??How will Taiwan make its steel green?
Taiwan’s leading steelmaker China Steel Corporation (CSC) cannot finance the shift away from conventional coal-based blast furnace production to sustainable steelmaking by itself. While other countries invest huge amounts in the decarbonization of steelmaking, China Steel lacks the financial resources to go green. What can be done?
By Kwangyin Liu 劉光瑩 and 鄧凱元
At 67 Liu Shih-hsien, who has been responsible for developing technical solutions for the decarbonization of steel manufacturing at China Steel Corporation (CSC) for many years, now serves as consultant for hydrogen-fueled steel production.?
Today, he has already spent six hours watching over processes at an experimental plant in the southern port city Kaohsiung. Iron ore pellets resembling chocolate chips are placed into a three-meter-high blast furnace simulator. Then hydrogen, used to reduce the iron ore into iron, is slowly introduced into the furnace from the bottom. All eyes are on the reduction process as the technicians try to figure out the speed and temperature for optimal operations. “We are very cautious about feeling our way around,” explains Liu.
As fuels, hydrogen and coal behave very differently. Since hydrogen absorbs heat, it causes the temperature in the furnace to drop. In the worst case this could bring the entire reduction process to a halt, causing severe losses.
“Many technologies are not yet mature, walking toward net-zero is a very risky undertaking,” says CSC President Wang Shyi-chin.
CSC, founded in 1971, mainly produces hot-rolled steel products, cold-rolled steel, steel rods, and wire stock. In 2023 it generated consolidated revenue worth US$12 billion for an after-tax net profit of US$500 million.
The steelmaker’s difficulty to switch to an environment-friendlier production poses a challenge for Taiwan’s entire industry. CSC is not only the company with the highest number of shareholders but also one of the highest emitters of carbon dioxide in the world.?
At the Paris climate summit in 2015 a net-zero emissions target by 2050 was agreed among nations around the globe. Therefore, CSC is under pressure to reduce its carbon emissions, and low-carbon requirements have already become green trade barriers.
