Double power from Coal with less Emissions

Why doesn’t the government push to get this installed in all coal burning plants ASAP?
“A UNIVERSITY of Queensland scientist said yesterday he had successfully tested technology that delivers twice the power from coal while minimising greenhouse gas emissions. Professor John Zhu, of the school of chemical engineering, created a series of direct carbon fuel cells (DCFC) in which burning coal generates highly energy-efficient electricity.
”The very high-energy efficiency of the new technology will effectively halve the amount of coal required to create electricity,” he said. ”When applied, it will provide industry with very significant cost and energy savings, which could then be passed on to the consumer.
In addition to saving cost and energy, the direct carbon fuel cells will also provide clean power.” He said he expected the fuel cells would enable the byproduct of coal-fired power – the harmful greenhouse gas carbon dioxide – to be trapped and stored easily and safely.
”One of the major challenges for coal-fired power is reducing its impact on the environment by developing ways to separate carbon dioxide from other gases produced in the power generation process, and ensuring it is not released into the atmosphere,” he said. ”The DCFC produces pure carbon dioxide as a byproduct, making it much easier to manage.” – Source
