CHAMPAIGN (AP) – The University of Illinois is getting a roughly $900,000 grant to study the possible environmental impact of storing the chief man-made greenhouse gas under water reservoirs.
The EPA grant covers what could be a three-year research project involving subsurface storage called sequestration.
The plan is to see if injecting carbon dioxide from coal-fired power plants could cause changes in reservoir pressure. They want to see if that could cause saltwater to migrate from deeper groundwater and contaminate fresh water near the surface.
Underground injection of CO2 for such things as enhanced oil and gas recovery is a long-standing practice.
