A new report by KPMG titled 'Beyond E20' suggests that India's ethanol transition is entering its next phase, where the fuel can evolve from a blending component into a potential transport energy backbone. This shift could help moderate the country's exposure to external price shocks in the global oil market.
Adaptive Fuel System and Flex-Fuel Vehicles
The consultancy firm highlighted that an adaptive fuel system, multi-grade distribution, and flex-fuel vehicles are critical to unlocking this role. Under low price environments with a supply glut, the system can remain anchored at baseline blending levels, allowing the fuel mix to benefit from favorable import economics while diverting ethanol to alternative pathways such as Sustainable Aviation Fuel.
When global oil supply tightens due to production cuts by OPEC and crude prices rise, ethanol can be redirected toward the transport fuel system to reduce exposure to higher import costs. This flexibility becomes even more critical during acute disruptions like the Russia-Ukraine conflict and recent geopolitical tensions involving Iran, where sudden supply constraints lead to sharp price spikes. The system's ability to scale ethanol utilisation through higher pool blends and flex-fuel pathways provides a mechanism to partially offset external volatility.
Foundation for Shift Already in Place
KPMG noted that the foundation for this shift is already in place. India has built capacity, supply chains, and distribution systems at scale through the Ethanol Blended Petrol programme. However, the next phase requires two structural shifts: expanding ethanol's role beyond blending and moving from uniform E20 distribution to a multi-grade ecosystem for E85/E100. This transition entails coordinated readiness across supply, demand, pricing, infrastructure, and vehicle technology.
Constraints Holding Back Higher Blends
Despite progress, the report flagged several constraints that hold back blends beyond E20. These include dependence on 1G food-linked feedstock, which limits scalability; E20 acting as a demand ceiling with supply beginning to exceed absorption; pricing rigidity in a cost-based framework; infrastructure not designed for multi-grade fuels; and limited penetration of flex-fuel vehicles.
Way Forward
To move forward, KPMG recommended that India diversify feedstock beyond 1G, evolve pricing toward a hybrid model that balances market alignment with stabilisation, enable infrastructure for multiple fuel grades, and strengthen the vehicle ecosystem through flex-fuel deployment and regulatory alignment.
'India has already established one of the world's largest ethanol ecosystems. The challenge ahead lies not in incremental scale-up, but in system-level evolution,' the report concluded. 'The opportunity is to transition ethanol from a successful blending programme to an integrated component of the transport fuel system, enhancing resilience, reducing exposure to external volatility, and strengthening long-term energy security.'
