The search for an alternate fuel is not a new venture and many countries have attempted to use methanol in some proportion or other with regular petrol to reduce the cost of petrol which is inherently connected with the day to day living of a human being on earth.
Niti Aayog analyzed the issue in detail and got a report titled “Methanol: A Competitive Alternate Fuel” By Dr. V.K Saraswat1 and Ripunjaya Bansal, reputed economists. Let us learn how to get more mileage and utility value for investment. Reference for report is given at the end of this article.

Methanol: why is methanol a good option as an alternative fuel? Status of methanol in India, pricing of methanol, cost of Domestically produced methanol from coal, vehicular fuel efficiency and emissions 4. Vehicular Fuel Efficiency and Emissions, 5. Comparative Analysis for the cost of Ethanol, Methanol, and gasoline 6.0 Conclusion.
With imports, India meets its requirements for 85% of its crude oil, 53% of its natural gas, and 25% of its coal. Ethanol mixed with various proportions of gasoline reduces the spiraling import bills for crude and relatively cleaner fuel.
India has been giving a push for alternate fuels such as Ethanol and, more recently, Methanol to improve its energy security.
Ethanol is primarily used for blending with gasoline citing twin benefits: substitution of gasoline to arrest rising crude imports and using a relatively cleaner fuel than gasoline.
How is it produced? Is it imported?
Production of ethanol from agriculture is affected in two ways:
Well, it is not clear why does ethanol’s production get anything to do with gasoline products which are highly imported?
Ethanol Blending Program (EBP) has been a priority of the Government, especially since 2014. The National Biofuels Policy of India in 2018 had set a target of 20% blending with gasoline by 2030. The ethanol production increased from 38 Cr liters in 2013-14 to 173 Cr. liters in 2019-20, a jump of 4.5X.
The following progression in its production combined with its blending with gasoline will reveal the progress so far made.
Ethanol Production and Blending %
|Year OMCs 2013-14||Production (Cr Liter) 38.0||Blending %age PSU 1.53%|
It may be observed from above data that with a mere production of 38.0 crores of liters in 2013-14, we have reached 173.00 cr. Liters of ethanol with blending % age of 5.00%. By 2025-26, the ethanol production may reach 1016 liters for a blending ratio of 20%.
It may be of interest to know that Until FY 18, C-Heavy molasses was the primary source of feedstock for ethanol production, however, since FY 19, different kinds of raw materials such as B-Heavy molasses, sugarcane juice and damaged food grains have been used as well to produce ethanol.
Let us learn who fixes the price of ethanol.
The pricing also depends the production of ethanol and steps taken by the government to increase its production.
The government has taken the following steps:
By having a consistent policy to increase the production of ethanol by 8X since 2013-14, the government has shown its intention to reduce the imports and add it with gasoline.
To obviate the timely payment of sugarcane to agriculturists, the government is encouraging the production of more ethanol through the diversion of 6 MT of sugar by 2025.
Kindly refer to table 2.4 on page 12 of the report. The following facts have been collected from there.
“Table 2.4 shows the likely tax loss to the central government incurred due to the gasoline replaced by ethanol for ethanol blending with gasoline. The likely amount comes out to be INR 4757 Cr for 2019-20. The tax loss will increase in the future as the government has a target of 20% ethanol blending by 2025. The amount can increase to more than 5 times as the ethanol production has to be increased to 1000 Cr. Liters by 2025 from 173 Cr. Liters in 2019-20.”
However, it must be noted that to reach the goal of 20% blending of ethanol with gasoline, the government must prepare for this tax loss so that import substitute can be developed over a period.
Why methanol blending with gasoline is needed urgently and what are the major benefits to the economy? Has any- one used it before and got enormous benefits so that India can venture into production of methanol and immensely gain by blending it with gasoline?
Let us break our arguments in parts.
So far, we haven’t used blending of methanol with gasoline though the success story of China with its phenomenal performance is part of folklore of the world.
Let us get illumined with its current success.
China has successfully commercialized the coal to methanol projects and is the world’s largest producer and consumer of Methanol. China has developed a huge MTX industry i.e., a methanol- based platform where methanol is converted to olefins, gasoline, aromatics, dimethyl-ether, and methyl tertiary butyl ether. The large number of Coal to X plants in China not only enhances its energy security but also opens avenues for chemical and petrochemical sectors where methanol is a major feedstock.
It is of interest to know that in 2016, China blended around 21 MT of methanol with gasoline, whereas India has not even started using methanol as a transportation fuel. 15 provinces of China are already using different Methanol blends (M15 to M100) as transportation fuel and the trend is likely to grow.
Exactly, where do we stand?
The Methanol imports have grown at a CAGR of 5.4% and the import value is to the tune of $700 Million in 2018-19. Therefore, domestic production of methanol derived from coal will eliminate import of methanol.
Let us look at methanol’s price over the last two decades.
Domestic Methanol Prices (INR/Kg)
2009-2010 – 20.1, 2013-14 – 41.8, 2019-20 – 26.7.
Why there is variation in prices which are sometimes very volatile?
Since 90% of methanol requirement in India is met through imports, domestic production becomes viable only when the import prices are high enough to support the high cost of domestically produced methanol from natural gas.
The high cost of methanol production is attributed to a high cost of feedstock, which is natural gas. RLNG is primarily used to produce methanol which is not below $8-10/mmbtu by the time gas reaches the plant gate.
However, based on the internal research done by the Ministry of Coal in collaboration with other experts, the price of methanol is likely to hover around INR 22-25/Kg22 or INR 17.5 – 19.8 per liter (density of methanol – 0.791 kg/liter). So far, we haven’t got any plant to produce methanol from coal.
Why coal is aligned with methanol whenever we talk of its production here?
Let us go back to page 15 of the report and read the argument given for gasifying coal in India.
Why to use coal for production of methanol?
Abundant proven reserves of 155 BT& a RP ration of 140 years.
Then coal to chemicals, petrochemicals, fertilizers etc.
Many high valued products can be produced through coal gasification process like methanol, DME, Olefins, Ammonia, Acetic acid etc.
Methanol can be easily blended with gasoline and not many changes required for M15. DME can be blended with LPG and it is known that methanol helps to produce DME.
Import of olefins, formaldehyde and others can be avoided by producing methanol.
What are the environmental considerations for a highly polluted nation like ours?
Coal gasification emits less than coal combustion. Things obtained from methanol like olefins or formaldehyde are clean.
To give as an incentive, in future commercial coal block auctions, there is a provision for 20% rebate in revenue share provided the mine developer uses at least 10% of its production for coal gasification.
Let us compare the production cost of ethanol vis-à-vis methanol.
1.28 liters of methanol will cost INR 25.3, whereas the same amount of energy is available for INR 45.69 – 62.65 in case of ethanol.
It is pleasing to learn that with regards to emissions, the methanol gasoline blends have the lowest hydrocarbon (HC) and carbon monoxide (CO) emissions when compared with ethanol gasoline blends or methanol ethanol-gasoline blends.
Our detailed analysis of ethanol, methanol, various ways of production of these alternate fuels and the reasons to venture into these particularly in case of methanol where no coalification plants set up so far lead us to the following conclusion:
Why not compare us with China and travel new routes for import substitution of gasoline?
Urgent time bound program is a must.
