Lignite (derived from Latin lignum meaning 'wood'), often referred to as brown coal , is a soft, brown, combustible sedimentary rock formed from naturally compressed peat . It has a carbon content around 25–35% and is considered the lowest rank of coal due to its relatively low heat content . When removed from the ground, it contains a very high amount of moisture , which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation .
89-506: The Hazelwood Power Station is a decommissioned brown coal -fuelled thermal power station located in the Latrobe Valley of Victoria, Australia . Built between 1964 and 1971, the 1,600-megawatt-capacity power station was made up of eight 200MW units, and supplied up to 25% of Victoria's base load electricity and more than 5% of Australia's total electricity demand. It was a 'subcritical' pulverized coal-fired boiler . The station
178-539: A "Quit Coal" banner outside the plant while 12 activists occupied the brown coal pit, with two locking themselves to coal dredging equipment. This action drew worldwide attention to Hazelwood's CO 2 emissions and their harmful impacts on the global climate. On 6 November 2008 a group of seven people protesting against Australia's inaction on climate change walked onto the site of the Hazelwood power station and temporarily stopped one conveyor belt which carries coal from
267-480: A 60% increase in power generation since 1996, Hazelwood averaged up to 16 million tonnes (16,000,000 long tons; 18,000,000 short tons) of carbon dioxide each year and, after Loy Yang A Power station, was the second highest emitter in the Latrobe Valley until 2015. Hazelwood had been the site of two carbon capture trials to lower its CO 2 emissions (see below). In late 2008, International Power stated
356-560: A fuel for poor people compared to higher value hard coals. In Germany, briquettes are still readily available to end consumers in home improvement stores and supermarkets. An environmentally beneficial use of lignite is in agriculture. Lignite may have value as an environmentally benign soil amendment , improving cation exchange and phosphorus availability in soils while reducing availability of heavy metals, and may be superior to commercial K humates. Lignite fly ash produced by combustion of lignite in power plants may also be valuable as

Police also deployed personnel in dingies in adjacent pondage lakes. A large number of activists also deployed video recording during the day. The rally began at 11am with speeches from Australian Greens Scott Ludlam, Dave Sweeney from
534-416: A net wet basis. Lignite has a high content of volatile matter which makes it easier to convert into gas and liquid petroleum products than higher-ranking coals. Its high moisture content and susceptibility to spontaneous combustion can cause problems in transportation and storage. Processes which remove water from brown coal reduce the risk of spontaneous combustion to the same level as black coal, increase
623-708: A realignment of Hazelwood's mining licence boundaries that were originally set in 1996. Hazelwood returned over 160 million tonnes of coal to the State Government as part of that agreement. The agreement required Hazelwood to reduce its estimated emissions by 34 million tonnes (33,000,000 long tons; 37,000,000 short tons) and capped its total greenhouse output at 445 million tonnes (438,000,000 long tons; 491,000,000 short tons) of carbon dioxide over its life, after which point it may have been made to cease operation. However, credits for investment in renewable energy and low emission technology were expected to allow
712-430: A result of increased temperatures and pressures underground. Lignite forms from peat that has not been subjected to deep burial and heating. It forms at temperatures below 100 °C (212 °F), primarily by biochemical degradation. This includes the process of humification, in which microorganisms extract hydrocarbons from peat and form humic acids, which decrease the rate of bacterial decay. In lignite, humification
801-640: A result, its carbon content on the as-received basis (i.e., containing both inherent moisture and mineral matter) is typically just 25-35 percent. The energy content of lignite ranges from 10 to 20 MJ/kg (9–17 million BTU per short ton ) on a moist, mineral-matter-free basis. The energy content of lignite consumed in the United States averages 15 MJ/kg (13 million BTU/ton), on the as-received basis. The energy content of lignite consumed in Victoria, Australia, averages 8.6 MJ/kg (8.2 million BTU/ton) on
890-413: A soil amendment and fertilizer. However, rigorous studies of the long-term benefits of lignite products in agriculture are lacking. Lignite may also be used for the cultivation and distribution of biological control microbes that suppress plant pests. The carbon increases the organic matter in the soil while the biological control microbes provide an alternative to chemical pesticides. Leonardite

Growing electricity demand saw a review carried out by the SECV in 1963, with commissioning of the generating units moved forward to 1969. Additional capacity was provided when in 1965 two additional generating units at Hazelwood were approved, to be commissioned in 1970 and 1971 respectively. Hazelwood relied on brown coal deposits from

Another worker, trained in asbestos identification, said for years Hazelwood management had ignored workers' concerns. International Power Hazelwood spokesperson Neil Lawson has responded, "It is well documented that there is still an amount of contained asbestos material which, if required,
1691-431: Is now of lower importance than its use to generate electricity. Lignite is often found in thick beds located near the surface, making it inexpensive to mine. However, because of its low energy density , tendency to crumble, and typically high moisture content, brown coal is inefficient to transport and is not traded extensively on the world market compared with higher coal grades. It is often burned in power stations near
1780-492: Is partial, coming to completion only when the coal reaches sub-bituminous rank. The most characteristic chemical change in the organic material during formation of lignite is the sharp reduction in the number of C=O and C-O-R functional groups. Lignite deposits are typically younger than higher-ranked coals, with the majority of them having formed during the Tertiary period. Lignite is often found in thick beds located near
1869-583: The Clean Energy Future Group together with Environment Victoria released the report "Toward Victoria's Clean Energy Future" , a plan to cut Victoria's Greenhouse gas emissions from electricity by 2010. It largely focused on cleaner alternatives to Hazelwood, and warned that continued support of coal-fired power development would lock the State into CO 2 emissions that would dwarf any current proposed measures for reducing emissions.

In July 2015, Hazelwood owners GDF Suez announced that the company would refuse to pay the 18 million dollar bill for fighting the fire presented by the Country Fire Authority. According to a statement released by the company, the firefighting effort should be provided to it at no further charge as it had already paid routine taxes and levies in previous years, although
2937-615: The Latrobe Valley as a clean energy hub. In June 2009, an anonymous letter purporting to come from the Earth Liberation Front was sent to the home of the CEO of the power station, Graeme York. The letter threatened to harm property, but did not threaten physical harm against any individuals or animals, despite being portrayed as such in commercial media due to the ELF activities overseas. ELF media spokesperson Jason Crawford defended
3026-676: The OECD nations in a 2005 report by WWF Australia. The WWF reported that the power station produced 1.58 tonnes (1.56 long tons; 1.74 short tons) of CO 2 per megawatt-hour of electricity generated in 2004 (official result was 1.55), which was a reduction of 6.6% from the 1996 levels of 1.66 Mt/TWh when the plant was privatised. This is still 50% more polluting than the average black coal power station in NSW or Queensland. Hazelwood emitted up to 15% of Victoria's annual greenhouse gas emissions and 3% of Australia's greenhouse gas emissions before closure. With

Our employees past and present, as well as contractors, local suppliers and businesses, and the broader Latrobe Valley community have all played their part in ensuring that Hazelwood has been a key player in the nation's electricity system over that time. Victoria should be very proud that Hazelwood has continued operating for more than 50 years, producing
4183-639: The entire Hazelwood plant would be closed at the end of March 2017 giving five months notice of the closure. The power station closed in March 2017. When the power station closed, wholesale prices in Victoria were up 85% on 2016, according to the Australian Energy Regulator , and for the first time in almost a decade, the state relied on energy from interstate to meet its needs. A 150 MW one-hour grid battery opened in June 2023. Development of

The largest lignite deposits in North America are the Gulf Coast lignites and the Fort Union lignite field. The Gulf Coast lignites are located in a band running from Texas to Alabama roughly parallel to the Gulf Coast. The Fort Union lignite field stretches from North Dakota to Saskatchewan . Both are important commercial sources of lignite. Lignite can be separated into two types: xyloid lignite or fossil wood , and compact lignite or perfect lignite. Although xyloid lignite may sometimes have

6230-746: The range of activated carbons currently used by industry. Jet is a form of lignite that has been used as a gemstone. The earliest jet artifacts date to 10,000 BCE and jet was used extensively in necklaces and other ornamentation in Britain from the Neolithic until the end of Roman Britain . Jet experienced a brief revival in Victorian Britain . Lignite begins as partially decayed plant material, or peat. Peat tends to accumulate in areas with high moisture, slow land subsidence , and no disturbance by rivers or oceans – under these conditions,
6319-449: The remainder of the business being renamed International Power. The Company was first listed on the London Stock Exchange on 2 October 2000. In August 2010 the company announced a tie-up with GDF Suez via a reverse takeover whereby GDF Suez transferred its Energy International Business Areas (outside Europe) and certain assets in the UK and Turkey to International Power in exchange for 70% of
6408-458: The role the power station has played in the Latrobe Valley. "While Friday will be the end of an era and a very sad day for everyone who has had an involvement with Hazelwood over the past 52 years, it should also be a very proud day," Keisser said. "The decision to close Hazelwood was extremely difficult and was made only after we investigated all options to keep the business open. While it was state-of-the-art when it opened in 1964, it has now reached
6497-505: The source, various toxic heavy metals , including naturally occurring radioactive materials , may be present in lignite and left over in the coal fly ash produced from its combustion, further increasing health risks. Lignite is brownish-black in color and has a carbon content of 60–70 percent on a dry ash-free basis. However, its inherent moisture content is sometimes as high as 75 percent and its ash content ranges from 6–19 percent, compared with 6–12 percent for bituminous coal . As
6586-464: The state of mines around the country, and the risks they posed to nearby communities. On 11 March 2014, Premier Dennis Napthine announced a judicial inquiry into the circumstances and impacts of the fire. The Hazelwood Mine Fire Inquiry Report was published in 2016 and stated that the community has experienced adverse health effects and may be affected for an indeterminate period into the future. The inquiry found that 11 premature deaths were attributed to
6675-499: The stock of the combined entity. The remaining 30% remained in the ownership of the existing International Power shareholders. The combination was completed on 3 February 2011 following approval by shareholders. In October 2010 MeyGen , a consortium of Morgan Stanley , Atlantis Resources Corporation and International Power, received an operational lease from the Crown Estate for a 400MW tidal power project for 25 years in
6764-422: The subsurface beds. Topsoil and subsoil must be properly removed and either used to reclaim previously mined-out areas or stored for future reclamation. Excavator and truck overburden removal prepares the area for dragline overburden removal to expose the lignite beds. These are broken up using specially equipped tractors ( coal ripping ) and then loaded into bottom dump trucks using front loaders . Once
6853-409: The surface. These are inexpensive to extract using various forms of surface mining , though this can result in serious environmental damage. Regulations in the United States and other countries require that land that is surface mined must be restored to its original productivity once mining is complete. Strip mining of lignite in the United States begins with drilling to establish the extent of
6942-401: The tenacity and the appearance of ordinary wood, it can be seen that the combustible woody tissue has experienced a great modification. It is reducible to a fine powder by trituration , and if submitted to the action of a weak solution of potash , it yields a considerable quantity of humic acid . Leonardite is an oxidized form of lignite, which also contains high levels of humic acid. Jet
7031-477: The vulnerable groups of people in Morwell South to temporarily relocate due to the danger of PM2.5 particles. Power lines and connectors at the Morwell substation were washed for ash buildup to reduce the risk of short circuiting. Tim Flannery questioned whether GDF Suez was taking sufficient action to keep the community informed and said the fire highlighted the need for better preparation and inquiry into
7120-449: The world's highest-emitting plant being Australia's Hazelwood Power Station until its closure in March 2017. The operation of traditional brown-coal plants, particularly in combination with strip mining , is politically contentious due to environmental concerns. The German Democratic Republic relied extensively on lignite to become energy self-sufficient , and eventually obtained 70% of its energy requirements from lignite. Lignite
7209-496: Was also an important chemical industry feedstock via Bergius process or Fischer-Tropsch synthesis in lieu of petroleum, which had to be imported for hard currency following a change in policy by the Soviet Union in the 1970s, which had previously delivered petroleum at below market rates. East German scientists even converted lignite into coke suitable for metallurgical uses ( high temperature lignite coke ) and much of
7298-428: Was earmarked for future coal supply. Environment Victoria , Greenpeace and Australian Conservation Foundation opposed the development approvals, while business groups such as Minerals Council of Australia, VECCI, Aust Industry Group and Institute of Public Affairs welcomed the government's decision. Hazelwood's coal supply would likely have run out around 2009 without the 2005 coal mine extension. This extension, and
7387-507: Was estimated to provide sufficient coal for the plant to operate to at least 2030 (prior to decommissioning plans). The EES also capped its expected total greenhouse output at 445 million tonnes of carbon dioxide over its life, after which Hazelwood may have been made to cease operation. Hazelwood was jointly owned by Engie with a 72% share and Mitsui & Co with a 28% share. In 2014, Hazelwood employed 495 staff directly and on average 300 contractors. On 3 November 2016, Engie announced that
7476-655: Was legislated in the Electricity Industry Amendment (Critical Infrastructure) Act 2009 (Vic). The legislation has been welcomed by the power industry but criticised by green groups for supposedly criminalising non-violent civil disobedience, and has been compared to the lockdown powers of the Major Events Act 2009, which has been reportedly used to intimidate and disperse peaceful protesters in NSW. On 11 August 2005 approximately 50 student environmentalists and Greenpeace volunteers unfurled
7565-584: Was listed as the least carbon efficient power station in the OECD in a 2005 report by WWF Australia, making it one of the most polluting power stations in the world. At 1.56 tonnes of CO 2 for each megawatt hour of electricity, it was 50% more polluting than the average black coal power station in New South Wales or Queensland. Hazelwood emitted 14% of Victoria's annual greenhouse gas emissions and 3% of Australia's greenhouse gas emissions. International Power plc purchased Hazelwood Power Station and
7654-412: Was lost. All seven were later charged by Victoria Police. A large mass civil disobedience rally, the largest of its kind at any Australian power station, was undertaken by a network of organisations under the banner Switch Off Hazelwood . On 13 September 2009, an estimated 500 people participated in near freezing conditions, with many camping nearby on the previous night on Hazelwood's own property beside
7743-531: Was near Morwell , 150 kilometres (93 mi) east of Melbourne . Prior to January 2011, IPR-GDF SUEZ Hazelwood had been known as International Power Hazelwood and Hazelwood Power before that. After privatisation the new owners engaged in capital investment, with A$ 800 million invested in Hazelwood since 1996, such as replacement of boilers, rotors, turbines and the completion of an A$ 85 million project to reduce dust emissions by 80%. If Hazelwood had not been sold to private interests, activist groups say
7832-424: Was on the agenda; and petitioning the mine owner to pay its firefighting bill to the Country Fire Authority. It afterwards entered into a campaign to improve coal mine rehabilitation efforts in Victoria and to ensure that mine rehabilitation bonds cover the actual costs of rehabilitation. in 2015, it started a petition signed by thousands of Victorians to call on the French government to phase out Hazelwood. In May 2016
7921-484: Was shut down last at 4.56pm. It was chosen to be last because Unit 1 was the first Hazelwood generating unit to come into operation on 30 November 1964. Decommissioning of mine and power station plant and equipment was expected to take 12 months. In a press release on the subject of the closure, Engie in Australia's Chief Executive, Alex Keisser, acknowledged the contributions of past and present Hazelwood employees, and
