PSC issues final report on the potential for carbon sequestration

From a news release issued by the Public Service Commission of Wisconsin:

MADISON – The Public Service Commission of Wisconsin (PSC) in partnership with the Wisconsin Department of Natural Resources (DNR) today issued a final report on the potential for geologic sequestration of carbon dioxide produced by coal-fired power plants serving Wisconsin electricity consumers.

Based on recommendations by the Governor's Task Force on Global Warming, the PSC and the DNR formed a Study Group to look into the potential for geologic carbon sequestration to help satisfy Wisconsin’s need for cleaner sources of electricity. Geologic sequestration involves a process of capturing carbon dioxide produced by power plants that otherwise would be released into the atmosphere and securely storing, or sequestering, the carbon dioxide (CO2) underground.

Carbon dioxide is one of several known greenhouse gases (GHG) that contribute to global warming.

“In a greenhouse gas limited economy and with Wisconsin’s reliance on coal for electric generation, carbon sequestration makes sense.” said PSC Commissioner Mark Meyer.

"Wisconsin is in a strong position to support ongoing carbon sequestration efforts and collaborate with other states and regions in making carbon sequestration possible.”

Key findings of the Study Group include:

+ Several promising technologies are being developed and tested for capturing carbon dioxide emissions from power plants.
+ Carbon dioxide can be captured either pre- or post-combustion, depending on the type of power plant, and compressed for transport and sequestration.
+ Long-distance transport of carbon dioxide is a proven, viable option with over 3,000 miles of pipeline already in use for this purpose nationwide.
+ Wisconsin should consider a holistic approach to carbon sequestration that addresses both the public and private interests involved and will allow Wisconsin to work effectively and efficiently with adjacent states to implement proposed projects.
+ Wisconsin may benefit long-term from the further exploration and development of CO2 storage in the region; however, it is not very likely to happen in the short-term (2 to 5 years) or mid-term (5 to 20 years).

The final report also includes analysis of three potential scenarios in which carbon from generating facilities serving Wisconsin customers could be captured, transported and sequestered.
