Abstract Scope |
The demand for efficient and sustainable hydrogen storage materials is growing as hydrogen becomes a key player in clean energy technologies. Hence, this review explores the effect of magnesium hydride (MgH₂) on the hydrogen storage capabilities of high entropy alloys (HEAs) for energy applications. MgH₂ is well-known for its high hydrogen capacity but suffers from slow kinetics and high desorption temperatures, limiting its practical application. HEAs, with their multi-element composition and high configurational entropy, offer improved structural stability, hydrogen diffusion, and catalytic properties. By incorporating MgH₂ into HEAs, this research shows the potential of enhancing hydrogen storage performance by lowering desorption temperatures, improving hydrogen absorption/desorption kinetics, and increasing cycling stability. The synergistic effects between MgH₂ and HEAs are critically analyzed, highlighting their potential in energy storage systems. The review also discusses key challenges related to material scalability, long-term stability, and cost, providing insights into future research directions for optimizing MgH₂-HEA systems for hydrogen storage. |
