CO2 UTILZATION & GEOLOGICAL STORAGE
What Are Key Challenges & Risks in Geologic Storage?
We can help during the project lifecycle of storage project

The CO2 utilization and underground storage options are of three types:

  1. CO2 utilization in Enhanced Oil Recovery (EOR) in depleted oil & gas reservoir (called CO2-EOR).

    • Most mature; well established since 1970's. Capturing CO2 from NG processing plants

    • Least regulatory challenges

    • Required Class II well permit (delegated to states (42) )

    • Larger number of wells poses leakages risks but equally offer opportunity to gather data

    • Qualify for federal 45Q credits ($35 by 2026)

    • SACROC unit in Texas successful example of CO2-EOR sInce 1970'

2. CO2 storage in depleted oil & gas reservoirs (dedicated CO2 storage - No EOR)

  • Less mature and more possible regulations

  • Required Class-VI Well permit (Regulated by EPA in all states except N. Dakota)

  • Larger number of wells poses leakage risks but equally offer opportunity to gather data

  • Qualify for federal 45Q credits ($50 by 2026)

  •  

 3. CO2 storage in saline aquifer (Dedicated CO2 storage - No EOR)

  • Least  mature and highly regulated. Several risks and uncertainties

  • Required Class-VI Well permit (Regulated by EPA in all states except N. Dakota)

  • Few number of wells poses lower leakage risks but fewer opportunities to gather data

  • Qualify for federal 45Q credits ($50 by 2026)
