New IGCC plant will capture 90% of CO2 with Siemens technology

World Coal,

Siemens Energy has been awarded a front end engineering design (FEED) contract by Summit Texas Clean Energy LLC to provide coal gasification and power block technology for the Texas Clean Energy Project (TCEP). The new polygeneration IGCC project will use coal as its feedstock. With a gross capacity of 400 MWe, the plant will also produce urea for the US fertiliser market.

The plant will have a carbon capture rate of 90%, one of the highest of any IGCC plant in the world. The CO2 will be used for enhanced oil recovery in west Texas. Siemens will be working with Fluor Corp. and Linde during the project’s FEED.

The project received a US$ 350 million award under the US Department of Energy’s Clean Coal Power Initiative (CCPI) - Round 3 to demonstrate the commercial integration of large-scale IGCC with CO2 capture and geologic storage.

The Texas Clean Energy Project will be located in Penwell, near Odessa. Siemens will deliver the gasification island technology, which will include two SFG-500 gasifiers. The power block will be based on an SGT6-5000F gas turbine modified to operate on high H2 syngas, which will allow the plant to have a very high carbon capture rate of about 3 million t/year. The power block will also include a Siemens SST-900RH steam turbine, air-cooled generators and SPPA-T3000 controls.
