More than 1, 100 years of CO2 storage potential in Geologic Formations
Washington, D.C. — Yale University has been selected by the U.S. Department of Energy to develop technologies aimed at safely and economically storing carbon dioxide in geologic formations. Energy Secretary Steven Chu said the DOE is awarding a total of 15 projects up to $21.3 million over three years to help develop the technology and infrastructure to implement large-scale CO2 storage in different geologic formations across the nation.
The projects selected will support the goals of helping reduce U.S. greenhouse gas emissions, developing and deploying near-zero-emission coal technologies and making the U.S. a leader in mitigating climate change.
“The projects announced today are part of this Administration’s commitment to leading the world in carbon capture and storage technology,” Chu said. “These projects will reduce greenhouse gas emissions, develop clean energy innovation and help produce jobs for Americans across the Nation.”
The Connecticut based project selected for award:
- Yale University (New Haven, Conn.) — Yale University will study basic questions about the chemical and mechanical processes that must occur in basalt reservoirs for carbonation to be practical on a large scale. Experiments will address the question of whether the in situ reaction can sustain itself by generating cracks, or will shut itself down by constricting the pore space. The study is designed to provide a basis for scaling up to future field tests of mineral carbonation in basaltic reservoirs. (DOE share: $1,597,187; Duration: 36 months)
Geologic storage is currently focused on five types of formations: (1) depleted oil and gas reservoirs, (2) deep saline formations, (3) unmineable coal seams, (4) oil- and gas-rich organic shales, and (5) basalts. Carbon storage in depleted oil and gas reservoirs can also increase oil or gas production, while storage of CO2 in deep saline formations holds the promise of enormous worldwide capacity, with estimates of thousands of gigatonnes of storage.
Efforts are underway to demonstrate safety and permanence of geologic sequestration through initiatives such as the Department of Energy’s Regional Carbon Sequestration Partnerships. The 15 selected projects will complement ongoing efforts by developing and testing technologies that address critical challenges for geologic storage including injectivity of CO2 into the reservoir, storage capacity, plume migration, and containment by caprock and other trapping mechanisms.
