Abstract: A CO2 energy storage system includes a storage tank that stores a CO2 slurry, including dry ice and liquid CO2, at CO2 triple point temperature and pressure conditions. The storage system also includes a first pump coupled in flow communication with the storage tank. The first pump is configured to receive the CO2 slurry from the storage tank and to increase a pressure of the CO2 slurry to a pressure above the CO2 triple point pressure. The energy storage system further includes a contactor coupled in flow communication with the first pump. The contactor is configured to receive the high pressure CO2 slurry from the pump and to receive a first flow of gaseous CO2 at a pressure above the CO2 triple point pressure. The gaseous CO2 is contacted and then condensed by the melting dry ice in the slurry to generate liquid CO2.

Abstract: A sensor deployment system for positioning within a well casing is provided. The sensor deployment system includes a deployment shuttle comprising a first end, a second end, and an inner surface and an outer surface extending between the first end and the second end. The inner surface is configured to define a channel between the first end and the second end. A sleeve is coupled to the outer surface and configured to move relative to the well casing. A wire support is coupled to the inner surface and extending into the channel.
