Current Research ProjectsQuantify the risk and potential liabilities of CO2 leakage from geologic CO2 storage projectsThis three-year project — performed in partnership with Princeton University and the University of Minnesota — will develop a framework to examine geologic carbon sequestration (GCS) investment decisions in light of uncertainty in CO2 leakage risks, potential subsurface liability, and the associated losses in carbon credits. The project team will use this framework to quantify damages that derive from interferences with competing subsurface resources; identify regulatory, and liability management alternatives; and determine the role of geochemical reactions in affecting the probability of CO2 leakage through alteration of the integrity of caprocks and well cements. (DOE project fact sheet) Behavior of Nanoparticles in the EnvironmentThis project addresses the need to understand the catalytic activity, reactivity and transport of metal oxide and metallic nanoparticles in soils and aquifers. The rapid increase in the use of engineered nanoparticles, which will result in their incidental release to water resources and their deliberate release for environmental remediation, necessitates fundamental a priori knowledge of their environmental fate and impact in order to properly assess related social implications. This research will produce knowledge about nanoparticle chemistry in soils that is necessary to determine what steps, if any, should be taken to limit the release of engineered nanoparticles into the environment.
