Will We Someday be Pumping CO2 into Every Hole, Dry Well and Crevice We Can Find?

Here is something worth watching for people who are are still undecided on whether it is feasible and practical to store carbon dioxide produced from the oxidation of coal ( or any other source for that matter) underground. In order to be effective in the battle against climate change ofcourse the CO2 must stay in its containment for ever which is a very long time. The prospect that this technology may someday be feasible seems to be  giving coal fired electrical generation a slightly greener image than I think it deserves.

 Duke Energy has filed testimony with the Indiana Utility Regulatory Commission describing a proposed carbon dioxide storage project in southwest Indiana. The company is proposing to study permanent underground storage of a portion of the carbon dioxide emissions from its Edwardsport coal gasification power plant under construction. Carbon dioxide is considered a greenhouse gas and is linked with global warming.

Earlier this year Duke Energy received permission to study capturing a portion of the plant’s carbon emissions. The U.S. House of Representatives recently passed a comprehensive measure to control carbon emissions and the U.S. Senate is expected to take up the issue following the congressional break.

Jim Stanley the President of Duke Energy Indiana had this to say;

Indiana gets more than 90 percent of its electric power from coal, and our country has hundreds of years of reserves. The real-world testing of carbon capture and storage is critical to the continued use of an abundant and relatively inexpensive domestic energy source. This is a step toward the important goal of exploring the permanent underground storage of carbon dioxide emissions.

Duke Energy is proposing to invest approximately $121 million for a detailed characterization of storage sites, including the drilling of multiple wells. The project involves exploring sequestration in deep saline aquifers as well as use in enhanced oil recovery and storage in depleted oil or gas fields. In enhanced oil recovery, carbon dioxide is used to help stimulate oil and gas production underground.

The three-year site characterization would result in about a 1 percent average customer rate increase phased in between 2010 and 2013. If the study is successful, Duke Energy will ask state utility regulators for permission to implement carbon capture and storage.

In January, Duke Energy applied for a Department of Energy Clean Coal Power Initiative Round 3 grant, which could potentially offset up to 50 percent of the costs of carbon capture and storage for the Edwardsport project. The U.S. government increased funding of this DOE initiative through federal stimulus funding and the company plans to refile its application in August. Any funds received would be used to reduce customer rate impacts of the project.

 Stanley added;

This will be one of the nation’s first demonstrations of carbon capture and storage at a power plant . Edwardsport will be one of the cleanest coal-fired plants in the world when it’s completed. It uses advanced technology to turn coal into a cleaner-burning gas, and strips out pollutants before the gas is burned. Our state will be a leader in showing how coal can be used cleanly and effectively to produce electricity.
