Method for Producing a Hydrogen Storage Material and Hydrogen Storage Material

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a new method for producing hydrogen storage materials using metal hydrides or complex metal hydrides mixed with an organic carrier liquid, then ground to form a fine suspension. By optimizing the ratio of the solid to liquid and grinding parameters, the resulting particles are much smaller and have higher surface area than previous methods. This new suspension leads to materials that can store more hydrogen and allow for quicker absorption and liberation of hydrogen, while also being easy to handle and transport.

Patent Abstract

The invention relates to a method for producing a storage material for hydrogen, wherein a metal hydride or a complex metal hydride, optionally as an element of an alloy, is mixed with an organic carrier liquid and the mixture is then ground. According to the invention, the mixing ratio of the metal hydride, the complex metal hydride or the alloy to the carrier liquid and the grinding parameters are selected in such a manner that a suspension of the metal hydride, of the complex metal hydride or of the alloy is formed in the carrier liquid after grinding, resulting in the agglomeration of the grains to give smaller particles when the suspension dries than according to prior art method according to which a slurry is formed after grinding. Both the storage capacity for hydrogen and the speed of incorporation and removal of hydrogen are advantageously increased according to the invention. The suspension has a good storability and pumpability. The invention also relates to a storage material for hydrogen having specific properties which storage material can be produced according to the method of the invention.
