This concept is essential in biological systems where organisms store energy in different forms, such as chemical bonds in macromolecules, allowing them to utilize energy when needed for various metabolic processes.

Energy Storage

Energy storage is the conversion of an energy source that is difficult to store, like electricity, into a form that allows the energy produced now to be utilized in the future. There are many different forms of energy-storage technologies that can store energy on a variety of timescales, from seconds to months.

Hydrogen Storage

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.
