“…Recently, a lab scale system consisting of a three stage MHHC was demonstrated at the Universitad Autónoma de Madrid. It is based on AB 2 materials used to compress the H 2 produced by a photo-electrolyser, with a typical output of less than 1 bar, up to 120 bar when the third stage is heated to 120 • C [76]. For this application, TiMn 2 type alloys were selected for all stages.…”

Recently, the industrial and public interest in hydrogen technologies has strongly risen, since hydrogen is the ideal means for medium to long term energy storage, transport and usage in combination with renewable and green energy supply. Therefore, in a future energy system the production, storage and usage of green hydrogen is a key technology. Hydrogen is and will in future be even more used for industrial production processes as reduction agent or for the production of synthetic hydrocarbons, especially in the chemical industry and refineries. Under certain conditions material based systems for hydrogen storage and compression offer advantages over the classical systems based on gaseous or liquid hydrogen. This includes in particular lower maintenance costs, higher reliability and safety. Hydrogen storage is possible at pressures and temperatures much closer to ambient conditions. Hydrogen compression is possible without any moving parts and only by using waste heat. In this paper, the newest developments of hydrogen carriers for storage and compression are summarized. In addition, an overview of the different research activities in this field are given.

“…According to our modelling results, 51 the application of C14-(Ti,Zr)(Cr,Fe,Ni,Mn,V) 2 alloys with different for the different stages and carefully adjusted contents of the components allows to achieve productivity of H 2 compression from 30 to 500 bar (compression ratio of 16.7 at T = 20-150 C) up to 5 Nm 3 in two stages only, when using reasonable amounts (15-20 kg per a stage) of the MH materials. Recently reported results of experimental tests of a prototype MHHC also based on multicomponent AB 2 -type hydride-forming alloys of different compositions 33 showed a possibility to achieve H 2 compression ratio of 84.7 (1.44-122 bar at T = 23-120 C) in three stages.…”

Summary Hydrogen compression is a major contributor to capital costs and maintenance hours in the infrastructure related to storage, distribution and end‐use of hydrogen. Conventionally used mechanical hydrogen compressors have a number of disadvantages including a complicated design, insufficient reliability, high operating costs, a probability of hydrogen leakage and hydrogen contamination. A promising alternative is a thermally driven metal hydride hydrogen compressor (MHHC) whose operation is based on the reversible interaction of hydride‐forming alloys with hydrogen gas. MHHCs have a number of advantages including practically unlimited (up to several kbars) discharge pressure, good scalability (from several normal litres to tens normal cubic metres of hydrogen per an hour), modular design, simplicity in service and operation, as well as high purity of the delivered hydrogen and a possibility to use low‐grade heat. MHHC does not contain moving parts that simplifies its design, increases reliability, and eliminates noise and vibration. This article overviews applied R&D activities related to the thermally driven hydrogen compression using metal hydrides. The focus is put on the interrelation between properties of metal hydride materials and their hydrogen compression performances, first of all, operating pressure ‐ temperature range, process productivity, and efficiency. Typical design features of the hydrogen compression systems and ways of their optimization are considered. A brief techno‐economic analysis of the MHHCs benchmarked against alternative hydrogen compression technologies (mechanical and electrochemical) is presented as well. Finally, promising application niches of the MHHCs are outlined.

“…By comparison, AB 2 -type Ti-based Laves phase alloys exhibit a high hydrogen pressure, along with excellent hydrogen plateau characteristics and high hydrogen capacity . MHHCs employing AB 2 -type alloys are hence able to achieve hydrogen compression to much higher pressures at relatively lower temperatures. − For example, Corgnale et al reported on a Ti 1.1 CrMn alloy for a hybrid MHHC with a hydrogen compression performance of 45 MPa at 413 K. Smith et al proposed a MHHC that employs a Ti 0.8 Zr 0.2 Fe 1.6 V 0.4 alloy and realizes a hydrogen compression of up to 80 MPa at around 433 K. According to the reports, it is noticeable that a high operation temperature and suitable organic fluid media for heat transfer are generally adopted on MHHCs employing V-based solid solutions or AB 5 -type alloys, in order to compress the hydrogen with a pressure much higher than their usual performance at moderate temperature. This is basically attributed to the relatively low hydrogen ab-/desorption pressure of these alloys.…”

Three series of alloys, Ti 0.92 Zr 0.10 Cr 1.7−x Mn 0.3 Fe x (x = 0.2−0.4), Ti 0.92 Zr 0.10 Cr 1.6−y Mn y Fe 0.4 (y = 0.1−0.7), and Ti 0.92+z Zr 0.10−z Cr 1.3 Mn 0.3 Fe 0.4 (z = 0, 0.015, 0.04), were prepared by induction levitation melting for a metal hydride hydrogen compressor from 8 to 20 MPa at water-bath temperature, with investigation on their crystal structural characteristics and hydrogen storage properties. The results show that a single C14-Laves phase with homogeneous element distribution exists in all of the alloys. The hydrogen ab-/ desorption plateau of the alloys is increased as the Fe, Mn, or Ti content increases due to decrement of the interstitial site radius originated from the respective atomic size. The hydrogen storage capacity of the alloys also correlates negatively with the hydrogen affinity of interstitial sites due to the influence of the element electronegativity. In a comprehensive consideration of the hydrogen storage performance for application, the Ti 0.935 Zr 0.085 Cr 1.3 Mn 0.3 Fe 0.4 alloy shows saturated hydrogenation under 8 MPa at 293 K and dehydrogenation around 24.91 MPa pressure at 363 K with a hydrogen capacity of 1.74 wt %, as well as excellent cycling performance and mere hysteresis. The Ti 0.92 Zr 0.10 Cr 1.0 Mn 0.6 Fe 0.4 alloy is another promising candidate with a remarkable hydrogen capacity of 1.86 wt % at 283 K and a dehydrogenation pressure of 27.94 MPa at 363 K, together with a satisfactory cycling durability. This study can guide the compositional design of AB 2 -type hydrogen storage alloys for hydrogen compression application.
