How many tons of hydrogen can be stored

How can hydrogen be stored?

Hydrogen can be stored physically as either a gas or a liquid. Storage as a gas requires high-pressure tanks (350–700 bar), while storage as a liquid requires cryogenic temperatures due to hydrogen's boiling point of −252.8°C at one atmosphere pressure.

What is safe hydrogen storage?

Safe hydrogen storage is a key enabler for the advancement of hydrogen and fuel cell technologies. Hydrogen storage tanks. Hydrogen can be physically stored as a compressed gas or cryogenic liquid. Compressed gaseous hydrogen is typically held in tanks at 350-700 bar (5,000-10,000 psi).

How much hydrogen can be stored in a vehicle?

A volume of 11.2 Nm³ (the volume of the boot of a large utility or commercial vehicle) is needed to store just 1 kg of hydrogen, which is the amount required to travel approximately 100 km. Thus, for hydrogen storage to be economically viable, its storage density must be increased.

What is hydrogen storage based on?

Hydrogen storage can be divided according to whether it is based on physical or material storage (see Figure 1). Under physical storage, it is stored as a gas or liquid as a pure molecular compound with no significant physical or chemical bonding to other materials.

What is the cost of a hydrogen storage system?

Specific system targets include the following: $10/kWh ($333/kg stored hydrogen capacity). The collaborative Hydrogen Storage Engineering Center of Excellence conducts analysis activities to determine the current status of materials-based storage system technologies.

Can liquid hydrogen be stored in isolated pressure vessels?

The storage of liquid hydrogen in isolated pressure vessels overcomes many of the weaknesses of CH₂ or LH₂ tanks and may even unlock new opportunities. However, this storage technology is not yet fully developed nowadays.
