What a DOC plant costs,
within reason.
The ranges we plan against, and a model you can adjust.
Four inputs move the answer.
Power price and CAPEX dominate. Transport and storage and stack replacement are second order.
| CAPEX | 60–80 M USD |
|---|---|
| Power price | 42–77 USD/MWh |
| Electricity use | 3.0–3.2 MWh per tonne of CO₂ |
| Transport and storage | 50–70 USD per tonne |
| Full cost | 450–550 USD per net tonne (estimated) |
Assumptions: 50,000 t/yr gross, ~43,000 t/yr net, 20 years, 50% debt at 3%, stack replacement USD 30/t, maintenance 2% of CAPEX.

What moves the result
A 20% change in power price or CAPEX moves returns more than any other input. Transport, storage and stack replacement are second order.
