A constellation of technologies has been researched with an eye toward enabling a hydrogen economy. Within the research fields of hydrogen production, storage, and utilization in fuel cells, various classes of materials have been developed that target higher efficiencies and utility. This Review examines recent progress in these research fields from the years 2011–2021, exploring the most commonly occurring concepts and the materials directions important to each field. Particular attention has been given to catalyst materials that enable the green production of hydrogen from water, chemical and physical storage systems, and materials used in technical capacities within fuel cells. The quantification of publication and materials trends provides a picture of the current state of development within each node of the hydrogen economy.

“…Among others, storage and transportation remain key challenges to the implementation of hydrogen technologies because of unacceptable small volumetric energy density under normal conditions. Various methods for increasing the density of hydrogen have been explored 1‐3 . Liquefaction allows users to obtain the maximum ratio of stored energy to mass but requires a complex and expensive infrastructure.…”

Summary The hydrogen storage performance of a series of Basolite metal‐organic frameworks (MOFs) has been estimated within a pressure range up to 700 bar at temperatures from 77 to 293 K. Crystal structure and texture properties of the MOFs were determined using X‐ray diffraction and nitrogen cryoadsorption, respectively. Hydrogen excess adsorption isotherms were measured and then converted to gravimetric and volumetric total adsorption. To calculate the total volumetric capacity, the crystallographic density of materials for the theoretically maximum capacity was used. At 700 bar, the highest volumetric total adsorption was about 65 mg/cm3 shown by Z1200 and Z377. The heat of adsorption at 298 K vs pressure was evaluated by the Clausius‐Clapeyron equation. Peculiar adsorption behavior of C300 in the high‐pressure region manifested in specific forms of isotherms and baric dependence of the heat of adsorption has been revealed. The relation of this phenomenon with a possible transition from Cu2+ to Cu+ in the C300 framework under the reducing effect of hydrogen has been discussed. The upper‐pressure limit of the MOFs' effectiveness in hydrogen storage systems compared to adsorbent‐free compressed gas has been estimated and did not exceed 127 bar at 298 K and 82 bar at 77 K due to the large amount of hydrogen that remains adsorbed at release pressure 5 bar. It has been concluded that conventional testing methods based only on excess adsorption isotherm measurements give initial data on the surface interaction and do not reflect the actual amount of stored and deliverable hydrogen. Besides the excess adsorption, the density of the adsorbent and the low‐pressure capacity are the key factors defining the applicability of materials in high‐pressure storage systems.

“…However, liquid nitrogen is also used during the hydrogen liquefaction process, which is considered a viable option for large-scale storage or transportation [8,15]. Cryoadsorption further improves the cryocompression technique, reaching higher storage density for the same pressure and temperature [16,17]. Finally, physisorption-based storage systems can be an alternative to mechanical compressors because, as thermally driven compressors, they have a smaller size due to the adsorption-desorption cycle, low maintenance costs due to the absence of moving parts, no noise and vibration, and a potentially favourable energy balance [16,17].…”

Physical adsorption at cryogenic temperature can increase the density of the stored hydrogen at a lower pressure than conventional compressed gas systems. This mechanism is also reversible and involves faster kinetics than chemical storage. Materials with certain structural and porous properties are necessary for volumetrically efficient hydrogen storage, including large specific surface areas, pore volumes, and appropriated bulk densities. Metal-organic frameworks (MOF) materials are remarkable candidates as adsorbents due to their porous properties and high crystallinity. Large databases like the MOF subset from the CSD or the CoRE-MOF can be used to find the best materials for this application, providing crystallographic information, composition, and porous properties. Herein, we created a database which includes crystallographic and porous properties, metallic and organic composition, and the minimum available cost for their linkers and corresponding suppliers for those for which it was publicly available. The database is also helpful for selecting structures with potential for industrial production and starting material for computational tools like machine learning or artificial intelligence approaches that relate the composition of MOFs with their performance in different applications. A user interface allows for creating customized selections of suitable MOF structures, looking for their porous and crystalline properties, gravimetric and volumetric total uptakes, and metallic and organic composition, as well as properties for the organic linkers like name, molecular mass, price, or presence of specific functional groups. This information was used to select potential structures from up to two metals and two linkers for the volumetric cryostorage of hydrogen.
