Claim:
1. An underwater gas pressurization unit comprising: at least one vertical vessel arranged to receive gas through a top of the vessel and a pressurizing liquid through a bottom of the vessel, and further comprising a layer of water- immiscible liquid upon a layer of aqueous salt solution, wherein a density of the pressurizing liquid is higher than a density of aqueous salt solution, which is in turn higher than a density of the water-immiscible liquid, to maintain the layer of aqueous salt solution on top of the pressurizing liquid and to maintain the layer of water-immiscible liquid on top of the layer of aqueous salt solution, and a valve system arranged to pressurize the gas by introducing the pressurizing liquid into the vessel, evacuate the pressurized gas through the top of the vertical vessel upon reaching a specified pressure and introduce gas into the vessel by evacuating the pressurizing liquid through the bottom of the vertical vessel, wherein the gas is continuously pressurized by the introducing and the evacuating of the pressurizing liquid, and wherein the pressurizing liquid comprises at least one completely or partially halogenated hydrocarbon of the alkane homologous series,
