Definition of Hypothetical Impact Scenarios for CO2 Storage Sites: An Input to the RISCS Project

Scenarios were developed jointly by all project partners at an expert workshop, and subsequently during reviews of the workshop report. The workshop outcomes were audited against established lists of Features, Events and Processes (FEPs) relevant to storage systems, and compared with issues and uncertainties identified for other project activities. The work produced a small number of scenarios that broadly represent the main types of impacts that could occur. A distinction is made between marine and terrestrial environments (Table 1). Within each type of environment, receptor types and habitats will primarily vary according to climate (terrestrial environments) and water depth, salinity and temperature (marine environments), although other factors will also be relevant.
