Hydrogen energy and ordinary batteries
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
