Pittsburgh (KDKA) – On Friday, US Steel announced that it would abandon its $ 1.5 billion project to upgrade its steelmaking in Montvalley.
Local experts believe this could be part of the company’s commitment to reduce carbon by 2050 earlier this month.
“But it produces a lot of CO2,” explains Professor Christ Pistorius, co-director of the Steelmaking Research Center at Carnegie Mellon University.
“To make a ton of steel, we produce almost two tons of CO2 in the process,” Pistorius told KDKA’s money editor John Delano.
Carbon dioxide is a by-product of steelmaking in blast furnaces that use coke from coal. But that’s not the only way to make steel. US Steel recently purchased Big River Steel in Arkansas, which uses an electric arc furnace instead of a blast furnace.
“This is one of the newest steel production plants in the United States,” said Ron Ashburn, secretary general of the Steel Technology Association.
Environmentally, electric arc furnaces are less polluted than blast furnaces.
“Carbon emissions are reduced by a factor of 30 and energy consumed is reduced by a factor of 6,” says Ashburn.
Pistorius says he is not surprised that the company has discontinued plans to upgrade its blast furnace here.
“This is in line with US Steel’s goal of moving to carbon-neutral at a fairly ambitious pace by 2050, and is essentially carbon-neutral. That requires major changes,” said Professor CMU. say.
What does that mean for Montvalley?
Ashburn says US Steel’s announcement to shut down Clairton’s three coke batteries makes sense.
“In 1990, 57 blast furnaces were in operation in the United States. Today, there are 15 in 2021.”
“We are working on steelmaking in Montvalley for the next generation,” said Edgar Thomson Works of Bradock.
Whether it remains a blast furnace or converted to an electric arc furnace, Ashburn said, “I’m optimistic that Montvalley Works has the potential to become an economic power and will continue to do so.” Told.
Steel supporters say Congress should pass several versions of President Biden’s infrastructure plan to keep the factory up and running. It takes a lot of steel to rebuild American roads and bridges.
