Fossil fuels, which are extremely harmful to the environment and not renewable, predominantly serve the majority of the world's energy needs. Currently, hydrogen is regarded as the fuel of the future due to its many advantages, such as its high calorific values, high gravimetric energy density, eco-friendliness, and nonpolluting nature, as well as being a zero-emission energy source. For sustainable global growth, it is essential to produce and store hydrogen on a large scale by utilizing renewable energy sources. However, hydrogen storage systems, particularly for vehicle on-board applications, face challenges in terms of developing energy-efficient and affordable techniques and materials due to hydrogen's buoyancy, lightness, and high diffusivity. This Review systematically discusses various hydrogen storage methods and materials, including physical storage like compressed gas, physical adsorption storage like carbon-based materials, metal−organic frameworks (MOFs), and other porous materials, as well as chemical storage like ammonia, methanol, formic acid, liquid organic hydrogen carriers (LOHCs), metal hydrides, and two-dimensional MXene-based materials. The advantages of various storage mechanisms are thoroughly discussed, as well as any potential implementation difficulties for realworld uses and future prospects.

“…As their name implies, metal hydrides are compounds containing metal(s) and hydrogen. Magnesium hydride [132] is an attractive material for hydrogen storage because of its abundance and affordability [133]. With a density of 1.45 g/cm 3 , the energy densities of this raw material are 7.6 wt % and 13.22 MJ/L.…”

Hydrogen Storage for Mobility: A Review

2019

View full text Add to dashboard Cite

Numerous reviews on hydrogen storage have previously been published. However, most of these reviews deal either exclusively with storage materials or the global hydrogen economy. This paper presents a review of hydrogen storage systems that are relevant for mobility applications. The ideal storage medium should allow high volumetric and gravimetric energy densities, quick uptake and release of fuel, operation at room temperatures and atmospheric pressure, safe use, and balanced cost-effectiveness. All current hydrogen storage technologies have significant drawbacks, including complex thermal management systems, boil-off, poor efficiency, expensive catalysts, stability issues, slow response rates, high operating pressures, low energy densities, and risks of violent and uncontrolled spontaneous reactions. While not perfect, the current leading industry standard of compressed hydrogen offers a functional solution and demonstrates a storage option for mobility compared to other technologies.
