India explores isobutanol as a cleaner diesel alternative for tractors and construction machines, supporting sustainable fuel and emission goals.
Isobutanol may replace diesel in tractors, harvesters, and machines.
Offers higher energy, less engine wear, and diesel compatibility.
Govt in talks with OEMs to test fuel use in the construction sector.
Startups are piloting biofuel and electric solutions for agriculture.
Supports biofuel targets under India’s clean energy policy.
India is taking a new step towards clean energy by exploring isobutanol as a possible replacement for diesel in construction equipment and agricultural machinery. This includes machines like tractors, harvesters, and heavy-duty vehicles, which are major users of diesel fuel today.
Isobutanol is a type of biofuel made from ethanol through fermentation. It is gaining attention because it offers several benefits over traditional fuels:
More energy-efficient than ethanol
Less corrosive, which helps protect engines
Compatible with diesel, either as a blend (up to 10%) or even full replacement
Because of these features, isobutanol can work well in internal combustion engines, including those used in farming and construction.
The Ministry of Road Transport and Highways is in talks with construction equipment manufacturers to study whether current diesel engines can run on isobutanol. This comes at a time when diesel still dominates the sector, increasing emissions and fossil fuel dependency.
A major meeting is planned with OEMs (Original Equipment Manufacturers) and suppliers to explore the switch to isobutanol in construction machines.
JCB India – experimenting with hydrogen-powered machines
SANY India and Schwing Stetter – adopting electric powertrains
ZF Group – expanding fuel-flexible components in India
The plan also includes the large agricultural sector, where tractors and harvesters still run mostly on diesel. The government is encouraging trials to use isobutanol and ethanol as fuel for these machines.
Goal: Test and introduce bio-based fuels in tractors
Current Progress: Startups are already running pilot projects
Challenge: Electric tractors do not receive subsidies under FAME or PM-eDrive schemes
Interestingly, some startups are also adapting electric tractors for biowaste management, showing their use beyond farming.
This move fits well into India’s long-term clean fuel goals under the National Biofuel Policy, which aims for:
20% ethanol blending in petrol
5% biodiesel blending in diesel by 2030
Reduce imported fuel dependency (Diesel usage was 91.4 million tonnes in 2024–25)
Promote clean air and sustainable energy
By 2025–26, diesel use is expected to rise by 3% to 94.1 million tonnes, making the need for cleaner alternatives more urgent.
Experts say that India is in a good position to adopt biofuels due to the availability of raw materials like sugarcane and corn, which are used to make ethanol and isobutanol.
Fossil fuels are also expensive to import, and agriculture plays a key role in India’s economy, making biofuel a smart alternative for rural and industrial use.

India’s efforts to explore isobutanol for tractors and construction machines show a smart and science-based approach to reducing emissions. As the country looks for cleaner and more affordable energy, isobutanol could become a key fuel to power farms and build infrastructure in a sustainable way.
With multi-fuel strategies under discussion and technology trials underway, the future of clean energy in off-highway sectors like farming and construction looks more promising than ever.
