Green Steel: Decarbonising with Hydrogen-Fueled Production
As the fight against climate change ramps up worldwide, the need for industries and economies to respond is immediate.
Of course, different sectors contribute different amounts of greenhouse gas (GHG) emissions, and face different paths to decarbonisation as a result. One massive player? Steel and iron manufacturing, where energy-related emissions account for roughly 6.1% of global emissions.
The following infographic by AFRY highlights the need for steel manufacturing to evolve and decarbonise, and how hydrogen can play a vital role in the “green” steel revolution.
The Modern Steel Production Landscape
Globally, crude steel production totalled 1,951 million tonnes (Mt) in 2021.
This production is spread all over the world, including India, Japan, and the U.S., with the vast majority (1,033 million tonnes) concentrated in China.
But despite being produced in many different places globally, only two main methods of steel production have been honed and utilised over time—electric arc furnace (EAF) and blast furnace basic oxygen furnace (BF-BOF) production.
Both methods traditionally use fossil fuels, and in 2019 contributed 3.6 Gt of carbon dioxide (CO2) emissions:
|Steel Production Method||Materials Utilised||CO2 Emissions (2019)|
|BF-BOF||Scrap, iron ore, coke||3.1 Gt|
That’s why one of the main ways the steel industry can decarbonise is (Read more...)
