Abstract:
Aiming at the application requirements of hydrogen fuel in power systems,the research mainly focused on two sides:hydrogen storage and pressurization transport,including that the research status was reviewed,the principle of hydrogen storage was introduced,the storage and transportation scheme was summarized,the advantages and disadvantages were compared,and the strategy for enhancing system security hydrogen was valid,further,the zero boil-off storage schemes were compared. According to the system requirements and technology guide line for zero boil-off storage of hydrogen,the liquid hydrogen(LH2)storage tank was designed,related techniques were indicated below:firstly,the shape designing of a storage tank,the selection of thermal insulation structure,the demonstration of schemes for support structure,the designing of sloshing suppression for LH2storage tank,and analysis of the design of strength;in addition,the heat transfer and strength of LH2storage tanks were numerical calculated using CFD modules to evaluate the insulation effect of cryogenic insulation structures and analyzed the stress-strain of loaded LH2storage tanks to strength calculation in cryogenic conditions;Finally,the test verified that the designed LH2storage tank can meet the design requirements of zero boil-off storage that the value of heat flux was less than 1.4 W/m2. The results provided a theoretical basis and guidance for designing,developing,numerical simulation,and applying LH2storage tanks in China.
