From the Kemper Project website:
State-of-the-Art Technology
The Kemper County energy facility is a 21st-century integrated gasification combined cycle (IGCC) design called TRIG. IGCC converts lignite coal to synthesis gas. The lignite is sent through a device called a gasifier where it undergoes a chemical reaction creating a synthesis gas. The gas is then used to generate power by firing it in a gas turbine.
TRIG was developed over the last two decades at the Power Systems Development Facility (PSDF) in Wilsonville, Ala. - a research facility for the department of energy and Southern Company.
A unique feature of TRIG is the high-efficiency design that sends lignite not converted to gas in the initial process back for a second round of gasification. This allows a high rate of lignite-to-gas conversion to take place at a lower temperature - and thus lower cost - than what's possible with other available gasification technologies.
TRIG produces gas that can be used to generate electricity while making it easier to remove emissions, such as carbon dioxide, that otherwise would end up in the atmosphere.
Clean coal power - I wonder how long it will take for the green marxists to backpedal on their anti-coal platform. The way they were demonizing it, you think that there was something actually bad about it. All that wonderful cheap fuel to recharge their Teslas. Plus, it is baseload - it doesn't go away when the wind stops blowing (or blows too fast).
Infogalactic has more on IGCC. I would prefer LFTR - proven nuclear technology and lots of other nations are building them. Cheap to build and chep to run. The spent fuel needs to be sequestered for about 300 years max.
