“…A typical schematic illustration for fabricating hollow silica spheres using spray drying methods is summarized in Figure13b, which consisting stages of spraying, surface enrichment, and organic pyrolysis. [129] Subsequently, Figure 13c and Figure 13d showed FESEM and TEM images of the hollow silica particles. As can be observed, the hollow particles showed regular shape and size signifying an independent effect of the synthesis parameters (pH, TEOS, and ethanol-water ratio) on the successful formation of the hollow sphere nanostructures.…”

Hydrogen plays a crucial role in the future energy landscape owing to its high energy density. However, finding an ideal storage material is the key challenge to the success of the hydrogen economy. Various solid‐state hydrogen storage materials, such as metal hydrides, have been developed to realize safe, effective, and compact hydrogen storage. However, low kinetics and thermodynamic stability lead to a high working temperature and a low hydrogen sorption rate of the metal hydrides. Using scaffolds made from porous materials like silica to confine the metal hydrides is necessary for better and improved hydrogen storage. Therefore, this article reviews porous silica‐based scaffolds as an ideal material for improved hydrogen storage. The outcome showed that confining the metal hydrides using scaffolds based on porous silica significantly increases their storage capacities. It was also found that the structural modifications of the silica‐based scaffold into a hollow structure further improved the storage capacity and increased the affinity and confinement ability of the metal hydrides, which prevents the agglomeration of metal particles during the adsorption/desorption process. Hence, the structural modifications of the silica material into a fibrous and hollow material are recommended to be crucial for further enhancing the metal hydride storage capacity.

“…Short‐term battery electricity storage for small plants is changing dynamically, 32 but reliable autonomy over a long period (from a few hours to a few days) makes a hydrogen energy system the most optimal sustainable option for large‐scale projects and long‐term energy storage because of its high power rates 33 . Renewable energy storage in the form of hydrogen has the advantages of being large‐scale, long‐term, and seasonal 34 …”

Summary Natural resources’ unexpected nature makes renewable energy sources’ power supply irregular and inflexible; weather conditions are impossible to be predicted. Energy storage systems are required to balance this green power supply and ensure both off‐grid and autonomous infrastructures' stability and reliability. Various energy storage technologies are available, but the high initial capital cost and the uncertainty regarding future cost and performance are critical bottlenecks for possible investors. Batteries are the most common energy storage means, while hydrogen storage is one of the least used options. This research attempts to conduct a comparative technoeconomic analysis between a hybrid renewable energy power plant combined with a hydrogen energy storage system and the implementation of the cold‐ironing technique. The test bed is the port of Milos, which is a Mediterranean island port. Thirteen scenarios were conceptualized, simulated, and assessed after examining and assessing the existing methods and technology using MATLAB and Homer Pro software. The economy of scale plays its role in this aspect as hydrogen storage systems' cost has been proven to be lower for larger infrastructures. Indicatively, the levelized cost of energy is significantly reduced for the two optimal scenarios, as there is a 41.3% decrease for the non‐cold‐ironing case and a 33.4% decrease for the cold‐ironing one. Moreover, the carbon footprint for the suggested systems of all the examined scenarios is almost diminished, paving the way forward for turning the port into a nearly Zero Energy Port. This study also helps to comprehend the technoeconomic characteristics of hydrogen‐based hybrid renewable energy systems for supporting the cold‐ironing technique. HIGHLIGHTS A systematic methodology is presented to introduce the cold‐ironing technique to a small Mediterranean port; Hydrogen‐based renewable energy systems are a sustainable and feasible solution toward the nZEP concept; An optimally sized hybrid renewable energy system guarantees the unhampered 24‐h port's operation; The suggested hybrid systems are capable of covering the port's energy needs fully even if the cold ironing is incorporated.

“…Moreover, core‐shell like structured fillers 32, hollow structured fillers 33, 34 and surface functionalized two‐dimensional fillers 35 have revealed to dwindle the aggregation as well as probability of developing conductive pathways in composites. Besides, hierarchical structures indicating multiple interfaces and gradient layered structures, can be formed to overwhelm and prevent the dielectric loss of composites 36.…”

This work presents a technical investigation and review of the development of mixed matrix membranes (MMMs) employed in different applications to save electrical energy. The MMMs design has been recently adjusted and improved to restore more energy bulks. The important factors to control the performance of the MMMs are the penetrant type, membrane matrix, and polymer‐filler interface interactions. This study reviews the current methods to deal with dielectric MMMs and smart nanomembranes for energy saving. These methods include ferroelectric membrane fabrication, dielectric permittivity, conductive dopants, construction of nanocomposites with modified surfaces, and the usage of combined effects. Most chemists and scientists have dedicated all their efforts to develop the attributes of dielectric materials at various electric fields and to find their relationship with chemical construction, composite morphology, and particle density.
