The chart below is from the Minerals Council of Australia submission on the government's energy policy issues paper. It conceals two significant facts: 1. Existing natural gas power stations achieve 60 per cent thermal efficiency and produce just 330 g of CO2 per kWh. 2. The coal industry has built and tested two coal-to-gas power stations in the US that are able now to capture CO2. These power stations can use natural gas or coal as fuel. They reduce the amount of coal needed to produce electricity. It seems the coal industry wishes to ensure that technology to reduce demand for coal is not used.
