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.
Claims20
A pressure maintaining system for a hydrogen storage system, comprising:
- a hydrogen supply feed that enables a hydrogen flow from said hydrogen storage system;
- a liquid phase hydrogen feed that enables a liquid phase hydrogen flow to said hydrogen supply feed;
- a gas phase hydrogen feed that enables a gas phase hydrogen flow to said hydrogen supply feed;
- and
- a check valve that enables fluid communication from said hydrogen supply feed over said liquid phase hydrogen feed into said hydrogen storage system when a pressure within said hydrogen supply feed is greater than a threshold pressure.
A hydrogen storage system that stores liquid phase hydrogen and gas phase hydrogen within a two-phase diagram of liquefied hydrogen or high-density hydrogen fluid outside of a two-phase boundary, comprising:
- a storage vessel;
- and
- a pressure maintaining system that regulates a hydrogen flow from said storage vessel and that comprises:
- a hydrogen supply feed that enables said hydrogen flow;
- a liquid phase hydrogen feed that enables a liquid phase hydrogen flow to said hydrogen supply feed;
- a gas phase hydrogen feed that enables a gas phase hydrogen flow to said hydrogen supply feed;
- and
- a check valve that enables fluid communication from said hydrogen supply feed to said liquid phase hydrogen feed when a supply pressure within said hydrogen supply feed is greater than a threshold pressure.
