Mitsubishi Heavy Industries in Japan successfully tested the use of this coal with an ash content of less than 0.2% in gas turbines (SKM, 2009). This impurity level should not cause major problems in the gas turbine. Initial estimates suggest that the fuel cost in Australia would be rather high, ASD 0.05 to ASD 0.08 per kWh, compared to ASD 0.02 per kWh for regular hard coal. Cost may come down as the technology develops.
