Iron & Steel — Sweden's Industrial Backbone
Sweden has been mining iron ore for over a thousand years. Viking-era bloomeries in Bergslagen produced the metal that forged Norse swords and tools. Today, that same geological inheritance underpins one of the world's most ambitious industrial transformations: the HYBRIT project, which aims to produce the world's first fossil-free steel using hydrogen instead of coal.
Between ancient heritage and green future lies a story of Arctic engineering, corporate ambition, and a country that has built its industrial identity on what lies beneath its ground.
LKAB is Europe's largest iron ore producer and is wholly owned by the Swedish state. The company operates primarily in the Malmfälten (ore fields) of Norrbotten county in Swedish Lapland, with its flagship mine beneath the city of Kiruna.
The Kiruna mine is the world's largest underground iron ore mine, with tunnels extending more than 1,365 metres below the surface. The ore body — a massive deposit of magnetite — has been mined continuously since 1898. But LKAB's most extraordinary current project isn't underground at all.
The Kiruna City Relocation
Mining activity has caused the ground beneath central Kiruna to subside. Rather than close the mine, Sweden has undertaken one of the most remarkable urban engineering projects in history: relocating the entire city centre — including the iconic Kiruna Church (voted Sweden's most beautiful building) — approximately three kilometres to the east.
The relocation, which began in earnest in 2014 and will continue into the 2030s, involves moving or rebuilding hundreds of structures, rerouting infrastructure, and creating a new city centre. The cost is primarily borne by LKAB, which has committed tens of billions of kronor to the project.

Rare Earth Discoveries
In January 2023, LKAB announced the discovery of Europe's largest known deposit of rare earth elements in the Kiruna area — over one million tonnes of rare earth oxides. These minerals are critical for electric vehicle batteries, wind turbines, and other green technologies. The discovery has significant geopolitical implications, as Europe currently depends almost entirely on China for rare earth imports.
SSAB — Pioneering Green Steel
SSAB is one of the world's leading producers of high-strength steel. Its products are used in everything from heavy vehicles and construction equipment to body armour and wind turbine towers. The company's Hardox brand is an industry standard for wear-resistant steel.
But SSAB's claim to global attention is HYBRIT.
HYBRIT — Fossil-Free Steel
HYBRIT (Hydrogen Breakthrough Ironmaking Technology) is a joint venture between SSAB, LKAB, and energy company Vattenfall, launched in 2016. The project aims to replace coking coal — traditionally used to reduce iron ore to iron — with hydrogen produced from renewable electricity.
Steel production accounts for approximately 7% of global CO₂ emissions. If successful at commercial scale, HYBRIT could eliminate virtually all carbon emissions from steelmaking. In August 2021, SSAB delivered the world's first fossil-free steel to Volvo Group — a milestone in industrial decarbonisation.
The roadmap: pilot plant operational (Luleå, 2020–2024), demonstration plant (2025–2026), commercial-scale conversion of SSAB's blast furnaces by 2030, full fossil-free steel production by 2035. The hydrogen will be produced using Sweden's abundant hydroelectric and wind power.

Boliden — Metals and Mining
Boliden is a major Nordic metals company specialising in copper, zinc, gold, silver, and lead. The company operates mines in Sweden and Finland and smelters in Sweden, Finland, Norway, and Ireland. Boliden's Aitik mine in Norrbotten is one of Europe's largest open-pit copper mines.
The company has a complicated legacy. The "Boliden case" — in which toxic waste from a Boliden smelter was exported to Arica, Chile, in the 1980s, causing severe environmental and health damage — remains one of Sweden's most high-profile corporate responsibility failures.
Historical Heritage
Iron and steel are woven into Swedish history. The Bergslagen region in central Sweden has been a mining district since at least the 6th century. By the 17th century, Sweden was one of Europe's leading iron producers, and Swedish osmundjärn (osmundized iron (bloom iron)) was a prized export across the continent.
The town of Falun, with its enormous copper mine (active from the 10th century until 1992), is a UNESCO World Heritage Site. The mine's by-product — Falu rödfärg (Falun red paint) — gives Sweden's iconic red wooden houses their distinctive colour.

Economic Impact
The mining and steel sector directly employs approximately 15,000 people in Sweden, with significantly more in related supply chains. The industry is concentrated in Norrbotten and Västerbotten counties in the north, where mining companies are often the dominant employers.
Iron ore and steel products are among Sweden's top exports. In 2024, exports of iron ore, iron, and steel exceeded SEK 80 billion. The sector's importance extends beyond revenue — it drives infrastructure investment, technical education, and research in materials science across Swedish universities and research institutions.
The Green Steel Opportunity
The convergence of HYBRIT, LKAB's rare earth deposits, and Europe's green transition agenda positions Sweden's iron and steel sector at the centre of a potentially enormous economic opportunity. As the EU's carbon border adjustment mechanism (CBAM) makes high-carbon steel imports more expensive, Swedish fossil-free steel could command a significant premium.
The question is execution. The technical challenges of hydrogen-based steelmaking at scale remain substantial, and the energy requirements are enormous — HYBRIT alone could consume as much electricity as Sweden currently uses for all rail transport. But if any country can pull it off, Sweden — with its abundant renewable energy, engineering expertise, and century-long mining heritage — has the strongest claim.
The industry that powered Sweden's rise as a European power in the 1600s may yet prove central to Europe's green industrial future.
