IISc Bangalore has developed a new method of producing pollution-free vehicle fuel from organic waste

The price of petrol and diesel is increasing by leaps and bounds. But even more worrying is the fact that overuse of fossil fuels is driving global warming. The situation is getting out of hand day by day as the vehicles are driving emitting black smoke. 

Therefore, vehicles using non-polluting fuels like bio fuel, green hydrogen are running in the developed countries of the world. But the process of producing green hydrogen claimed as the clean fuel of the future is quite expensive.

To get rid of this problem, a group of researchers at the Indian Institute of Science (IISc) in Bangalore has developed a new type of technology, through which it is possible to prepare hydrogen from biomass or organic waste. The team is led by Professor S Dasappa of Center for Sustainable Technologies, IISc. He said, “Around 50 lakh tones of hydrogen are being used in various sectors across India. But most of it is produced from fossil fuels through the steam methane reforming route. Now we have found a way to produce green hydrogen from a completely unconventional energy source, organic waste.”

The process is divided into two steps – first, organic waste will be converted into 'syngas', a hydrogen-rich fuel gas mixture, using oxygen and steam as the noble reactants. After that, pure hydrogen will be produced from the syngas using a low-pressure gas generator made entirely by indigenous technology.

IISc Bangalore said in a statement, “This method is the most effective in the production of green hydrogen. With the help of this it is possible to make 100 grams of hydrogen from 1 kg of organic waste. This is because the steam used in this method also contains hydrogen, which participates in the homogeneous and heterogeneous reactions. " They also claim that this whole process of making green hydrogen is environmentally friendly.

It should be noted that green hydrogen produced from solar or wind power in the electrolysis method is also showing direction. Major industrialists of the country have already announced to invest in such alternative energy sectors. Again, Union Road Transport Minister Nitin Gadkari has suggested to take initiative in producing green hydrogen from canal water. Even he himself is experimentally using hydrogen fuel based electric car Toyota Miri.
