Green Hydrogen has several different uses, such as producing petroleum products, manufacturing fertilizers, ammonia, and even in the industry or steel, Hydrogen (H) is the purest form of energy and thus it has become the primary ingredient for people to generate & satisfy the required amount of energy.

Green Hydrogen can be formed with electrolyzed power of water using non-conventional sources of energy like wind or solar. Though hydrogen is the most abundant element in the universe only 0.14% is available on earth crust. Let us find out the percentages through this table

Composition of Hydrogen	Percentage
Earth’s Crust	0.14
silicon	28.5
Human Body	10
Air	0.00005
Water	11.11

To encourage the use of electric vehicles Indian Oil Corporation along with the Gujarat Government has decided to initiate a hydrogen dispensing facility at its Gujarat Refinery

Participation of Airox Nigen

Airox Nigen Equipments Pvt. Ltd. is a Gujarat (India) based company. It was established in 1994 by Mr. Anil K Agrawal, who is having almost 30 years of experience in the field, and M/s Surbhi A Agrawal, having 20 years of administrative experience. In time the company has grown so much that today they do not only have customers in India but also in many different countries.

They are well equipped in the field of adsorption. They provide Hydrogen generation services both by water and by methanol cracking. As Green Hydrogen is the concern of this article, we will discuss the details about Hydrogen generation from water.

How much Airox-equipped Airox Nigen is?

Airox Nigen is one of the leading companies in the industry of adsorption technology.

In unit 1 (Changodhar) they have 30000 sq. feet of Total Area, machinery like Hydraulic Press – 75 T, Radial Drill – 32 mm 2.5 HP, Heavy Duty Lathe – m/c4’ long Bed, Welding Transformer – 600 Amps, Angle Grinder – 7” wheel Día, HF Unit for TIG – 400 Amps, etc.

In unit 2 (Changodhar) they have 8000 sq. feet of Total Area and Machinery like Arc Welding m/c, Surface Grinder Bench Mounted, Argon Welding m/c, Tube expander’s sets, and many more.

In Unit 3, (Vapi Gujrat) the total area is 4500 sq. feet and equipment like Hand Grinders, Column drill-25mm and tube expanders’ sets are available there too.

More details are available on their website. In fact, one can get the complete list of equipment over there.

Benefits They offer: Hydrogen is an essential element to the future of our planet. Green hydrogen produced by electrolysis does not remove oxygen from the atmosphere and in that process, Airox Nigen can provide some remarkable outcomes.

• Apart from being well-equipped, they have more than 15 years of experience in this field, which will definitely reflect the quality of their work and this is why 4000 working units all over the world.
• They can run this project with minimal space, minimum maintenance cost, low power consumption, and that too with proven technology for electrolysis
• The Hydrogen they provide is pure, up to 99.9999%
• In case of any emergency abnormal issue, the generator will stop automatically with emergency alarms.
• They provide customized service to each of their customers according to the size of the hydrogen generator plant.
• Remote monitoring and control are other benefits, it will help the generator to stop when the storage tank gets filled and also restart when the pressure reduces in the tank.

 Reasons to Choose Hydrogen!

Hydrogen is a carrier of energy with many useful applications. It can be used to supply fuel to vehicles or raw materials for industry. New possibilities can be opened up with hydrogen energy.

1) It is clean energy with 0 emissions. It does not affect the quality of air much and is good for public health.

2) It can be a connector of electricity gas and transportation.

3) It has multi applications & it brings more flexibility in terms of demand and production.

4) It is affordable as well as valuable.

5) It is the pure form of energy and performs three times better than diesel.

Advantages of Green Hydrogen

• Hydrogen is the most abundant element in the universe and it can create energy without releasing CO2.
• Can be used as a substitute natural for cooking.
• Green hydrogen is a great resource to burn hydrogen.
• It can be stored easily.
• It is easy to convert into synthetic gas easily.
• In the case of the space mission, it works as a generator of drinking water.

IOC has decided that they would produce hydrogen production units as it will be the fuel of the future. To do that they would start with the project of Gujarat refinery to produce 99.9999% pure hydrogen. It was expected that at least 15 buses will run in the year 2021 which are fuel cell-powered. IOC has decided to set up a plant of 200-400 tons per day capacity. It is reported that through 2030 the demand for hydrogen will grow at a moderate rate and will be used in industries, transport, and many other industries and the cost will decrease by 30% by then. The production cost of green hydrogen will be €1 to €1.5/kg in China, the US, Russia, Africa, and a few other countries and €2/kg in Japan, Europe, or Korea by 2050.

The Conversion Process of Air to Hydrogen (Generation of Green Hydrogen)- 1st Time in Gujarat

The generator provided by Airox works on a Bipolar pressurized water electrolysis-based system. Each of the electrolyzers is designed for an extra capacity of 10%. The main component of the generator is electrolyzed where water is decomposed into hydrogen and oxygen.

Two cells whereby oxygen is generated on anode and hydrogen is generated on the cathode. Electrolyze is filled with electrolyte mixed with DM water, along with a transformer which is used to change high AC voltage to low AC voltage through rectification by the rectifier.

The positive pole is connected with the anode of the electrolyzer, the cathode of the electrolyzer is connected to the negative pole. Once the DC current is passed, the electrolyte is being circulated and the hydrogen and oxygen generated are sent hydrogen and oxygen separators.

Teleoperators are separated with electrolytes due to gravity and electrolytes come down. The electrolyte at bottom of the separators by gravity comes back and is pumped back to separators filtering and cooling.

While the hydrogen gas is generated and collected for further use, the oxygen generated can also be collected for separate use or vented as per need. This hydrogen generated from electrolysis is 99.99% pure.

The hydrogen plant is designed for a pressure of a minimum of 10 barges to a maximum of 30 barges. In case higher pressure is required, an oil-free diaphragm-type hydrogen booster can be provided.

With all the safety procedures for employees and factory workers and ensuring adequate standards of the industry, Airox Nigen is paving its path towards success efficiently.
