Two senior scientists at the Baotou Rare Earth Research Institute used the lead-up to China’s annual National People’s Congress meetings to highlight new advances in rare earth technologies—particularly artificial intelligence-assisted materials research and rare earth–based hydrogen storage systems. The developments, reported by the Chinese state-affiliated outlet Baogang Daily, illustrate how China is increasingly combining digital technologies with materials science to strengthen its already dominant rare earth industrial ecosystem.

Overview: A REE AI Model

Yan Hongwei, a senior researcher at the institute and a delegate to China’s National People's Congress, described an initiative to integrate artificial intelligence into research on rare earth materials. According to the report, his team is developing a “Rare Earth AI” model to accelerate the discovery and optimization of advanced rare-earth materials. The system would use large datasets and machine learning tools to improve efficiency across the research pipeline—from laboratory experiments to the industrial development of new materials.

Yan has spent more than 2 decades in rare-earth research. His earlier work included the development of room-temperature magnetic refrigeration materials, a technology being explored as an alternative cooling method that avoids traditional gas-compression refrigerants. He also helped establish China’s first rare-earth capital-market index, the CRE Index, and contributed to industry analyses documenting the development of China’s rare-earth sector. His current research focuses on applying AI tools to accelerate the development of next-generation rare-earth materials.

Hydrogen Storage

Another scientist featured in the report, Li Baoquan, focuses on rare-earth hydrogen-storage technologies. His team recently completed a major demonstration project in Inner Mongolia that integrates wind and solar power generation with hydrogen production, hydrogen storage, and fuel-cell electricity generation. According to the report, the system addresses technical challenges associated with balancing intermittent renewable power sources with stable energy output.

Li’s research group has also improved the performance of rare-earth alloys used in solid-state hydrogen storage materials. The materials—based on combinations of lanthanum, yttrium, and nickel—are designed to safely store hydrogen as solid metal hydrides. The report claims the team increased storage capacity from approximately 1.3 kilograms to 1.7 kilograms of hydrogen per 100 kilograms of material. Their technologies have reportedly been tested in applications including heavy trucks and electric bicycles. To date, the group holds three international patents and 26 Chinese invention patents related to rare-earth hydrogen-storage materials.

Westward POV

For Western industry observers, the report highlights two strategic directions within China’s rare earth ecosystem: the application of artificial intelligence to accelerate materials discovery and the continued integration of rare earth materials into emerging hydrogen and clean-energy systems.
