Unlocking synergistic effects of mixed ionic electronic oxygen carriers in ceramic-structured environments for efficient green hydrogen storage

Year: 2024

Type: article

Abstract: This study investigates the use of mixed ionic electronic conductors (MIECs) in ceramic structures to enhance green hydrogen storage through Chemical Looping Hydrogen (CLH) technology. A novel method integrates Yttria-stabilized zirconia (YSZ) into a ceramic foam matrix, significantly improving oxygen exchange capacity (OEC) and specific hydrogen productivity (SHP) by 30–40% with YSZ3 and 10–15% with YSZ8. Over 150 cycles, YSZ8 show the best pressure behavior in the fixed-be and doubling the storage capacity compared to conventional materials like pure ZrO 2 . The study also reveals the superior cyclic stability of these materials, maintaining over 80% efficiency across numerous cycles. These advancements not only support safer, more cost-effective hydrogen storage and transportation but also demonstrate strong potential for industrial scalability, crucial for future energy systems and CO₂-neutral technologies. The structured oxygen carriers could revolutionize hydrogen storage by offering a scalable, efficient solution that meets the demands of modern energy infrastructures.
