Nippon Steel's Green Pivot Hits Cost Wall

Nippon Steel, Japan's largest steelmaker, is facing major challenges in its plan to shift production to cleaner methods. The company wants to replace coal-burning blast furnaces with electric arc furnaces, which can use recycled scrap metal. This move is meant to cut carbon emissions. However, the company now says high electricity costs and expensive raw materials are creating "high hurdles" for the plan. Electric furnaces use huge amounts of power. In Japan, energy prices have risen sharply since the war in Ukraine. Another problem is the price and supply of high-quality steel scrap. Electric furnaces need this material to make certain advanced steel products. This type of scrap is currently limited and costly. The announcement shows how difficult it is for heavy industry to become greener. While the goal is to reduce pollution, the practical costs of clean technology can slow down change. Nippon Steel has not set a new timeline for its furnace replacement plan.
