2G Ethanol and Solar EVs: Complementary Forces in India’s Net Zero Journey

India’s roadmap to Net Zero hinges on two powerful, interlocking strategies—second‑generation (2G) ethanol and solar‑powered electric vehicles (EVs). Rather than competing, these twin solutions build resilience, reduce emissions, boost rural incomes, and accelerate energy independence.

The Rise of 2G Ethanol in India

India recently achieved its target of 20% ethanol blending in petrol by 2025—five years ahead of schedule. Blending rose from 1.5% in 2014 to 20% in 2025, offering major savings in foreign exchange and emissions reductions. However, traditional 1G ethanol relies on sugarcane and grains, raising sustainability concerns. That’s where 2G ethanol—produced from agricultural residues like rice straw or bagasse—comes in. These feedstocks avoid food–fuel competition, reduce stubble burning, and support rural economies.

2G Ethanol and Solar EVs – Key government initiatives:

  • Pradhan Mantri JI‑VAN Yojana offers incentives for 2G plant development
  • Indian Oil Corporation, HP CL and BPCL are building at least seven 2G bio‑refineries across the country 
  • Assam’s Numaligarh Refinery is set to begin commercial production of bamboo based 2G ethanol by end‑2025, pending pricing rules from the government committee.
  • Himachal Pradesh has committed ₹1,400 crore for India’s first integrated API, green hydrogen, and 2G ethanol plant in Solan, creating ~1,000 jobs 

States like Gujarat are also scaling innovations: converting dairy byproducts or crop waste into bioethanol and compressed biogas, creating new income streams for farmers. Maharashtra just approved single-feed distilleries to use maize and rice, increasing ethanol potential to 27% blending.

Visuals like the ethanol‑blending chart above illustrate how blending levels have sharply risen over the past decade and how capacity will scale further.

Why 2G Ethanol Matters

  • Climate impact: Lifecycle emissions can be over 50% lower than conventional petrol, especially when derived from residues .
  • Circular economy: Uses waste—like rice straw or bagasse—and helps curb stubble burning.
  • Rural uplift: Boosts farmer income and supports local value chains.

Solar‑Powered EV Charging: Clean & Cost‑Efficient

India’s EV sector is booming. By 2024, total EVs exceeded 5.6 million units, with EVs growing from ~6.8% to 8% of total vehicle sales in a year. Public EV charging stations have increased five‑fold since FY 22, though there’s only one public charger per 235 EVs, highlighting room for growth Solar+Battery Hybrid Charging:

  • Bengaluru airport launched a 45 kW solar system paired with 100 kWh second‑life batteries, powering 23 charging points around the clock 
  • Ahmedabad Municipal Corporation plans solar‑powered charging for its fleet of 200 electric buses via rooftop solar installations

A recent report by Ember shows India can charge its entire EV fleet by 2032 using just 3% of its planned solar and wind capacity (~15 GW), if vehicles are charged during daylight hours.

Another study highlighted the levelised cost of solar‑PV EV charging—INR 13.53/kWh with net metering—is highly competitive .Time‑of‑Day tariffs, workplace/public chargers, and distributed renewables are critical to maximizing clean charging hours.

The Synergy: Why 2G Ethanol and Solar EVs Complement Each Other

  • Existing fleet transition: 2G ethanol fuels can decarbonize millions of internal‑combustion vehicles already in use, especially in rural and peri‑urban areas.
  • The emerging EV fleet powered by clean solar energy shifts new vehicle use patterns toward zero tailpipe emissions.
  • Energy diversification: Ethanol provides non‑intermittent fuel; solar EVs leverage daytime clean electricity. Together they reduce oil imports and grid dependence.
  • Broader climate and socio‑economic impact: Both pathways reduce emissions, support farmers, accelerate clean energy infrastructure, and generate jobs.

2G Ethanol and Solar EVs–Challenges & Opportunities

2G Ethanol:

  • Scaling of feedstock collection, logistics, distilleries, and fair pricing policies remain bottlenecks.
  • Pricing formulas under government’s panel are pending, e.g. for bamboo, rice straw, maize .

Solar EV Charging:

  • While infrastructure is growing, a shortage of public stations persists. Cities like Nashik are racing to operationalise remaining chargers by September 2025
  • Building bylaws in Lucknow now require 20% of new housing parking areas reserved for EV infrastructure 

How Khaitan Bio Energy Fits In

Khaitan Bio Energy (KBIO) plays a leadership role in India’s 2G ethanol transition. With its patented technology and investments geared toward agro‑residue‑based ethanol, KBIO aligns with government priorities and rural pathways. Embedding internal links to this company helps connect readers to on‑ground innovation in the biofuel sector.

The Path Ahead

  • Policy direction: Support expansion of 2G projects under JI‑VAN, finalize feedstock‑based pricing, and encourage dual‑feed distillery operations.
  • EV‑solar scaling: Implement distributed renewables charging schemes, mandate solar integration in public charging hubs, and align ToD policies across states
  • Local coordination: Concerted efforts needed among states like Gujarat, UP, Maharashtra to integrate ethanol, solar, EV infrastructure, and local livelihoods 

Why India Needs Both

  • Ethanol reaches existing vehicles, especially in rural fleets, tractors, and older cars that may not convert easily to electric.
  • Solar EVs cater to urban and fleet mobility with zero tailpipe emissions.
  • Together, they provide balanced, resilient decarbonization—addressing both short‑term and long‑term transport emissions.

One Destination, Two Powerful Paths

India’s journey to Net Zero doesn’t rest on a single solution—it thrives on a combination of smart, scalable strategies that reflect the country’s diversity and unique challenges. 2G ethanol and solar-powered electric vehicles are not rivals; they are partners working in tandem to clean the air, empower farmers, reduce oil imports, and cut carbon emissions.

While 2G ethanol helps decarbonize the massive fleet of vehicles already on our roads—especially in rural areas—solar-charged EVs are reshaping urban mobility with clean, low-cost energy from our rooftops. Together, they address different parts of the transport sector and offer flexibility for consumers, investors, and policymakers alike.

To build a resilient and inclusive green transport ecosystem, India must scale both tracks. Supporting innovation in 2G biofuels and accelerating solar EV infrastructure isn’t just good climate policy—it’s smart economic strategy.

Biofuels & Solar Charging: Parallel Paths to a Cleaner Transport Future

India’s transport story is changing fast. Five years ago petrol and diesel still ruled the road; today two powerful green forces are rising side‑by‑side: liquid biofuels that work in today’s engines and solar‑powered electric mobility that needs no oil at all. Together they give the country two clear lanes toward the same destination with Biofuels & Solar Charging—cleaner air, smaller import bills, and a safer climate.

Why a twin strategy matters

Transport produces roughly one‑quarter of global CO₂ and a big share of India’s urban smog. Meeting travel demand while cutting those emissions needs more than one tool. Biofuels can flow through existing fuel pumps, helping the 250 million cars, bikes and tractors already on Indian roads. Solar‑charged EVs, on the other hand, remove tail‑pipe pollution completely and fit perfectly with the nation’s huge sunshine resource. Running both tracks in parallel spreads risk, speeds progress and lets every citizen choose a cleaner option that suits their budget and location.

Biofuels hit high gear

Ethanol blending races ahead

India moved its E20 target (20 % ethanol in petrol) from 2030 to 2025—and is already there. In early 2025 the Energy Ministry confirmed average blending had crossed 18 % nationwide, with some states touching 20 %. A June‑2025 market report even claims the national average briefly hit the full 20 %.

Why biofuels scale quickly

  • Drop‑in fuel: No new engines or pumps required.
  • Rural income: Ethanol plants pay farmers for cane, maize—or better, for crop waste.
  • Lower carbon: Lifecycle emissions fall 40–90 % versus petrol, depending on feedstock.

From 1G to 2G: entering the rice‑straw era– Biofuels & Solar Charging

First‑generation (1G) ethanol still relies mainly on sugarcane. But sugarcane uses a lot of water and competes with food. Second‑generation (2G) plants turn leftover biomass into fuel instead. One leading example is Khaitan Bio Energy, whose patented process converts rice straw into ethanol while recovering valuable silica and using lignin for steam in a zero‑liquid‑discharge set‑up.

Using straw tackles another crisis: open‑field burning. Government studies show India produces roughly 160 million tons of rice straw each year; collecting even one‑quarter could supply 9 billion litres of ethanol—enough for the entire E20 target.

Fresh investment wave

States are wooing capital. At an Excise Investors’ Summit in Lucknow (July 2025) Uttar Pradesh highlighted that it already supplies one‑fifth of India’s ethanol and wants to become an export hub for the fuel. The Union government also allocates surplus Food Corporation rice (still controversial) and offers soft loans for 2G facilities.

Solar‑powered EVs take the fast lane

Rooftop solar makes charging cheap

Electricity is only as clean as its source. India’s answer is to push solar on every roof. Under the PM Surya Ghar – Muft Bijli Yojana PM Surya Ghar – Muft Bijli Yojana launched in 2024, households now get up to 60 % subsidy on small solar systems, with easy online approvals. Delhi’s July‑2025 announcement goes a step further—installers will fit solar arrays for residents with zero upfront cost, paid back from future bill savings.

Result: EV owners can plug in at home and drive on sunshine, cutting running costs to well below ₹1 per km.

Charging hubs tap the sun

Cities are building solar‑roofed public chargers too. In June 2025 Bengaluru opened the country’s first solar‑powered, second‑life‑battery fast‑charging hub, storing daytime solar in reused EV batteries for night use. More projects are planned along highways under the Green NH programme.

Market momentum in 2025

  • Over 50 % of new two‑wheelers sold in Indian metros are electric.
  • Fleet operators switch to battery‑swap models, slashing downtime.
  • FAME‑II and state incentives lower upfront prices each quarter.

EV growth is especially strong in delivery bikes and urban buses—segments that start and end their day at fixed depots ideal for rooftop solar.

Complement, not compete– Biofuels & Solar Charging

Biofuels and solar EVs serve different needs:

Use‑caseBiofuels (E20, B20, 2G)Solar‑charged EVs
Existing cars & farm machinery✔ ready now✖ requires new vehicles
Long rural trips where chargers are scarce✔ fuel stations widespread◆ range depends on infra
Urban delivery, daily commute◆ still cuts CO₂✔ best solution (zero tailpipe)
Cuts stubble burning & supports farmers✔ straw‑to‑fuel✖ no direct link
Powered by Indian sunshine at point of use✖ not directly✔ rooftop or hub‐mounted PV

Both tracks cut oil demand, but they do so in different parts of the fleet. That diversity makes the national target more resilient.

How big could each become?

Using IEA and government roadmaps we can sketch a likely 2030 split of clean transport energy in India:

SolutionShare of clean transport energy by 2030*
Biofuels (ethanol, biodiesel)~40 %
Solar‑powered EVs~35 %
Green hydrogen & fuel cells~15 %
Other tech (CNG, hybrids, etc.)~10 %

*Illustrative blend based on IEA Net‑Zero Scenario and Indian policy targets. 

Conclusion

India’s transport future is not about choosing one path but building a network of solutions. Biofuels like second-generation ethanol made from crop residue offer farmers new income, reduce air pollution from stubble burning, and help decarbonize existing petrol vehicles. At the same time, solar-charged EVs provide zero-emission travel in cities and suburbs, turning rooftops and parking lots into clean energy hubs. To accelerate both, policymakers can extend support for 2G ethanol plants and crop-residue collection, speed up solar and EV infrastructure approvals, set clear recycling and hydrogen standards, and link carbon credits to verified emission cuts. Industry players like Khaitan Bio Energy are expanding clean fuel production, while EV charging networks are working with utilities to send solar power back to the grid—creating a stronger, cleaner transport system for India.

Green Mobility: The Role of Biofuels, EVs, and Hydrogen in 2025

Introduction

As climate concerns become more urgent and fossil fuel supplies increasingly uncertain, 2025 marks a critical turning point for the transportation sector. In this green transition, three sustainable alternatives—biofuels, electric vehicles (EVs), and green hydrogen—are leading the way toward cleaner, more efficient mobility. Together, they promise to reduce carbon emissions, support energy independence, and reshape how people and goods move across cities, countries, and continents.

This blog explores how these three technologies are shaping India’s and the world’s mobility landscape in 2025, the challenges they face, and the crucial role of policy, innovation, and industry players like Khaitan Bio Energy in driving change.

Why Green Mobility Matters Now More Than Ever

Transportation accounts for nearly 25% of global CO₂ emissions, with road transport being the biggest contributor. In India, the sector is not just a source of pollution but also a major drain on imported fossil fuels. As cities choke on smog and fuel prices fluctuate, governments, businesses, and citizens are realizing the need to transition to greener options.

Key Goals of Green Mobility:

  • Reduce dependence on imported oil
  • Cut greenhouse gas and particulate emissions
  • Improve urban air quality
  • Create local jobs in clean tech sectors
  • Align with international climate targets (like Net Zero by 2070 for India)

Green Mobility – A Bridge Toward Cleaner Transport

Biofuels, particularly ethanol and biodiesel, are renewable fuels made from organic materials like sugarcane, maize, used cooking oil, and agricultural waste. In India, the Ethanol Blending Programme (EBP) aims to blend 20% ethanol into petrol by 2025–26.

Benefits of Biofuels:

  • Can be used in existing internal combustion engine vehicles (ICEVs)
  • Lower lifecycle emissions compared to petrol and diesel
  • Stimulate rural economy by utilizing agricultural waste
  • Reduce stubble burning by using crop residues like rice straw

Types of Biofuels:

TypeSourceUse Case
1G EthanolSugarcane, cornPetrol blending
2G EthanolRice straw, agri wasteCleaner, non-food-based fuel
BiodieselUsed cooking oil, animal fatsDiesel vehicle alternative
Bio-CNGOrganic municipal/agri wastePublic transport, logistics

Real-world Impact:

By February 2025, India has reached nearly 17.98% ethanol blending, and new 2G ethanol plants are being commissioned across the country.

Khaitan Bio Energy

Khaitan Bio Energy is among the pioneers producing 2G ethanol from rice straw, using zero-liquid discharge (ZLD) technology and valorizing byproducts like silica and lignin. Their work directly contributes to reducing stubble burning and achieving India’s blending goals—while empowering farmers with new income streams.

Electric Vehicles (EVs) – Quiet, Efficient, and Rapidly Scaling

EVs have gained tremendous momentum globally and in India. With government subsidies, improved infrastructure, and rising consumer interest, EVs are transitioning from niche to mainstream.

Advantages of EVs:

  • Zero tailpipe emissions
  • Lower maintenance and running costs
  • Growing charging infrastructure
  • Quiet and smooth driving experience

Challenges:

  • High upfront cost (though decreasing)
  • Battery range anxiety
  • Charging station availability in rural areas
  • Recycling and sourcing of rare earth minerals

Government Support in 2025:

  • FAME II Scheme continues to offer incentives for two-, three-, and four-wheelers.
  • State governments offer tax exemptions, registration fee waivers, and subsidies.
  • Many cities are shifting public buses and taxis to electric fleets.
  • Electric two-wheelers and rickshaws dominate the urban mobility space.
  • Battery-as-a-service and swapping models are expanding in metro areas.
  • Companies like Tata Motors, Ola Electric, Ather, and MG have launched newer, more affordable EV models.

Hydrogen – The Future Fuel?

Hydrogen, especially green hydrogen produced using renewable electricity, is gaining interest for hard-to-decarbonize sectors like heavy-duty transport, shipping, and aviation.

Why Hydrogen?

  • High energy density and long driving range
  • Can fuel large vehicles like buses, trucks, and trains
  • Emission-free when used in fuel cells (only water as a byproduct)

India’s Hydrogen Push:

In 2023, the government launched the National Green Hydrogen Mission, aiming to make India a global hub for hydrogen production and exports. By 2025:

  • Pilot projects are running hydrogen buses in cities like Delhi and Pune.
  • Green hydrogen is being used in some industrial and rail transport applications.
  • Investments are flowing into electrolyzer manufacturing and hydrogen infrastructure.

Challenges Ahead:

  • High production and storage cost
  • Lack of fueling infrastructure
  • Competition with other clean energy sources

The Role of Policy and Innovation

The future of green mobility doesn’t rely on a single solution. A multi-tech approach is key—using the best fuel or vehicle type for the right application.

Governments must continue to:

  • Provide incentives for clean vehicle adoption
  • Invest in renewable energy and infrastructure
  • Encourage R&D in storage, fuel cells, and recycling
  • Support startups and biofuel plants like Khaitan Bio Energy

Private sector innovation, from battery management to biomass processing, is also essential. Collaboration between EV makers, fuel producers, and smart grid developers can accelerate the transition.

What Can Individuals and Businesses Do?

For Individuals:

  • Choose an EV or FFV (flex-fuel vehicle) for your next purchase.
  • Support brands that prioritize sustainability.
  • Spread awareness and demand clean transport options.

For Businesses:

  • Electrify your vehicle fleet where feasible.
  • Partner with 2G biofuel producers for low-emission logistics.
  • Use renewable energy in warehousing and transport hubs.

Conclusion: A United Path Toward Cleaner Roads

The transportation sector is undergoing a massive transformation in 2025. While electric vehicles are capturing urban markets and green hydrogen is shaping up for the long haul, biofuels like those produced by Khaitan Bio Energy are proving essential for bridging the gap—especially in agriculture and rural India.

Each solution has a unique role to play. Together, they form the foundation of green mobility—a path that ensures cleaner air, economic growth, and energy security for the generations to come.

India’s green future is not a dream—it’s in motion. The road ahead is electric, bio-powered, and hydrogen-fueled.

Net Zero Goals 2050: Will Biofuels Bridge the Energy Gap?

Net Zero by 2050: Ambition or Achievable?

The world is racing to meet its Net Zero Goals by 2050. That means cutting greenhouse gas emissions to nearly zero and offsetting any remaining emissions through carbon capture or nature-based solutions. The goal is urgent, and the stakes are enormous: prevent global temperatures from rising more than 1.5°C and avoid irreversible damage to ecosystems, agriculture, and human health.

Global leaders are betting on solar, wind, electric vehicles, green hydrogen, and carbon capture. But one key player is often underestimated—biofuels. As the world’s energy demand keeps rising, and not all sectors can shift to electricity immediately, could biofuels be the missing piece?

What Are Biofuels and Why Are They Important?

Biofuels are renewable fuels made from organic materials such as crops, agricultural waste, or used cooking oil. Ethanol and biodiesel are the most common types. They can be blended with conventional fuels and used in existing engines with little to no modification.

Their significance lies in their ability to replace fossil fuels, especially in sectors where clean electricity isn’t yet viable—like aviation, maritime, and heavy-duty transportation. Unlike fossil fuels, biofuels emit significantly lower carbon dioxide over their lifecycle, particularly when produced from waste materials or residues.

India’s Biofuel Push: Progress on the Ground

India has emerged as a biofuel leader among developing nations. The Ethanol Blended Petrol (EBP) Programme, launched in 2003, has recently gained momentum. From a mere 1.5% ethanol blend in 2014, India touched nearly 12% in 2023, and aims to reach 20% blending by 2025.

This rapid transition serves multiple purposes: reducing crude oil imports, supporting farmers, curbing air pollution, and lowering CO₂ emissions. The government has allowed ethanol production from damaged food grains, maize, and surplus rice stock, while encouraging use of newer feedstocks like crop residues for 2G (second-generation) ethanol.

This is especially relevant in northern India, where stubble burning remains a major source of winter air pollution. Transforming that waste into biofuel could reduce both emissions and smoke-induced health problems.

What Makes Biofuels “Green”?

Biofuels are considered carbon-neutral because the CO₂ released during combustion is largely offset by the CO₂ absorbed by plants during growth. But that’s only true for advanced biofuels like 2G ethanol, produced from non-edible biomass—crop stubble, wood chips, and even algae.

First-generation (1G) biofuels, on the other hand, are made from sugarcane, corn, or palm oil. These can compete with food crops and sometimes lead to deforestation or excessive water use. That’s why global efforts now focus on scaling sustainable biofuels, using waste and low-input crops.

Where Does the World Stand?

Globally, biofuel production must triple by 2030 to stay on track with net-zero goals, according to the International Energy Agency (IEA). The world is not yet on that path. Although renewable electricity has seen explosive growth, sectors like aviation, shipping, and long-haul transport remain stubbornly dependent on fossil fuels.

In aviation, for example, Sustainable Aviation Fuel (SAF) accounts for less than 1% of total jet fuel usage. A recent report by the International Air Transport Association (IATA) indicated that even optimistic projections show SAF making up just 5% of fuel by 2030 unless major investments flow into production.

One reason: biofuel production remains capital-intensive, especially for second-gen fuels. Feedstock availability, refining technology, and transportation logistics all require coordinated planning and investment.


In 2024, India announced an aggressive expansion of biofuel infrastructure. The Centre for High Technology (CHT) identified over 60 biodiesel plants for blending diesel with up to 5% biodiesel starting April 2024.

India’s Global Biofuels Alliance (GBA)—launched at the G20 summit—seeks to pool resources across countries to build robust supply chains and exchange technology. This move positions India as a global leader in sustainable fuel diplomacy.

Meanwhile, climate reports globally are sounding alarms. The Lancet Countdown 2024 emphasized that health risks from climate change are rising sharply, urging countries to speed up low-carbon transitions. Biofuels, being locally sourced and rural-friendly, also contribute to economic resilience.

Can Biofuels Bridge the Gap Alone?

Not entirely. While biofuels are essential, especially for decarbonizing transport, they cannot replace fossil fuels at full scale without significant breakthroughs.

Challenges include:

  • Feedstock constraints: Competing land use for food vs. fuel is a key issue with 1G biofuels.
  • Technology barriers: 2G and 3G (algae-based) fuels are promising but not yet scalable at low cost.
  • Infrastructure needs: Collection of biomass, storage, and transport all need upgrades.
  • Policy and investment gaps: Long-term financing and consistent policy frameworks are still developing.

Still, when used smartly—especially for hard-to-electrify sectors—biofuels can reduce dependence on fossil fuels and complement electric mobility and hydrogen.

Role Of Khaitan Bio Energy

One of the promising players in this field is Khaitan Bio Energy (KBIO), a company actively building scalable solutions in 2G ethanol production. Their technology turns agricultural residues—like rice straw—into high-quality ethanol, without competing for food crops or clean water.

What makes KBIO’s work significant is their zero-liquid-discharge model, which minimizes environmental impact. Their facility integrates bioenergy with carbon savings, and their collaborations with rural stakeholders create both jobs and cleaner air.

By focusing on crop waste that would otherwise be burned in open fields, KBIO offers a dual solution—lowering CO₂ and tackling air pollution. Their model shows how innovation in India can contribute globally to climate action.

The Global Math: Investments and Land Use

To meet its net-zero goals, India will need nearly $12.7 trillion in energy investments by 2050, according to a 2021 BloombergNEF study. Biofuels will be a part of this, along with solar, hydrogen, EVs, and grid upgrades.

But it’s not just about money. Land use is another dimension. Solar and wind will require over 65,000 sq km of land—about twice the size of Kerala. Biofuel crops and feedstock will add pressure, unless waste biomass is prioritized.

That’s where 2G and decentralized production models—like KBIO’s—are critical. They reduce land demand, minimize transport emissions, and create circular rural economies.

Policies Driving Biofuel Progress

India’s National Bioenergy Programme, restructured in 2022, now supports multiple technologies: compressed biogas, biomass pellets, and bioethanol. The focus is shifting from sugarcane and molasses to maize, surplus grains, and residues.

At the global level, the UN and IEA call for stronger biofuel mandates and better pricing mechanisms. Countries like Brazil, the U.S., and Sweden already have mature ethanol blending systems, often supported by carbon credit schemes.

India, too, must build carbon markets and reward low-carbon fuels. More R&D funding, decentralized refinery models, and public-private partnerships will drive future momentum.

Final Thoughts: A Fuel That Matters

Biofuels are not a silver bullet. But they are a necessary, flexible, and scalable solution—especially in regions where electrification will take longer.

When sourced responsibly and made from waste, they offer a low-carbon bridge to the future. They support farmers, reduce pollution, and complement larger renewable transitions. With the right incentives, investment, and technology, biofuels can be a major pillar of Net Zero Goals by 2050 .

As India prepares for E20, and countries assess sustainable aviation and shipping fuels, bioenergy deserves its place at the table. Not just as a cleaner fuel—but as a smart, inclusive tool for climate justice.

Empowering India’s Green Future: Innovative Biofuel Solutions

India’s drive to blend 20 percent ethanol into petrol by 2025–26 and thereby achieving green future represents a critical step toward reducing oil imports, cutting greenhouse gas emissions, and supporting rural incomes. Initially, sugarcane and surplus rice were the primary feedstocks for ethanol production—so-called first-generation (1G) biofuels. However, mounting evidence shows that reliance on these food crops is neither sustainable nor scalable. From falling sugarcane yields and water scarcity to concerns over diverting staple grains, it’s clear that India must look beyond sugar and rice. Second-generation (2G) ethanol—made from agricultural residues like rice straw—offers a far more sustainable path. Companies such as Khaitan Bio Energy are leading this transition, demonstrating how innovative technologies can convert farm waste into clean fuel while protecting food security and the environment.

Why Sugar-Based Ethanol Is Losing Steam

For over a decade, India’s ethanol blending program for green future depended heavily on sugarcane, using both molasses and cane juice. Yet recent trends have exposed serious constraints:

  • Declining Yields: Poor monsoon rains, disease outbreaks (e.g., red rot), and soil exhaustion have cut sugarcane output from 315.4 lakh tonnes in 2023–24 to 257.4 lakh tonnes in 2024–25.
  • Water Intensity: Producing one litre of sugarcane ethanol can require up to 2,860 litres of water—unsustainable in water-stressed regions like Maharashtra and Uttar Pradesh.
  • Price Sensitivity: Global sugar price fluctuations directly affect ethanol economics. When sugar prices rise, mills divert less cane to ethanol, threatening blending targets.
  • Geographical Limits: Sugarcane cultivation and associated distilleries are concentrated in a few states, creating transport bottlenecks and uneven blending infrastructure across India.

Together, these factors mean sugar-based ethanol alone cannot meet India’s growing fuel-blending targets without jeopardizing water resources, crop incomes, and the reliability of ethanol supply.

The Rice Diversion Dilemma

To diversify, the government approved the use of Food Corporation of India (FCI) rice for ethanol. In May 2025, an additional 2.8 million tonnes of FCI rice were sanctioned—bringing total rice allocation to 5.2 million tonnes for the 2024–25 ethanol supply year Down To Earth. While this move helped boost ethanol output—enough to produce roughly 2.45 billion litres—diverting rice poses serious risks:

Food Security

Rice is a staple food for a large part of India’s population. Diverting millions of tonnes of it toward ethanol production could threaten food availability, especially in years when harvests are lower than usual. This diversion could lead to price hikes, making rice less affordable for many, and increasing the risk of food insecurity in vulnerable communities.

Supply Chain Strain

Increased demand for rice to produce ethanol puts pressure on India’s well-established food procurement and distribution systems. These systems are vital for delivering subsidized food to millions of people. Using large quantities of rice for fuel could disrupt these networks, causing logistical bottlenecks and reducing the efficiency of food delivery mechanisms.

Policy Backlash

The use of food grains like rice for fuel has triggered concern among both the public and policymakers. It raises ethical and strategic questions about prioritizing fuel over food. This ongoing debate highlights the urgent need for more sustainable and non-food-based alternatives, such as second-generation ethanol from agricultural waste like rice straw for a green future.

The rice-for-fuel strategy is a stopgap at best. Long-term energy security demands feedstocks that spare the country’s precious food reserves.

Why 2G Ethanol from Rice Straw Makes Sense

Second-generation (2G) biofuels use non-food biomass—lignocellulosic residues such as rice straw, wheat straw, corn stover, and forestry waste. Rice straw stands out for several reasons:

  • Abundant Raw Material: India generates an estimated 168 million tonnes of rice straw annually, with 39–47 million tonnes available as surplus Down To Earth.
  • Stubble Burning Mitigation: Farmers routinely burn rice straw to clear fields, causing severe air pollution. Converting straw to ethanol reduces this practice and its health hazards.
  • No Food Competition: Rice straw is a waste product, so its use for fuel does not compromise food availability.
  • Rural Livelihoods: Purchasing straw for ethanol gives paddy farmers an extra income stream, boosting rural economies.

By tapping into rice straw, India can scale ethanol production without the drawbacks of sugarcane or rice grain feedstocks.

 Comparing Ethanol Feedstocks

Benefits and Challenges of 2G Ethanol

Benefits:

  • Sustainability: Utilizes waste; avoids food-fuel conflicts.
  • Emission Reductions: Cuts open-field burning and greenhouse gases.
  • Economic Uplift: Creates new markets for farm residues; spurs bio-refinery jobs.

Challenges:

  • Technology Complexity: Lignocellulosic biomass requires advanced pre-treatment and enzymes to release fermentable sugars.
  • Higher Capital Costs: 2G bio-refineries need greater upfront investment than 1G plants.
  • Logistics: Collecting, transporting, and storing bulky straw feedstocks demands robust supply chains.

The chart shows a balanced view of key advantages like environmental benefits, rural income support, and emissions reduction, along with notable challenges such as high setup cost, technological complexity, and supply chain issues.

Overcoming these issues requires targeted policy support, technology partnerships, and financing models that de-risk investment in 2G infrastructure.

 Khaitan Bio Energy’s Game-Changing Role

Khaitan Bio Energy has emerged as a pioneer in India’s 2G biofuel landscape focussing green future. It has patented technology to produce 2G Ethanol using biomass with zero discharge from the  biorefinery. The main features of the technology are:

  • Integrated, Zero-Liquid-Discharge (ZLD) Design: Efficient water recycling and minimal effluent generation.
  • Advanced Pretreatment: Energy-efficient reactors and enzymatic hydrolysis processes maximize sugar yield from tough rice straw fibers.
  • Byproduct Valorization: Extracted silica and lignin are used for steam generation, enhancing plant economics and sustainability.
  • Local Farmer Engagement: Contracts with paddy growers ensure a reliable straw supply, boosting rural incomes and reducing stubble burning.

By combining cutting-edge technology with circular-economy principles, Khaitan Bio Energy demonstrates how 2G ethanol can be both environmentally and commercially viable.

Policy and Investment Imperatives

To scale 2G ethanol from rice straw nationally, coordinated action is needed:

  • Incentives for Feedstock Supply: Minimum purchase prices for straw and grants for collection infrastructure.
  • Capital Subsidies: Loan guarantees and viability gap funding for 2G plant developers.
  • Research & Development Support: Grants for process optimization and enzyme cost reduction.
  • Blending Mandate Flexibility: Progressive blending targets that recognize the longer ramp-up for 2G capacity.

Such measures will encourage more private and public players to enter the 2G ethanol space, accelerating India’s green-fuel transition.

The Road Ahead

India’s ethanol blending journey must evolve from its 1G origins to embrace multi-feedstock strategies centered on sustainability. Rice straw–based 2G ethanol addresses the twin challenges of energy security and agricultural pollution.

Rethinking Ethanol: Moving Beyond Sugar and Rice to a Sustainable Future with Rice Straw

Introduction

India has set an ambitious goal: blending 20% ethanol into petrol by 2025–26. This move aims to reduce the country’s dependence on imported oil and lower greenhouse gas emissions. However, the path to achieve Moving Beyond Sugar and Rice by Rethinking Ethanol target is fraught with challenges, especially concerning the sources of ethanol production. Traditionally, ethanol in India has been produced from sugarcane and surplus food grains like rice. While these sources have served well initially, they are now presenting significant constraints, prompting a shift towards more sustainable alternatives like second-generation (2G) ethanol derived from rice straw.

The Limitations of Sugar-Based Ethanol: Why India Needs to Look Beyond Sugar

India is aiming to blend 20% ethanol into petrol by 2025–26 to reduce oil imports and fight pollution. For the past few years, most of India’s ethanol has come from sugarcane, especially molasses and sugarcane juice. While this helped launch India’s ethanol program, it’s now clear that sugar alone can’t take us all the way. There are serious problems with relying too much on sugarcane to make ethanol.

Let’s take a closer look at the limitations—and why it’s time to explore better, cleaner alternatives.

1. Sugarcane Production Is Falling

Sugarcane farming depends a lot on water, healthy soil, and good weather. Recently, sugar output has been falling because of:

  • A disease called red rot damages crops.
  • Less rainfall and dry weather in key sugarcane regions.
  • Lower sugar recovery rates, meaning less sugar is extracted from the same crop.

In the 2024–25 season, India’s sugar production dropped from 315.4 to 257.4 lakh metric tons. This directly affects ethanol production, as less sugar means less ethanol.

2. Too Much Water Is Needed

Sugarcane needs a lot of water. Producing just one litre of ethanol from sugarcane can take nearly 2,860 litres of water. In areas where water is already scarce, this puts a big strain on farmers and the environment.

If we continue to use sugarcane for ethanol, it may worsen water shortages, especially in places like Maharashtra and Uttar Pradesh.

3. Using Sugar for Fuel Affects Food Prices

Sugar is not just for making ethanol—it’s a food product. If more sugarcane is used to make fuel, there’s less sugar available for people to eat. This can cause sugar prices to rise.

Also, if ethanol prices go up or sugar production falls, the fuel supply is affected. This creates a risky situation where food and fuel are competing for the same crop.

4. Limited to Few States

Sugarcane is grown mostly in certain states. Ethanol plants are usually located near these sugarcane farms. This means:

  • Ethanol has to be transported long distances, which costs more.
  • Some states don’t have the right infrastructure to blend ethanol into petrol.

So, relying only on sugar-based ethanol doesn’t support nationwide fuel blending equally.

5. Climate Risks

Sugarcane farming is vulnerable to climate change. Unpredictable rains, extreme heat, and crop diseases make it hard to grow sugarcane consistently. This means ethanol supply from sugar is unstable and risky for the future.

The Risks of Diverting Rice for Ethanol

In an attempt to diversify ethanol sources, the government approved the use of surplus rice from the Food Corporation of India (FCI) for ethanol production. While this move aims to utilize excess stock, it raises several concerns:

  • Food Security Threats: Diverting rice, a staple food for a significant portion of the population, towards ethanol production can lead to food shortages and increased prices, especially during years of poor harvests.
  • Environmental Concerns: Rice cultivation is water-intensive. Increasing its production for ethanol purposes can strain water resources, exacerbating environmental issues.
  • Policy Implications: The decision to use food grains for fuel has sparked debates about the balance between energy needs and food security, emphasizing the need for alternative solutions.

Embracing 2G Ethanol from Rice Straw: A Sustainable Alternative

Given the challenges associated with sugarcane and rice, attention is turning towards second-generation (2G) ethanol produced from agricultural residues like rice straw. This approach offers multiple benefits:

  • Abundant Raw Material: India produces approximately 168 million tons of rice straw annually, with about 39 to 47 million tons available as surplus. Utilizing this waste not only provides a sustainable feedstock for ethanol but also addresses the issue of stubble burning, which contributes to air pollution.
  • Environmental Benefits: Converting rice straw into ethanol reduces greenhouse gas emissions and mitigates the environmental hazards associated with stubble burning.
  • Economic Opportunities: This approach can provide farmers with an additional source of income by selling their agricultural waste, promoting rural development.

Khaitan Bio Energy: Leading the 2G Ethanol Revolution

Khaitan Bio Energy is at the forefront of this sustainable shift. The company has patented technology to produce 2G ethanol using rice straw, demonstrating high efficiency and lower costs due to production of additional products namely, Silica and Gypsum. Their pilot plant has already showcased an end-to-end process with zero liquid discharge, utilizing advanced technologies for sugar treatment, dewatering, and recycling. Prioritising a sustainable and green future is the need of the hour and Khaitan Bio Energy is committed to achieving that goal through its innovations.

Conclusion: Charting a Sustainable Path Forward

India’s ethanol blending targets are commendable, aiming to enhance energy security and reduce environmental impact. However, the current reliance on sugarcane and rice poses significant challenges, including food security risks and environmental concerns. Embracing 2G ethanol production from rice straw offers a viable and sustainable alternative, addressing these issues while promoting rural development and environmental conservation.

Driving Change: Why Green Fuels Are No Longer Optional

Introduction: The World is at a Crossroads

The energy choices we make today will define the world we live in tomorrow. As climate change accelerates, energy prices rise, and pollution worsens, one thing is clear—fossil fuels are no longer sustainable. We’ve reached a point where switching to green fuels is not just an environmental decision, but a critical necessity for economic, social, and public health survival.

Across the globe, from India to the EU, governments, businesses, and innovators are investing in alternative fuels to reduce emissions, secure energy independence, and create sustainable growth. Among these alternatives, green fuels stand out as one of the most promising solutions.

What Are Green Fuels?

Green fuels, also called biofuels or renewable fuels, are derived from organic and renewable sources such as plant biomass, algae, or agricultural and municipal waste. Unlike fossil fuels, they release significantly lower levels of greenhouse gases when burned and don’t rely on finite natural resources.

The most common types of green fuels include:

  • Ethanol: typically made from sugarcane, corn, or agricultural waste
  • Biodiesel: produced from vegetable oils or animal fats
  • Biogas: created from organic waste through anaerobic digestion
  • Green hydrogen: generated from water using renewable electricity
  • Green methanol and synthetic fuels: used in industries like shipping and aviation

Why Green Fuels Are No Longer Optional

1. Climate Change Is an Immediate Threat

The last two years have seen some of the most extreme weather events in human history—record-breaking heat in Europe, catastrophic floods in Pakistan and India, and wildfires across Canada, Greece, and the U.S. These events are closely tied to greenhouse gas emissions from fossil fuels.

The Intergovernmental Panel on Climate Change (IPCC) warned in its 2023 report that without urgent action, the planet will exceed 1.5°C of warming within the next decade. Green fuels offer a practical way to decarbonize sectors like transport, aviation, and heavy industry—areas where electric alternatives are limited or still under development.

2. Fossil Fuel Volatility Undermines Energy Security

The Russia-Ukraine war exposed how vulnerable the global economy is to fossil fuel dependence. Oil and gas prices soared, supply chains were disrupted, and nations scrambled to secure energy. In contrast, green fuels—especially those produced domestically—offer a stable, local, and renewable energy source.

Countries like India, Brazil, and even oil-rich Gulf nations like the UAE are now focusing on building large-scale green fuel capacities to protect themselves from such geopolitical shocks.

3. Pollution Is a Public Health Crisis

According to the World Health Organization (WHO), air pollution causes over 7 million deaths annually. A major source of this pollution is vehicle exhaust from petrol and diesel. Switching to bioethanol or biodiesel blends drastically reduces emissions of particulate matter, carbon monoxide, and sulfur oxides, improving urban air quality.

In India, using 20% ethanol-blended petrol can reduce harmful emissions by up to 30%, while also improving fuel efficiency. It’s a cleaner, healthier alternative that benefits everyone—especially those living in densely populated cities.
