Hydrogen Storage System and Use of Such a Hydrogen Storage System for Catalytic Hydrogenation and/or Catalytic Dehydrogenation

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

This patent describes a hydrogen storage system that uses organic compounds containing only carbon, hydrogen, and oxygen. These compounds can reversibly switch between a hydrogen-poor and a hydrogen-rich form through catalytic hydrogenation (adding hydrogen) or dehydrogenation (removing hydrogen). The molecules are designed with specific structural features in their hydrogen-poor and hydrogen-rich states to facilitate efficient hydrogen storage and release.

Patent Abstract

A hydrogen storage system comprises at least one compound that is reversibly convertible from a hydrogen-poor form to a hydrogen-rich form by catalytic hydrogenation or conversely by catalytic dehydrogenation, wherein the compound contains exclusively the elements carbon, hydrogen and oxygen. The compound has in the hydrogen-poor form at least two non-condensed aromatic units and at least one carbonyl group on a carbon atom outside the aromatic units and/or in the hydrogen-rich form at least two cycloalkyl groups and at least one secondary alcohol function linked to a carbon atom outside the cycloalkyl groups.
