Anglo Coal Australia is investigating the use of microwaves to dry coal and capture the evaporated water for re-use. Initial studies confirm that microwave drying is highly efficient and recovers more than 80% of the water.

Dry coal burns more efficiently, reducing the amount of coal required to produce the same heat. This cuts carbon dioxide emissions in power generation and steel production. Wet coal is also heavy, making it more costly (and more polluting) to transport.
