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.

Project Benefits

A need exists to further develop carbon management technologies that capture and store, or beneficially reuse, carbon dioxide (CO2) that would otherwise be emitted into the atmosphere from coal-based electric power generating facilities. Carbon capture and storage (CCS) technologies offer the potential to significantly reduce CO2 emissions and mitigate the anthropogenic contribution to global climate change, while substantially reducing or minimizing the economic impacts of the solution.

Under Round 3 of the Clean Coal Power Initiative (CCPI), the U.S. Department of Energy (DOE) is providing up to $450 million in co-funded financial assistance to industry, including funding under the American Recovery and Reinvestment Act (ARRA) of 2009, to demonstrate the commercial viability of advanced technologies that will capture CO2 emissions and geologically store those emissions, or beneficially reuse them. Once demonstrated, the technologies can be readily considered in the commercial marketplace by the electric power industry.

The TCEP is a capstone demonstration representing decades of DOE-sponsored technology research and development into coal gasification; environmental controls for the oxides of nitrogen and sulfur, particulate matter, and mercury; hydrogen-capable combustion gas turbines; and CCS. The facility will be among the cleanest commercial, solid-fuel power facilities in the world and will significantly surpass the emissions reduction targets for 2020 established under the Energy Policy Act of 2005. The facility’s emissions will be far below any limits previously permitted in Texas for a fossil-fuel plant. Its CO2 emissions (on a lb. per MWhr basis) will be only 20–25 percent that of a comparably-sized natural gas combined cycle (NGCC) power plant without CO2 capture. Other specific project benefits include:

Goals and Objectives

The overarching objective is to advance CCS technologies from the demonstration stage to commercial practice. The goals of the TCEP are to design, build, and operate a greenfield, commercial-scale, fully-integrated, advanced IGCC electric power and chemicals production facility that demonstrates high CO2 removal from the pre-combustion syngas stream, compression and transport of pipeline-quality CO2, and the disposition through monitoring, verification, and accounting (MVA) of CO2 stored in deep geologic formations with concomitant EOR.
