Abstract
A system and method for the delivery of cryogenic fluid, more particularly a cryogenic fuel, such as, for example, but not limited to an liquified natural gas (LNG), to a cryogenic fluid using source, and more particularly an LNG fuel source, and even more particularly an LNG fuel-operated engine. The system includes a source of a cryogenic fluid, more particularly an underground tank and with a liquid level within the underground tank source. The system includes a delivery pump to deliver cryogenic fluid from the underground tank source, to a cryogenic using source, typically an LNG fuel source above the underground tank source, with the pump located below the liquid level of the cryogenic fluid in the cryogenic fluid fuel tank. The system includes a sump containing cryogenic fluid, and the delivery pump positioned and immersed in the cryogenic liquid in the sump, and a conduit and valve to deliver cryogenic fluid through the use of the cryogenic fluid flow pump from the underground cryogenic fluid tank source to an above-ground or level using source, such as an LNG operated vehicle.
