Improving the hydrogen storage density of polymer-based hydrogen storage materials is a key challenge in developing efficient hydrogen storage systems for applications like fuel cells and clean energy. There are several strategies to enhance the hydrogen storage capacity, both in terms of gravimetric (weight-based) and volumetric (space-based) density. These strategies focus on enhancing the ability of the polymer to absorb, retain, and release hydrogen effectively.
Polymers exhibit different characteristics under different conditions. Of course, we cannot speak about such systems for everyday use of hydrogen at all.
