Project summary description:
This project aims to develop composite structures to improve the heat transfer and durability of metal hydride-based systems. Currently, metal hydride systems are strongly impacted by heat transfer limitations. Metal hydrides also swell as they absorb H2, placing an upper limit on the amount of alloy that can be safely stored in vessels.

Combining metal hydrides with other materials, such as expanded natural graphite, can improve the thermal conductivity. Combining them with polymers/resins can potentially absorb the swelling as H2 is absorbed. This project is exploring three novel pathways for developing these composite structures with the overall aim of improving the performance and durability of metal hydride-based compression and storage.
