Carbon Capture & CO₂ Compression Equipment worked example

Capture Cost per Ton at 92% cost scope included: a worked example

This scenario runs the capture cost per ton calculation on the strong side: 92% cost scope included, with every other input held at its documented default. Use it when capture cost per ton in carbon capture and co₂ compression equipment is being put through a carbon capture and co₂ compression equipment weighted-cost review.

The inputs for this scenario

  • CO₂ captured in period: 100 t CO₂ (unchanged)
  • Variable capture cost: 45 $ / t CO₂ (unchanged)
  • Cost scope included: 92 % (raised for this scenario; the documented default is 80)
  • Fixed capture cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable capture cost subtotal = CO₂ captured in period × variable capture cost × cost scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total capture cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for capture cost per tonne co₂.
  • At this operating point the engine returns 4,140 $ for variable capture cost subtotal.
  • At this operating point the engine returns 250 $ for fixed capture cost.

How this compares with the baseline

  • Against the tool's baseline example, where cost scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it to benchmark a capture technology, set a break-even credit price, or compare cost across operating periods. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total capture cost: 4,390 $ (headline result)
  • Capture cost per tonne CO₂: 43.9 $ / piece
  • Variable capture cost subtotal: 4,140 $
  • Fixed capture cost: 250 $

Run it with your numbers

  • Every input above is editable in the live Capture Cost per Ton calculator, which recalculates instantly and can be shared with the inputs intact.
