When I first heard about the project I questioned the wisdom of using the lignite found in our area of Mississippi (about 15 miles from the plant location). I’ve never heard of anyone trying to burn this lignite. Even in a forest fire the “outcroppings” of lignite don’t burn. The byproducts of the process are said to be sulfuric acid and CO2. They say they already have customers that will buy both byproducts. The CO2 will go into a pipeline for transport about 40 miles South to the oil fields.

It also will produce 65 percent less carbon dioxide emissions than the current pulverized coal plants.” And I note that they are in fact using a coal gasification process and calculating their CO2 emissions on a kW generated basis. It is a far better system efficiency than a single step process but it certainly comes at a cost. There was initial talk about putting one into Ulaanbaatar as they 520 MW plant is getting close to capacity. It is pretty expensive. The inherent emissions of mercury etc are already removable. I note they are talking at Southern of carbon capture. Perhaps someone will pay them to do that too. Regards Crispin ++++++= Crispin, This plant is a scaled up version of an existing process.

It has been licensed to China. It was developed for a Mississippi-based coal deposit. The Boss man (CNBC interview) did not define ‘cleaner’. My suspicion is that it is a fuel composition-related achievement. The H2 content of the fuel must be high. It also must be a statement conditioned on the combustion devices being defined in order to make the comparison. I am happy to hear that they have done at a large scale what we have done on a micro scale. I am willing to bet it is a combined cycle gasification mode power plant. The increased efficiency reduces the emissions per kW output.
