Carbon Capture Boom: 100 CO2 Capture Projects, $56 Billion in a Decade

Posted by on Monday, 1 March, 2010

No fewer than 100 large-scale carbon capture and storage projects within about a decade, at a cost of some $56 billion — that’s what International Energy Agency chief Nobuo Tanaka said the world needs in order to help address climate change, according to Reuters.

At the Carbon Sequestration Leadership Forum, a conference of energy ministers taking place this week in London, Tanaka called for 850 CCS projects by 2030 and 3,400 by 2050, with a total investment of more than $700 billion over the next three decades. Those are huge numbers for an experimental technology that has yet to be proven at industrial scale.

The next decade represents a “key ‘make or break’ period” for carbon capture and storage technology, according to a 52-page CCS “Technology Roadmap” out today from the International Energy Agency, and it could open significant opportunities for startups. While large established power companies will likely dominate industrial storage projects, startups with novel chemical conversion technologies like GreatPoint Energy, and startups that recycle the carbon, like algae fuel firms like Solazyme, will likely benefit from the intergovernmental agency’s call to arms.

DOE CO2 Sequestration R&D Program – Breakthrough Ideas for Capturing, Storing CO2 Explored

Posted by on Friday, 12 February, 2010

DOE’s Carbon Sequestration R&D Program expands with addition of three university-sponsored projects

The three projects were selected in a broad competition run by the Energy Department’s National Energy Technology Laboratory. They were submitted by:

* University of Texas at Austin, Austin, TX. Researchers in the University’s Department of Chemical Engineering will develop an alternative solvent that captures more carbon dioxide while using 25 to 50 percent less energy than conventional, state-of-the-art MEA (monoethanol amine) scrubbing, another CO2-removal method. Using less energy allows coal plants to produce more electricity while capturing and storing CO2. The university will develop and validate a process model to optimize solvent rate, stripper pressure and other parameters. Because gas/liquid contact and CO2 mass transfer would be enhanced, capital costs may be reduced.

* University of Massachusetts, Lowell, MA, which proposes to study in a laboratory a deep-ocean CO2-sequestration method that blends liquid CO2, water and finely ground limestone into an emulsion that could be pumped into the ocean for long-term storage. Because this emulsion would weigh more than seawater, it would sink to the deep ocean. This would make it possible to CO2 at shallower depths than current directed-injection techniques. Soluble calcium bicarbonate, food for aquatic organisms, would be formed and stored in the ocean indefinitely.

* University of Kentucky Research Foundation, Lexington, KY. The University proposes to displace natural gas from black Devonian shales and use these organic-rich rocks to store CO2. Studies have shown that CO2 is preferentially adsorbed by gaseous coals in deep, unminable coal seams in very much the same manner that gas is naturally stored in these coals. In fact, CO2 displaces methane molecules two to one. The study will determine whether a similar phenomena takes place in Devonian black shales, which serve as both a source and a trap for natural gas.

US DOE CCS IGCC Projects – Membranes, Solvents, Sorbents, Novel Ideas

Posted by on Sunday, 31 January, 2010

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.

Solid Sorbents

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.

Novel Concepts

* 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.
