Carbon Capture Costs: FEED & pre-FEED Cost Reports

The University of Texas at Austin, with AECOM Technical Services and Trimeric Corporation, is conducting a FEED study for the Piperazine Advanced Stripper (PZAS) CO₂ capture process at Golden Spread Electric Cooperative’s Mustang Station in Denver City, Texas. Designed for two GE gas turbines with HRSGs and a steam turbine totaling 464 MWe, the PZAS process uses 30 wt% piperazine for higher efficiency, solvent stability, smaller absorber size, and cost savings compared to conventional amine systems. The project will deliver a 30–60% complete design package and a capital cost estimate with ±15% accuracy.

Southern Company Services, with Linde Gas North America, is conducting a FEED study for a commercial-scale CO₂ capture system using Linde-BASF’s advanced aqueous amine technology at an NGCC plant of at least 375 MWe. The project will evaluate Alabama Power’s Plant Barry and Mississippi Power’s Plant Daniel to select the optimal host site, define project requirements, optimize process design, and deliver engineering packages along with a cost and schedule estimate within 15% accuracy. The study will build on prior feasibility work and site-specific testing.
