Carbon Dioxide (CO2) is utilized by industry to enhance oil recovery. Subsurface CO2 storage could significantly impact reduction of CO2 emissions to the atmosphere, but the economics and potential risks associated with the practice must be understood before implementing extensive programs or regulations. Utilization of other energy-related gases such as helium (He), if separated and concentrated from the produced natural gas stream, can make otherwise low-thermal (un-economic) natural gas deposits a viable part of the national natural gas resource base. Geologic energy storage options require additional investigation and assessments of available storage resources.
Federal Lands Greenhouse Gas Emissions and Sequestration in the U.S.

How does carbon get into the atmosphere?
Atmospheric carbon dioxide comes from two primary sources—natural and human activities. Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.Learn more: Sources of Greenhouse Gas Emissions (EPA)
Has the USGS made any Biologic Carbon Sequestration assessments?
The USGS is congressionally mandated (2007 Energy Independence and Security Act) to conduct a comprehensive national assessment of storage and flux (flow) of carbon and the fluxes of other greenhouse gases (including carbon dioxide) in ecosystems. At this writing, reports have been completed for Alaska, the Eastern U.S., the Great Plains, and the Western U.S. Learn more: Land Change Science...
How much carbon dioxide does the United States and the World emit each year from energy sources?
The U.S. Energy Information Administration estimates that in 2019, the United States emitted 5,130 million metric tons of energy-related carbon dioxide, while the global emissions of energy-related carbon dioxide totaled 33,621.5 million metric tons.
Which area is the best for geologic carbon sequestration?
It is difficult to characterize one area as “the best” for carbon sequestration because the answer depends on the question: best for what? However, the area of the assessment with the most storage potential for carbon dioxide is the Coastal Plains region, which includes coastal basins from Texas to Georgia. That region accounts for 2,000 metric gigatons, or 65 percent, of the storage potential...
How much carbon dioxide can the United States store via geologic sequestration?
In 2013, the USGS released the first-ever comprehensive, nation-wide assessment of geologic carbon sequestration, which estimates a mean storage potential of 3,000 metric gigatons of carbon dioxide. The assessment is the first geologically-based, probabilistic assessment, with a range of 2,400 to 3,700 metric gigatons of potential carbon dioxide storage. In addition, the assessment is for the...
What’s the difference between geologic and biologic carbon sequestration?
Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. This method of carbon storage is also sometimes a part of enhanced oil recovery, otherwise known as tertiary recovery, because it is typically used later in...
What is carbon sequestration?
Carbon dioxide is the most commonly produced greenhouse gas. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. The USGS is conducting assessments on two major types of carbon sequestration: geologic and biologic.

Economics of Energy Transitions
This task conducts research to characterize or evaluate the economics of developing technologies or markets in geologic resources. Such research can analyze the relative risks, costs, and benefits from the utilization and not just the extraction of underground resource. Economic analysis builds upon the geologic resource assessment work by other tasks in the Utilization of Carbon and other Energy...Geologic Energy Storage
The United States (U.S.) domestic energy supply increasingly relies on natural gas and renewable sources; however, their efficient use is limited by supply and demand constraints. For example, a) in summer, natural gas production may outpace home heating fuel demand and b) in daytime, wind and solar electricity production may outpace industrial power requirements. Storing rather than dumping...Assessing Emissions from Active and Abandoned Coal Mines
The gas emission zone liberates and accumulates significant amounts of coal mine methane as a by-product of active mining. In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone. As a consequence, a large amount of gas migrates into...Induced Seismicity Associated with Carbon Dioxide Geologic Storage
As a national science agency, the USGS is responsible for assessing hazards from earthquakes throughout the United States. The USGS studies induced seismicity across the spectrum of energy issues: carbon sequestration, geothermal energy, and conventional and unconventional oil and gas. In the central and eastern United States, earthquakes induced by fluid injection activities contribute...Geologic Carbon Dioxide and Energy-related Storage, Gas Resources, and Utilization
The objectives of this task are to conduct relevant research needed to 1) evaluate helium (He) and CO2 resources; 2) support future assessments of low-thermal gases and better understand their resources and potential for use as analogues for anthropogenic CO2 storage; 3) study the feasibility of large-scale CO2 mineralization in the United States; 4) develop pressure-limited dynamic models for...Methodology Development and Assessment of National Carbon Dioxide Enhanced Oil Recovery and Associated Carbon Dioxide Storage Potential
