Metal hydride tank is a container loading with hydrogen storage alloy powder, heat exchange parts, and gas transport components. The container body materials are generally aluminum alloy or stainless steel. Our hydrogen storage vessels are based on AB5 metal hydride alloys. Hydrogen being stored at low pressure in the vessel, they provide a safe and reliable energy storage, particularly for portable applications, in-house and in-board storage.

Individual vessels can be combined in arrays to reach specific H2 volumes and discharge rates. Contact us for custom-built hydrogen storage. Chose your storage depending on the quantity of hydrogen you wish to store. The number in the product name refers to the quantity of normal liters of gas kept in the vessel (for instance, the TH150 tank can store up to 150NL of hydrogen). Typical uses of the tanks include fuel cell power, gas chromatography and lab experiments/chemical reactions.

The performance of a metal hydride tank mainly includes the following aspects:
. Capacity — how much hydrogen can be stored, generally indicated as in standard liters NL;
. Releasing rate — the rate that hydrogen is released from the tank. A sufficient heat supply is required for hydrogen releasing. The rate is determined by the type of metal hydride, efficiency of heat exchange as well as gas transport resistance;

. Recharging time — time that used to refueling the tank;
. Cycle life — the cycle number that the tank can be refueled without a significant degradation in capacity.

The main features of the metal hydride tank:

. High storage density；
. Capability of low temperature releasing
. Quick locking;
. Flexibility in tank size;
. Body materials: stainless steel or aluminum alloy

How to charge your metal hydride tanks

Metal hydride tanks can be filled with hydrogen when connected to a pressurized H2 source or water electrolysis system, for instance an industrial H2 bottle obtained from your local gas supplier. Typical input pressure required to charge the tanks varies between 10 to 20 barg depending on the size of the vessel. Lower pressure can be used but charging time is then increase. Contact us to obtain the charging conditions graphs.

Because of the exothermal reaction when charging the vessels, they must be cooled down during the filling process. Small and medium size tanks can simply be put into cold/fresh water (in a glass or any other type of reservoir). Large tanks can be equipped with a cooling circuit.

Charging time is very short compared to the time required to charge a conventional battery.

For instance, the small 10 or 20's are fully charged in less than 20 minutes.

Multiple tanks can be charged simultaneously from a single hydrogen source.

Secure Supplies Industries provides accessories like charging sets,

connecting devices and can put you in touch with your local gas supplier.

Using good quality hydrogen, with a purity at least equal to 99.99%, ensures a long lasting use of the vessels.

Safety

Metal hydride tanks are ideal for indoor use thanks to their low storage pressure.
However the user should consider the volume of the room where the vessel is stored compared to the volume of hydrogen stored. Hydrogen has a Lower Flammable Limit (LFL) of 4% diluted in air. We recommend that the uncompressed total volume of hydrogen stored does not exceed 2% (half of the LFL) of the total volume of the room.

Our tanks are delivered filled with argon to comply with air transportation security rules.

Therefore, they need to be charged before being usable.

How does metal hydride tanks work ?

Storage Mechanism
Hydrogen is stored in the form of so-called “metal hydride”.
Most metals or alloys can react with hydrogen to form new compounds, which are named as metal hydrides. The formation of metal hydride is an exothermic process associated with heat releasing. With sufficient heat supply, hydrogen can be released from the as-formed metal hydride. Such a reversible reaction process can be expressed as follows:

2/nM + H2 = 2/nMHn +ΔH

where M-metal or alloy; MHn-metal hydride; ΔH-thermal effect associated with the reaction. Pressure and temperature changed, the reaction will take place alternatively and hydrogen will be absorbed or desorbed.

Specifications

High safety metal hydride H2 storage tankThis product can absorb and desorb hydrogen at the room temperature .

High safety metal hydride container

This product can absorb and desorb hydrogen at the room temperature and relatively low pressure, and more than 90% quantity of the hydrogen stored in it can be desorbed at relatively steady pressure in very steady hydrogen gas current. The hydrogen absorbing and desorbing pressure and the desorbing flow of the product depend on the users’ demand. Through the use of the product, the ordinary hydrogen can be purified into the ultra high pure hydrogen of 5 N purity, which indicates that the technology of the product has reached the international advanced level. The specifications of the product are defined with the amount of the desorbing hydrogen in standard state, which is from several liters to several hundreds of cubic meters. The shape of the product is generally cylindrical, and it can be adjusted with the users’ demand.
