Hyundai Steel Starts Louisiana Electric Arc Furnace Project

In the global steel market where the barriers of protectionism are rising day by day, the Korean steel industry is making a head-on breakthrough through direct investment in the United States. The long-cherished desire of the domestic steel industry to establish a ‘comprehensive production base in the US’ has entered a full-scale countdown.

According to the steel industry and foreign media on July 6 (local time), the mega electric arc furnace steel mill project that Hyundai Steel is building in Louisiana, US, has completed administrative procedures and investment structure reorganization, and will hold its official groundbreaking ceremony on Sept. 4. The strategic decision of Hyundai Motor Group to proactively respond to global trade disputes and high-tariff risks has finally materialized.

The newly constructed ‘Hyundai Steel Louisiana LLC’ is a mega project with a total investment reaching $5.8 billion (about 8 trillion won). In particular, this project is drawing extraordinary attention from the industry as POSCO, the eternal rival and partner of the Korean steel industry, participates by investing a 20% stake (about $580 million), making it a ‘strategic joint venture’ where the two giants representing K-Steel have joined hands within US territory.

Why Louisiana?: The Appeal of ‘Half-Price Electricity Rates’ and a Natural Gas Hub

At the core background of Hyundai Steel ultimately selecting the southern state of Louisiana among numerous candidate sites in the US lies ‘energy geopolitics’ and overwhelming cost competitiveness.

Electric arc furnace steel mills, which melt steel to produce products, entail massive power consumption. For Hyundai Steel, which has been spending over 1 trillion won ($666 million) in annual electricity bills domestically, the cheap energy infrastructure of Louisiana was an irresistible card. Louisiana is the center of the shale gas revolution in the US and a key liquefied natural gas (LNG) export hub. Because power generation is based on abundant and cheap natural gas, the industrial electricity rates here do not even reach half of the domestic industrial rates.

The advantages in terms of logistics and supply chain are also clear. Located in the lower reaches of the Mississippi River, it facilitates the import of raw materials and inland transportation of products, and boasts high accessibility to the group’s finished car production bases concentrated in the southern region, such as the Hyundai Motor Alabama plant, the Kia Georgia plant, and the newly operational Hyundai Motor Group Metaplant America (HMGMA).

The First-Ever Electric Arc Furnace Integrated Process in the US, Producing Low-Carbon, High-Quality Steel Plates in the Era of Carbon Neutrality

The Louisiana steel mill aims for commercial production in 2029, and will be equipped with a total annual steel product production capacity of 2.7 million to 2.8 million tons. The greatest technical characteristic of this plant is that it is the ‘first-ever electric arc furnace integrated steel mill in the US’ where everything from raw material input to final product production takes place all at once.

The traditional blast furnace method uses iron ore and coal, emitting a large amount of carbon dioxide, but the Louisiana plant, which adopted the electric arc furnace method, can drastically reduce carbon emissions compared to existing blast furnaces. It is an eco-friendly production base capable of simultaneously meeting the US administration’s moves to introduce a carbon border tax and the demands of global finished car manufacturers to achieve ‘RE100 (100% Renewable Energy)’.

The core product to be produced here is ‘top-tier low-carbon automotive steel plates’. Until now, the prevailing perception was that producing high-quality automotive exterior panels was impossible because electric arc furnace products are made by melting scrap metal, making impurity control difficult. However, Hyundai Steel plans to directly produce high-tensile automotive steel plates and lightweight materials exclusively for electric vehicles locally, which do not fall behind blast furnace products, by equipping proprietary advanced scrap refining technology and state-of-the-art automated process control systems.

Tariff-Free Benefits and the Seismic Shift in the North American Automotive Steel Plate Market

When the Louisiana steel mill goes into full-scale operation in 2029, a massive seismic shift is expected across the global steel and automotive industries.

First and foremost, the US steel quota barrier of high tariffs reaching 50% will be neutralized. In a situation where the export path of Korean steel materials to the US is stagnating due to trade regulations, Hyundai Steel’s products, having acquired the ‘Made in USA’ status, will receive tariff-free benefits and further elevate their price competitiveness.

The paradigm of the North American automotive supply chain will also change. Hyundai Motor and Kia can stably receive locally produced low-carbon automotive steel plates, perfectly meeting the local parts procurement requirements of the US Inflation Reduction Act (IRA), while simultaneously maximizing logistics cost savings and inventory management efficiency. Coupled with the distribution network of POSCO, which possesses a steel processing network across North America, the premium steel plate sales network targeting not only Korean finished car makers but also the local US Big 3 finished car manufacturers such as General Motors (GM), Ford, and Stellantis is expected to expand rapidly.

It is not all rosy prospects. Recently, a backlash movement has been emerging from local environmental groups and some residents raising the possibility of regional environmental pollution and labor environment issues due to the construction of the electric arc furnace plant, making thorough localization strategies and communication an urgent task ahead of the full-scale groundbreaking. Stably controlling the burden of raising initial large-scale investment funds of about 9 trillion won ($6.92 billion) due to the prolonged global steel economic recession is also a homework for Hyundai Steel’s management.

Nevertheless, experts are confident that this Louisiana investment will become a crucial turning point that shifts the paradigm of the Korean steel industry toward global localization and eco-friendliness.

A researcher at a large securities firm forecasted, “It is deeply meaningful in that they found a breakthrough for growth locally in the US, the world’s largest automotive market, amid stagnant domestic steel demand, and that they preemptively transitioned the high-carbon structured steel industry to a low-carbon electric arc furnace system,” adding, “If they wisely manage ESG risks such as initial mutually beneficial cooperation with local residents and compliance with environmental standards, Hyundai Steel will leap beyond a simple domestic steelmaker into a global top-tier eco-friendly steel company commanding the North American market.”
