Principal scientific adviser to union government Dr R Chidambaram along with chairman & board members of IOCL flagged off the bus during the 47th foundation day function of Indian Oil R&D at Faridabad.

Hydrogen is considered to be the fuel of the future and using the fuel cell technology, very high efficiencies can be achieved with water as the only component in the exhaust. To be fuelled at nation's first hydrogen dispensing facility at R&D centre of Indian Oil, the vehicle would be subjected to long duration trials to understand the durability and efficacy of the fuel cell technology for mobility applications.
