BENGALURU, April 24 (Reuters) - Indian steel maker Tata
Steel Ltd on Monday said it initiated trial for
injecting hydrogen gas at its blast furnace in the company's
flagship plant, in a move to reduce metallurgical coke usage and
cut carbon emissions.
The company commenced the trial injection at the plant in
the eastern city of Jamshedpur, using 40% of the injection
systems on Sunday, Tata Steel said in a statement.
"This is the first time in the world that such a large
quantity of hydrogen gas is being continuously injected in a
blast furnace," the company, which aims to become net zero by
2045, said.
The trial, expected to continue for four to five days on a
continuous basis, has the potential to reduce coke rate by 10%,
translating into a 7% to 10% reduction in carbon dioxide
emissions per ton of crude steel produced, it added.
The trial will provide insights into operating blast
furnaces with greener fuel injectants, reducing fossil fuel
consumption and subsequent CO2 emissions from the blast furnace,
the company said.
The move to use hydrogen comes as India has set green
hydrogen consumption targets for some industries like steel, in
order to generate demand for cleaner fuel in its quest to reach
net zero by 2070.
