How Hydrogen Storage Works. 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 − ...
The battery energy storage system''s (BESS) essential function is to capture the energy from different sources and store it in rechargeable batteries for later use.

The energy performance of a storage can hence be described by means of two main parameters: the energy storage capacity and the thermal efficiency of the storage. The energy storage capacity of the system (ESCsys) measures the total amount of heat that can be stored by the system. This heat is mainly stored in the TES material.
