Solid hydrogen storage

McPhy has developed a unique patented technology for storing hydrogen in solid form (metal hydrides) at low pressure.

This technology dramatically improves security related to hydrogen storage (compared to existing technologies: high pressure> 200 bar or liquid storage at -253 C).

Fire testing of McPhy's MgH2 composite

Video: a MgH2 (Magnesium hydride) disk, which contains 600 liters of hydrogen, suffers an extreme heat (butane flame, 1900 C) during 5 minutes. There is no fire or explosion. This prove the security of our material and solid state hydrogen storage.


Innovation has created a bypass in the hydrogen supply chain, by allowing a combination of generator and low-pressure hydrogen storage (thus avoiding the intensive energy-consuming compression / liquefaction phase of hydrogen processing) to be used at point of hydrogen production or use.

McPhy offers a range of hydrides suitable for your every need.

The many benefits of solid hydrogen storage

Solid storage in containers that hold an unlimited amount of hydrogen as required (from a few tens to hundreds of kilogrammes or several tonnes) by multiplying them..

After creating small 4 kg hydrogen storage prototypes to validate its technology in 2011, McPhy will be able to provide from late 2012:

Then from early 2013, we will market MGH storage for 300 kg of hydrogen (10 MWh).
