Abstract
Given the current projections of our energy mix for the next 50 years and longer, fossil fuels will still be a major energy source. If we are to reduce our greenhouse gas emissions to levels suggested by the Intergovernmental Panel on Climate Change (IPCC) and others, then carbon dioxide sequestration will likely be a necessity. However, before injecting massive volumes of CO2 into the ground, the public, as well as the private companies who perform the injections and certify the permanent storage of CO2, will need assurance that sequestration is safe and effective. Various monitoring, modeling, and mitigation techniques will need to be developed to deal with the risks inherent in CO2 sequestration. This talk addresses the risks involved in putting millions of tons of carbon dioxide underground, addresses the change in risk over time, and discusses many of the monitoring and mitigation technologies for CO2 sequestration that are currently under development.
