| description | Metal hydride (MH) hydrogen storage and compression systems with near-atmospheric H<sub>2</sub> suction pressure are necessary for the utilization of the low-pressure H<sub>2</sub> produced by solid oxide electrolyzers or released as a byproduct of chemical industries. Such systems should provide reasonably high productivity in the modes of both charge (H<sub>2</sub> absorption at P<sub>L</sub> ≤ 1 atm) and discharge (H<sub>2</sub> desorption at P<sub>H</sub> = 2–5 atm), which implies the provision of H<sub>2</sub> equilibrium pressures Peq < P<sub>L</sub> at the available cooling temperature (T<sub>L</sub> = 15–20 °C) and, at the same time, Peq > P<sub>H</sub> when heated to T<sub>H</sub> = 90–150 °C. This work presents results of the development of such systems based on AB<sub>5</sub>-type intermetallics characterized by Peq of 0.1–0.3 atm and 3–8 atm for H<sub>2</sub> absorption at T<sub>L</sub> = 15 °C and H<sub>2</sub> desorption at T<sub>H</sub> = 100 °C, respectively. The MH powders mixed with 1 wt.% of Ni-doped graphene-like material or expanded natural graphite for the improvement of H<sub>2</sub> charge dynamics were loaded in a cylindrical container equipped with internal and external heat exchangers. The developed units with a capacity of about 1 Nm<sup>3</sup> H<sub>2</sub> were shown to exhibit H<sub>2</sub> flow rates above 10 NL/min during H<sub>2</sub> charge at ≤1 atm when cooled to ≤20 °C with cold water and H<sub>2</sub> release at a pressure above 2 and 5 atm when heated to 90 and 120 °C with hot water and steam, respectively. |
