In April 2025, significant advancements were made in solid-state hydrogen storage technology, particularly in rare earth-based and magnesium-based materials. Rare earth-based materials like LaNi₅ and MmNi₅ demonstrated high power density, wide temperature range stability, and an impressive cycle life, with recent breakthroughs in new alloys and low-cost mass production. These materials find applications in fuel cell vehicles, distributed power generation, and emergency backup solutions. Magnesium-based materials, on the other hand, offer low-cost energy storage options with breakthroughs in nanostructure modification and catalyst optimization. These materials are being utilized for storing fluctuating renewable energy sources with reduced system costs. Collaborative efforts between domestic and international entities are driving the industrialization of these technologies, with China focusing on rare earth-based advancements and Germany leading in magnesium-based innovations.
