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 regional CO2 storage assessments and economic evaluations; and 5) evaluate geologic energy storage resources. 

Utilization of other energy-related gases such as CO2, He, nitrogen (N2), and hydrogen sulfide (H2S), if separated and concentrated from the produced natural gas stream, can make otherwise low-thermal (un-economic) natural gas accumulations a viable part of the national natural gas resource base. Many of these gases, including CO2, are separated and vented at the production site (H2S is typically reinjected), thereby contributing greenhouse gas to the atmosphere. Similarly, methane emissions during coal mining and after mine closure are often released to the atmosphere and contribute to greenhouse gases instead of being captured and utilized for energy production. The national electrical grid requires a balance between supply and demand across daily to annual cycles. Subsurface energy storage mechanisms including compressed air or gas, pumped hydroelectric, and geothermal require additional geologic investigations and assessments of available storage resources. To address an all-of-the-above approach, this project works to build improved geologic models needed to describe the distribution and resource-potential of these various energy options.
 
This task plans to complete a national assessment of He and CO2 resources found in natural gas reservoirs. New field and natural gas geochemistry data collected by task staff will be compiled and interpreted for scientific journal publications. Models of natural CO2 leakage of stored CO2 into shallow aquifers will be developed. A report describing the feasibility of large-scale CO2 mineralization in the United States was completed in 2019. In addition, engineering and economic modeling will be used to better characterize pressure-limited geologic CO2 storage resources. The task will evaluate the datasets and key process steps required to build a probabilistic assessment methodology to assess various geologic subsurface energy storage options that are available for use by the U.S. energy industry.
