Long-term Protection of Freshwater Resources
The subsurface geologic storage of carbon dioxide (CO2) represents a primary option for achieving reduced greenhousegas emissions to the atmosphere. Two factors are important to successful commercial deployment: 1) good site selectionand 2) implementation of both conventional and innovative monitoring methods, which will ensure that active carboncapture and storage (CCS) operations are performing properly. Equally important to commercialization is the ability toprovide assurances that negative impacts to human health and the environment will not occur in the future.The Regional Carbon Sequestration Partnerships (RCSPs) Water Working Group (WWG) has been using knowledgeand experience gained from the RCSPs to understand how CO2;containment in the subsurface can be achieved whileensuring protection of freshwater resources. Research conducted by the RCSPs has provided insight both on the types of CO2-trapping mechanisms prevalent in CO2;storage reservoirs as well as strategies to make use of these mechanisms instorage formations across the United States. These mechanisms include structural/stratigraphic, hydrodynamic, mineral,residual-phase, and solubility trapping. WWG is also identifying best practices for water management during CCS,including the long-term protection of freshwater resources. WWG has produced a fact sheet that highlights these effortsto aid in making all stakeholders of the CCS industry aware of work that is currently under way. WWG is also partneringwith the IEA GreenView/Download Document
