The New York state Energy Research and Development Authority and about a dozen energy companies, including AES East Energy and Nornew Inc., are set to study sequestration sites during a three-year program that will cost $4 million. The program will begin this summer with geologists studying parts of the Southern Tier, in particular the old natural gas wells. Other sites in western New York will also be examined to determine the extent to which they can store carbon dioxide. The goal is to see if the CO2 can be sequestered between 2,500 and 10,000 feet underground.

The state also announced it would be joining the Midwest Regional Carbon Sequestration Partnership, which is funded by the United States Department of Energy.
