Bengaluru: For the first time in the country, a Hydrogen-powered bus has been developed by Tata  Motors and Indian Space Research Organisation (Isro) after several years of research.The hydrogen fuel-fitted bus was demonstrated at Liquid  Propulsion Systems Centre, an Isro facility in Mahendragiri in  Tamil Nadu on Sunday.
It’s a CNG-type bus. Hydrogen in bottles at high pressure  is stored at the top of the bus and there would be zero  pollution. “This is a leap for automobile industry for future  transportation. In this vehicle there will be zero pollution  since the product of cold combustion is water. This is a  result of great team work of Tata Motors and ISRO specialists  with contributions from DSIR (Department of Scientific and  Industrial Research) and PESO (Petroleum and Explosive Safety  Organisation),” said honorary adviser to Isro, V. Gnana Gandhi, who  led the technical team in this project.
The team ensured all safety measures for handling hydrogen  in the bus. This development could help India to save considerably on crude oil imports.
According to a government-appointed committee led by Dr Kirit Parikh, trucks accounted for 37 per cent of the total diesel consumption in 2008-09, followed by buses 12 per cent and agriculture at 12 per cent.
As hydrogen is emerging as a leading contender for the ideal  energy options of the future, Gandhi said that the Union government has set guidelines for automotive companies over the development and  deployment of hydrogen-fueled vehicles by 2015.
“This R&D is the first endeavour in India, which  will put the nation in a select club of countries, which use hydrogen fuel cell driven buses and will eliminate pollution,” Gandhi said.He added that most of the city buses in the tier-1 cities are expected to run using  available hydrogen from fertiliser plants and oil refineries.
The hydrogen cells were a spin-off of the cryogenic  technology that Isro had been developing for the last few  years, the Benga-luru-based Isro officials said. “That’s not exactly the cryogenic technology... (It’s)  liquid hydrogen handling and that’s where Isro has some  expertise,” they said.
Isro has a very rich technology in producing, storing and handling gaseous and liquid hydrogen in the last three  decades. Its expertise is also in safety.
Isro and Tata Motors had entered  into an MoU in 2006 to design and develop a bus  using hydrogen fuel cells.

I want to begin with a little story that was told to me by a leading executive at Aptech. He was exercising in a gym with a lot of younger people.

Shekhar Kapur’s Bandit Queen didn’t make the cut. Neither did Shaji Karun’s Piravi, which bagged 31 international awards.
