That's a very good question, and I don't think anyone has any answers to that question at this point in time. There certainly has been a fair amount of testimony recently in the United States and concern about U.S. drinking water and how capturing carbon and putting it in deep saline aquifers might impact groundwater over time. It is an area that requires serious investigation.
Another area of critical interest, in terms of water and carbon capture and storage, is related to the fact that carbon capture and storage is largely a technology that has been designed for coal-fired plants. It will require 30% more energy to capture that carbon and store it. If coal-fired plants are using and burning more coal and using more energy to do this, they will require more water for cooling. So there are implications for water.
