US DOE CCS IGCC Projects – Membranes, Solvents, Sorbents, Novel Ideas
This post provides details of US DOE selected / funded projects for CCS of IGCC power plants. Data provided here are based on a June 2009 article from Carbon Capture Journal
The US DOE has selected nine projects that will develop pre-combustion carbon capture technologies for coal-based IGCC plants. The projects, totaling nearly $14.4 million, will be managed by the Office of Fossil Energy’s National Energy Technology Laboratory.
High-Temperature, High-Pressure Membranes
The focus of this research area is membrane-based separation devices.
* University of Minnesota, Minneapolis, Minn.—This project aims to develop defect-free, contaminant-resistant, hydrothermally stable molecular sieve membrane films with minimally tortuous path for diffusion of the preferred hydrogen molecules from the shifted synthesis gas mixtures
* Pall Corp., Cortland, N.Y.—Pall Corporation will leverage its proprietary combinatorial membrane fabrication technology to screen a large number of potential ternary palladium (Pd)-alloys for sulfur-tolerant, phase-stabilized hydrogen transport membrane candidates for separating hydrogen from shifted synthesis gas mixtures
* Arizona State University, Tempe, Ariz.—Researchers at Arizona State will integrate the water gas shift reaction with a CO2 selective membrane to separate CO2 from shifted synthesis gas.
High Efficiency Solvents
* SRI International, Menlo Park, Calif.—SRI will use aqueous NH4CO3 based solvents to capture high-pressure CO2 at lower solvent cost and with an efficient regeneration process.
Applications were sought for R&D leading to optimal performance of novel sorbents for adsorbing CO2 with fast adsorption-desorption, and regeneration kinetics, and a low energy requirement to regenerate the sorbent material.
* TDA Research, Inc., Wheat Ridge, Colo.—TDA will develop novel mesoporous carbon with Lewis base functionalized groups that remove CO2 via physical adsorption.
* URS Group, Austin, Texas—Using a molecular computational approach to formulate and then fabricate superior sorbent material, URS Group will combine modeling and experiments to tailor sorbents properties for optimum CO2 capture.
* Gas Technology Institute, Des Plaines, Ill.—GTI will couple an engineered plastic contactor with an appropriate solvent to potentially achieve 60% operating cost and 70% capital cost reduction.
* Membrane Technology and Research, Inc., Menlo Park, Calif.—Membrane Technology and Research will develop a novel polymer membrane(s) for the separation of hydrogen from shifted synthesis gas.
* New Jersey Institute of Technology, Newark, N.J.—Researchers propose a pressure swing absorption approach to capture CO2 using an ionic liquid incorporated in either a ceramic hollow tube or polytetrafluoroethylene (PTFE) fiber membrane.
