【Abstract】 Based on the special demand for cryogenic insulation for efficient storage, transportation, and utilization of liquid hydrogen, the application conditions, conversion rates, and application methods of parahydrogen to orthohydrogen conversion were summarized in various application scenarios. According to the presence or absence of a catalyst, the application conditions and conversion rates of the self-conversion process and the catalytic conversion process were summarized, as well as the common catalyst types. According to the temperature range of hydrogen energy storage, the parahydrogen to orthohydrogen conversion and cooling process in three storage schemes, namely liquid hydrogen, low-temperature compressed hydrogen, and adsorption hydrogen storage, were summarized and analyzed. The advances in parahydrogen to orthohydrogen conversion were reviewed from the aspects of the structure of the converter, the measurement method of components, and the amount of cooling capacity. In addition, the contribution rate of the cooling capacity of the conversion to prolonging the duration of hydrogen energy storage was analyzed.更多还原
