At the Indira Gandhi Atomic Energy Research Centre (IGCAR) in Kapacam, Tamil Nadu, engineers have just witnessed a historic moment. As the valve opens, high-temperature process waste heat from the Fast Neutron Proliferation Test Reactor (FBTR) is precisely injected into a complex piping system. This is not an ordinary energy transfer, but the world's first successful coupling of the waste heat of a nuclear reactor with the copper chloride (Cu Cl) thermochemical cycle hydrogen production process. This potentially wasted heat energy is now being transformed into green hydrogen, known as the "ultimate energy of the 21st century," marking a groundbreaking step for India in the diversified application of nuclear energy.

Waste heat turned into green hydrogen

This project is led by the Mumbai Baba Atomic Research Center (BARC) for process research and development, and is currently the world's first hydrogen production demonstration facility that relies on fast reactor nuclear process waste heat operation. Unlike traditional hydrogen production methods, the core advantage of copper chlorine thermochemical cycle technology lies in its "small appetite and high efficiency". It requires a much lower operating temperature threshold than other thermochemical hydrogen production processes and can perfectly match the industrial grade waste heat generated by nuclear reactors. Through this method, the hydrogen production process completely eliminates dependence on fossil fuels, eliminates greenhouse gas emissions from the source, and truly achieves zero carbonization throughout the entire lifecycle.

Forty years to sharpen a sword

This milestone breakthrough is built upon IGCAR's over forty years of technological accumulation. Since its establishment in 1971, the center has been the cradle of fast neutron multiplication reactor technology in India. The fast neutron multiplication test reactor independently designed and constructed by it has not only maintained stable operation for more than 40 years, but also provided a solid test platform for fuel testing, special material research and development, and sodium cooled reactor supporting technology. It is the accumulation of massive amounts of data and the ultimate control over high-temperature engineering that have enabled India to build a complete fast reactor technology system and ultimately support this technological feat of nuclear thermal coupling.keywords:New energy information network

New Energy Blueprint

The completion of this demonstration device is not only a success in technical verification, but also a microcosm of India's energy strategy. As a key part of India's three-stage nuclear power plan, this technology provides imaginative space for the commercial application of the upcoming 500 MW prototype fast reactor (PFBR). Ajit Kumar Mohanti, Chairman of the Ministry of Atomic Energy, pointed out that nuclear energy has the dual advantages of stable power supply and high-temperature heating, and is an ideal choice to achieve energy independence and carbon reduction goals. With the continuous optimization of subsequent process parameters, this domestically developed system will provide a valuable 'Indian solution' for the large-scale and commercial implementation of global nuclear hydrogen production.Editor/Yang Meiling
