Abstract
A hydrogen compressor includes an inlet valve, an outlet valve, a storage container in fluid communication with the inlet valve and the outlet valve, a heat transfer device, and storage media arranged inside the storage container. The storage media is made from an initial composition that includes a first element and a second element. The second element has at least one substitution element that is identified based on at least one of the ground state volume per atom of the elemental solid, the covalent radius, the Pauling electronegativity, and the number of valence electrons of the substitution element.

A hydrogen compressor comprising:
- an inlet valve;
- an outlet valve;
- a storage container in fluid communication with the inlet valve and the outlet valve;
- a heat transfer device;
- and
- storage media arranged inside the storage container, wherein the storage media is formed from a composition, wherein the composition is selected and made by way of a process comprising:
