ARAI Explores Feasibility of Blending Isobutanol with Diesel to Achieve Net Zero Emission Targets
The Automotive Research Association of India (ARAI) is investigating the potential of blending isobutanol with diesel after previous attempts to blend ethanol with diesel proved unsuccessful. Isobutanol, an alcoholic compound with better properties than ethanol for diesel blending, can be produced from biomass such as sugarcane syrup and molasses using specially designed microbes. This initiative aligns with India's objective of reaching net zero emissions by 2070. While isobutanol offers advantages like higher flash points, challenges remain regarding its lower cetane number and potential impact on engine performance and 'diesel knock'.
Key Points
- Isobutanol is considered a superior alternative to ethanol for diesel blending due to its chemical compatibility.
- It can be produced from existing feedstock used for ethanol, such as sugarcane and grains, using engineered microbes.
- The pilot project for isobutanol blending is expected to take approximately 18 months to complete.
- If successful, India would be the first country in the world to commercially blend isobutanol with diesel.
Exam Facts
- India's target for net zero emissions is 2070.
- The pilot project for isobutanol blending is estimated to take 18 months.
- Isobutanol has a higher flash point than ethanol, making it safer for blending with diesel.
