Optimization of a Mixed Refrigerant Based H2 Liquefaction Pre-Cooling Process and Estimate of Liquefaction Performance with Varying Ambient Temperature

Hydrogen used as an energy carrier can provide important route to the decarbonization of supplies, but realizing this opportunity will require both significantly increased production and transportation capacity. One capacity is shipping liquid hydrogen, requires energy-intensive liquefaction step. Recent study work has shown that required in process be reduced through implementation new improved designs, since all low-temperature processes are affected by available heat-sink temperature, local ambient conditions also have impact. The objective identify how consumption associated with hydrogen varies temperature optimization design parameters for a next-generation mixed refrigerant based process. results show increases around 20% across cooling range 5 50 °C. Considering just 20 30 °C, there 5% increase, illustrating significant impact on consumption. implications modelling different liquified supply chains should take into account.
