The basic idea of sequestration of CO2 from coal burning is flawed because each ton of coal burned produces about 3.7 tons of CO2!
In 2007 alone China added 91 GigaWatts of coal power plants. Over the next 20 years, those plants will emit about 15 billion tons of CO2. Where and how do you hide 15 billion tons of CO2?
Actually coal is sequestered carbon. Digging it up, processing, transporting, burning and then trying to re-sequester it along with a lot of Oxygen molecules from the air is just crazy.
Since the whole object is to boil water to run turbines, doesn´t it make more sense to use the free heat of geothermal energy in the earth to boil the water? If the money wasted on Futuregen had been spent instead on geothermal research we would already have a plentiful source of clean baseload power without ruining the planet. Why waste research money on ideas that can never work while zeroing funding for a promising solution like EGS geothermal?
