Recent developments at British Steel have sent shockwaves through the industry, sparking concerns over potential job losses and the broader implications for the steel manufacturing sector. Steelmaking is set to return to Teesside following an announcement that it will be the location for one of British Steel's electric arc furnaces.About 250 people will make so-called "green steel" - named because the process is cleaner than a traditional blast furnace - at the company's plant in Lackenby, Redcar. British Steel has announced a £1.25 billion proposal to adopt electric arc furnace steelmaking in Teesside and Scunthorpe, where up to 2,000 people could lose their jobs due to the change.Steelmaking disappeared on Teesside in 2015, when SSI collapsed, ending generations of traditional steel manufacturing.The former blast furnace in Redcar, which had dominated the skyline on Teesside for more than 40 years, was demolished in November 2022.British Steel said its new furnaces could be operational by late 2025.The Chinese-owned company confirmed that it planned to replace them with two electric arc versions which can run on zero-carbon electricity, if it gets “appropriate support from the UK Government”.It would build one new electric arc furnace in Scunthorpe and another at its Teesside plant.These electric furnaces are much greener, but require a lot fewer workers to keep them going.
