Abstract
The present disclosure discloses a system for renewable hydrogen generation and storage. The system comprises at least one solar photovoltaic (PV) panel; an atmospheric water generator configured to extract water from a humid atmosphere; a water electrolyzer configured receive the water extracted by the atmospheric water generator and configured to produce hydrogen and oxygen from the water using electrolysis; and a metal hydride storage tank for storing the hydrogen produced by the water electrolyzer. Waste heat generated by the atmospheric water generator is used for thermal management of the metal hydride storage tank. A method for producing and storing hydrogen is also provided.

A system for renewable hydrogen generation and storage, the system comprising:
- at least one solar photovoltaic (PV) panel;
- an atmospheric water generator electrically powered by electricity generated by the at least one solar PV panel, the atmospheric water generator configured to extract water from a humid atmosphere;
- a water electrolyzer electrically powered by electricity generated by the at least one solar PV panel, the water electrolyzer configured to receive the water extracted by the atmospheric water generator, and configured to produce hydrogen and oxygen from the water using electrolysis;
- and
- a metal hydride storage tank for storing the hydrogen produced by the water electrolyzer;
- wherein, waste heat generated by the atmospheric water generator is used for thermal management of the metal hydride storage tank, wherein the system is configured to heat the metal hydride storage tank using the waste heat when the metal hydride storage tank is in a discharging configuration, whereby hydrogen is being discharged from the metal hydride storage tank.
