A recently granted patent (Publication Number: US11866836B2) describes a distributed hydrogen generating fence that includes a series of electrolysis units, each equipped with photovoltaic cells to power an electrolysis system producing hydrogen and oxygen gas. The fence structure incorporates fence posts supporting the electrolysis units and a gas header to transport the hydrogen gas to a remote facility. Additionally, the fence design allows for the inclusion of batteries in some units to store excess electricity generated by the PV cells for use in the electrolysis process, ensuring continuous hydrogen production.

Furthermore, the patent details the integration of safety features such as vents for oxygen gas release, openings in the fence for passage of animals or vehicles, and electrified strands or mesh to protect the units from damage. The flexible placement of PV cells on the fence structure, along with the use of knock out drums for efficient water and electrolyte flow between electrolysis units, enhances the overall functionality and effectiveness of the distributed hydrogen generating fence. These innovative features highlight the potential for sustainable hydrogen production through a unique and versatile infrastructure design.
