Carbon Capture and Geologic Sequestration
CCS is a method of capturing carbon dioxide from large point sources and storing it in such a way that it never
enters the atmosphere
Major outcomes of carbon capture and geologic sequestration
1. Stable sequestration, where the CO2 is stored through mineral, hydrodynamic or solubility trapping. The trapped CO2 then remains stored within the reservoir boundaries at a consistent pressure and temperature.
2. Fracturing, some CO2 trapping may occur, but pressure and temperature of the reservoir exceed acceptable conditions and the caprock seal is fractured, releasing CO2 gas outside of the reservoir.
3. Viscous fingering, some CO2 trapping may occur, but the CO2 is less buoyant than the existing pore waters and can thus migrate out of the boundary layers.
The Need for a Regulatory Framework
Health and safety regulators need a solid understanding of geological performance in a variety of geological settings and reservoir types in order to design monitoring and remediation requirements
Permitting and acquisition of storage rights rests on adequacy of models to accurately project geological storage capacity, plume size and behavior
Monitoring methodology and remediation techniques to trust that any leakage could be detected and remediated

Management Through Private Standards
Industry developed, consensus based ISO, ANSI, ASTM International, IEEE, CSA,
USGBC International in scope
Provide an industry-wide code Kyoto CDM certifications
Government regulators often give voluntary standards the force of law by citing them in laws, regulations, and codes. 1995 passage of the National Technology
Transfer and Advancement Act (Public Law 104-113) requires government agencies to use privately developed standards whenever it is at all possible
Example to Follow: Natural Gas Transportation Standards
ASTM D2513 - 11e1 “Thermoplastic Gas Pressure Pipe, Tubing, and Fittings” transformation from a near-exclusive metallic
distribution piping network to a near-exclusive thermoplastic piping distribution network
saved US natural gas utilities in excess of $10 Billion in installation and maintenance costs.

Hydrostatic Design Basis (HDB), Strength Design Basis (SDB), Pressure Design Basis (PDB) or Minimum Required Strength (MRS) Ratings for Thermoplastic Piping Materials or Pipe”
Proposed Standards Risk-based Performance Standards. Regulatory
scheme that will tailor project requirements to specific risks posed by a particular project
Transportation: transport as supercritical CO2 by pipelines, less than 5% fugitive emissions, pipeline length governed by the pressure drop equation
Site selection: siting locations following drinking water criteria
Site operations/closure: Reevaluation of the Area of Review every 5 years in order to address concerns about the inherent uncertainties in modeling CO2 movement
Long-term stewardship: monitoring and reporting techniques contingent with clean air criteria
