Indian steelmaker Tata Steel said it has started a trial for injecting hydrogen gas into its blast furnace at the company's flagship plant, in a bid to reduce the use of metallurgical coke and reduce carbon emissions.
The company began the trial injection at its plant in the eastern city of Jamshedpur, using 40 percent of the injection systems, Tata Steel said in a statement. "This is the first time in the world that such a large amount of hydrogen gas is continuously injected into a blast furnace," said the company, which aims to reach net zero by 2045.
The trial, which is expected to last four to five days on a continuous basis, has the potential to reduce coke rate by 10 percent, which translates into a 7 percent to 10 percent reduction in carbon dioxide emissions per ton of crude steel produced, it added.
The trial will provide insight into the use of blast furnaces with greener fuel injectors, 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 such as steel, to generate demand for cleaner fuel in its drive to reach net zero by 2070.
