Bye Bye Diesel Petrol, Welcome Biofuel- Global Biofuel Alliance- A paradigm shift in sustainable energy, Carbon foot print and economic strategy- various options before India

Petrol engine was invented by Nicolaus August Otto of Germany in 1876 and Diesel engine by Rudolf Diesel in 1897.

Today, even after 150.years, the IC engine technology is still alive although with a lot of cosmetic upgrades such as Euro-1/2/3/4/5/6… & so on. Can we think of life without Automobiles ?

Even today , when we are talking of Bio fuel , Ethanol, Green Methanol , Ammonia , Bio-diesel , CNG, Green Hydrogen, the IC Engine would still continue to be there for years to come, the world owes to the inventors.

However, these Gas guzzlers with diesel petrol as fuel are the the main source of air pollution with toxic exhaust gases and most importantly carbon emissions which is systematically leading to Global warming and climate change which the planet earth is facing at a rapid rate.

Now that the entire world is focussing to resolve this issue, IEA says - World at
"begining of end " of fossil fuel era.

But India has another issue at hand - we had to import 87% of our crude requirement in 2022-23 of 232 MMT worth 16 Lakh crore. our indigenous production was a miniscule 28MT- we just meet 13% of our requirement.
Similarly , we had to import 50% of our CNG / LNG requirement in 2022-23.

India is not an oil rich country like Gulf / Russia/ USA. Two of our upstream Gas & Oil companies like ONGC and Oil India have been working on Oil & Gas exploration since last more than 60 years. The Govt has also opened Pvt Sectors for oil & Gas exploration & Reliance , BP are jointly working on exploration of Oil & Gas …recently Govt has allowed 100% FDI in Oil & Gas exploration, but the needle has moved very little.
Basically, we have been trying to squeeze dry towel to get water. So we have very little OIL & GAS.
However, Nature has been very kind to us.We are Blessed with adequate SUN light, Wind, Water, Rain and most importantly we have Vast Arable land with 169 million ha. India closely followed by the United States of America (160 million ha), China (136 million ha), the Russian Federation (123 million ha) and Brazil (64 million ha).

India is World’s most youngest & populous nation full of Human talents. We can send a rocket and land in the moon where no one has landed. Can we not make best use of what we have ?

India is the 3rd largest importer of crude in the world and the energy requirement is increasing @ 9% annually. Energy security is something which India is very much concerned with a lot of volatility of crude oil and uncertainty in supplies due to Geo- political situation and that is the reason the Govt is trying to come out with alternatives such as Ethanol, Bio gas, Bio- Diesel, Flex fuel , Green Hydrogen, EV with a view to become "Atma Nirbhar Bharat ".
With so much of noise on Biofuel, currently we are not even one among top 5 Biofuel producing nations in the world ( USA, Brazil, China, Indonesia, Germany ), though we have all the ingredients , drive ,& need to become no.1 Biofuel nation.

The recent Biofuel Global Alliance conceived by India and supported by the entire world is the right step to counter our Duel challenges of Carbon emissions and the burgeoning Import bill & energy security.

As I had done some work with Auto Industry and with reference to Auto emission, created this thread to familiarise with various options that we have in India to become Atma Nirbhar Bharat as far as Automobile fuel is concerned. We may like to identify stocks / companies which we can think of investing from medium to long term point of view.

(1) Diesel / Petrol
Pros : Familiar technology, Affordable price , easy to service , we are most comfortable with

Cons : Carbon emissions 8 to 16 times higher than CNG fuel. Highly polluting with , NOx, HC, SPM, RSPM , Climate change, Global warming,
Import dependence, forex outgo, Uncertainty in supply, price fluctuation in international market and geo political situation

(2) CNG
Pros : 8-16 times less carbon emissions than petrol diesel. clean fuel in use since 2001. Estimated 8 millions CNG vehicles of all types in Indian road includes CNG retrofitted kits.

companies involved - Maruti , Tata Motors, Leyland , Volvo Eicher, Mahindra , Bajaj 3 wheeler, Atul auto 3 wheelers - All OEM’s sell CNG models. Cummins has exclusive CNG engines for heavy vehicles. one Minda group co deals with CNG kits for OEM. CNG cylinder manufacturers.
others in the CNG business are CGD’s such as IGL, Gujarat Gas, MGL, Adani , Gail, Petronet LNG, Torrent , GAIL

Not a renewable fuel. Import dependence.
CNG filling stations are limited to Northern & Western India- HBJ pipeline. Now pipelines are under construction in East and South India.

Heavy vehicles can run up to 500 kms Max at one fill and cars can run up to 100-200 kms …so not suitable for long journeys since refills can only be done within city limits. outside city limits , filling stations may not be there.

(3) LNG

Pros : Liquified form of CNG can be filled in cryogenic tanks for long haul drive more suitable for heavy trucks for long distance drive . Engine same as CNG. Other benefits same as CNG

Cons - Not a renewable energy. import dependency.

companies involved : same as that of CNG

(4) Bio-Ethanol-1G from Sugarcane/corn/ grains

Pros : Though Ethanol has two carbon atoms and so there is two times more carbon emissions than CNG, its carbon dioxide gets absorbed by sugar cane plants which would be grown throughout the year. so it is considered as Renewable fuel with zero carbon foot print. less pollution. India has vast agriculture land. Sugarcane farmers earn money so also sugar cane companies. No import dependency.
Atma nirbhar Bharat

Can be mixed with petrol in varying proportions. currently we are at 12% at all India level …aiming to 20% blend by 2025 and save Rs 1,00,000 crore per annum. in fact some of the filling station have already started dispensing 20% ethanol.
Cons :
Inadequate production capacities currently. Flexi fuel capability yet to be developed by OEM’s

Companies- All sugar manufacturing stocks/ Ethanol producers / Ethanol plants manufacturers such as Praj. All OMC - PSU are actively involved. All Auto OEM’s.

(5) Bio-Ethanol 2-G from crops/ vegetables biomass residues , straw , bamboo, stubble.

Pros-same as 1- G ethanol
Cons: Supply chain of feedstock and inadequate establishment / investment

Companies : Oil PSU’s like Indian oil & oil India and others are installing Bio-Ethanol 2G in their refineries.
Praj supplies 2G ethanol plant.

(6) CBG- Compressed Bio gas also known as Bio- CNG
Produced from Bio waste such as crops/ vegetable waste / residues, straw , cow dung , kitchen waste and any type of Agri waste/ Agri- Biomass.

Pros :
Same as CNG. Property of CBG same as that of CNG. But it is renewable energy. No import dependency. Atma nirbhar Bharat. Govt subsidy available under SATAT Scheme (Sustainable Alternative Towards Affordable Transportation) is an initiative by the government of India with the objective of setting up Compressed Biogas production plants, and make it available for market use for automotives.
Maruti Suzuki has entered in to agreement in Gujarat milk federation for cow dung feedstock to produce Biogas. Reliance and Adani is entering in to Bio gas business in a big way.

Praj , Thermax makes Biogas plants .

Other companies involved are same as CNG.

Cons: Eco system for Feed stock gathering / collecting / supply chain not well developed though it is estimated by Bio Gas association that India has plenty of Biomass to produce 170000 MT of CBG/ day can be produced which can meet one third of crude import or can meet the entire LNG import…

(7) LBG or Bio LNG
properties same as LNG. But Bio LNG or LBG is renewable energy. as it can be produced from BCG… no import dependency.
All other pros and cons are same as
non-renewable LNG/ CNG

(8) Flex fuel :
Brazilian flexible-fuel vehicles are optimized to run on any mix of E20-E25 gasoline and up to 100% hydrous ethanol fuel (E100). Flex vehicles in Brazil are built-in with a small gasoline reservoir for cold starting the engine when temperatures drop below 15 °C (59 °F).
Brazil Has Over 34 Million Licensed Vehicles, One of the Largest Flex-Fuel Fleets in the World.

If Brazil can do a massive sugar cane cultivation & ethanol production with just 60 million ha Land mass - why not we with 160 million ha Land ???

(9) Green hydrogen can also be produced from CBG ( Methane).
The process of production of hydrogen from CBG is same as that for hydrogen from Natural gas currently followed at Fertiliser plants.
Green hydrogen in turn can be used as ultimate Green fuel for automobiles IC engine . Fuel cell is ideal but expensive.
More on green hydrogen can be found in green hydrogen thread

(8) Green Hydrogen produced from electrolysis of water can be dispensed through hydrogen filling stations. Hydrogen cars with good old IC engine. zero carbon emissions.
For details you may please see green hydrogen thread.
Atma nirbhar Bharat.

(9) Methanol/ Bio methanol/ Green Methanol- It is the 1st.member of alcohol family with one carbon atom.

Pros : Cheapest to produce. China is the leader in the world production and as auto fuel.
it can be produced by 3 methods:
From (a)Coal
(b)From Methane,/ CNG/ CBG
(c) From CO2 and Green Hydrogen

If methanol is produced from CBG as in (b)above, it is called Bio methanol
. it is renewable energy. The method (c) is also renewable if it is green hydrogen , but expensive though…

(10) Bio Diesel : Produced from non- edible oil / burnt used oil by reaction with either Bio Methanol or Bio- ethanol.
Pros : considered renewable as non edible crops are grown which absorb CO2.

Currently : The oil PSU’s are procuring Biodiesel and mixing with diesel.
There is only one listed company named Kotyark Industries Limited which makes bio diesel. There are dozens of unlisted players out of which Emami agrotech of Emami group is worth mentioning which exports biodiesel to Europe.

pros: Atma nirbhar Bharat …no import dependency … Many transport operators / STU are already using this.

Cons: Lack of ecosystem supply chain for feedstock. so scalability is an issue.
There has to be clear govt policy on non edible crops cultivation such as Jatropha, karanajia, mahua, castor,cotton, rubber, palm etc.

(11) EV -
Pros: Zero carbon emissions at tail pipe.

Cons: Expensive ! penetration remains low.
Currently Li Battery is imported from China Korea. Govt has approved Battery PLI for 4 players - Reliance , Hyundai Global , Ola & Rajesh export. Exide and Amara Raja battery was rejected. Perhaps Govt wanted Green field project …not brown field.So both Exide & Amara Raja are going to make EV Li Battery on their own investment without PLI.
Even if these companies make batteries in India , still they have to import Li, cobalt , nickel from Argentina & Australlia.

It is not Atma nirbhar Bharat.

The Govt initiated FAME -1 subsidy in 2015 , FAME-2 in 2019. But recently Govt reduced FAME 2 subsidy and the 2-wheeler sales nosedived in July - August. Now , Govt seems to be planning for FAME-3 ! How long an industry can survive only on Govt subsidy??The OEMs should do their bit , their own research development plan to reduce cost !

Very Few individual pvt operators can buy a EV bus or truck…though EV cars/2 wheelers may be affordable to some extent.

Maruti rightly said they are not yet ready with an EV for their mass market customers at a price the customer can afford. Maruti is betting Big in CNG- currently producing 7 lakh CNG vehicles per annum.They have phased out Diesel completely. Every new model they release to the market has a CNG twin. No wonder, Suzuki Motors coming up in a big way to produce CBG- renewable form of CNG by collaboration with milk federations in Gujarat for CBG from cow dung

Alternate Battery technology to be developed and made available at cheaper rate with indigenous material to make EV affordable for Atma nirbhar Bharat.

Battery charging done through Thermal power source … so it is not carbon neutral.

However , EV can grow at its own pace.

Price approx of different Bio fuels vs diesel petrol as on date as follows . However price can still be lower if scalability and sound supply chain.

All in INR per litre
Diesel- 92
Petrol -105
CNG- 80
Bio-Ethanol- 65
CBG- 45
Methanol-20 to 40 ,(from coal)

The Govt intentions are good. But execution remains slow. Further the Govt requires quick response & support from industry, MSME’s which currently seems to be sluggish.

who are the methanol/green methanol producers in india ?


China is leading the world methanol market with 60% market share.
There are many in listed / unlisted space in india - But not green …they are either producing my coal or natural gas…

Apart from being a clean-burning fuel used as an alternative for gasoline in automobiles , methanol has many other industrial uses:

  • industrial solvent for dyes, inks, resins, fragrances, cosmetics.
  • in the Pharma, for production of hormones, vitamins, cholesterol
  • It is also very valuable as an antifreeze in pipelines.
  • Lastly, methanol is used in the chemical synthesis of DME dimethyl ether

Companies involved in Methanol though not Green methanol are : Vinati organics, Gujarat Narmada Valley Fertilizer & Chemicals limited, Deepak Fertilizers, Rashtriya Chemicals and Fertilizers, Assam Petrochemicals and National Fertilizers Limited, Gujarat Alkalis limited

However, NTPC is seriously working on the Green methanol projects. it is setting up Green methanol plants at all it’s thermal plants The plan is to capture CO2 from thermal power plant and convert it to methanol with help of green hydrogen.

The adoption and development of EVs may be much faster than what we assume. The way industry biggies are focussing on the theme there ia every possibility of battery prices correcting by over 50%. This is major hursle overcome.
We have seen new lithium discoveries which will be operational over 5_6 years. The adoption will be in line with growth in solar power production, which has now become, arguably, cheapest. Although land requirement may be next big hurdle.
Development in EV space from here on will be on faster mode, and economical. The infrastructure scale up in EU will lead followed by othera.
Govt across globe will come out with policies favourable for sector.
World is changing fast, and deapite all negatives of cost ans infrastructure the segment is galloping. So the consumer preference is tilted towards this, and the moment its cost is viable switch will be complete. I think pwople will not mind paying 10-15% extra foe an EV.

Except breakthrough in Hydrogen Fuel Cell, EV will lwad the transition.

Methanol will rwmain industrial solvent for years to come. I dont think its a viable proposition.

We have to see how the technology evolves and how fast the Auto industry responses.

However, Two major factors which could influence Govt decision and force Industry to adopt technology (1) Sustainability with refrence to carbon footprint (2) Atma Nirbhar Bharat

When we import something , the price we have to pay for imports is decided by the seller nation and that would depend upon many factors such as demand -supply, the cost of production of that item in that country and Geo political situations.

Look at what happened recently to Semiconductors - it crippled the auto industry.
& the pharma industry where our pharma companies / Speciality chemicals import most critical API’s and / the KRM ( key raw material) from China and China plays their card whatever way they want- raise price for key raw material to Indian buyers and dump finished products at other countries.

And Look at crude oil price , it was 20-30 USD per barrel a couple of years back…And today hovering around 95 USD.

EV may evolve at its own pace depending upon the Govt subsidy which they started in 2015 with FAME1 and in 2019- FAME 2 which now they have withdrawn and the industry response.

However, if our discovery of lithium mines in J&K comes true , it would be beneficial…But we have to see what is the extent reserve and then mining refining also calls for investments.

But we still have to import cobalt and nickel.
Alternatively , if the technology evolves with low cost Sodium ion battery which Reliance trying to do could also be a game changer for EV.

Moreover , A very recent IIT kanpur study indicates that EV has more carbon foot print / emissions than Hybrid and conventional petrol diesel engines- is something an area of concern which the western world is also taking seriously. While details of the study is available in public domain, an article which describes in brief is given below for our understanding.

The study compared the emissions of EVs, Hybrids, and conventional petrol cars throughout their lifecycle, including production, maintenance, and recycling. Results revealed that EVs emit 187 grams of carbon dioxide per kilometer (gCO eq./km), while hybrids emit 167 gCO eq./km. In contrast, regular petrol cars emit 244 gCO eq./km. The cars used for the analysis focused on the petrol and electric variants of the Tata Nexon and Maruti Suzuki’s hybrid Grand Vitara.

So, Is Hybrid the future for India ? only time could tell. But going by the technology , it is great for India because of following reasons.
(1) No need for charging battery …no plug … No need for any power
(2) No range issue
(3) Battery- minimal import dependence …Lead acid battery can also be used.
(4) Regenerative braking is used to generate electricity and charge battery and run engine
(5) Milage better than EV because brake energy don’t go waste .
(6) What is most important is the engine can run on Petrol Ethanol blend up to 20% and later the engine can run with flex fuel up to 100% ethanol with technology upgradation. Brazil already has 34 million flex vehicles.

So , Who moved my Cheese ???
Guess what , gradually the Hybrids EV cars are increasing than pure EV’s. and the hybrid numbers sold during oct 2022 to May 2023 equals Pure EV play.

Industry sales data shows that automobile makers sold 48,424 units of strong hybrid cars in the domestic market between October 2022 and May 2023, just about 600 units fewer than the 48,991 electric cars sold during the same period.

Maruti came out with mutual collaboration arrangement with Toyota to source their Hybrid technology and sell at a price to mass customers who in turn find it convenient and affordable than EV.
Maruti 's strategy is working out well. This is in spite of the fact that Hybrids GST taxed @ 43% against 5% on EV. So Hybrid carries no subsidy because of its petrol engine platform.

The research also revealed that the total Cost of Ownership (TCO) per kilometer for EVs and petrol-powered vehicles is approximately ₹13, while it stands at ₹14 for hybrids. However, when considering government subsidies for EVs, the TCO for hybrids falls to just ₹11 per kilometer. It stated that if hybrids receive similar incentives in the future, they could become the most cost-effective option.

The Govt has realised that Hybrids can run on ethanol and they may give similar subsidy to Hybrids or they even may lower subsidy on EV, if the industry does not respond with lower cost of production. And recently the minister has unveiled one 100% Ethanol hybrid…

After all Maruti is Maruti. They enjoy their leadership in the country in terms of car numbers and for their quality & service network for the last 38 years.
They are in a better position to quickly upgrade their Hybrid from petrol to ethanol and CNG to CBG.
Attaching few relevant news articles - good read

Hybrid car sales are catching up with that of electric vehicles in India — more affordable, resale value


Lot of fertilizer plants are going to produce ethanol in the future.

Brazil offers Ethanol technology to India

Global Biofuel Alliance initiatives yet to take shape. In the mean time , Brazil and India agreed to settle their long standing Dispute on Sugar pricing and subsidies at WTO and Brazil in turn has agreed to give the Ethanol technology.
Both the countries are the world’s top 2 producers of Sugar.The Global Sugar price is determined by both countries.

Brazil seems to have agreed to give the Ethanol technology, which India badly needs if India has to go beyond 20% blending and fiex fuel technology upto 100% ethanol car which Brazil is already producing.
Brazil is also blending 12% Bio diesel with Diesel.

India has started a pilot study adding Ethanol in diesel.
Ethanol Petrol both blend well up to 25-30% without requiring any major engine modification.
However, Ethanol Diesel don’t mix well and you need a emulsifier like methyl ester or any such binder which has oxygen in it or oxygenates.

Some of the 2 wheeler OEM’ have already made a back door entry in to CNG through after market retro fitment. There are after market CNG retro kits available for 2 wheelers in the market place at a cost of Rs20,000 supplied by an Italian company Lendy Ranzo in name of Lovato brand.
These kits have been approved by ARAI , Pune and also got approval from respective OEM’s for retrofitment.
The CNG kit for two wheelers comprises of two CNG cylinders of 1.2 kg each, which can run up to 120 to 130 km per kg at an approximate cost of Rs 0.60 per km per single fill.

There is a pilot batch of Honda Activa Running with retro CNG kits in Delhi since last few years by Zomato food delivery.

  1. Yes
  2. Yes
  3. Hybrids cannot and do not use lead acid batteries, batteries used in hybrids like Toyota Innova Hycross are Nickel–metal hydride battery, whose cells need to be imported.
  4. Regenerative braking is available in EVs too, it is not exclusive to hybrids!
  5. Point (4) and (5) are same.
  6. No, later the same engine cannot run on 100% ethanol, ethanol is corrosive and the fuel lines etc need to be changed, also ethanol significantly reduces the longevity of engines.

Maruti is flexing the government policies, these facts and studies are twisted, most of the studies are not objective. It is because of Maruti GoI took a u-turn on mandatory 6 airbags policy. Such is the power of Maruti.

Maruti Hybrid do have a dual battery system - one Lead acid battery and only a smaller lithium ion battery and therefore minimising requirement of expensive lithium, cobalt , nickel.
You may like to go through this link of Maruti web site.
Regenerative braking , yes I agree EV 's also have . But it finally it boils down to (1) total life cycle carbon foot print EV vs Hybrid and that Hybrid is having the advantage of not using any thermal electricity for recharging.(2) TCO- total cost of ownership per km.

When we say Ethanol in Indian context , we would always mean blended Ethanol for the time being as we have already achieved 12% blending and aiming to reach 20% by 2025 without any major engine modification . To that extent we would reduce import dependence. 100% ethanol , flexi fuel Engine would require major engine modification- but the basic IC engine remains the same. Therefore , the manufacturer has to upgrade the same Engine platform , though it may not be feasible to modify existing engines, but retrofitment of ethanol engine may be feasible at a later date.

Maruti Hybrids has a petrol engine which could run on ethanol blend- which of date 100% oil outlets dispenses only blended

There is no denying that the Indian customers have accepted hybrids in equal numbers vs EV in Car segment (without any govt subsidy on hybrids). And tomorrow , if the govt cuts
GST on ethanol hybrids, it may force industries to adopt ethanol technology and encourage atma nirbhar Bharat.
Brazil has millions of hybrids running with flex fuel / ethanol. So ethanol technology can not be challenged. Yes , to switch to 100% ethanol and fiex fuel , right now we may not have the right technology except Toyota- though Maruti has collaboration agreement with Toyota , the maker of hybrids with 100% ethanol.
But industries as a whole need to develop technology for 100% ethanol .

We can always accept or reject a study done by a premier institute, but we can not challenge the ground reality in Indian context and we will have to see how the technology evolves in a country like ours where we would have to depend upon imports which leads to supply chain disruptions depending upon geopolitical situations and volatility in price of imports and the fact remains that to make EV sustainable for long term in Indian context , the industries need to innovate , reduce cost , Recycle the Lithium cobalt nickel to the max extent possible and find out alternative to Lithium cobalt nickel and most importantly don’t depend upon Govt subsidy ,( FAME 1/ FAME 2/ FAME 3 and so on.

Govt recently withdrawn FAME 2 only to force industry to Innovate and reduce cost which is unfortunately not happening since FAME 1 , 2015.

As technologies evolve we will have a mix of EV, Hybrids, Ethanol/Ethanol Hybrids, CBG, CNG/LNG, Hydrogen could co-exists together for quite some time and share of petrol diesel would come down gradually.
Finally, It is Green hydrogen and Fuel cell which would take over.

Difference between a Hybrid battery vs EV battery- well explained !

Please read the full article to have better insights The article written sometime back does not even mention about the use of ethanol petrol blends , which is an import substitution to the extent of ethanol % in petrol which is currently 12-20% technology can be extended to 100% ethanol / flex fuel - future potential to replace petrol totally with ethanol.

As per this article, even if you you use 100% petrol ( don’t use ethanol blends) , still the Hybrid saves 50% fuel when compared with pure petrol engine and to that extent petrol imports gets reduced… whether to reduce in petrol imports in pure hybrids vs spend upon Li battery /rare earth elements imports in EV ?
You get 50% fuel savings in Hybrid for 5% of the rare earths that a pure EV needs ( Hybrids battery capacities being smaller, need only 5% of rare element than that of a EV battery). So do you extract 40 times more rare earths or save only 50% of the fuel?

the govt subsidy burden for EV is an additional expense.


Heavy demand of lithium ion battery for BESS( Battery Energy storage solution) could put further pressure on availability of EV Batteries.

Govt launches registration portal for Biogas plants

This is an excellent initiative by Govt. These registered unit will be given financial assistance.
In the
GOBARdhan aims to transform biodegradable and organic waste, including cattle dung, agricultural residues, and biomass, into high-value resources such as Biogas/ CBG and the bye- product is guess what ? it is organic manure which can be utilised for growing food crops. So you will get only organic vegetables and fruits to eat and ensure that you are at sound health. Do Bye-Bye to inorganic fertiliser chemicals like SSP, DAP, urea etc.
And during last 2 budgets , the govt had already announced subsidy for producing organic fertilisers. So now , Organic fertilisers from BCG is very much in alignment with this new announcement.

It is worth mentioning that CBG is a renewable energy , it is nothing but methane can be used in any CNG vehicles which are growing at a faster rate.
Moreover , CBG can also be Liquified to LBG. LBG is Liquified Biogas which is similar to LNG.
What is special with LNG/LBG ? LNG can be carried in LNG tanks like petrol diesel tanks and can be used in long haul trucks which can cover 1000’s of kms without refill and the engine is same as that of CNG

Bio Fuel is great for environment but I am a little skeptical that it could be done at present. The entire auto industry has already invested a lot in EV. It might take 4-5 years for this shift from petrol to biofuel in my opinion.

Today, 85% vehicles being produced in india are still petrol diesel 12 % may be CNG and 2-3% may be EV.
it makes sense and it is logical.that if we can run these existing IC engine vehicles with blend of renewable Bio fuels such as Ethanol, Bio diesel & CBG In place of CNG to the maximum extent possible without any engine modification. though for flex fuel hybrids some engine modification would be required (on the same platform of IC engine without major expensive alterations )

It is not a transition that is going to take place all of a sudden…EV will co-exist together Along with biofuels . EV is expensive to own and everyone can not afford to buy EV without Govt subsidy, It also has an import content of rare earth elements, And the recent life cycle study on carbon foot print indicates no appreciable improvement in carbon emissions.

It is not only for Environment which is primarily a Global issue and India is a part of it. Most importantly India aims to reduce its import dependency on diesel petrol which is currently stands at 90% of our requirement and that too uncertainty of availability due to Geo-political situations all the time and price volatility.

Therefore my take is that Bio fuels such as Bio-Ethanol 1G/2G, CBG/LBG, CNG/LNG all will coexists together along with EV for quite some time.

Our import dependency on diesel petrol will gradually come down.

Is there any indication/publically available data related carbon footprints(Scope1,2,3 emission of GHG) of EV vis a vis flex fuel hybrids ?

If flex fuel hybrids have lesser carbon foot prints compared to EV, that may be the obvious choice provided the refueling infrastructure is already available.

Based on my understanding/experience I would like to agree that in longer term dependency on petrol/diesel may indeed come down.
