HPCL is carrying out a pilot study on E27 fuel and diesel mixed with ethanol.

Preliminary studies on E27-fueled vehicles showed a marked reduction in CO and THC emissions compared to traditional gasoline.

Hindustan Petroleum Corporation Ltd (HPCL) has announced a groundbreaking pilot study on vehicles using E27 fuel and ethanol-blended diesel fuel. With this, HPCL becomes the first oil marketing company in India to initiate such a comprehensive research program, in line with the ‘Roadmap for Ethanol Blending in India by 2025’, which aims to promote the adoption of ethanol blending in gasoline (petrol).

The roadmap, designed to usher in a greener and more sustainable future, outlines a phased rollout plan for achieving 20% Ethanol Blended Gasoline (E20) by April 2023 and ensuring its widespread availability by April 2025. It further emphasizes the introduction of E20 material-compliant and E10 engine-tuned vehicles starting from April 2023, followed by the production of E20-tuned engine vehicles from April 2025.

Dedicated efforts are underway at HPCL state-of-the-art R&D Centre in Devanagunthi, Bengaluru for conducting comprehensive research on biofuels. The center’s proficient team is evaluating the effects and performance of different blends of ethanol-gasoline, ranging from 10% to 27%, as well as various blends of ethanol-diesel, on different categories of test vehicles at the Engine Research laboratory.

The pilot study of E27 fuel will focus on assessing its performance and emissions in engines and vehicles through extended mileage accumulation. Mileage accumulation of up to 10,000 km for two-wheelers and 20,000 km for passenger cars using E27 fuel is planned for this phase. Ethanol trials, in accordance with IS 1460:2017 fuel specifications, will also be conducted in conjunction with biodiesel-diesel.

Looking ahead, India’s next milestone in the Ethanol blending program is achieving 27% Ethanol blending beyond E20 fuel. With the success of the ongoing trials and the achievement of E27 fuel, India will proudly stand side by side with Brazil on the global platform in the Ethanol blending program.

HPCL successfully launched E20 fuel on February 6th, 2023, at 23 retail outlets (ROs) across the country. The current number of E20 ROs is 350, spread across 21 states in the country. The company has already reduced approximately 3000 MT of greenhouse gas (GHG) emissions to date. It is projected that by 2025, the use of E20 fuel will contribute to the reduction of more than 200 lakh MT of GHG emissions.
