Path 1: Blast furnace to electric arc furnace (EAF) steelmaking
One common pathway steelmakers have undertaken is shifting from traditional blast furnace steelmaking to EAF, which uses renewable energy and more ferrous scrap and has proven to be less carbon intensive.
Path 2: The use of carbon capture technology
A second pathway is the use of carbon capture and storage technologies, which involve capturing emissions at steel plants before they escape into the atmosphere and storing them.
Japanese steelmaker Nippon Steel last year said it was studying this technology with multinational oil and gas corporation ExxonMobil and Mitsubishi Corporation.
The plan is to capture the emissions from the steelmaker’s plants in Japan and evaluate underground storage opportunities in Asia Pacific, such as in Malaysia, Indonesia and Australia.
Path 3: The adoption of green hydrogen-based technologies
The third and most explored pathway of decarbonization in Asia is the adoption of green-hydrogen-based technologies, which can effectively reduce carbon emissions and reduce the industry’s dependence on coal.
At least half of China’s leading steelmakers have started investing in these technologies to decarbonize their production, focusing on hydrogen-based iron (HBI) in steel production. fastmarkets
