Future of Green Steel
Stegra Closes $1.6B Financing for Europe's First Hydrogen-Based Green Steel Plant
Key Points
Wallenberg Investments holds about 38.5% of the votes but only around 18.8% of the capital in Stegra HoldCo, underscoring the bloc's governance influence relative to its equity stake.
Stegra HoldCo controls more than 90% of Stegra's shares and votes, with Green Nexus Investment Holding owning the remaining shares and votes; the consortium largely owns Stegra HoldCo while Green Nexus remains tied to existing shareholders.
Second lien lenders, led by AIP Management, are participating as direct equity investors in the project, signaling a broader risk-sharing approach beyond traditional debt.
CEO Henrik Henriksson commented on the closed financing, stating: 'We are grateful for the support for the work we are doing in bringing near zero emissions steel to the market from both new and existing investors, as well as from lenders,' highlighting the emphasis on Sweden’s competitiveness and the project’s role in that effort.
The underlying technology is hydrogen-based direct reduction of iron ore (DRI) powered by renewable electricity, which can yield near-zero embodied carbon in steel, though scaling such hydrogen-based processes to industrial volumes remains a core engineering and financial challenge.
Swedish green steel startup Stegra has closed a €1.4 billion ($1.6 billion) equity financing round to finish building Europe's first large-scale hydrogen-based steel plant in Boden, northern Sweden, Reuters reported on June 24. The deal, led by a Wallenberg Investments-led consortium, unlocks a further €1.5 billion in previously blocked credit lines, bringing total capital raised to roughly €6.5 billion.
The closing follows an agreement in principle struck in April and received 100% approval from lenders — a rare outcome for a project of this risk and scale, according to Yahoo Finance. CEO Henrik Henriksson called it "a strong sign of confidence in our business case" from both new and existing investors.
Wallenberg Consortium Takes Control as Lifeline Closes
The new consortium — Wallenberg Investments, Temasek, IMAS, Bolero, and SEB-Stiftelsen — now holds a majority stake through a new holding company called Stegra HoldCo, which controls more than 90% of Stegra's shares and votes, according to Morningstar. Existing shareholders, including Altor, Hy24, and Just Climate, retained stakes through a separate vehicle called Green Nexus Investment Holding.
The Wallenberg bloc holds an outsized governance role: roughly 38.5% of the votes in Stegra HoldCo despite owning only 18.8% of its capital. Morningstar noted that analysts view Wallenberg's involvement as giving the project an "industrial pedigree" it previously lacked — shifting it from a startup into something closer to a national infrastructure project.
Project Faced Cost Overruns and a Doubled Funding Gap
The Boden plant was about 60% complete in late 2025 when Stegra revealed a funding shortfall. The gap started at roughly 10 billion SEK (about €870 million) but nearly doubled during negotiations as costs rose and Stegra took on extra infrastructure work, including logistics and power grid connections, according to Gasworld.
Several other European green steel projects were paused or cancelled in 2025 due to high electricity costs and investment hurdles. Stegra is now one of the few still standing. Second-lien lenders led by AIP Management went a step further than most creditors — they chose to invest directly as equity holders, sharing the project's risk rather than sitting behind a debt wall.
How Hydrogen Turns Iron Ore Into Near-Zero-Emission Steel
Traditional steelmaking burns coal to strip oxygen from iron ore, releasing huge amounts of CO2. Stegra's process uses green hydrogen instead — produced by a 700 MW electrolyzer, Europe's largest — releasing only water vapor. The result is steel with roughly 95% fewer carbon emissions than coal-based production, according to Yahoo Finance.
Scaling that process to industrial volumes is the core challenge. Phase 1 targets 2.5 million tonnes of green steel per year, with a goal of 5 million tonnes by 2030. The plant is expected to create 4,700 direct and indirect jobs in Sweden. CEO Henriksson said the project matters for "Sweden's competitiveness as an industrial nation."
Production Timeline Under Review as Commissioning Nears
Stegra had targeted a production start in late 2026, but the company confirmed the timeline is "currently under review" as it integrates new infrastructure plans, Morningstar reported. The production start date matters well beyond Sweden — analysts at LeadIT warned that a failure to commission would likely "curtail confidence" in hydrogen-based industrial decarbonization globally.
The EU's Green Deal Industrial Plan leans heavily on projects like Boden to show that hard-to-decarbonize sectors — steel, cement, chemicals — can cut emissions without permanent government subsidies. With €6.5 billion committed and lenders fully on board, Stegra has bought itself the runway to find out if that bet pays off.
