    Metal hydride hydrogen storage and compression systems for energy storage technologies
    (Elsevier, 2021) Chidziva, S; Tarasov, B.P; Fursikov, P.V
    Along with a brief overview of literature data on energy storage technologies utilising hydrogen and metal hydrides, this article presents results of the related R&D activities carried out by the authors. The focus is put on proper selection of metal hydride materials on the basis of AB5- and AB2-type intermetallic compounds for hydrogen storage and compression applications, based on the analysis of PCT properties of the materials in systems with H2 gas. The article also presents features of integrated energy storage systems utilising metal hydride hydrogen storage and compression, as well as their metal hydride based components developed at IPCP and HySA Systems.

    Modelling of metal hydride hydrogen compressors from thermodynamics of hydrogen – Metal interactions viewpoint: Part I. Assessment of the performance of metal hydride materials
    (Elsevier Ltd, 2021) Lototskyy, M.V; Yartys, V.A; Tarasov, B.P
    This work presents a model to determine productivity and heat consumption of hydrogen compression utilising metal hydrides (MH) by using Pressure – Composition – Temperature (PCT) diagrams of the MH materials at defined operating conditions – temperatures and hydrogen pressures. The present Part I is focused on the analysis of hydrogen compression performances of several AB5- and AB2-type intermetallic alloys which, when operating between temperatures of 20 and 150 °C, provide H2 compression up to 500 atm, with a cycle productivity about 100 NL H2/kg MH and compression ratio of up to 10, at H2 suction pressure below 10–15 atm, or up to 5 at higher suction pressures. We show that calculated cycle productivities of hydrogen compression are related to the operating conditions and significantly vary for the different MH materials, even though showing similar trends in their changes.
