Solid State Hydrogen Storage

Solid State Hydrogen Storage

 

Hydrogen can be stored within a metal hydride; these are metallic compounds that adsorb hydrogen into their structure; it is even possible to store hydrogen more efficiently than liquid hydrogen. Some of the advantages and disadvantages are noted below:

Potential Advantages
Low pressures involved
Release of extremely pure hydrogen
Storage units can be cycled thousands of times with minimal loss in storage capacity
Simple to increase capacity by manifolding multiple units together

Potential Disadvantages
Metal hydrides can be susceptible to poising by impurities  when recharging
Kinetics can be slow, resulting in a slow release / absorption rate of hydrogen
Metal hydrides often have a high weight penalty attached
Metal hydrides need to be thermally managed to maximise  performance

Typical metal hydrides will supply high purity, gaseous hydrogen at modest pressure and temperatures. Hydrogen is released from hydrogen stored within metal hydrides if the pressure in the container, storing the metal hydride falls below what is known as the” plateau pressure”, and absorb hydrogen if the pressure rises above the plateau. The plateau pressure can be altered by either changing the material specification (alloy composition) or by heating/cooling the metal hydride.

We have collectively 10+ years experience at developing and integrating Solid State hydrogen storage solutions into a wide range of mobile and static applications.
