Liquid hydrogen storing and fueling station

Abstract

A liquid hydrogen storing and fueling station is used for filling a hydrogen storage bottle (pot) with a hydrogen fuel. The hydrogen fueling station comprises: a liquid hydrogen container used for carrying out low-pressure storage on the hydrogen fuel in a liquid form; a liquid hydrogen pump used for pressurized transportation of the low-pressure liquid hydrogen in the liquid hydrogen container toa vaporizer driving device; a vaporizer used for converting the hydrogen fuel to a gas phase from a liquid phase in order to realize the output of high-pressure hydrogen; a gas buffering bottle beinga high-pressure hydrogen buffering and temporary-storage device; a hydrogen charger used for filling the hydrogen storage bottle (pot) with hydrogen and being a special apparatus provided with a metering device; a heat exchanger and a circulating pump which are used for transmitting cold energy generated in the liquid hydrogen vaporizing process to hydrogen through a refrigerant in order to realize reduction of the hydrogen temperature; and a high-pressure liquid hydrogen charger and a low-pressure liquid hydrogen charger which are used for filling the different liquid storage bottles (pots)with high-pressure liquid hydrogen and low-pressure liquid hydrogen and are special apparatus with metering devices.

Description

technical field [0001] The invention relates to a hydrogen refueling station for filling high-pressure hydrogen or liquid hydrogen in the form of liquid hydrogen storage, which is applied in the technical field of filling hydrogen fuel for hydrogen storage bottles (tanks) such as hydrogen vehicles or hydrogen internal combustion engine vehicles. Background technique [0002] With the development of hydrogen energy application technology becoming more and more mature, and the global pressure to cope with climate change continues to increase, the development of hydrogen energy industry has attracted much attention in countries all over the world. The hydrogen refueling station is an important infrastructure for the hydrogen energy industry. The improvement of its facilities and the choice of hydrogen storage and supply routes directly affect the progress of hydrogen vehicle popularization and technology research and development. Most of the technologies used in existing hydrog...
