“…At present, nearly about 11,200 cars powered by hydrogen are on the road [9]. However, since electric vehicles are gaining a lot of popularity nowadays in spite of having issues like long time of charging and short mileage, since it is environment friendly and comparatively cheaper than fuel cell driven vehicles, hydrogen economy in transportation is lacking a consistent growth [13]. But in the future, transportation sector will be an eminent application of hydrogen as there would not be any GHG emissions [4].…”

The rising population and pollution alarms the need for adoption of renewable technologies over fossil fuels for meeting the increasing energy demands and achieving net zero emissions. However, being intermittent in nature, these renewable sources are highly weather and location dependent which causes a gap between demand and supply of energy. This gap can be filled by hydrogen which is an environment friendly fuel and can be produced from both renewable and non-renewable energy sources. It does not cause GHG emissions and is a promising future energy carrier. Hydrogen has a potential to achieve the target of green economy for the betterment of the future and is gaining popularity nowadays. This paper gives a description of the various types of hydrogen, production processes, applications and challenges faced while adopting hydrogen economy for a safe and sustainable future

“…In fact, 60 percent of hydrogen in the world is used in ammonia preparation followed by oil refining. It is also used in steel processing industry for the production of steel [13]. With hydrogen already being put to use in these sectors, it still has more opportunities to explore.…”

“…Currently, one of the most pressing problems the world is facing is climate change . The demand for fossil fuels, especially coal, natural gas, and oil, has continued to grow very rapidly in recent decades, causing a sharp increase in greenhouse gas emissions, , mainly due to their anthropic origin (industries, domestic use, traffic) and also due to fire and disforestation of tropical forests. , Carbon dioxide concentrations, for example, have grown from 280 ppm in 1780 to 415 ppm in 2019 in the northern hemisphere . Associated with the increase of these greenhouse gases, many scientific studies highlight an increase in the earth’s temperature, − which is leading to extremely negative consequences for human beings, the ecosystems, and the biodiversity of the planet. − …”

The production of activated carbons (ACs) starting from economic precursors using eco-sustainable synthesis processes appears to be a particularly interesting research field. A possible application can be represented by the use of waste materials to produce ACs through synthesis processes with a low environmental impact for hydrogen (H 2 ) storage. In this work, ACs were produced starting from peach pits, through two processes, i.e., carbonization and physical activation of the raw material. The key process parameters (gas type and temperature) and the starting form of biomass were modified to evaluate their influence on the structural properties and, consequently, the H 2 adsorption capacity. The chemical and morphological properties of the ACs were investigated through different analyses (energy-dispersive X-ray, EDX; X-ray diffraction, XRD; Fourier-transform infrared spectroscopy, FTIR; scanning electron microscopy, SEM), while textural features and adsorption capacities were determined using a volumetric apparatus. Optimization of the synthesis process allowed us to obtain ACs with a highly microporous structure (≃85%), a specific surface area of around 1317 m 2 /g, a total pore volume of 0.60 cm 3 /g, an excellent H 2 adsorption capacity at low pressure (1.85 wt % at 77 K up to 1 bar), an interesting H 2 adsorption capacity at high pressure (3.45 wt % at 77 K up to 80 bar), and an excellent cyclicality of storage processes but reduced storage capacity at room temperature (0.28 wt % up to 80 bar).

“…Hydrogen is a very important feedstock, and is prominently used in oil refineries for hydrocracking and hydrodesulphurization of petroleum oils, in ammonia plant for fertilizer production, in metallic ore reduction process for extraction of metals, and in manufacturing of hydrogen peroxide and fuels such as methanol and dimethyl ether. [1][2][3] Currently, a significant focus has been made to use hydrogen as a substitute of natural gas for generation of heat energy, as well as an alternative energy source for electricity generation. 4,5 Due to high energy density of hydrogen (i.e., 33.3 kWh kg À1 ) and its renewable nature, hydrogen has a great potential to provide sustainable power for domestic applications, as well as to chemical and automotive industries.…”

Water electrolysis (WE) is an electrochemical process that splits water and forms hydrogen and oxygen, in presence of catalyst. This is a rapidly developing technology owing to its extreme importance in the generation of hydrogen. Membrane-based WE involves the use of anion exchange, proton exchange and bipolar membranes, among which the anion exchange membrane-based WE technology is in the most advanced stage, followed by the proton exchange membrane-based WE. While, the bipolar membrane-based WE is the most nascent technology. Among the different categories of membranes used, polymer-based membranes are the most acceptable ones. It is evident that the structure and properties of the polymers that constitute a membrane play the most important role in determining its applicability in WE application. Keeping this in mind, this review is dedicatedly focused on the different polymers that have been majorly used so far in fabrication of anion exchange, proton exchange, and bipolar membranes for WE, and exclusively analyzes the influence imparted by the structure and properties of the involved polymers on the final performance of the membranes.
