This review explains the hydrogen separation membranes with various fabrication meth- ods as well as different membrane supports, and it also covers a different type of membrane for hydrogen separation. In recent, the researcher placed an interest in the study of the hydrogen selectivity and per- meability of the membranes. It concluded that the composite palladium membrane developed by electro- less pore plating fabrication technique on porous stainless steel has found a promising application for hydrogen-selective membranes. The use of the palladium membranes in industries has some associated problems such as high cost of pure Pd-based membrane, membrane fouling, and durability of the membrane. Ó 2020 Elsevier Ltd.

Introduction The depletion of fossil fuel day-by-day increases the demand for alternative and clean energy to fulfill the energy requirements [1]. According to the EIA, fuel demand increases very rapidly in the late 2020s and it increases 0.1 mb/d each year. Increasing the automo- bile industry, climate change and air pollution very drastically increases due to the combustion of fuel [2]. As a result, alternative energy is needed to full fill world energy demand and environmen- tally friendly. Many renewable sources such as wind energy, geothermal, solar energy, and biofuels presently the solutions but these are not sufficient to meet the required energy demands [2]. Hydrogen based energy has been sustainable and effective fuel for fuel cells in the automobile industry [3]. To meet economical demands, hydrogen separation and purification have been required. Various technologies available for purification and extraction of hydrogen from other gasses such as wet scrubbing, dry scrubbing, and pressure swing adsorption, membrane separa- tion, cryogenic distillation [4]. Among them, membrane technology has been found appealing due to the advantages like flexibility in operation, simplicity, energy efficiency, compactness, small foot- print, eco-friendly, less operating cost and easy integration with established industrial processes [5]. Performance of membrane has been evaluated by its selectivity, thickness, thermal stability and permeation rate. Several membrane materials, like polymer membrane (glassy and rubbery) and their composites, hydride membrane (metal- based membrane, silicon-based membrane), metal alloys, etc. have been used to prepare hydrogen-selective membrane [6]. In metal- based membranes, various metals used for preparing hydrogen- selective membranes such as vanadium, niobium, and tantalum but among them palladium has been an attractive material that provides high selectivity towards the hydrogen enabling the pro- duction of hydrogen [6]. Furthermore, the hydrogen separation process using dense palladium membrane has focused upon hydrogen atom being selectively transported through the dense metal sheet. Additionally, such type of membranes has been highly oxidation-resistant and had good thermal stability (up to 550 °C) enabling their implementations at elevated temperatures and the essence of the permeation process that involves the higher value of hydrogen solubility and diffusivity into palladium/palladium alloy [7]. Such properties provide significant benefits of hydrogen (H 2 ) purification against other alternatives like polymeric mem- brane and its composite, zeolite membrane, other metallic mem- branes, carbon membrane.
