How hydrogen can decarbonize the steel industry — and what it will take

Iron and steelmaking account for a quarter of total industrial CO2 emissions and the route to a sustainable future isn’t as simple as switching to electric energy.

Industry sectors like steelmaking traditionally rely on fossil fuels to produce the intense heat and feed the chemical process needed to smelt iron ore. But switching from coking coal to a cleaner feedstock like hydrogen offers a solution that produces only harmless steam emissions.

Produced by electrolysis using surplus renewable energy, green hydrogen could be used to clean up the roughly two thirds of global steel output that currently rely on fossil fuels. Primetals Technologies, a Mitsubishi Heavy Industries (MHI) Group company, has developed a process that replaces fossil-fuel-powered blast furnaces with plants fueled by hydrogen, helping to decarbonize steelmaking.

Take a look at his infographic to discover the many applications of hydrogen in steelmaking and what’s needed for the industry to reach net zero emissions.
