JFE may build electric arc furnace to replace blast furnace in west Japan

TOKYO — JFE Steel, Japan’s No.2 steelmaker, is considering building a new electric arc furnace (EAF) to replace the No.2 blast furnace at its Kurashiki plant in western Japan to reduce its carbon dioxide (CO2) emissions, a company spokesperson said on Monday.

The move comes as steelmakers around the world are under pressure to cut CO2 emissions to tackle climate change.

JFE Steel is studying the possibility of constructing an EAF that can cut CO2 emissions to a quarter of those of a blast furnace sometime between 2027 and 2030 when the No.2 unit is due for refurbishment, the spokesperson said.

Blast furnaces go through a refurbishment every 20 to 25 years.

JFE Steel, a unit of JFE Holdings Inc, has eight blast furnaces in Japan, including three at Kurashiki, but it is scheduled to shut one in eastern Japan by March 2024.

“We plan to maintain our annual crude steel output capacity of 26 million tonnes even if we switch one of the blast furnaces with an EAF,” the spokesperson said.

Japanese steelmakers, including Nippon Steel Corp, have been trimming capacity as they confront a period of waning demand as Japan’s population declines and because of growing competition from the world’s largest producer, China.

The Nihon Keizai Shimbun business daily said on Saturday JFE may spend at least several tens of billions of yen for the new furnace, but the spokesperson said no investment plan has been set as the company has just decided last week to start considering an EAF at Kurashiki.

CO2 emissions from the world’s steel sector will fall 30% by 2050 compared with 2021 as more mills turns to less-polluting electric furnaces, consultancy Wood Mackenzie said in May.

They predict around 48% of global crude steel will be made by electric arc furnaces by 2050, up from 30% in 2021 and almost on a par with blast furnace steelmaking. (Reporting by Yuka Obayashi; Editing by Christian Schmollinger)
