Materials for Hydrogen Mobile Storage Applications

Abstract

There are several attempts to achieve efficient hydrogen storage. In this article, we introduce four main methods: conventional tank storage, metal and alloys hydrides storage, polymeric materials storage and carbon nanomaterials storage. We illustrate the advantages, disadvantages and current research process of each methods.

PdNi Biatomic Clusters from Metallene Unlock Record‐Low Onset Dehydrogenation Temperature for Bulk‐MgH2

“…Hydrogen is a promising energy alternative to traditional fossil fuels due to its high gravimetric energy density (142.0 MJ kg −1 ) and lower heating value (LHV) of 33.3 kWh kg −1 , which is superior to gasoline (12.4 kWh kg −1 ) and natural gas (13.9 kWh kg −1 ). [1] However, the widespread adoption of hydrogen energy has been impeded by the absence of suitable storage solutions DOI: 10.1002/adma.202303173 that can simultaneously meet a diverse array of requirements including favorable thermodynamics, rapid kinetics, high capacity, robust durability, low safety risks, and low cost. [2][3][4] Developing a one-sizefits-all hydrogen storage solution that satisfies all these criteria remains a significant challenge.…”

Numerical simulation of a thermally driven hydrogen compressor as a performance optimization tool

“…High-pressure tanks of 70 MPa allow storing 6 wt.% of hydrogen considering the whole storage system, but compression requires 15% of the hydrogen lower heating value (LHV). Alternatively, a hydrogen capacity of up to 7 wt.% can be achieved by liquid storage, but hydrogen liquefaction requires about 40% of the hydrogen's LHV, and a high degree of adiabaticity of the storage tanks is almost mandatory due to the very low temperatures [1]. Magnesium-based hydrides, such as MgH2, also allow storing 7 wt.% of hydrogen [2], but metal hydrides are relatively heavy, thus the weight ratio of stored hydrogen to the total storage system can be as low as 1-3% [3].…”

The Deltah Lab, a New Multidisciplinary European Facility to Support the H2 Distribution & Storage Economy

“…To achieve these parameters, different storage techniques have been developed: gas compression (cGH 2 ), liquefaction (lH 2 ), cryo-compressed (CcH 2 ), liquid (LSMs), and solid-state materials (SSMs), which involve the H 2 interaction with the bulk (Chemisorption-Chem) or the surface (Physisorption-Phys) of materials [18,19]. cGH 2 is the most popular storage solution for both stationary and mobile applications, which requires expensive tanks, due to considerations on materials, geometry and mechanical properties, compression, and fast filling resulting in energy expenditure [12].…”
