For the first time in the country, hydrogen has been produced in a cost-effective process at a very large scale. Researchers and scientists around the world are working towards renewable energy solutions to produce hydrogen. A senior officer of the Department of Science and Technology said that this significant achievement by scientists from the Institute of Nano Science and Technology (INST) is expected to pave a way to produce hydrogen in a long term sustainable process.
The country has already set a target of 450 GW of renewable energy by the year 2030 and so one of the most effective ways to achieve this milestone is to produce hydrogen at a large scale through scientific process of photocatalytic water splitting.
Dr. Kamalakannan Kailasam is the team leader of INST scientists who developed this photocatalytic converter. He said, “It is the long-term persistent solution for the growing renewable energy needs and a low-cost economic process which will benefit society in the longer term. Thus significant efforts from scientists towards achieving this goal are the utmost necessary and urgent need-of-the-hour.”
Dr. Kailasam's team has developed a prototype reactor which works under sunlight to produce hydrogen at a larger scale and produces around 6.1 L in 8 hours. For the process they have used an earth-abundant chemical called carbon nitrides as a catalyst.
The Hydrogen which is generated by this process can be used in many forms
It can be used for electricity generation through fuel cells in the remote tribal areas, for powering small gadgets etc.
In the near future they can be used to power the transformers and e-vehicles.
