Carbon Capture & CO₂ Compression Equipment calculator

Retrofit Payback Calculator

Estimate simple payback for adding or upgrading carbon capture, CO₂ compression, drying, heat recovery, monitoring, or storage-interface equipment. Try a pessimistic case and an optimistic case to bracket the answer for the steering committee.

What this calculator does

  • Estimate simple payback for adding or upgrading carbon capture, CO₂ compression, drying, heat recovery, monitoring, or storage-interface equipment.
  • Use it when retrofit payback in carbon capture and co₂ compression equipment is being put in front of a capital committee and the savings story needs to hold up.
  • Turns carbon capture retrofit investment, annual avoided-emissions value or savings, annual retrofit support cost into a payback period for retrofit payback in carbon capture and co₂ compression equipment.

Formula used

  • Net annual retrofit value = annual avoided-emissions value or savings - annual retrofit support cost
  • Carbon capture retrofit payback period = carbon capture retrofit investment ÷ net annual retrofit value

Inputs explained

  • Carbon capture retrofit investment: Include equipment, installation, integration, controls, civil work, commissioning, permitting support, and contingency.
  • Annual avoided-emissions value or savings: Use carbon credits, avoided carbon cost, energy savings, production value, or contract revenue expected each year.
  • Annual retrofit support cost: Include maintenance, solvents, sorbents, water, electricity, MRV, testing, service, and reporting costs not netted from savings.

How to use the result

  • Use it when retrofit payback in carbon capture and co₂ compression equipment is going to a capital review.
  • The model assumes savings hit on day one. Real savings ramp; bake that into your case for the committee.

Common questions

  • What problem does this retrofit payback calculator solve? Estimate simple payback for adding or upgrading carbon capture, CO₂ compression, drying, heat recovery, monitoring, or storage-interface equipment. You get a payback period you can defend before quoting, scheduling, or sign-off.
  • Where do I get the inputs for this carbon capture and co₂ compression equipment calculator? carbon capture retrofit investment, annual avoided-emissions value or savings, annual retrofit support cost usually move the payback period most. Pull from measured carbon capture and co₂ compression equipment runs, supplier data, and recent quotes rather than memory.
  • How should I use the result? Compare payback to your hurdle rate; if it is over the line, kill it now instead of after a pilot.
  • What should I verify first? Confirm support cost includes spares, software, and the headcount needed to keep the system running.
