“…Among these three alloy samples, the alloy sample x = 0.2 had the highest hydrogen storage capacity (around 2 wt.%). This value of hydrogen storage capacity was higher than some different hydrogen storage alloy systems reported in previous studies (TiFe-based alloys [35][36][37][38], ZrCo-based alloys [21,39] and LaNi 5 -based alloys [40][41][42]). Further study, it was clear from Fig.…”

In this work, the microstructure, hydrogen storage properties, anti-oxide ability and rate limiting step of Zr(Cr 1 −x Co x ) 2 (x = 0, 0.2, 0.4 and 0.6) alloys have been investigated. After studying the crystal structure, we found that all alloy samples could show C14-type phase but the alloy sample x = 0 could also show a small amount of Cr phase. Rietveld fitting showed that lattice parameter and unit cell volume of C14-type phase decreased with increasing x. After further research, it was clear that the first hydrogen absorption capacity decreased with increasing x. But introducing more Co content had a positive influence on the effective hydrogen storage capacity and cyclic hydrogen absorption and desorption properties of the alloy sample. We also found that adding Co to ZrCr 2 alloy could improve its anti-oxide ability. In addition to this, the rate limiting step model was also studied.

“…Over-stoichiometric amounts of Ti in TiFe have been reported to improve lab-scale sample's activation performance [58]. Shang et al [59] tested the effects of adding overstoichiometric Ti (Ti 1.1 Fe) and of partial substitution of Fe for Mn (Ti 1.1 Fe 0.8 Mn 0.2 ) by melting 5 kg of material and pouring it into molds. The study showed that excess of Ti leads to reduced kinetics and capacity while substituting Fe for Mn with excess Ti leads to improved kinetics and capacity.…”

Scaling up Metal Hydrides for Real-Scale Applications: Achievements, Challenges and Outlook

As the world evolves, so does the energy demand. The storage of hydrogen using metal hydrides shows great promise due to the ability to store and deliver energy on demand while achieving higher volumetric density and safer storage conditions compared with traditional storage options such as compressed gas or liquid hydrogen. Research is typically performed on lab-sized samples and tanks and shows great potential for large scale applications. However, the effects of scale-up on the metal hydride’s performance are relatively less investigated. Studies performed so far on both materials, and hydride-based storage tanks show that the scale-up can significantly impact the system’s capacity, kinetics, and sorption properties. The findings presented in this review suggest areas of further investigation in order to implement metal hydrides in real scale applications.
