ECONOMICS & FINANCE
At early stage of project development, CAPEX and OPEX estimates are given with a +/- 30% accuracy.
Costs are calculated either on the captured CO2 volumes or on the avoided one (see carbon footprint calculation).
For pipeline transport, the cost supposes dehydrated CO2 at 150 bar (roughly 2175 psi). For boat transport, liquid CO2 is supposed before loading at -50°C (-58°F) and a pressure of 6.5 bar (roughly 94 psi) for low pressure transport and at or above 75 bar (1088 psi) for super-dense transport.
With regards to storage projects, investment needs can be calculated for characterization, additional facilities for the injection operations (wells, buffer surface storage, MMV), post closure monitoring, and plugging and abandoning old wells if the risk analysis has shown relevant to do so.
For CO2-EOR projects, revenues from incremental oil recovery can be estimated.
For all elements of the CCS chain, dismantling & safety management costs are assumed.
Geogreen economic analyses are performed based on Discounted Cost Cash-Flow, Levelized Cost of Production, or Net Present Value methods.
