Application of multiphase heat transfer for efficient hydrogen storage and recovery

Abstract

This book chapter provides a technical review of the current practice in hydrogen storage and recovery using metal hydride (MH) reactor beds at various operating temperatures. Thermo-chemical processes involved are carefully examined and appraised while identifying practical challenges and performance limitations. Potential enhancements to the current MHs-based hydrogen storage and recovery practice are illustrated through comparative studies of heat transfer media undergoing melting/solidification coupled with low temperature bed reaction and those of heat transfer media subjected to boiling/condensation with high temperature bed reaction. These outcomes identify the merits of multiphase mechanisms for effective thermal management and enhanced performance of hydrogen storage/recovery systems with MH reactor beds.
