As expected, Table shows the effect and importance of the relationship between the operating parameters of a metal hydride compressor. Alloy combinations must be chosen to match thermodynamics at the desired operating temperatures to maximize hydrogen flow rate and energy efficiency. For accurate predictions this must be done using realistic representations of the PCTs for each hydride that account for plateau slope and hysteresis at relevant pressures and temperatures. The study shows that tradeoffs must be made between compression ratio and energy efficiency with a larger pressure range requiring higher energy use. At some compression ratio, the number of stages must increase assuming a fixed or limited temperature range. This not only reduces energy efficiency as more heat must be used for the additional stage (sensible heating and desorption enthalpy) but also increases the capital cost of the compressor which was not considered in this study. With these effects accounted for, the study shows that the TCMCFL material enables delivery of 875 bar hydrogen at the desired flow rate over reasonable operating temperature range in either a 2-stage or 3-stage compressor configuration, depending on the source pressure.
