Baowu Magnesium and Hydrexia Holdings to collaborate on the development of magnesium alloy for solid-state hydrogen storage. 

Lightweight materials producer Baowu Magnesium Technology and hydrogen storage solution provider Hydrexia Holdings have agreed to form a strategic partnership to use their combined expertise towards the development and optimisation of solid-state hydrogen storage. This includes production of magnesium alloy, performance optimisation of magnesium alloy hydrogen storage, and processing and recycling of magnesium pellets. The two have also agreed to collaborate on marketing strategies to broaden the industrial applications of magnesium-based solid-state hydrogen storage. The partnership is set to begin in January 2024.

Magnesium (metal hydride) as a hydrogen storage material has been extensively investigated over the past decade due to both its widespread availability and its notably high gravimetric and volumetric storage densities. However, limitations such as cost, efficiency, and power conversion are still inhibiting the large-scale adoption of magnesium-based solid-state hydrogen storage as a popular technology.

Magnesium metal demand is anticipated to grow by almost 400kt from 2023 to 2033, with almost 70% of magnesium applications focused on the aluminium and die-casting industries. Solid-state magnesium metal hydride technology would open a new demand sector for magnesium and gain the metal direct exposure to energy transition technologies, which are currently limited mainly to light-weighting.
