Hydrogen Harvesting

The slag granulation or quenching processes commonly used for slag cooling are not environmentally friendly and the heat contained in the molten slag is wasted.

Tata Steel has developed a novel process to generate hydrogen-rich gas by utilising the heat of molten slag. This process was demonstrated on a pilot project basis using a set up with 10 tonnes slag capacity, designed and developed in-house with the help of Tata Growth Shop, producing gas that contains over 70% hydrogen. International and Indian patent applications have been filed and work is now in progress to optimise the process for commercialisation at the Ferro Alloys plant.

This novel process has the potential to generate low cost hydrogen which can save energy and reduce the consumption of fossil fuels in the steel plant.
