An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.

Most and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.

Steps in Electricity Generation from Lignite. Lignite is delivered to the power plant. Depending on the power plant, the lignite is crushed to approximately ¼ inch size coal or pulverized into a fine powder so it will burn more quickly. The crushed or pulverized coal is then blown into a boiler combustion chamber, or furnace.
