Govt Exploring Isobutanol Blending with Diesel

The government is exploring isobutanol blending with diesel after ethanol-diesel blending trials failed.
The Automotive Research Association of India (ARAI) is conducting tests to ensure fuel compatibility and farmer income support.

Policy Cornerstone: Part of India’s biofuel roadmap to reduce oil imports & enhance farmer incomes.
Success in Petrol: India achieved 20% ethanol-petrol blending ahead of schedule.
Challenge in Diesel:
- Ethanol is corrosive.
- Engine compatibility issues prevented scaling up ethanol-diesel blending.
Farmer Impact:
- ₹42,000+ crore earned by farmers.
- Corn prices doubled (₹1,200 → ₹2,600–₹2,800 per quintal).
- Strengthened rural incomes.

What is it? Alcoholic compound (C₄H₁₀O), used in paints, coatings, food additives.
Advantages over Ethanol:
- Higher heating value (more energy).
- Less corrosive & less hygroscopic.
- Better engine compatibility with diesel.
- Can be blended at 10% with diesel.
Future Uses: Potential as standalone biofuel or in combination with CNG for tractors & agricultural machinery.

Govt cleared 96% sugarcane payments, reducing cane dues to record lows.
Encouragement to:
- Expand ethanol distilleries.
- Adopt 2G & 3G ethanol tech (bamboo, agri-residues).
- Diversify production for domestic + export markets.

Sugarcane FRP (Fair & Remunerative Price): Needs revision due to rising input costs.
MSP (Minimum Support Price): Unchanged since 2019 – industry demands upward revision.
Export Quotas: Call to increase permissible sugar exports by 2 million tonnes (2025-26 season).

Sugarcane output: ↑ 40% in last decade.
Sugar production: ↑ 58% in last decade.
ISMA Estimates: Gross sugar output at 9 million tonnes (2025 season), up 20% YoY.
Highlights the potential of bioenergy integration with India’s energy policies.
