HBank Hydrogen Storage

AB5-type alloy

Using special vacuum technology from rare-earth and transition metals can be melted alloys, which are able to absorb hydrogen from the gas phase. These alloys, at room temperature and under certain hydrogen pressure, are absorbing extremely large quantities of hydrogen by forming solid metal hydrides. The chemical reaction of hydride formation is accompanied with release of heat into environment. The hydrogen absorption process can be reversed if the hydrogen pressure is lowered below some certain value.In this case, desorption of hydrogen gas is accompanied with heat absorption from environment.

The hydrogen storage alloys, based on rare-earth metals, Ti, Zr, Fe, et. al, are extensively studied. However, only rare-earth based so called AB5-type and transition metal based AB2-type alloys has reached the stage of mass production and commercialization. At the same time, as a reversible gas storage material, only AB5-type alloys can operate at moderate temperatures (from -20°C up to +60°C), while the AB2-type ones require additional heating.

Developed by H Bank in 2000, the patented alloy compositions are able to absorb hydrogen as high as 1.65wt.%, whereas the maximum values for commercial AB5-type alloy is below 1.5wt.% so far. The alloy outperforms any existing AB5-type alloy.

In 2004, H Bank devoted in putting the solid state hydrogen storage idea into the market. H Bank has developed a big variety of hydrogen storage tanks and containers with amount of stored hydrogen from 10 up to 100,000 litters. All H Bank's rights on these products are protected with corresponding patents. H Bank will devote every effort to replace dangerous high-pressure hydrogen cylinders with safe metal-hydride based storages.
