Victorian brown coals represent one of the purest and most extensive concentrations of organic matter anywhere in the world with ash yields generally less than 2%. These coals typically contain 69.6% carbon, 5.0% hydrogen, 24.6% oxygen, 0.5% nitrogen, and 0.3% sulfur on a dry mineral and nonmineral-inorganic free basis.

Brown coal basics. Victoria's lignite is typically low in ash, sulphur, heavy metals and nitrogen. However, its high moisture content - which ranges from 48-70 per cent - reduces its effective energy content (average 8.6 MJ/kg on a net wet basis or 26.6 MJ/kg on a gross dry basis).

Victorian brown coal is a cost effective fuel for power generation. It is very cheap to mine and low in sulphur and ash yield but the high moisture content and hence low calorific value result in high CO 2 emission intensity relative to bituminous coal. This high moisture has ensured that power stations are located adjacent to their mines to minimise handling, …

We investigated the phase compositions of four categories of brown coal ashes and synthetic slags after processing at 900–1100 °C and 1200–1600 °C, respectively, under reducing conditions similar to those used in coal gasification. We also determined the ash fusion temperature (AFT) of ashes and slag viscosity, and discuss …

Australia has vast brown coal resources, although these have a much lower energy content than black coal. Brown coal TDR are estimated to be 3,247,899 PJ (331,423 Mt) and are located mainly in Victoria's Gippsland Basin. Australia's brown coal TDR showed a modest increase of less than 1 per cent between 2019 and 2020, and will support over ...

Under the $500m Hydrogen Energy Supply Chain (HESC) pilot project, hydrogen will be made in Victoria's LaTrobe valley from brown coal and transported aboard a purpose-built ship to Japan, where ...

The Australian government has given $57m to the project so far. ... hydrogen from brown coal would release 40kg of CO2 for each unit of energy (a gigajoule).

The four types of coal include peat, lignite (or brown coal), bituminous (or hard coal), and anthracite. The coal is classified in terms of the change it has undergone from peat to …

Bringing coal to light. The Latrobe valley is rich in one of Victoria's most important resources: lignite, or brown coal as it's commonly known. This coal is responsible for 85% of the electricity in Victoria, and also supplies electricity to Tasmania and New South Wales. The Yallourn mine is the oldest in Victoria, and Australia's second-largest open cut mine.
