Utah is 'blessed' with good sites for carbon sequestration, and the Utah Geological Survey has received a Department of Energy grant to map them out.
Carbonates like limestone are another material that can absorb carbon dioxide, and the Paradox Basin in southeastern Utah, where the limestone is capped by impermeable salt formations, also has potential, Vanden Berg said. The basin includes Bears Ears National Monument and other areas that could also draw opposition from conservationists.
The Bears Ears buttes on April 10, 2021. The Bears Ears National Monument lies within the Paradox Basin in southeastern Utah. The basin has areas where the geology may be suitable for carbon sequestration.UGS’s depository of material pulled from drill sites around the state. There could be some limited field work in areas where there isn’t much deep-drilling history, such as the West Desert, he said.
Utah by itself generates about 60 million tons of carbon dioxide annually, and, theoretically, the state has the capacity to store all that and more. But theory is a long way from practice. For instance, there is no practical way to capture and store the carbon dioxide produced by gasoline and diesel cars and trucks, which produce more than a third of that CO2.
The grant is aimed at identifying potential sites for sequestering without much regard to how the CO2 might be collected and delivered to the sites. “We’re mostly focused on the storage component of the carbon capture and storage. We’re not so much on the capture side,” Vanden Berg said. Most carbon capture under discussion involves collecting it at a major source, like a power plant or a cement factory. It’s expensive. The tax credits reduce, but do not completely offset those costs. said carbon capture on coal-fired power plants nearly doubles the water needed to operate the plants.Three of Utah’s four large coal-fired power plants now have scheduled closing dates in the next decade, meaning they are unlikely to add carbon capture over that short term.
