LanzaTech and Primetals Technologies renew 10-year cooperation to advance industry transition to green steel

  • Cooperation to accelerate deployment of LanzaTech’s commercial carbon recycling technology for iron and steel industry and expand ecosystem of partners
  • Will enable more carbon recycling projects in the global iron and steel sector

LanzaTech, a leading carbon capture and utilization company, and Primetals Technologies today announce the signing of a renewed ten-year cooperation agreement to accelerate the deployment of integrated environmental solutions for the steel industry worldwide.

LanzaTech’s commercialized carbon recycling platform takes emissions from heavy industry, including from the steel industry, and transforms them into the building blocks to make fuels and chemicals. Primetals Technologies builds on over 60 years of innovation in metals production and leverages the combined portfolio of predecessors Mitsubishi-Hitachi Metals Machinery and Siemens VAI, founded in 1938. Today, Primetals Technologies represents one of the longest standing global suppliers bringing new technology to the steel sector.

Multiple solutions for green steel

The renewed commitment cements a shared strategy for advancing the metals industry’s green transition: Primetals Technologies’s focus on delivering multiple solutions for green steel combined with LanzaTech’s novel carbon capture and utilization (CCU) technology that turns waste to value. Under the previous agreement, the companies worked together on process integration and optimization of transforming steel emissions into commodity chemicals. Through this new 10-year agreement, Primetals Technologies and LanzaTech will enable more projects in the global iron and steel sector to adopt LanzaTech’s carbon recycling technologies.

“There is no single pathway for the steel industry to reduce its emissions, but a range of solutions can play a significant part in meeting national, regional, and even corporate net-zero goals,” says LanzaTech CEO, Dr. Jennifer Holmgren. “We are delighted to offer a solution at commercial scale today and to be working alongside a sector leader like Primetals Technologies to bring our technology to more industrial players around the world.”

Converting emissions

Together, the companies have already collaborated with ArcelorMittal, one of the world’s leading steel companies, to deploy LanzaTech’s technology at ArcelorMittal’s flagship steel plant in Ghent, Belgium. The ArcelorMittal Steelanol project will convert the emissions from the blast furnace into advanced ethanol that can be used to make sustainable fuels and other downstream products—a first of its kind for the European steel industry.

Inaugurated in December 2022, this facility commenced operation at the end of May 2023, and the first samples produced were shown at a joint LanzaTech-Primetals Technologies event at METEC, the largest metallurgical trade fair in Düsseldorf, earlier this month. Once the Steelanol facility reaches full commercial-scale operations, it will have the capacity to reduce carbon emissions by 125,000 tons and produce 80 million litres of advanced ethanol annually.

The net-zero target

“The steel sector’s goal to achieve net-zero by 2050 depends upon breakthrough CCU technologies as they evolve,” said Dr. Alexander Fleischanderl, SVP and Head of Green Steel at Primetals Technologies. “Even as steel plants transition to new production methods, LanzaTech’s approach can utilize a variety of gas streams without any noticeable alterations to equipment or technology. If a steelworks decides to move on from today’s more carbon-intensive production route to newer processes, LanzaTech’s technology will still integrate with the resulting new gas streams. This flexibility is tremendously exciting for the future of the industry.”
