A large part of those emissions come from the ‘coking’ process - where coal-fired furnaces burning at up to 1,100 degrees Celsius (2,000 degrees Fahrenheit) are used to break the bonds between iron and oxygen in the ore materials used to make steel. Driving this reaction with electricity, instead of...
