Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods are provided. Gas is compressed hydraulically by a rising pressurization liquid that is separated from the gas by a water immiscible liquid layer on top of an aqueous salt solution. Tall vessels are used to reach a high compression ratio that lowers the liquefaction temperature. The pressurizing liquid is delivered gravitationally, after gasification, transport to smaller water depths and condensation. Cooling units are used to liquefy the compressed gas. A cascade of compression and cooling units may be used with sequentially higher liquefaction temperatures, which allow eventual cooling by sea water. The pressurizing liquid, dimensions of the vessels, the delivery unit, the coolants and the implementation of the cooling units are selected according to the sea location, to enable natural gas liquefaction in proximity to the gas source.

Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods and gas field development methods are provided. Gas is compressed hydraulically by seawater introduced into vessels and separated from the gas by a water immiscible liquid layer. Tall, possibly vertical helical vessels are used to reach a high compression ratio that lowers the liquefaction temperature. Cooling units are used to liquefy the compressed gas, possibly by a coolant which is itself pressurized by a similar mechanism. The coolant may be selected to be liquefied under surrounding seawater temperatures. The seawater which is used to pressurize the gas may be used after evacuation from the vessels to pressurize intrastratal gas in the production stages and broaden the gas field development.
