The world is looking for clean and green energy as substitution for fossil fuels to minimize the greenhouse effect and climate changes threatening our existence. Solar energy, wind energy, and hydrogen gas‐based energy are few examples of promising sources of energy alternatives to fossil fuels. Hydrogen gas‐based energy is in focus today due to its availability in plenty of combined forms such as water, hydrocarbons, natural gases, etc. However, its storage and transportation are major challenges due to the low volumetric density and explosive nature of hydrogen. The scientific community is in search of suitable, economically viable, and energy‐efficient storage systems and transportation of hydrogen gas. Based on numerous studies, surface adsorption of hydrogen by high surface area nanoporous solids such as carbon and metal–organic framework (MOF)‐based nanofiber materials are most suitable for storage applications. Electrospinning process provides a gateway for the preparation of lightweight, highly porous nanofibers for efficient hydrogen adsorption. Herein, the production and use of electrospun polymer nanofibers and MOFs for the storage and transportation of hydrogen are presented.

Biomass gasification is a viable solution for generating H 2 ; however, the syngas produced must be upgraded to make H 2 -containing streams suitable for other applications, such as renewable methanol production, by adjusting the H 2 /CO ratio. In this study, for the first time in the literature, the separation properties of carbon hollow fiber membranes in binary and quaternary H 2 -containing mixtures with varying compositions were systematically explored. It was found that the developed carbon membranes exhibit relatively good selectivity for (H 2 +CO 2 ) in mixtures with other gases such as N 2 and CO, which are commonly present in syngas. A CO permeance of 0.8−1 GPU and a H 2 /CO selectivity of 30 were achieved for the first time through both single gas and mixed gas permeation testing. Furthermore, in the context of using these membranes for syngas upgrading, such as in an integrated biomass-to-biofuel (methanol) process for hydrogen enrichment or carbon capture and conversion, a technical feasibility analysis based on the separation performance of the carbon membrane system for syngas ratio adjustment and N 2 removal was carried out. The results indicate that the prepared carbon membranes have the potential to adjust the H 2 /CO ratio to 1−3 if a N 2 removal ranging from 80 to 90% is acceptable.

“…Byproducts such as CO 2 are simultaneously generated during these processes, necessitating additional hydrogen purification steps. [2][3][4] Using membranes to separate hydrogen from gas mixtures is not new. Although polymeric membranes remain the most used for large-scale applications, they have limitations regarding harsh environmental exposure and provide limited hydrogen permselectivities.…”

Hydrogen separation using nanostructured membranes has gained research attention because of its potential to produce high‐purity hydrogen by separating gases at the molecular level. Quadrupole mass spectrometry (QMS) is one method to evaluate these membranes' effectiveness in separating hydrogen from gas mixtures. However, quantifying gases in a mixture with QMS is challenging, especially when heavier gas ions interfere with a light gas ion, resulting in lower quantification accuracy. This study addresses this challenge by presenting a detailed calibration procedure that significantly improves hydrogen quantification accuracy up to a factor of 2.5. CO and CO2 were chosen as interfering gases because they are commonly released in conventional hydrogen production processes. By carefully evaluating the performance of these membranes, new opportunities for hydrogen separation may be realized.
