The investment cost for the EGCS unit ranges between $1,3 million-$2,5 million, depending on vessel type. Installation costs of approximately $1 million must be expected, depending on yard. Estimated operating cost for the scrubber is $20-$50 per metric ton fuel consumed by the scrubber, depending on caustic soda (NaOH) and fuel price, fuel Sulphur level and scrubber operating mode.

approximate payback time
* The spread between compliant fuel and HSFO is assumed to be USD 250 per tonne fuel. Estimated cost is $20-50 per tonne fuel consumed by scrubber combustion units. Fuel cost is depending on caustic soda and fuel price, fuel Sulphur level and scrubber operating mode. In this example we have used a fuel cost of $40 per tonne fuel.
Approximately 1 year payback time
If assuming a spread of $350 per metric ton price difference between MGO (0.1% Sulphur content) and HFO, 10,000 metric tonnes of yearly fuel consumption, and total investment cost of $ 4,5 million, the approximate payback time is 1 year (ROI will vary according to yearly fuel consumption and fuel spread).
The installation of an EGCS is the most cost-effective solution to meet the IMO Sulphur regulations. All exhaust sources on board, including boilers, can be served by one common EGCS unit, enabling a fast return on investment.
