For some sectors of our economy, electrification as a decarbonization strategy is a whole lot easier said than done. Take the steel industry - which is responsible for 11% of global CO2 emissions. 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 a coal furnace, is an enormous challenge - but one that Boston Metals are taking the lead on.
Climate Now sat down with Adam Rauwerdink, senior vice president of Boston Metals, to better understand the landscape of developing clean steel technologies, and why the electrification process they are developing - “molten oxide electrolysis” - could be the decarbonization solution that the steel industry needs.
