Tata Steel plans to meet 25% of energy needs via green sources – ET Infra


MUMBAI: Tata Steel, Asia’s oldest manufacturer of the primary infrastructure alloy, plans to meet at least a fourth of its energy requirements through green energy by FY30 on its path to become net neutral on carbon emissions by 2045.

It plans to do so using a mix of hydrogen injections and renewable energy including solar and wind at its plants across the country, Rajiv Mangal, vice president for safety, health and sustainability, Tata Steel, told ET.

Earlier this year, the company had successfully injected hydrogen at one of its blast furnaces in Jamshedpur, aimed at reducing carbon emissions by 7-10% for each tonne of crude steel produced.

“We wanted to test hydrogen because transportation of hydrogen is very costly and risky. So, we wanted to be sure. Those fears are now behind us, so we are looking at either a 15 tonne per day hydrogen plant, or someone else providing it to us,” Mangal said.

“The price of hydrogen in the market will not be less than $5 to $6 per kg. To be commercially viable in a steel plant, we need it in the range of around $1. So, hydrogen technically can solve the problem, but commercially cannot,” he said.

Production of steel is one of the most carbon-intensive processes globally, accounting for as much as 7-9% of carbon emissions. Conversations around the industry are increasingly turning toward how the production of steel can be made greener. This includes manufacturing steel through usage of scrap and replacing the conventional sources of energy with renewable power.

Tata Steel is also in a pact with Tata Power for renewable energy, which will be functional by FY25. This will include solar, wind and other forms of energy.

Simultaneously, the steel major is also planning a pilot at its Kalinganagar plant, where it will generate syngas that can be used as a replacement for coke in blast furnaces. The pilot is expected to be ready by February.

“It is an R&D project where we are using all the waste in the plant, including plastic to generate syngas, and it will be fed into the blast furnace as a replacement of coke,” Mangal said.

The company, which has also announced an electric arc furnace plant to be set up in Ludhiana in Punjab, will source the scrap needed for it from its collection and recycling centre in Rohtak, which currently processes about 40,000 tonne of scrap each month.

Tata Steel plans on setting up two more of such centres – one each in the southern and western parts of the country.

The company will also be setting up two more electric arc furnaces adjacent to these centres.
