CO2 Storage Pilot Study for Lignite Coal
The United States possesses abundant unminable lignite resources that havepotential as storage sites for carbon capture and storage (CCS). However, feasibility ofCO2 storage in lignite coal has yet to be proven. The Plains CO2 Reduction (PCOR)Partnership has developed a lignite field validation test in Burke County, North Dakota,to investigate the feasibility of carbon dioxide storage in unminable lignite seams. ThePCOR Partnership is one of seven regional partnerships investigating CCS funded by theU.S. Department of Energy and commercial sponsors.This paper will present methodology and results from the Energy & EnvironmentalResearch Centers lignite field validation test. The results include crosswell seismicimaging of injected CO2, downhole sensor measurements, and monitoring. The technicalfeasibility and economics of carbon storage in lignite coal largely depend on adequateCO2 trapping, adsorption, storage capacity of the reservoir, injectivity, and land surfaceaccess. The work presented provides a greater understanding of injectivity, trapping,adsorption, and storage capacity for lignite coal.View/Download Document
