Summit Power Group's Texas Clean Energy Project (TCEP) at Penwell was to be a 400 MWe IGCC power plant burning coal with CCS, capturing 90% of CO 2 and 90% of NO x precombustion. It had 811 million funding from the DOE Clean Coal Power Initiative towards its 4 billion cost. It was due to operate from 2019, but in 2016 DOE withdrew funding.

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.

Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

This raises the possibility that power plant developers will continue to follow the pattern of the 1990s and rely heavily on natural gas plants to meet the need for new generating capacity.! With current technology, coalfired power plants using carbon capture equipment are an expensive source of electricity in a carbon control case.

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.

Like any thermal power station, we generate electricity from steam. Our entire process can be simplified into four main steps: Fuel is burned to create heat. By using finely pulverized coal, efficient combustion is assured and high temperatures are achieved. The heat is applied to demineralized water inside the boiler, turning it into steam.

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.
