Carbon Storage - Geologic Storage Technologies and Simulation and Risk Assessment


Zero Emissions Research and Technology (ZERT) II - Investigating Fundamental Scientific Issues Affecting the Long-Term Geologic Storage of Carbon Dioxide


Performer: Montana State University

Project No: FE0000397


Project Description

This project focuses on the basic science and development needs for improving the state of knowledge of carbon dioxide (CO2) behavior in the subsurface. The project is assessing knowledge gaps in fundamental physical and chemical properties in relevant systems, making measurements of those properties, improving numerical models by improving parameterization using these studies and by extending code capability, and testing efficacy and detection limits of monitoring, verification, and accounting techniques. This information and the improved techniques are being incorporated into a systems-level model for risk assessment.

To date, investigations into geologic sequestration point to great promise, but large issues remain before it can be implemented on a widespread basis. Primary among these are matters related to CO2 retention in subsurface sinks, including an accurate determination grounded in basic science of what levels of retention are attainable in different geologies; impact of those levels on climate change; development of loss mechanism mitigation strategies; risk assessment, and development of Monitoring, Verification, and Accounting (MVA) tools and methods that can work for low escape levels.
