Tata Steel becomes the first Indian steel mill to produce hot-rolled steel for hydrogen transportation, while Welspun Corp is the first Indian pipe mill to produce Electric Resistance Welded (ERW) pipes for this purpose. This achievement aligns with India's green hydrogen policy and encourages the transition to a greener, more sustainable future.
ERW pipes are made by forming a flat strip of steel into a cylindrical shape and welding the edges together using electric resistance. The process involves passing an electric current through the edges, which generates heat and fuses them. This results in a seamless joint.
It was in 2022 when Tata Steel and Welspun Corp entered into a Memorandum of Understanding (MOU) to develop hydrogen-compliant API grade pipes through the ERW Pipe route. Tata Steel supplied hot-rolled coils for the project from its Kalinganagar plant in Odisha, while Welspun Corp manufactured ERW pipes. This strategic partnership aims to promote the usage of green hydrogen and contribute to a net-zero economy by 2070.
Last year in June, Tata Steel partnered with SMS group to implement the pioneering Paul Wurth Coke Oven Gas (COG) Injection Technology at their Blast Furnace in Meramandali, Odisha.
Last year Tata Steel initiated a trial, the first-of-its-kind globally, at its Jamshedpur Works, injecting a record-high quantity of hydrogen gas directly into one of its Blast Furnaces. Other initiatives include trials of continuous Coal Bed Methane (CBM) injection, operation of a 5-tonnes-per-day (TPD) industrial plant for carbon capture and utilisation since September 2021, increasing scrap charge in our blast furnaces and efforts to reduce freshwater consumption, develop sustainable supply chains and embrace circular economy principles.
