Increase Green Energy To Minimize Huge Oil Import

India with developing economy has population of 1.3 billion people and per capita energy consumption is about 0.6 tonne of oil equivalent (TOE) as compared to World. The average of the TOE is 1.8 tonne.

Today, India has about 18% of the total world population but we consume only 6% of the world’s primary energy. We need to increase our energy consumption at least 4 times to get into the upper middle-income country clubs. Now, if this requirement increases, we will need energy that is clean and indigenous to keep the environment clean in terms of Green House Gases and save foreign currency. 

Our primary aim should be to seek suitable clean energy to meet the energy targets. We all know, India imports a humongous amount of crude oil primarily for the energy needs of vehicles, industry thermal heating and manufacturing chemicals.

According to last year statistics, India spent about 100 billion USD to import crude oil. The country exported goods total of about 220 billion USD and imported a total of 250 billion USD which includes crude oil import of 100 USD. Now if somehow, we can reduce the import of crude oil, we can change the balance of payment scenario on its head. India and the world are on the threshold of technologies. The world has done significant developments in space technologies. We have seen space tourism boost in the recent past. This has resulted in the research and development of fuels. World giant, Tesla has introduced technology in EV (Electrical Vehicles) which is hugely successful. We Indians need to take cues from all this and somehow take a step to reduce our energy imports. Crude oil usage is primarily in the following sectors:

1. Vehicular fuels

2. Thermal fuels for industry 

3. Chemical and fertilizer manufacturing

In addition to these three usages, India also uses coal as fuel to generate power. We make about 250 GW power by coal and about 280 GW of power by the solar route. This means, of the total power generation, 60% of the power generation comes from Solar the route has tremendously reduced greenhouse gases and Carbon print but a lot is needed to be done to reduce carbon footprint especially with increasing energy demands.

Now, with this background, here is what India should do to become energy sufficient and return to its glory which once we had. 

1. Adopt EV as national policy

We need to have a time-bound government policy to replace all the vehicles with Electrical. Today, sufficient technologies are available for the batteries to be lasting more than 1000 Km ride. Sufficient investment is required for the battery charging stations. Today, buses trucks, cars, and even trains can be worked out on EV technology. It’s time India has a national policy on EVs. Charging of the batteries can be done by installing more Solar Power Plants. Hydrogen cells technology is also available to charge the batteries automatically. Five minutes of fill of Hydrogen can change the battery for more than 2000 Km ride. We will save a huge amount of foreign currency by this step, and we will make our environment clean.

2. Research, Development and implementation of Hydrogen based Technologies

Huge work is done worldwide to use hydrogen as a fuel for vehicles. Brands like Toyota, BMW, Range Rover, Jaguar, GM etc. have already invested in hydrogen fuel cell technology. Earlier Hydrogen was very difficult and dangerous to store. But now as technology is available to store hydrogen, flood gates have opened to use this technology. This is a clean technology with water as a byproduct. Hydrogen can be produced by coal gasification known as Brown Hydrogen and that produced by water is called Green Hydrogen. If produced by Natural Gas, it’s called grey Hydrogen and when produced by hydrocarbons, its’s called Blue Hydrogen. Hydrogen is the most acceptable gas for tomorrow for thermal use as it results in no carbon footprint. We are thus positioned to have negative GHG emissions to restore our glaciers, forests and ambient temperatures. 

India has already taken a leap with the first Hydrogen mobility project signed by NTPC and REL with UT of Ladakh to produce hydrogen in Leh with the help of solar energy of dedicated 1.25 Mw solar power station.

3. National Policy to adopt Coal Gasification

For industrial thermal needs we can substitute by-products of crude oil by-products of crude oil by Coal gas. Now, this is an interesting claim. India has about 300 billion of coal reserves. Our Hon’ Prime Minister has a vision to gasify 100 billion of coal up to 2030. 

If we achieve this target, we can hugely reduce import of crude oil and save India’s substantial amount of foreign currency. Our country strongly requires a national policy to implement Coal Gas as an essential commodity for thermal need of the industry. Today, technologies are available which are clean and pollution-friendly which can be easily implemented to substitute the Coal Gas from oil or natural gas. 

For chemical and fertilizer industry, Syngas made from coal through gasification can be easily used. Sufficient technologies are available and should be implemented. India has taken a small step in this by announcing Talchar Fertilizer Plant to be Coal Gasification based. This is an important and significant step in this direction. 

Coal based power plants results in lot of GHG and there is a way to reduce this factor also. If the power plants are coal gasification based, we can produce syngas in which H2 to CO ration can be more than 2:1. This will tremendously reduce the carbon prints and put India comfortably in line with the Paris accord signed by our Hon’ Prime Minister.

So, to cut the long story short, if India adopts EV, Hydrogen and Coal Gasification as a national policy we can change the Balance of payments 180 degree. It must be a transformation with result-oriented targets. Yes, we can achieve it. Imagine, if you can buy 75 dollars in one Rupee. Let’s get started!!!

Coal Gasification Engineering by CASE Group

It is known to all that coal is cheap and best source of coal gas- a flammable gaseous fuel used for various industrial applications. The process of Coal Gasification is to combust the Coal in a controlled oxygen environment. The resultant is the generation of Coal Gas whose primary constituent is CO instead of CO2. Coal gas is used extensively to replace high value fuels for thermal applications. This Gas can also be used to make fertilizers and Chemicals. 

CASE Group pioneers in 'GASIFICATION' sector. Considering the diverse industrial applications along with economic and environmental constraints, CASE brings a series of coal gasifier types. The gasifiers are primarily used for thermal applications.

Take a snippet of coal gasifier types suitable to meet the users’ demand.

Coal Gasification Engineering

CASE Hot Gasifier: This is the Basic type of Gasifier. This Gasifier Converts Coal into coal gas and the Gas output temperature is over 450ÂșC and the pressure is about 150mmWC

CASE Cold Pyrolysis Gasifier: These Gasifiers are one generation above Hot Gasifiers. In this technology, Gasifier gas can be scrubbed of the TAR and Clean cold Gas can be boosted to any pressure as per user’s requirements. The phenol water is 100% recirculated back into the system. These Gasifiers are fully automatic and are preferably used where burner level Automation is desired like in Automatic Steel Furnaces, Pellet Plants, Glass Plants, Aluminum Calciners etc

Circulating Fluidized Bed Gasifiers: These Gasifiers are the third-generation gasifiers where coal fines of 0mm-10mm size can be used for gasification. The calorific value of gas is about 1300Kcal/Nm3 and can be increased to about 1800Kcal/Nm3 by adding oxygen in the air which is used as gasifying agent.

CASE Entrained Flow Coal Gasifiers: These gasifiers are fourth-Generation Coal Gasifiers where the technology is better than Circulating bed coal gasifiers. In this technology, High ash coal can be used of size less than 100 microns

Clean Gasification Through CFBC Gasifier Route

Circulating Fluidized Bed Gasifiers are third generation gasifiers in the house of CASE Group. In this technology, coal fines of 0mm-10mm size can be used for gasification. 

To mention, the entire gasification is based on ZERO LIQUID DISCHARGE (ZLD). In this case, the volatiles present in the coal are cracked or combusted completely within the gasifier, thus leaving no chance of any Tar or Phenols in the Gas Stream and making it an absolutely clean gasification process.

The CFBC Gasifiers have fluidized bed where coal fines, steam and air are pumped from the bottom to the top. The gas comes out from the top which needs to be filtered and can be compressed to any pressure depending on the user requirements. In this technology, there is no generation of Tar or Phenols.

Coal Gasifier to Transport Gas to Any Distance

CASE brings state-of-the-art gasification technology so as to cater to a number of industrial applications. The Cold Gas Gasification is the latest addition in the product line. In this process, the gas generated from the GASIFIER is made to pass through a series of Gas Purifying and Gas Cooling Sections. The Final Gas is devoid of impurities and Gas temperatures of about 45°C are maintained.

Under such conditions, the final gas is capable to be pressurised through specifically designed compressors. Depending on the distance between the compressor outlet and the utility, the pressure requirements of the burner combustion system and the line losses, the capacity of the compressors can be designed accordingly. With a perfect compressor design a single Coal Gas line can run through the entire plant catering coal gas to various plant utilities.

In this technology, the gasifiers are one generation above the Hot Gasifiers. Gasifier gas can be scrubbed of the TAR and Clean Cold Gas can be boosted to any pressure as per user’s requirements. The phenol water is 100% recirculated back into the system.

Entrained Flow Coal Gasifiers by CASE

CASE, a leading and certified Coal Gasifier Manufacturer offers gasifiers of various types. The state-of-the-art gasifiers are used for different applications. The newly introduced Entrained Flow Gasifiers are Fourth-Generation Coal Gasifiers where the technology is better than Circulating Bed Coal Gasifiers. In this technology, High Ash Coal can be used of size less than 100 microns.

The Gas is filtered and used by the user. The pressure of gas coming out of the gasifier can be plus 80 KPA. In this technology 100% Oxygen can be used instead of air as gasifying agent by which calorific value of plus 2400Kcal/Nm3 can be achieved in the gas. This is a boon where the thermal process requires higher Calorimetric temperatures. 

These gasifiers are down draft in contrast to all the above three cousins. In these gasifiers the temperature is maintained over Ash fusion temperature of coal used. The majority ash comes out in liquid form from the bottom.
