India crossed a historic milestone in 2023 by achieving 10% ethanol blending (E10) in petrol ahead of schedule, followed by the ambitious rollout of E20 – a 20% ethanol-petrol blend. This transition marked a significant step toward energy independence and environmental sustainability. But as E20 becomes the new normal, a pressing question emerges: what’s next for India’s biofuel ambitions? The answer lies in E30, advanced biofuels, and a comprehensive renewable energy roadmap that could reshape the nation’s fuel landscape by 2026 and beyond.
India's E20 Milestone: Setting the Stage
The journey from E10 to E20 wasn’t just about increasing ethanol percentages – it represented a fundamental shift in India’s energy strategy. By blending 20% ethanol with petrol, India reduced its dependence on crude oil imports, saving billions of dollars annually while cutting carbon emissions significantly. The initiative also provided a major boost to sugarcane farmers and distilleries, creating a robust domestic supply chain.
However, E20 is not the final destination. With the Ministry of Petroleum & Natural Gas eyeing more ambitious targets, India is preparing for the next phase of its biofuel revolution. The roadmap includes E30 blending, second-generation ethanol production, and diversification into biodiesel and sustainable aviation fuel.
The Road to E30: India's Next Biofuel Frontier
Official Timeline and Government Vision
India’s E30 target – 30% ethanol blending in petrol – is expected to roll out between 2028 and 2030, depending on infrastructure readiness and feedstock availability. The government has already initiated discussions with automobile manufacturers to ensure vehicle compatibility, while oil marketing companies are upgrading their blending infrastructure. States like Uttar Pradesh, Maharashtra, and Karnataka, which lead in ethanol production, will likely pioneer the E30 transition.Why E30 Matters for India’s Future
The shift to E30 carries transformative potential across multiple dimensions. Economically, it could reduce India’s crude oil import bill by an additional $4-5 billion annually, strengthening energy security. Environmentally, E30 promises deeper carbon emission cuts, aligning with India’s commitment to net-zero by 2070. Socially, higher ethanol demand will create more opportunities for rural economies, particularly for farmers growing sugarcane and emerging energy crops.Infrastructure and Vehicle Readiness
The technical groundwork for E30 is already underway. Modern BS-VI compliant vehicles can handle higher ethanol blends with minimal modifications. The government is also promoting flex-fuel vehicles (FFVs) that can run on any ethanol-petrol combination from E20 to E100. Major automakers including Maruti Suzuki, Toyota, and Bajaj Auto have announced plans to introduce FFV models, making the transition smoother for consumers.Beyond Ethanol: Diversifying India's Biofuel Portfolio
Second-Generation Ethanol: The Game Changer
While conventional ethanol comes from food crops like sugarcane and corn, second-generation (2G) ethanol is produced from agricultural waste, rice straw, wheat stubble, and biomass. This technology addresses two critical challenges simultaneously – managing agricultural waste and producing sustainable fuel without competing with food security. Indian Oil Corporation has already commissioned India’s first 2G ethanol plant in Panipat, with a capacity of 100 kiloliters per day. The government’s Production Linked Incentive (PLI) scheme offers substantial financial support to companies investing in 2G ethanol technology, signaling a strong policy push toward advanced biofuels.Biodiesel and the B20 Target
Parallel to ethanol blending, India is pursuing biodiesel targets with equal vigor. The B20 program aims for 20% biodiesel blending in diesel by 2025-2026. Unlike ethanol, biodiesel is derived from non-edible oils such as Jatropha, Karanja, and used cooking oil (UCO). The government’s UCO collection mechanism has gained momentum, with partnerships between oil companies and restaurants, hotels, and food processing units creating a circular economy model. The Sustainable Alternative Towards Affordable Transportation (SATAT) initiative further expands this vision by promoting compressed biogas (CBG) from organic waste. With a target of 5,000 CBG plants, SATAT could revolutionize India’s commercial transport sector while addressing urban waste management challenges.Sustainable Aviation Fuel: The Next Frontier
As global aviation commits to carbon neutrality, India is developing its own sustainable aviation fuel (SAF) roadmap. Early-stage pilot projects are exploring SAF production from used cooking oil and agricultural residues. While still nascent, India’s SAF ambitions could position the country as a key player in the global green aviation market by 2030.Challenges on the Path Forward
Despite the promising roadmap, several challenges must be addressed for successful implementation. Feedstock availability remains a primary concern – scaling up to E30 and beyond requires massive increases in ethanol production without compromising food security or diverting agricultural land. The solution lies in accelerating 2G ethanol capacity and diversifying feedstock sources.
Infrastructure upgrades across refineries, blending facilities, and distribution networks demand significant capital investment. Price volatility in ethanol and biodiesel markets also poses risks, requiring stable pricing mechanisms and long-term contracts between producers and oil companies.
Consumer awareness remains another critical factor. Many vehicle owners are still unfamiliar with higher ethanol blends and their benefits. A comprehensive public awareness campaign highlighting cost savings, environmental benefits, and vehicle compatibility is essential for widespread adoption.
India's Competitive Advantage in the Global Context
The Path Ahead: 2026 and Beyond
Conclusion
India’s biofuel journey doesn’t end with E20 – it’s just beginning. The roadmap to E30, coupled with advances in 2G ethanol, biodiesel blending, and sustainable aviation fuel, demonstrates India’s commitment to a cleaner, more self-reliant energy future. While challenges exist, the combination of supportive policies, technological innovation, and growing infrastructure readiness suggests that India’s post-E20 ambitions are not just achievable but inevitable.
As we move toward 2026 and beyond, stakeholders across the energy ecosystem must collaborate to realize this vision. The transition to higher biofuel blending isn’t merely a policy goal – it’s a national imperative that will define India’s energy security and environmental legacy for generations to come.
