The report presents a comprehensive perspective on the evolution of India’s ethanol blending programme and its transition into a large-scale, integrated transport fuel ecosystem. Over the past decade, the Ethanol Blended Petrol (EBP) programme has scaled significantly, with blending levels rising from ~1.5 per cent in 2013–14 to achieving E20 much ahead of schedule in 2025–26. This progress reflects strong policy support and coordinated execution across agriculture, distillation, Oil Marketing Companies (OMCs), logistics, and retail fuel distribution. As a result, ethanol has become an integral component of India’s transport fuel system, delivering measurable benefits such as reduced crude oil imports, foreign exchange savings, lower carbon emissions, and enhanced rural income generation through agricultural linkages.
While this achievement marks a significant milestone, the report emphasises that E20 is not the endpoint of India’s ethanol journey but rather a strategic inflection point. It highlights the need to reposition ethanol from a fixed blending component to a more central role within the transport fuel system. In this context, ethanol is framed as a potential “transport energy backbone,” capable of strengthening energy security and reducing India’s exposure to global crude oil price volatility. Given that India’s fuel economy remains highly sensitive to fluctuations in global oil markets, the ability to leverage a domestically produced fuel such as ethanol offers a pathway to improve resilience, moderate inflationary pressures, and enhance overall fuel system stability.
A key focus of the report is the transition from a single-blend system to a more flexible and diversified ethanol-driven fuel architecture. This includes the gradual introduction of higher ethanol blends such as E22–E30 and the development of flex-fuel pathways such as E85 and E100. Initial developments, including the rollout of flex-fuel vehicles and early-stage infrastructure for higher blends, indicate that the transition has already begun. However, the report identifies several structural challenges that need to be addressed to enable large-scale adoption beyond E20. These include limitations of first-generation (1G) feedstocks such as sugarcane and grains, which raise concerns around scalability and resource intensity; a demand ceiling under fixed blending mandates; pricing rigidity within the current cost-based procurement framework; infrastructure constraints in delivering multiple fuel grades; and limited penetration of flex-fuel vehicles (FFVs).
To address these challenges, the report outlines a system-level transformation anchored in five key pillars: feedstock diversification, demand expansion beyond the E20 ceiling, pricing evolution toward market responsiveness, infrastructure upgrades to support multi-grade fuel systems, and the development of a compatible vehicle ecosystem. In particular, it underscores the importance of advancing second-generation (2G) ethanol derived from agricultural residues, municipal solid waste, and other non-food feedstocks to enable sustainable long-term scaling without creating pressure on food systems or natural resources.
A notable concept introduced in the report is the role of ethanol as a “crude shock buffer.” Unlike static blending mandates, a flexible ethanol utilisation framework can allow ethanol consumption to adjust dynamically based on global fuel market conditions. During periods of high crude prices or supply disruptions, ethanol utilisation can expand to partially substitute petrol and reduce import dependence. Conversely, during periods of low crude prices, ethanol utilisation can stabilise at baseline levels or be redirected toward alternative pathways such as sustainable aviation fuel (SAF). This dynamic mechanism positions ethanol as a stabilising lever within the transport fuel system, capable of moderating external shocks and enhancing overall energy resilience.
