Abstract
An apparatus may comprise a solid-phase hydrogen supply system configured to generate, based on a chemical reaction of a chemical hydride, hydrogen gas in a first pressure range, a compression system configured to selectively change a pressure of the hydrogen gas generated by the solid-phase hydrogen supply system to a second pressure range that extends beyond the first pressure range, and a dispenser configured to provide hydrogen gas to a charging target from at least one of the solid-phase hydrogen supply system or the compression system.
Claims20
An apparatus comprising:
- a solid-phase hydrogen supply system configured to generate, based on a chemical reaction of a chemical hydride, hydrogen gas in a first pressure range;
- a compression system configured to selectively change a pressure of the hydrogen gas generated by the solid-phase hydrogen supply system to a second pressure range that extends beyond the first pressure range;
- and
- a dispenser configured to provide hydrogen gas to a charging target from at least one of the solid-phase hydrogen supply system or the compression system.
A method performed by an apparatus comprising a compression system and a solid-phase hydrogen supply system, the method comprising:
- determining, based on an internal pressure of a dehydrogenation reactor of the solid-phase hydrogen supply system or an internal pressure of a buffer tank of the solid-phase hydrogen supply system, whether the dehydrogenation reactor is performing a dehydrogenation reaction to generate hydrogen gas;
- determining, based on an internal pressure of a hydrogen tank of the compression system, whether a booster pump of the compression system and a hydrogen compressor of the compression system are compressing hydrogen gas from the buffer tank into the hydrogen tank;
- and
- supplying, based on a required charging pressure associated with a charging target, hydrogen gas to the charging target by:
- supplying hydrogen gas stored in the hydrogen tank of the compression system to the charging target, or
- supplying hydrogen gas stored in the buffer tank of the solid-phase hydrogen supply system to the charging target.
An apparatus comprising:
- a solid-phase hydrogen generation system configured to produce hydrogen gas via a reaction between a solid-phase hydrogen storage material and a reactive liquid;
- a storage vessel configured to receive and store the hydrogen gas generated by the solid-phase hydrogen generation system;
- a compressor configured to increase a pressure of the hydrogen gas from the storage vessel;
- a tank configured to store the hydrogen gas compressed by the compressor;
- and
- a dispenser configured to supply hydrogen gas to a hydrogen-receiving device from at least one of the storage vessel or the tank.
