Tata Motors, ISRO develop India's first Hydrogen Fuel Cell bus

Tata Motors and the Indian Space Research Organisation (ISRO) have developed Hydrogen-powered bus after several years of research. Similar to a CNG bus, Hydrogen in bottles at high pressure is stored at the top of the bus. This compressed hydrogen combines with the oxygen in the air to generate electricity and the only emission it develops is of course vapour.

This electricity is used to charge the battery to power the motor of the bus. A number of fuel cells are combined to form a fuel cell stack, which is placed in the rear module of the bus. ISRO and TML entered into a MoU in 2006 to design and develop an automobile bus using hydrogen as a fuel through fuel cell technology.

Tata Motors Research Centre (TMRC) premises were used for the design and development of fuel cell power system in cooperation with ISRO and DSIR support.  Tata Motors successfully completed design and development of Fuel Cell Power System for bus application starting from 20Kw to 120Kw with co-operation of ISRO.
