- Hyundai announced a roughly $6 billion steel mill in Louisiana at a March 2024 White House ceremony with President Trump, pitched as supplying metal to the company's auto plants in Alabama and Georgia.
- The Louisiana plant, slated to begin operating in 2029, will initially run on natural gas with carbon capture — a setup Hyundai says can cut coal-based steel emissions by up to two-thirds but that still trails the zero-carbon green hydrogen the company had earlier described as a 'catalyst for the hydrogen ecosystem.'
- Hyundai Steel's U.S. subsidiary expects the facility to produce 2.7 million metric tons of metal per year on 1,700 acres, with South Korea's Posco investing $582 million for a 20% stake.
- Louisiana Economic Development negotiated a $2.6 billion incentive package using nondisclosure agreements signed by at least 10 Ascension Parish elected officials — a secrecy practice environmental groups are now suing to stop.
- Good Neighbors Louisiana won a concession from Hyundai to swap nine gas-fired heaters for electrified equipment but is still pushing for a binding community benefits agreement covering pollution, hydrogen use, and worker safety in a region locals call 'Cancer Alley.'
- The mill is the anchor of a planned 17,000-acre industrial hub called the RiverPlex MegaPark, even as earlier U.S. hydrogen-steel efforts by SSAB and Cleveland-Cliffs collapsed after they walked away from $500 million each in Biden-era federal funding.
Why it matters: Hyundai's Louisiana project crystallizes a national tension: the company is selling a frontier-green steel mill to Trump-era tariff politics while filing permits to use natural gas with carbon capture, leaving the hydrogen leap contingent on economics it can't yet confirm. For Donaldsonville and Ascension Parish — already saturated with petrochemical plants and ranked among Louisiana's poorest communities — the roughly $6 billion investment and $2.6 billion in state incentives are arriving behind NDAs, with no binding agreement on local hiring, pollution limits, or the timeline for a cleaner fuel switch.
