5 million tonnes total fuel oil sales with HFO accounting for 177.9 million tonnes. Marine vessels can use a variety of different fuels for the purpose of propulsion, which are divided into two broad categories: residual oils or distillates. In contrast to HFOs, distillates are the petroleum products created through refining crude oil and include diesel, kerosene, naphtha and gas. Residual oils are often combined to various degrees with distillates to achieve desired properties for operational and/or environmental performance. Table 1 lists commonly used categories of marine fuel oil and mixtures; all mixtures including

To appease concerns and resistance, at its 6th session in February 2019, the PPR sub-committee working group developed a "draft methodology for analyzing impacts" of HFO to be finalized at PPR's 7th session in 2020. The purpose of the methodology being to evaluate the ban according to its economic and social impacts on Arctic indigenous communities and other local communities, to measure anticipated benefits to local ecosystems, and potentially consider other factors that could be positively or negatively affected by
672-497: The remnants or residual of petroleum sources once the hydrocarbons of higher quality are extracted via processes such as thermal and catalytic cracking . Thus, HFO is also commonly referred to as residual fuel oil. The chemical composition of HFO is highly variable due to the fact that HFO is often mixed or blended with cleaner fuels; blending streams can include carbon numbers from C 20 to greater than C 50 . HFOs are blended to achieve certain viscosity and flow characteristics for
