CCUS Full-Chain Economics
Levelized cost of CCUS: capture (CAPEX + OPEX) + transport + storage. Outputs $/tCO₂ captured and $/tCO₂ avoided (accounting for parasitic emissions). Includes 45Q tax credit (post-IRA: $85 saline / $60 EOR / $180 DAC).

Engineering Basis

  • Capital recovery: CRF = r(1+r)ⁿ / ((1+r)ⁿ − 1).
  • Typical $/t captured (DOE NETL): NGCC ~$58, USC coal ~$58, industrial $50-100, DAC $200-600.
  • Transport $1-3/t/100km for trunk dense-phase pipelines (NPC 2019).
  • Storage $5-25/t including MMV (Monitoring/Measurement/Verification).
  • 45Q post-IRA: $85/tCO₂ saline, $60/tCO₂ EOR, $180/tCO₂ DAC, $130 DAC EOR.
  • Standards: DOE NETL Cost & Performance Baseline (2022), IEAGHG, NPC 2019, IRS 45Q, IPCC SR-CCS.
