Steel Dynamics Inc. signed a renewable product purchase agreement (RPPA) with a subsidiary of NextEra Energy Resources for 308 megawatts of energy to be produced by a new wind-farm project in Scurry County, Texas. Once operational, the wind-farm project is expected to produce approximately 1.1 million MWh of electricity annually, equivalent to 16% of the Steel Dynamics’ EAF steel mills’ electricity usage in 2022. In addition, the deal is expected to contribute to the company’s long-term reduction of Scope 2 greenhouse-gas emissions.

ArcelorMittal and John Cockerill announced plans to construct what the companies say is the world’s first industrial-scale, low-temperature iron electrolysis plant. The Volteron plant, which in a first phase will produce between 40,000 and 80,000 metric tons a year of iron plates, is targeted to start production in 2027. Once the technology has been proven at this scale, the intention is to increase the plant’s annual capacity to between 300,000 and 1 million metric tons.

Tenova will supply an electric-arc furnace (EAF) equipped with a continuous scrap charging system and an electromagnetic stirring system to Posco for its Gwangyang plant in South Korea. The South Korean steelmaker, which produced approximately 43 million tons of steel in 2022, is gradually converting from the BF-BOF route toward electric steelmaking. After a two-year process of co-engineering and competitive comparison, Posco selected a full-platform EAF from Tenova capable of tapping 280 tons of liquid steel. The new EAF will be uniquely designed to match Posco’s needs of quality, productivity and efficiency and will include a full set of robotic applications and enhanced safety solutions.

NuScale Power Corp. and Nucor Corp. signed a memorandum of understanding (MOU) to explore co-locating NuScale’s VOYGR small modular nuclear reactor (SMR) power plants to provide clean, reliable baseload electricity to Nucor’s scrap-based electric-arc furnace (EAF) steel mills. The companies will also explore an expanded manufacturing partnership through which Nucor would supply Econiq, its net-zero steel products, for NuScale projects. As part of the MOU, the companies will evaluate site suitability, transmission interconnection capabilities and capital costs for potential NuScale plants to be sited near and provide carbon-free electricity to Nucor EAF steel mills.

Johnson Controls announced the launch of a program for recycling steel through a collaboration with Nucor Corp., the largest steel producer and recycler in North America. Over 70% of Johnson Controls’ steel purchases in the U.S. and 45% globally are manufactured from recycled scrap materials. The program with Nucor will recycle nearly 100% of that secondary scrap steel again, amounting to thousands of tons each year, at major Johnson Controls’ manufacturing sites in the U.S. Nucor will remelt the scrap steel using EAF technology, which generates approximately 75% less emissions than traditional blast-furnace manufacturing.

Liberty Steel, part of the GFG Alliance, announced the phase out of coal-based steelmaking at its Whyalla plant in Australia with the signing of a supply contract for a 160-metric-ton low-carbon electric-arc furnace (EAF) from Danieli. The new furnace will lift steelmaking capacity at Whyalla from 1 million metric tons per year to over 1.5 million metric tons per year. The EAF will initially be fed by domestic steel scrap and other iron-bearing materials to deliver an expected 90% reduction in direct CO₂ emissions compared with traditional blast-furnace production.

Tenova will supply an electric-arc furnace (EAF) with a production capacity of 950,000 tons of liquid steel for seamless pipe manufacturing to Tenaris’ Campana mill in Argentina. The EAF, which is equipped with Consteel technology and electromagnetic stirrer Consteerrer, will replace one of two existing EAF units and result in the same productivity of the two existing EAFs combined. In addition to the Consteel EAF, Tenova will provide engineering services.

Commercial Metals Company (CMC) acquired all the assets of metal recycling company Roane Metals Group LLC (Roane). Roane is capable of processing approximately 85,000 tons of ferrous and nonferrous materials annually at its two facilities in Tennessee. The majority of volumes relate to obsolete ferrous scrap grades consumed by CMC's long product mills. The acquired assets are expected to enhance the security and supply of competitively priced inputs to CMC's steelmaking operations.

Zinc Resources LLC, a processor of electric-arc furnace (EAF) dust, started operations at its new facility in Victoria, Texas. According to the company, it is the first EAF recycling plant to come online in the southern part of the United States in over 15 years and is also the first to receive approval from the Texas Commission on Environmental Quality (TCEQ) for recycling EAF dust in the state. Zinc Resources reduces the environmental impact of steel production by converting steel recycling waste into usable zinc and iron products. The location of the over $100 million facility, which is capable of processing 120,000 metric tons of EAF dust annually, provides logistical benefits to steel mills in the southwest. The company intends to employ a staff of roughly 50 full-time workers.

Ternium announced that it will integrate its operations in the North America region with a new electric-arc furnace (EAF) mill. The Luxembourg-based company will invest approximately $2.2 billion in the construction of facility in the USMCA (United States, Mexico, Canada) region to complement and support its hot-rolling mill in Pesqueria, Mexico. The EAF mill will have an annual capacity of 2.6 million tons, and it will include a direct-reduced iron (DRI) module with an annual capacity of 2.1 million tons. The project will also include the construction of a port installation to manage raw materials. Ternium expects the EAF mill to start operations in the first quarter of 2026.
