Hydrogen compressor based on absorption and desorption of hydrogen
A hydride compressor is a hydrogen compressor based on metal hydrides with absorption of hydrogen at low pressure, releasing heat, and desorption of hydrogen at high pressure, absorbing heat, 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, simplicity in design and operation, the possibility to consume waste heat instead of electricity[5] and reversible absorption/desorption, disadvantages are the high cost of the metal hydride and weight.
