A comprehensive review of the prospects for future hydrogen storage in materials‐application and outstanding issues

Abstract

The ongoing population explosion has led to the rapid consumption of different energy sources. The continuous demand for energy and its associated services for socio-economic development is concerning due to the reduction of natural energy sources. Therefore, research to explore clean and sustainable energy sources to fulfill this energy demand has continuously been conducted over the past decades. Hydrogen is widely accepted as a possible energy carrier owing to its advantages, such as ease of availability, renewability, and environmentally friendly nature. Hydrogen storage in the liquid or gaseous form poses safety and transportation challenges. In this context, metal hydrides are a vital solution. This review article discusses unique collections of HEA-based metal hydrides for the first time in conjunction with conventional metal hydrides. This article can potentially guide the materials research community in understanding the current challenges associated with designing novel hydrogen storage alloys from a clean energy perspective and their applications.

Highly efficient hydrogen storage of a Sc decorated biphenylene monolayer near ambient temperature: ab initio simulations

“…So alternative materials are constantly being explored and characterized by their ability to adsorb/absorb hydrogen. They are mainly found as hydrides [17], porous materials [18], and carbon nanomaterials [19] which we will discuss briefly. Hydrogen absorbing materials and its container to store H2 for application purposes are called solid-state hydrogen storage devices.…”

Understanding the modulation mechanism of B-site doping on the thermochemical properties of CaMnO3−δ: an experimental and computational study

“…Thermochemical energy storage, characterized by high energy density, wide operating temperature range, and long-term storage, is the most suitable option for energy storage systems in new-generation CSP power plants. 8,9 The main thermochemical energy storage systems include amino energy storage, 10,11 metal hydride energy storage, [12][13][14] carbonate energy storage, 15,16 metal oxide energy storage, [17][18][19][20][21] and hydroxide energy storage. [22][23][24] The metal oxide system realizes the storage and release of heat through the reversible transformation (redox) of the metal ions' valence.…”

Surface morphology transformation and densification behaviour of conventionally sintered AlFeCoNiSi high entropy alloys

“…Moreover, a better choice for energy conservation is to consume less energy. Thus there is an urgent demand for these kinds of energy-saving measures [1]. On the contrary together, energy can be straight away saved while the components are being produced.…”
