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.

Battery vs. Fuel Cell

Batteries and fuel cells are both energy storage devices, but they operate on different principles. Batteries store energy chemically and convert it into electrical energy through a chemical reaction. They are rechargeable and commonly used in portable electronic devices. On the other hand, fuel cells generate electricity through an

Essentially it takes the chemical energy that is stored within whatever energy source you have such as hydrogen, gasoline or methane and then through two electrochemical reactions it converts it directly to electricity.

Energy storage

The most popular technique is ice storage, which requires less space than water and is cheaper than fuel cells or flywheels. In this application, a standard chiller runs at night to produce an ice pile. Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours
