A study on 70MPa metal hydride hydrogen compressor

Evaluation of a thermally-driven metal-hydride-based hydrogen compressor

“…The design was based on previous hydride-based compressors built by Wang and co-workers [15,16,18]. We specified the compression ratio (about three), the design initial and final pressures, and the goal of compressing about 125 g of hydrogen per hour.…”

“…The hydride compressors were built in China based on the design of Wang and co-workers [15,16,18]. They consist of cylindrical stainless steel tubes filled with a powdered misch metal and contained within a rectangular box filled with oil.…”

“…Wang and coworkers [16,17] discuss testing a range of such alloys for a compressor in order to optimize the properties of the alloy with respect to the thermodynamics, kinetics, and durability for use in a compressor. The relationship between the compressor characteristics and the alloy pressure plateau, kinetics, reaction enthalpy (DH), and percentage hydrogen storage for the best alloy is discussed elsewhere by Wang and co-workers [15,16,18]. In addition to the alloy, the 16 cylindrical tubes contained aluminum for better heat transfer.…”

Numerical study on a two-stage Metal Hydride Hydrogen Compression system

“…A multistage Metal Hydride Hydrogen Compression (MHHC) system uses a combination of different metal hydrides to increase the final compression ratio while maximizing the hydrogenation process from both the supply pressure of each stage. Over the last decade a large number of scientists have made efforts in the subject of MHHC systems and some promising results regarding the material selection and the compression conditions were found both experimentally [3][4][5][6][7][8][9] and numerically [10][11][12][13]. In most cases, three combinations of materials are selected for a two-stage compression system.…”

Experimental study on full-scale ZrCo and depleted uranium beds applied for fast recovery and delivery of hydrogen isotopes

“…Using high-pressure metal hydride bed is of great interest for high efficient hydrogen compression. La-Ce-Ca-Ni-Al family AB 5 type and Ti-Zr-Cr-Fe-V family AB 2 type multicomponent alloys have been chosen to develop high pressure hydrogen compression metal hydride bed [30,31].…”
