India's ethanol blending beyond E20: feedstock, flex-fuel and policy gaps
Synopsis
Key Takeaways
India's ethanol blending programme has crossed a landmark threshold, with E20 — a 20 per cent ethanol blend in petrol — operationalised nationwide ahead of schedule, according to a report released on Saturday, 13 June by KPMG in India. The report examines what comes next as the biofuel sector moves beyond this milestone and into a structurally more complex phase of growth.
From Scale to System Intelligence
The central argument of the KPMG report is that India's ethanol journey has outgrown its original mandate. Achieving E20 was a supply-side victory; sustaining momentum now demands a qualitative shift. Anish De, Global Head of Energy, Natural Resources and Chemicals at KPMG International, put it directly: 'Having achieved the E20 milestone ahead of schedule, the imperative now is to move from scale creation to system intelligence — where ethanol transitions from a blending mandate to a foundational pillar of a resilient, flexible and future-ready transport fuel ecosystem.'
This framing marks a significant evolution in how policymakers and industry are expected to approach the programme going forward.
Feedstock Diversification: The Critical Gap
The report identifies feedstock availability as one of the most pressing structural challenges. India's ethanol supply has historically leaned heavily on sugarcane and its derivatives — a first-generation pathway that carries inherent food-fuel competition risks. The KPMG findings call for expanded adoption of alternative feedstocks, including maize and agricultural residues, alongside a meaningful scale-up of second-generation (2G) ethanol production.
2G ethanol, derived from non-food biomass such as crop stubble and wood waste, is seen as the most viable route to incremental supply without straining food security. However, production efficiency improvements and technology investments remain prerequisites before 2G can contribute at scale.
Infrastructure and Supply Chain Readiness
Beyond feedstock, the report highlights significant gaps in blending and distribution infrastructure. Moving to higher blends — beyond E20 toward E25 or E30 — will require storage, transportation and distribution systems capable of handling multi-grade fuel simultaneously. Current infrastructure, largely designed around single-grade supply chains, is not yet equipped for that complexity.
Improved coordination, transparency and system-level visibility across the ethanol value chain are identified as critical enablers. Without these, operational inefficiencies and supply disruptions could undermine the reliability of higher-blend rollouts.
Demand-Side Flexibility and Flex-Fuel Vehicles
Vivek Rahi, Partner and National Head, Oil and Gas at KPMG in India, stressed that demand-side flexibility is equally important: 'India's ethanol journey has evolved from a targeted blending directive to a structurally significant component of the nation's transport energy architecture. As the sector advances beyond E20, the strategic priority must shift toward feedstock diversification, demand-side flexibility and infrastructure alignment at scale.'
A key lever on the demand side is the scaling of flex-fuel vehicle (FFV) adoption. Flex-fuel vehicles can run on any blend of petrol and ethanol, giving consumers and distributors greater flexibility as blend ratios evolve. Broader FFV penetration would also reduce the risk of consumer-side resistance to higher blends.
Policy Alignment and Pricing Mechanisms
The report underscores that policy coherence — across ministries handling agriculture, petroleum, and transport — will be decisive. Pricing mechanisms for ethanol procurement need to be stable and predictable enough to incentivise investment in 2G capacity and alternative feedstocks without creating market distortions. Addressing the food-fuel balance in a country where agricultural policy is deeply politically sensitive adds another layer of complexity that technical solutions alone cannot resolve.
As India charts its post-E20 trajectory, the KPMG findings suggest the next phase will be defined less by blending targets and more by the depth of systemic reform across feedstock, infrastructure, and policy architecture.
