= 0, 0.02, 0.05, and 0.08) alloys were prepared through induction levitation melting, and their crystal structure characteristics and hydrogen storage properties were investigated by experiments and first-principles calculations. The alloys exhibit a main C14-Laves phase with fine element homogeneity and minor oxides. As the Nb stoichiometry in Ti 1.02 Nb x Cr 1.0−x Mn 0.6 Fe 0.4 (x = 0−0.05) alloys increases, the alloy exhibits enhanced hydrogen absorption/desorption kinetics and capacity, despite an increased plateau slope due to improved hydrogen affinity. The Ti 1.02−y Nb y Cr 1.0 Mn 0.6 Fe 0.4 (y = 0−0.08) alloys show simultaneous hysteresis amelioration and plateau pressure increment as the Nb content increases, thanks to hydride destabilization and expanded interstitials. The effects can be attributed to the medium atomic size and hydrogen affinity of Nb. Moreover, the first-principles calculation results indicate preferential occupancy at 4f sites of Nb in Ti−Cr−Mn−Fe-based alloys, and an expanded crystal lattice can be achieved with Nb substitution for Cr or Ti. This work shows that Nb substitution can be a promising strategy for the hydrogen storage performance enhancement of Ti−Cr-based Laves phase alloys for hydrogen compression applications.

Machine learning (ML) has emerged as a pioneering tool in advancing the research application of high‐performance solid‐state hydrogen storage materials (HSMs). This review summarizes the state‐of‐the‐art research of ML in resolving crucial issues such as low hydrogen storage capacity and unfavorable de‐/hydrogenation cycling conditions. First, the datasets, feature descriptors, and prevalent ML models tailored for HSMs are described. Specific examples include the successful application of ML in titanium‐based, rare‐earth‐based, solid solution, magnesium‐based, and complex HSMs, showcasing its role in exploiting composition–structure–property relationships and designing novel HSMs for specific applications. One of the representative ML works is the single‐phase Ti‐based HSM with superior cost‐effective and comprehensive properties, tailored to fuel cell hydrogen feeding system at ambient temperature and pressure through high‐throughput composition‐performance scanning. More importantly, this review also identifies and critically analyzes the key challenges faced by ML in this domain, including poor data quality and availability, and the balance between model interpretability and accuracy, together with feasible countermeasures suggested to ameliorate these problems. In summary, this work outlines a roadmap for enhancing ML's utilization in solid‐state hydrogen storage research, promoting more efficient and sustainable energy storage solutions.
