Effect of CO2 Injection on Geological Formations Studied

13.07.2011
Coal and Energy Center at Virginia Tech selected for study on injection of CO2 into storage reservoirs

In a test project, researchers plan to inject some 20,000 tons of carbon dioxide (CO2) into a coalbed methane field in southwest Virginia, at a site that is not suitable for underground mining purposes.

A cadre of government and private companies, led by the Virginia Center for Coal and Energy Research located at Virginia Tech, will be involved in the injection and subsequent monitoring. Some $11,500,000 in funding for this four-year project is coming from the U.S. Department of Energy (DOE), and is part of a portfolio of projects aimed at achieving a better understanding of the effect of CO2 on geologic formations.

“The proposed research will test the ability to inject CO2 into coal seams that cannot be mined, as well as the potential to enhance the coalbed methane recovery,” said Michael Karmis, the director of the Virginia Center for Coal and Energy Research and the Stonie Barker Chaired Professor of Mining and Minerals Engineering at Virginia Tech.

The project is based on a number of previously successful studies that have identified promising methods for storing CO2 in stacked underground reservoirs, and the ability to sequester the CO2, identified as a contributor to global warming, in the coal seams.

Research is ongoing as to which coal seams are good disposal sites and the conditions under which the impounded CO2 would remain stable.

For example, previous studies have indicated geologic formations in Central Appalachia are promising for storage and carbon sequestration. Results from these studies are the basis for the proposed work by Karmis and his colleagues. “However, limited experience with injection into coal, tight sandstone, and organic-rich shales in Central Appalachia makes commercial potential uncertain at this time,” Karmis said.

The grant to Karmis and his team is part of a larger effort recently announced by the DOE. On July 6, the federal agency released its intent to expand its efforts in insuring long-term geologic carbon dioxide storage is safe and environmentally secure with more than $45 million being devoted to these efforts.

The other two new DOE projects will allow Blackhorse Energy LLC of Houston, Texas and the University of Kansas Center for Research to perform similar studies.

In Virginia, Karmis will document the efforts and record the work into a best practices manual for carbon dioxide capture and storage activities. The manual is intended to help reduce storage risk by documenting the uncertainties related to these activities. Also, project data will be incorporated in the National Carbon Sequestration Database and Geographical Information System, an interactive online tool that integrates a wealth of information on worldwide efforts to deploy carbon capture and storage technology.

Carbon capture and storage is the process of capturing greenhouse gases from large stationary sources, such as power plants, and storing them in ways that prevent their release to the atmosphere, and is a key element in national efforts to mitigate climate change.

The Office of Fossil Energy’s National Energy Technology Laboratory (NETL) will manage the work.

Working with Karmis and his center will be: Marshall Miller & Associates; the Virginia Department of Mines, Minerals, and Energy; Southern States Energy Board; Gerald R. Hill Ph.D., Inc.; Geological Survey of Alabama; Sandia Technologies; and Det Norske Veritas. This research team has experience in a number of geologic storage characterization studies and carbon sequestration injection pilot studies under the Regional Carbon Sequestration Partnerships established by the NETL/ DOE.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
