Abstract

A method for dispensing liquefied fuel, the method including: providing a non-petroleum fuel as a liquefied fuel to a storage tank; increasing pressure of the liquefied fuel to a target pressure usinga pump disposed within the storage tank, wherein a first portion of the liquefied fuel is bypassed around or at least partially around a heat exchanger, and a second portion of the liquefied fuel isdischarged to the heat exchanger, wherein the heat exchanger is configured to warm the second portion of the liquefied fuel. A dispenser is provided that incorporates a control system that allows coordinated fueling of one or more vehicles simultaneously, where the heat exchanger uses only the fuel itself without external refrigeration to manage final dispensing temperature and the fueling stationdoes not include a storage subsystem disposed between the pump and the dispenser.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 62 / 768,150, filed November 16, 2018, entitled "Method and System for Distributing Liquefied Gas," and the filing on September 20, 2019, entitled "Method and System for Distributing Liquefied Gas" of U.S. Application No. 16 / 576,904, which is incorporated herein by reference. technical field [0003] The present invention relates to methods and systems for distributing liquefied gas, and more particularly, to methods and systems for distributing liquefied hydrogen or liquefied natural gas. Background technique [0004] Most current hydrogen refueling stations use gaseous hydrogen supplies, which are expensive to transport and difficult to scale up into larger hydrogen refueling stations or networks of hydrogen refueling stations due to maintenance and capital costs. For example, gas compression in general, and hydrogen compression in particular, is energy intensiv...
