ArcelorMittal zero-carbon emissions plant to use biomass, green hydrogen
The development is the result of a memorandum of understanding signed with the Spanish Government that will see an investment of €1 billion in the construction of a green hydrogen direct reduced iron (DRI) plant at its facility in Gijon, northern Spain, as well as a new hybrid electric arc furnace (EAF).
By 2025, the Sestao plant, which manufactures a range of flat steel products for the automotive and construction sectors, and general industry, will produce 1.6 million tonnes of zero carbon-emissions steel by:
- Changing the metallic input by increasing the proportion of circular, recycled scrap, and using green hydrogen-produced DRI from Gijon in its two existing EAFs;
- Powering all steelmaking assets (EAFs, rolling mill, finishing lines) with renewable electricity;
- Introducing several key emerging technologies that will replace the small remaining use of fossil fuel in the steelmaking process with carbon-neutral energy inputs, such as sustainable biomass or green hydrogen.
Central to this development will be the construction of a 2.3 million-tonne green hydrogen DRI unit in Gijon. Around 1 million tonnes of DRI will be transported to Sestao to be used as a feedstock for its two EAFs.
Aditya Mittal, CEO of ArcelorMittal, said: “It is widely understood that for the world to achieve net-zero by 2050, faster progress over the next decade is essential.
“Having announced a net-zero target for 2050, we, therefore, set ourselves the challenge to identify how we could take an existing steel plant to zero carbon emissions within the next five years.
“Our teams have been working incredibly hard to turn this ambition into the plan that we have announced today. This is a hugely significant development and demonstrates the strength of innovation embedded in our people, our unparalleled technology leadership, and what can be achieved through investment in existing steelmaking infrastructure.
“It means ArcelorMittal will be the first company in the world to be in a position to offer its customers meaningful volumes of zero-carbon emissions steel.”
Mittal added that the ability of the Sestao plant to become the world’s first zero carbon emissions steel plant would not be possible without the support of the Spanish Government.
“This is a project that will require the support of many different partners to succeed,” he said, “the plan hinges on the supply of affordable, mass-scale hydrogen, access to sustainable finance and a supportive legal framework that allows us to be competitive globally.
“The Spanish Government has embraced the opportunity and developed clearly defined plans to transition the country to having the energy infrastructure that the green economy will require.
“ArcelorMittal plans to switch Sestao to renewable electricity. This, together with the green DRI and hydrogen feeding the burners, will result in the Sestao plant achieving zero carbon emissions. We are also working to reduce Scope 3 emissions to zero.
“As a large emitter, the steel industry can make a vital contribution to achieving net zero by 2050. This project demonstrates what is achievable.”
