The FE/NETL CO2 Saline Storage Cost Model estimates costs to store a tonne of CO2 in a saline reservoir. The model estimates costs associated with a project, using simplified geo-engineering equations to calculate reservoir values needed to determine injection well costs, monitoring costs, financial responsibility costs, etc. All of these costs are summed over the life of a CO2 storage project and discounted to a NPV of near zero to determine the first-year break-even cost to store a tonne of CO2. The FE/NETL CO2 Saline Storage Cost Model (2017): User's Manual provides some details on the use of this model.
