IIT Delhi researchers complete successful hydrogen production project

Researchers from IIT Delhi, in collaboration with the ONGC Energy Centre, India, have successfully generated clean hydrogen fuel from water at a low-cost.

IIT Delhi yesterday (8th Feb) shared details of the project, stating that those involved successful split water by a process known as sulphur-iodine thermochemical hydrogen cycle to generate low-cost, clean hydrogen fuel for industrial consumption.

Commenting on the achievement, Prof. Sreedevi Upadhyayula, Department of Chemical Engineering said, “There is an imminent need to switch over to renewable energy sources such as water.”

“The thermo-chemical hydrogen cycle for splitting water offers a practical means of generating hydrogen as a fuel and also oxygen as a by-product. Hence, it can be considered favourably for the commercial production of hydrogen on a large scale, in the near future.”

One of the challenges in the low-cost conversion taken-up by the IIT Delhi researchers in the project, was to design a suitable catalyst for the energy intensive, corrosive step of sulphuric acid conversion to sulphur-dioxide and oxygen.

The in-house catalyst developed met the criteria and is now patented. The modified iron oxide catalyst dispersed on silica surface on a silicon-carbide support catalyst is not only cost-effective and is also functional under the high temperature and corrosive conditions of the reaction.

“We have employed a combined state-of-the-art experimental and theoretical approach to design an efficient and cost-effective heterogeneous catalyst (for the sulphuric acid decomposition step of S-I cycle for hydrogen production) functional under high temperature, corrosive conditions while also being cost-effective,” Prof. Upadhyayula added.

“We have also demonstrated the entire integrated closed loop pilot plant level at IIT Delhi.”
