Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
Limestone III | Beyond Coal - Sierra Club National There is not much to report on the proposed Limestone III coal plant. ... and make a final decision on the air permit for the Limestone III coal-fired power plant.
For older coal-fired power plants this included installing scrubber systems in the smokestacks to filter sulfur from the exhaust. "In 1985, Plains Electric built a power plant in nearby Prewitt, New Mexico and the project manager needed a source for limestone that would pass the qualifications required for the power plant emissions," he says.
Work has proceeded on three processes: (1) limestone injection (dry process), (2) use of limestone in a wet-scrubbing process, and (3) ammonia scrubbing. The limestone injection study has been completed and a report issued: "Sulfur Oxide Removal from Power Plant Stack Gas-Sorption by limestone or lime (Dry Process)" (1968).
In June 2006, NRG Energy proposed plans to build a new 744 megawatt pulverized coal power plant at its existing 1,614 MW Limestone Station, located in Jewett about 120 miles northwest of Houston. The new unit, named Limestone III, would cost $1.2 billion and enter service in 2012, if allowed to proceed.

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
