The United States Patent and Trademark Office (USPTO) has granted patent US12586826B2 to EnerVenue Holdings, Ltd. for a novel method of operating metal-hydrogen batteries. This patent covers a process that involves monitoring indicators of battery degeneration during normal charge and discharge cycles, specifically identifying decay caused by oxidation, and subsequently regenerating the battery to restore its performance. The patent was officially granted on March 24, 2026.

This patent grant signifies a new technological development in battery operation and maintenance. While not a regulatory rule imposing direct compliance obligations on other entities, it represents an advancement in the field of energy storage. Companies involved in the manufacturing or utilization of metal-hydrogen batteries, particularly those experiencing issues with oxidation-induced degradation, may find this patented method relevant for potential licensing or as a benchmark for their own research and development efforts.
