Hydride compressor
A hydride compressor is a hydrogen compressor based on metal hydrides with absorption of hydrogen at low pressure and desorption of hydrogen at high pressure by raising the temperature with an external heat source like a heated waterbed or electric coil.[1][2][3][4]
Advantages of the hydride compressor are the high volumetric density, no moving parts and reversible absorption/desorption, disadvantages are the high cost of the metal hydride and weight.
History
The first applications of metal hydrides were made by NASA to demonstrate long-term hydrogen storage for use in space propulsion. In the 1970s, automobiles, vans, and forklifts were demonstrated.[5] The metal hydrides were used for hydrogen storage, separation, and refrigeration. An example of current use are hydrogen sorption cryocoolers[6] and portable metal hydride compressors.[7]
