Things You Should Know About the Uses of Hydrogen

Hydrogen will be one of the critical assets in the energy stream in the coming decades for the sustainable development of society. The abundant availability of hydrogen and its application in electricity production using fuel cells without any harmful emissions makes it distinct. It can be produced from renewable and sustainable resources, thus promising an eco-friendly solution for the energy transition in the coming years.

Currently, hydrogen production using the electrolysis of water is most preferred. However, hydrogen production can vary in the range of sectors. Hydrogen can be used in electricity production, biomass, solar and wind power application.

applications of hydrogen gas

Despite its advantages, two significant issues hinder its commercialisation and generalisation as an efficient fuel, and energy transition toward zero-emission and fossil-free energy solutions. The first is hydrogen is an energy vector, which means hydrogen needs to be produced before its use and eventually lead to energy consumption in hydrogen synthesis. The second is the low volumetric energy density of hydrogen, which leads to hydrogen storage and transportation issues because of its lowest volumetric energy density (0.01079 MJ/L)

Researchers have suggested several solutions to attempt to increase this value:

  • compression in gas cylinders;
  • liquefaction in cryogenic tanks;
  • storage in metal-hydride alloys;
  • adsorption onto large specific surface area-materials
  • chemical storage in covalent and ionic compounds (viz. formic acid, borohydride, ammonia)

Applications of Hydrogen

The hydrogen applications are in the food industry to turn unsaturated fats and oils present in vegetable oils, butter into a saturated state. In the metal forming industry, atomic hydrogen welding is used as an environmentally sustainable welding process. In the manufacturing industry, hydrogen and nitrogen are used to create a boundary and prevent the oxidation of metals.

The recent advancements in hydrogen applications in the steel manufacturing industry are one of the most significant hydrogen applications for low or zero-emission iron ore conversion.


The potential use of hydrogen can play a vital role in reducing greenhouse emissions and the global target of achieving a minimal no emission target by 2050. However, the automotive industry is still the largest consumer and most attractive sector in the current scenario. But with the future forecast of reducing hydrogen fuel cost can do wonders with the goal set during Paris Climate Summit.

Hydrogen use in stationary and automotive applications, such as fuel cell vehicles and hydrogen refuelling stations above all, has shown to be hindered by its volumetric energy density – the lowest among all the standard fuels nowadays used. Compression seems to be the most efficient solution to reach high storage levels, thus making hydrogen more common as a renewable and sustainable fuel.

The availability of several hydrogen compression technologies makes the development of new innovative and environmentally-friendly solutions for the use of energy possible, leading to a transition towards a fossil fuel divestment and making a critical contribution to sustainable development

Everything You Need to Know About Carbon Black

Carbon Black is a commercial form of solid carbon that is manufactured in highly controlled processes to produce specifically engineered aggregates of carbon particles that vary in particle size, aggregate size, shape, porosity and surface chemistry. Carbon Black typically contains more than 95 % pure carbon with minimal quantities of oxygen, hydrogen and nitrogen.

In the manufacturing process, Carbon Black particles range from 10 nm to approximately 500 nm in size. These fuse into chain-like aggregates, which define the structure of individual Carbon Black grades.

What is Carbon Black

Carbon Black is used in a diverse group of materials in order to enhance their physical, electrical and optical properties. Its largest volume use is as a reinforcement and performance additive in rubber products.

In rubber compounding, natural and synthetic elastomers are blended with Carbon Black, elemental sulphur, processing oils and various organic processing chemicals, and then heated to produce a wide range of vulcanized rubber products. In these applications, Carbon Black provides reinforcement and improves resilience, tear-strength, conductivity and other physical properties.

Carbon Black is the most widely used and cost effective rubber reinforcing agent (typically called Rubber Carbon Black) in tire components (such as treads, sidewalls and inner liners), in mechanical rubber goods (“MRG”), including industrial rubber goods, membrane roofing, automotive rubber parts (such as sealing systems, hoses and anti-vibration parts) and in general rubber goods (such as hoses, belts, gaskets and seals).

Applications of Carbon Black

Besides rubber reinforcement, Carbon Black is used as black pigment and as an additive to enhance material performance, including conductivity, viscosity, static charge control and UV protection. This type of Carbon Black (typically called Specialty Carbon Black) is used in a variety of applications in the coatings, polymers and printing industries, as well as in various other special applications.

Actually, after oil removal and ash removal processing from tire pyrolysis, we can get high-purity commercial carbon black, which can be used to make color masterbatch, color paste, oil ink and as addictive in plastic and rubber products. Besides, after activation treatment, the carbon black will become good materials to produce activated carbon.

In the coatings industry, treated fine particle Carbon Black is the key to deep jet black paints. The automotive industry requires the highest black intensity of black pigments and a bluish undertones.

Carbon Black has got a wide array of applications in different industries

Small particle size Carbon Blacks fulfill these requirements. Coarser Carbon Blacks, which offer a more brownish undertone, are commonly used for tinting and are indispensable for obtaining a desired grey shade or color hue.

In the polymer industry, fine particle Carbon Black is used to obtain a deep jet black color. A major attribute of Carbon Black is its ability to absorb detrimental UV light and convert it into heat, thereby making polymers, such as polypropylene and polyethylene, more resistant to degradation by UV radiation from sunlight. Specialty Carbon Black is also used in polymer insulation for wires and cables. Specialty Carbon Black also improves the insulation properties of polystyrene, which is widely used in construction.

In the printing industry, Carbon Black is not only used as pigment but also to achieve the required viscosity for optimum print quality. Post-treating Carbon Black permits effective use of binding agents in ink for optimum system properties. New Specialty Carbon Blacks are being developed on an ongoing basis and contribute to the pace of innovation in non-impact printing.
