Advancing Pellet Durability: Fundamental Research by Team SOLID

As Team SOLID progresses in pioneering hydrogen storage solutions, a key focus of 2024 is on enhancing the durability of the iron pellets used in the innovative Steam Iron process. These pellets, a cornerstone of the Iron-Based Hydrogen Storage (IRHYS) system, are crucial for the sustainable and efficient release and storage of hydrogen. However, to meet the high demands of this process, these pellets need to be robust, efficient, and capable of enduring multiple cycles of use.

Why pellet research matters

The current pellets, originally designed for traditional steelmaking, are not ideally suited to the rigorous demands of the IRHYS cycle. While these pellets achieve full reduction in hydrogen production, they face challenges in oxidation and structural integrity after a few cycles. This research aims to address these issues, extending the lifespan of each pellet and ensuring reliable, efficient hydrogen storage.

The research approach

Team SOLID is undertaking a comprehensive study to tailor a new generation of iron pellets. The team’s approach involves:

– Testing and Feedback Loop: A continuous cycle of testing and refining pellet recipes based on real-world performance. Initial batches are produced using DIY methods, allowing the team to gather data quickly and adjust the recipe for durability and performance.

– Material Composition: By experimenting with different binding materials and pellet sizes, the team is identifying combinations that withstand the repetitive oxidation-reduction cycles.

– Advanced Production Techniques: While early research relies on simpler, in-house equipment, future stages will utilise high-quality production tools to maintain consistency and quality as the ideal recipe emerges.

Impact of durable pellets

The success of this fundamental pellet research will be transformative for the IRHYS technology, making hydrogen storage more efficient and reliable. A pellet specifically designed for the IRHYS cycle could endure repeated use without degradation, leading to cost savings and performance improvements for future users.

Through this innovative research, Team SOLID is setting the foundation for a more durable, reliable, and sustainable hydrogen storage technology—empowering industries to adopt green energy with confidence.
