Sensor and Tracer Technology for Characterization of Ultra-Low CO2 Leakage Fluxes (Amonette CMI LDRD, PNNL Scope #90001)
EMSL Project ID
4295
Abstract
The DOE is funding a number of geologic sequestration demonstration projects that will involve injection of as much as 100,000 MT of CO2 into deep geologic formations. Leakage rates from these reservoirs must be shown to be <0.1% of stored volume per year if these projects are to assist the DOE in demonstrating deep geologic sequestration as an effective climate change mitigation technology. However, the relatively high background levels of CO2 present in the atmosphere and soil, coupled with their seasonal and diurnal variability, makes immediate detection of such small CO2 leakage rates with currently existing technology extremely difficult if not impossible.In this project, we will identify and prioritize potential chemical and radiological tracers suitable for monitoring leakage of CO2 from deep geologic formations. We anticipate using both types of tracers at a demonstration site to ensure accurate monitoring of leakage. Two types of sensors will be developed for detection of the selected tracers, a laser photoacoustic spectroscopic sensor and a scintillating-grid radiometric gas sensor. Both sensors offer compactness and extremely low potential detection limits. Finally, the developed sensors will be evaluated for potential use in a field demonstration designed to challenge the theoretical framework for testing CO2 leakage through porous media and assess the utility of the combined tracer(s) and sensor(s) to detect and characterize CO2 leakage from a deep geologic formation.
