Coal upgrading technology Coal upgrading technology Coal upgrading technology refers to a class of technologies developed to remove moisture and certain pollutants from low rank coals such as sub-Bituminous coal and lignite (brown coal) and raise their calorific values. Companies located in Australia, Germany and the United States are the principal drivers of the research, development and commercialisation of these technologies. Around 30 nations collectively operate more than 1,400 brown coal-fired power stations around the world. Brown coal power stations that cannot economically dewater brown coal are inefficient and cause of high levels of carbon emissions. High emitting power stations, notably the Hazelwood
A. B. Brown Generating Station A. B. Brown Generating Station The A. B. Brown Generating Station is a four-unit, 700 megawatt (MW) power plant, located on the northern bank of Ohio River, east of Mount Vernon, Indiana and southwest of Evansville, Indiana just west of the Posey-Vanderburgh County Line. Each of the two coal-fired units has a name-plate capacity of 265.2 MW. Bituminous coal is used as a primary fuel type, which can be substituted for natural gas. There are also two gas turbine units, 88.2 MW of nameplate capacity each. The facility is owned by Vectren (formerly Southern Indiana Gas and Electric Company). In
