Cryogenic containment system

A system, comprising:

• a storage tank configured to store cryogenic hydrogen in a two-phase mixture;
• a liquefaction system configured to receive input hydrogen from an external source and provide the cryogenic hydrogen to the storage tank in a liquid phase;
• a backup power system configured to receive cryogenic hydrogen in the liquid phase or in a gaseous phase, wherein the backup power system is configured to be activated when:
• a primary power system fails to meet a power demand;
• or
• a boil-off controller determines that a storage pressure of cryogenic hydrogen stored in the storage tank satisfies a pressure threshold associated with the storage tank;
• and
• an economizer valve configured to direct the cryogenic hydrogen from the storage tank and provided to the backup power system, wherein when the backup power system is activated:
• the economizer valve is configured to be switched to a first state when a storage pressure within the storage tank is at or exceeds a pressure threshold, wherein the first state of the economizer valve causes the cryogenic hydrogen to be provided to the backup power system in the gaseous phase, and
• the economizer valve is configured to be switched to a second state when a storage pressure within the storage tank is below the pressure threshold, wherein the second state of the economizer valve causes the cryogenic hydrogen to be provided to the backup power system in the liquid phase,
• the boil-off controller being configured to:
• determine whether the storage pressure of the cryogenic hydrogen satisfies the pressure threshold associated with the storage tank,
• based on determining that the storage pressure satisfies the maximum pressure threshold, activate the backup power system such that the backup power system consumes boil-off hydrogen received through the boil-off valve,
• open a boil-off valve to cause the cryogenic hydrogen in the gaseous phase to be obtained from the storage tank through the boil-off valve if the storage pressure is at or exceeds the second pressure threshold, and
• cause the cryogenic hydrogen in the gaseous phase to be directed to the backup power system.
