An IIT Delhi team generated clean fuel hydrogen from water at low-cost.

The team, along with ONGC, split water by a process known as Sulphur-Iodine thermochemical hydrogen cycle to generate low-cost, clean hydrogen fuel for industrial consumption.

The thermochemical hydrogen cycle for splitting water offers a “practical means” of generating hydrogen as a fuel and also oxygen as a by-product.

One of the key challenges faced by the IIT Delhi researchers 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 meets these criteria and is now patented, and a process based on these is being developed and demonstrated in the Institute.
