Hi Allen, I think CCS is a make work project to justify continuing to support coal mining and coal-fired power generation. Your comments very much point out the long-term lunacy of CCS in association with coal. If we are to develop CCS to harvest CO2 from the atmosphere then I would see some merit in it. But the only way the CCS developed here works is having CO2 available in large quantity. We need a CCS that works like trees. Hey! Wait a minute, we have trees. Why not plant more?]]> In reply to Allen Gage.

Any electricity in excess of the CCS process requirements would go into the power grid. The CO2 is then used to produce more oil from declining pressure-drive petroleum reservoirs, which will increase oil supplies and hold down prices, thus encouraging more global oil consumption by “sequestering” CO2 obtained by burning extra coal. Obviously some of the extra oil production from extra coal combustion will be burned in the ICE trucks that haul the cryogenic CO2 from the coal burning plant to the oil fields. History has shown that a 3% supply glut can produce as much as a 30% decline in petroleum market price.
Perhaps, if the CCS scheme can be made to work at all, the net effect would be greater coal combustion, higher electric rates, and more petroleum combustion. More likely, the scheme could only be implemented through drastic government mandates, and the combustion of coal in the first world would be discontinued and replaced with NG. Coal prices would fall and domestic producers would export to the third world, where the coal would be burned with minimal emission standards. Wouldn’t just one day’s worth of all the world’s coal plant’s CO2 emissions satisfy the entire global LCO2 demand for the next year? Suppose only 1% of the coal-fired power plants are capturing and liquefying their CO2, wouldn’t the CO2 supply immediately glut and market prices collapse? What is not to like? This seems a technology that will go only so far as technically incompetent and ethically corrupt governments are prepared to pay for it.
