Project Description

The Texas Clean Energy Project (TCEP) is an integrated gasification combined cycle (IGCC) poly-generation facility with fully integrated  O2 capture that will be located in Penwell, Ector County, Texas. The TCEP will nominally generate 400 megawatts of electricity (MWe) gross using sub-bituminous coal and send about 200 MWe to the utility grid under agreement with CPS Energy of San Antonio. The Siemens power block will consist of an SGT6-5000F hydrogen (H2)-capable combustion turbine, a triple-pressure heat recovery steam generator (HRSG), and an SST-900RH reheat steam turbine. The project will use two Siemens SFG-500 entrained-flow, oxygen-blown gasifiers and two-stage water-gas shift to produce high-H2 synthesis gas (syngas). A Lindé Rectisol® acid gas removal (AGR) system will be used to achieve the intended 90 percent carbon capture efficiency for the entire syngas stream. The AGR system also captures sulfur-containing gases for on-site conversion to sulfuric acid product.

Up to about 2.6 million metric tonnes of CO2 per year will be captured. Under off-take agreements, about 76 percent of the CO2 will be compressed on-site and delivered via existing regional pipelines to depleted West Texas Permian Basin oil fields—the world’s largest market for CO2-flood enhanced oil recovery (EOR)—for geologic storage with concomitant EOR. The remaining CO2 will be used for on-site production of urea fertilizer under an off-take agreement with CHS Inc.
