The upfront capital cost of low emissions process heat equipment, while substantial, is often competitive with or cheaper than fossil fuel fired assets. However, the cost of refurbishing and extending the life of an existing fossil fuel asset is often cheaper and easier than replacing it with a low emission alternative.

Brown coal. Raw brown coal, containing up to 70 per cent moisture, has long been regarded as inferior to black coal as a fuel. Nonetheless, brown coal was discovered in Victoria in the 1860s and, in the absence of a major black coal resource, was mined near Morwell from 1887. The Great Morwell Coal Mining Company made the first Victorian ...
