India's biofuel drive is saving billions but also sparking worries
Summary
India has been using biofuels mixed with petrol to reduce carbon emissions and save money on fuel imports. This blending, especially with 20% ethanol known as E20, has reduced carbon emissions significantly and saved billions in foreign currency. However, there are concerns about its effect on fuel efficiency and possible impacts on vehicles not designed for E20 fuel.Key Facts
- India achieved its goal of blending 20% ethanol with petrol in 2023, five years earlier than planned.
- Ethanol blending has cut 69.8 million tonnes of carbon dioxide emissions since 2014.
- The program saved India 1.36 trillion rupees ($1.5 billion) in foreign exchange.
- Many Indian vehicles are not yet compatible with E20, raising concerns about engine efficiency and wear.
- Ethanol has lower energy density, meaning it provides less energy than petrol, potentially decreasing mileage.
- Solutions like E20 material kits and fuel cleaners are being offered by vehicle manufacturers to address issues.
- The federal petroleum ministry claims concerns about E20 are mostly unfounded and suggest simple fixes.
- As ethanol use expands, there might be increased competition for agricultural produce used for fuel production.
