Hydrogen compression and storage systems
| DWPI Title: Solid-state hydrogen compressor used in hydrogen compression and storage system, has storage container that is in fluid communication with inlet valve and outlet valve, and storage media arranged inside storage container, where storage media are formed from composition |
| 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. |
| Use: Solid-state hydrogen compressor used in hydrogen compression and storage system. |
| Advantage: The substituting materials is used in hydrogen compression to improve the performance of the hydrogen compression or storage system. The hydrogen compressor is designed to produce hydrogen at various output pressures by using different materials for the storage media and/or by arranging multiple compressions together in series. The output of a first stage is directed to the input of a second stage that stores hydrogen at the output pressure of the first stage and releases hydrogen at a higher second stage output pressure. The plateau pressure is increased by decreasing the hydride desorption enthalpy while increasing the hydride desorption entropy which is challenging because these properties tend to be positively correlated. |
| Novelty: The compressor (100) has a storage container (108) in fluid communication with an inlet valve (104) and an outlet valve (106). A storage media (112) is arranged inside the storage container. The storage media are formed from a composition. The composition is selected and made by providing a proposed composition for the storage media as input to a computer-implemented machine learning model, where the proposed composition comprises a first element and a second element. The computer-implemented machine learning model identifies the composition based upon properties of the first element, the second element, and the third element, where the properties comprise a ground state volume per atom of an elemental solid, a covalent radius, a Pauling electronegativity, and a number of valence electrons. |
