CO₂ capture pre-design tool
Sizes a NaOH absorption column and the electrochemical cell that regenerates the solvent, and computes the cost of capturing each tonne. Every number says where it comes from.
Pre-feasibility (AACE class 5): for comparing options and orders of magnitude, not an engineering design.
Results
No combination in the scan reaches the capture target: the closest one is shown.
Where does the cost go?
Cost of capture versus electricity price
The same design at other electricity prices. The dashed line is your price; 0.018 USD/kWh was Colombia's 2024 solar auction price.
Inside the column
Gas rises from the bottom (height 0) and fresh solvent enters at the top.
