The Cost of Carbon Geo-Sequestration

Some guidance to the cost of carbon geo-sequestration is obtained by consideration of the costs of using carbon dioxide in enhanced oil recovery schemes . This is in the region of 20-25/tonne of carbon dioxide after purchase of the gas for this duty. 

In order to give an informative account of the likely cost of carbon abatement of the various petrochemical operations, the carbon emissions have been estimated and a fixed variable relationship developed with carbon dioxide disposal cost as the variable. This cost can be either the cost of geo-sequestration facilities, the cost of purchasing emissions certificates or carbon tax. 

A final note is that some facilities inject both hydrogen sulphide and carbon dioxide from acid gas plants making it feasible to dispose of both gases simultaneously.
