History

Early Years (1904–1960)

Elkem was founded in 1904 by Norwegian engineer Sam Eyde, along with Knut Tillberg and the Wallenberg brothers, as Det Norske Aktieselskap for Elektrokemisk Industri, initially focused on harnessing Norway's abundant for electrochemical processes such as the Birkeland-Eyde method for producing synthetic fertilizers. In its formative years, the company rapidly expanded its operations by establishing several key plants in southern , including Arendals Smelteverk for silicon carbide production using imported German methods, as well as facilities for aluminum and calcium carbide manufacturing. These early ventures capitalized on local resources like and , laying the groundwork for Elkem's expertise in high-temperature . A pivotal development occurred in 1917 when Elkem acquired a plant in , later known as the Fiskaa works, which became central to its technological advancements. At this site, the company initiated production of the Söderberg , a self-baking, continuous system that revolutionized smelting by enabling stable operations at temperatures exceeding 2,000°C, particularly for aluminum production. The innovation, credited to engineers including Carl Wilhelm Söderberg, Mathias Sem, Gustav Jebsen, and Jens Westly, was patented in 1918 and quickly adopted for furnaces, enhancing efficiency in technology. Concurrently, during the 1910s, Elkem refined production processes at Arendals Smelteverk, applying the material in abrasives and refractories due to its hardness and thermal resistance. The period was not without significant challenges, particularly from the impacts of the World Wars. During , Elkem encountered shortages of raw materials, prompting collaborations with the Norwegian state to develop alternative processes. further exacerbated issues, with disruptions to raw material imports and energy supplies straining operations, though strategic contracts with U.S. firms like Reynolds Metals helped sustain the company through the 1940s. By the 1950s, Elkem had stabilized and expanded into production, culminating in the 1958 establishment of the aluminum plant in partnership with Alusuisse, marking a shift toward broader metallurgical capabilities.

Expansion and Mergers (1960–2010)

During the and , Elkem pursued strategic mergers to bolster its position in the ferroalloys sector. In 1972, Elkem merged with , a prominent Norwegian producer of and , forming Elkem Spigerverket and significantly enhancing Elkem's capabilities in ferrosilicon production. This merger integrated Christiania Spigerverk's established operations in , allowing Elkem to expand its domestic metallurgical output and diversify into steel-related alloys. The 1980s marked a period of aggressive international expansion through acquisitions, particularly in silicon and alloy facilities. Between 1981 and 1984, Elkem acquired several ferroalloys plants from , including operations in and , which strengthened its global footprint in metallurgical production.

In 2011, sold its Elkem subsidiary to China National Bluestar Group Co., Ltd., a subsidiary of state-owned National Chemical Corporation (), for USD 2 billion in an all-cash transaction that marked Elkem's transition to Chinese majority ownership. This deal, completed after regulatory approvals including from the , enabled Elkem to integrate with Bluestar's silicone operations and expand its Asian footprint, while retaining its Norwegian headquarters and operational independence. Efficiency initiatives that began with the 2006 closure of the Meråker plant in —part of a broader to consolidate production at more competitive sites—persisted into the under new ownership, emphasizing cost optimization and capacity rationalization without major additional shutdowns. These efforts shifted toward investments in high-efficiency technologies, such as systems at Chinese facilities acquired post-2011, supporting sustained profitability amid volatile commodity markets. Elkem returned to public markets with an initial public offering in March 2018 on the Oslo Stock Exchange, where shares were priced at NOK 29 and trading commenced shortly thereafter, raising approximately NOK 5.5 billion in gross proceeds. The capital influx funded the acquisition of two silicone production plants in China—Jiangxi Bluestar Xinghuo Organic Silicone and Bluestar Silicones—from parent company Bluestar, enhancing vertical integration and market position in the growing Asian silicones sector. Post-2020, Elkem navigated global disruptions including the and geopolitical tensions by bolstering through regional diversification, long-term supplier audits (achieving 100% coverage for raw materials in 2024), and integrated value chains in and to ensure operational continuity and mitigate demand fluctuations, such as delayed recovery in China's construction market. In alignment with energy transitions, the company advanced decarbonization efforts, including increasing biocarbon usage to 24% of reducing agents by 2024 (targeting 50% by 2031), launching a carbon capture pilot at its Rana facility with 95% CO2 capture efficiency, and securing renewable power contracts covering over 80% of Norwegian operations. These adaptations contributed to , with operating revenues reaching 33 billion in 2024 despite high energy costs and market volatility. In 2025, Elkem reported an EBITDA of 829 million for the third quarter, reflecting strong operational performance amid cost improvements. However, facing high costs and low , the company partially curtailed production at its plants in Rana, , and in October 2025.
