Subsea high-pressure liquid carbon dioxide storage

摘要

A subsea high-pressure liquid carbon dioxide storage equipment includes a carrier 101 for holding and carrying high-pressure liquid carbon dioxide; a water-surface power supply equipment 130 arranged on the surface of the water to supply power; a subsea storage equipment 120 having high-pressure liquid carbon dioxide stored therein; a relay flotation tank 110 having high-pressure liquid carbon dioxide stored therein; and an undersea injection pump 140 configured to inject high-pressure liquid carbon dioxide into an undersea storage base 100 and fixedly provided in the seabed. The storage equipment 120 may comprise a buoyancy controller using seawater influx and discharge pumps to regulate the buoyancy of the storage tank 120. The storage installation may feature measuring units or sensors to measure the amount of liquid CO2 and non-condensable gases in the storage space 100.
