Automobile industry blamed for stalling ethanol push

THE ETHANOL CONUNDRUM - Part - 3
Ethanol producers raced ahead of targets, but engine upgrades lag

Kolhapur: The current crisis confronting India’s ethanol industry is increasingly being attributed to the automobile sector’s sluggish pace in upgrading vehicle engines. The Centre’s ambitious ethanol blending programme rested on two pillars — ethanol production and vehicle manufacturing. While the ethanol industry surged ahead, meeting targets well before schedule and expanding capacity aggressively, the automobile sector failed to match that momentum. The resulting mismatch has pushed the ethanol ecosystem into serious difficulty.
India’s vehicle population continues to grow rapidly, to the point where even an expansive national highway network appears inadequate. There is little doubt that demand for ethanol-blended fuel will rise further in the coming years. However, parallel reforms in vehicle technology did not keep pace with the rapid scale-up in ethanol production, creating today’s bottleneck.
Linked Technology
The use of ethanol-blended petrol and the need for compatible engine technology are intrinsically linked. Conventional engines have coped reasonably well with petrol blended with up to 20 per cent ethanol. Beyond that threshold, engine modifications become unavoidable. The absence of such upgrades has triggered mixed reactions among consumers, with complaints surfacing about engine-related issues linked to higher ethanol blends.
Against this backdrop, ethanol producers have urged the government to raise the blending level by at least another two percentage points to absorb surplus supply. However, reliable sources indicate that the Centre is reluctant to move further, given the technical concerns associated with existing vehicle engines.
Brazil offers a stark contrast. The country has used ethanol-blended fuel for decades and routinely operates vehicles on blends as high as E80. This has been possible because E80-compatible and flex-fuel engines are widely available. In India, despite being one of the world’s largest automobile markets, manufacturers have been slow to embrace this transition.
While notable progress has been made in two-wheeler manufacturing, the sector continues to flag gaps in supporting infrastructure. In passenger vehicles, Maruti Suzuki has so far introduced the country’s first flex-fuel model, but the overall rollout remains limited. Industry watchers say the Centre will have to push the automobile industry harder — possibly through stricter regulatory timelines — to get it aligned with national biofuel goals.
Extended Delay
The consequences of this delay extend beyond ethanol producers. Pollution reduction efforts remain in limbo, both the sugar and ethanol industries are under strain, public investment risks remaining locked in, and potential savings in foreign exchange from reduced fuel imports are at stake.
In the interim, a possible middle path lies in the adoption of flex-fuel conversion kits. Such kits, already available in global markets, cost around Rs 15,000 on average. Promoting domestic manufacturing of these kits under the ‘Make in India’ programme could help bring costs down. If deployed at scale, they could mitigate engine-related issues associated with higher ethanol blends.
Until the automobile industry scales up production of flex-fuel vehicles, flex-fuel kits could offer a practical stopgap. Making flex-fuel engines mandatory in the future, industry experts argue, may be the only way to permanently resolve the crisis facing India’s ethanol sector.
To address the ethanol surplus, the Centre should consider providing export-linked subsidies that allow Indian ethanol to compete with global prices and reduce excess stocks. At present, maize-based ethanol receives an incentive of Rs 5 per litre. With a modest additional support, exports could become viable.
Beyond this, if India succeeds in scaling up domestic biofuel use while emerging as a major ethanol exporter, it could reap significant gains through carbon credits. This would require the government to establish a dedicated institutional mechanism to monetise such benefits. Dr Desai also underlined the need to strengthen infrastructure support for two-wheeler manufacturers that have made substantial advances in ethanol-compatible engine technology.
