The Saline Storage Cost modelling workshop aims to increase understanding between energy market modelers of i) the uncertainty of geologic storage properties in various basins in the US; ii) the state-of-the-art in approaches/models used to estimate storage costs; iii) the uncertainties in cost-predictions along with the factors driving the uncertainties; and iv) impacts from decisions on financial responsibility for Post-Injection Site Care (PISC) and long-term storage liability). The workshop will bring together a range of stakeholders including modelers, saline storage SMEs, project developers, storage industry representatives, regulators, and insurers to share knowledge about potential saline storage projects.
