Abstract

A pressure maintaining system for a hydrogen storage system includes a hydrogen supply feed that enables a hydrogen flow from the hydrogen storage system. A liquid phase hydrogen feed enables a liquid phase hydrogen flow to the hydrogen supply feed. A gas phase hydrogen feed enables a gas phase hydrogen flow to the hydrogen supply feed. A check valve enables fluid communication from the hydrogen supply feed to the liquid phase hydrogen feed when a pressure within the hydrogen supply feed is greater than a threshold pressure.
