Why chosing to use magnesium hydride ?

The abylity of hydrogen atoms to diffuse between magnesium  crystallites and form the hybride Mgh2.

JOMI LEMAN’S(patent-protected) magnesium hydride technology establishes a fast and safe tank absorption-desorption-absorption cycle (7.000 cycle test – TLR level 7 scale).

Deployment of Hydrogen requires :

  • Reducing production costs,
  • Infrastructure construction,
  • Sustainable and secure storage and transportation solutions,

Producing green hydrogen is not technically difficultbut transport and storage it safely are challenges !

Building this ecosystem involves a significant cost…

The JOMI LEMAN solid state storage technology is the solution that will allow the massive deployment of hydrogen, at the lower cost and in a secure manner.

Producing hydrogen is not a problem!

But storing and transporting it safely and in large quantities becomes complicated, unless you use JOMI-LEMAN technology.
