A Review: The Effect of Operating Conditions and Thermal Management on the Performances of Metal Hydride Hydrogen Storage Tank

Abstract

For safety and operability concerns, the use of metal hydrides to store hydrogen appears to be particularly promising option for alternative energy at present. However, the process of adding, removing and distributing heat during the hydrogen charging/ discharging process is problematic due to the poor effective thermal conductivity of the metal hydride porous bed and the high enthalpies of H 2 adsorption/desorption. Therefore, heat transfer is a critical factor affecting the performance of metal hydride hydrogen (MHR) storage tanks. Over decade, many researches focused on MHR's operating conditions and its thermal management to improve its performance.

Performance Assessment of Spark-Ignition Engine Combined with an HHO Generator

“…Amidst escalating concerns about global warming, reducing reliance on fossil fuels has become imperative. This shift necessitates a greater reliance on renewable and ecofriendly energy sources [1][2][3]. Hydrogen, particularly when sourced renewably, serves as a sustainable energy carrier.…”

“…The use of HHO gas in automotive engines not only promises environmentally benign emissions but also potential enhancements in vehicle performance. Despite these benefits, adopting hydrogen-based technologies, including HHO systems, poses challenges, notably in safe installation and handling due to hydrogen's flammability [3,6]. Given this, numerous studies have explored the efficacy of HHO gas as a supplemental fuel to improve vehicle performance.…”
