Clean coal: Firm claims world's first commercially viable, zero-carbon power plant is 'game changer'

A revolutionary technique to capture carbon emissions from coal-fired power stations has been shown to work on a commercially viable basis for the first time, the company behind it has claimed.  If true, the breakthrough could allow coal to continue to be burned on a large scale around the world without producing the greenhouse gases that cause climate change. A 10-megawatt power station in Chennai, India, is currently using CCSL’s system to generate electricity on a commercial basis while capturing some 97 per cent of its carbon emissions. CCSL says it developed a new solvent that makes the carbon capture process up to 66 per cent cheaper than traditional methods, costing $30 per tonne of carbon compared to $60 to $90.
