In vast and diverse country like India, we would have to adopt multi fuel option based on many factors like fuel availability, running cost, capital cost (cost of vehicle), regulations or lack thereof , safety, total cost of ownership, governmental inclination based on external factors like current account deficits etc etc. So in next 10 years, I expect petrol, diesel, (kerosene and heavy fuel in rural areas) flexi fuel, CNG, hydrogen, hybrid and electric vehicles running on the road simultaneously.
Hence company like EKC have role to play in this ecosystem. To what extent they would be successful depends on how nimble they are to adopt to the changing customer demand (moving from automotive to industrial, from CNG to hydrogen, from steel to composites etc)
