POSCO Holdings — South Korea's Steel Giant Pivoting to Secondary Battery Materials and Green Hydrogen

POSCO Holdings — Corporate Profile

POSCO Holdings is South Korea’s largest steelmaker, one of the world’s top five steel producers by output, and an increasingly significant player in the global battery materials and green energy supply chain. Headquartered in Pohang, North Gyeongsang Province, with a major corporate presence in Seoul’s Gangnam district, POSCO Holdings reported consolidated revenue of approximately 77 trillion Korean won, roughly $58 billion, in 2024, with total assets exceeding 100 trillion Korean won. The company employs approximately 30,000 people directly and supports an extended supply chain ecosystem of hundreds of thousands of additional workers across South Korea’s industrial heartland.

Founded in 1968 as Pohang Iron and Steel Company with financial and technical assistance from Japan’s Nippon Steel, POSCO has grown from a single integrated steel mill into a diversified industrial conglomerate operating across steel production, trading, construction, energy, and advanced materials. The company’s transformation from state-owned enterprise to publicly traded corporation and its subsequent pivot from a pure-play steelmaker to a battery materials and green energy company represents one of the most consequential corporate reinventions in Korean industrial history.

POSCO’s strategic significance extends beyond its commercial operations. The company is central to South Korea’s ambition to dominate the secondary battery materials value chain, from lithium and nickel extraction to cathode and anode production, positioning Korea as an indispensable link in the global electric vehicle supply chain. Simultaneously, POSCO’s green hydrogen investments align with the national hydrogen economy strategy that targets hydrogen as a pillar of South Korea’s energy transition through 2030 and beyond.

Steel Production and Global Position

POSCO’s steel business remains the foundation of the company’s revenue and industrial significance. The company operates two of the largest integrated steel mills in the world: the Pohang Works in North Gyeongsang Province, which began production in 1973, and the Gwangyang Works in South Jeolla Province, which commenced operations in 1987. Together, these facilities produce approximately 40 million tonnes of crude steel annually, placing POSCO among the top five global steelmakers alongside ArcelorMittal, China Baowu Steel Group, Nippon Steel, and Ansteel Group.

POSCO’s steel product portfolio spans the full range from commodity hot-rolled coil to premium automotive steel, electrical steel for transformers and motors, and specialty stainless steel. The company’s World Premium Products strategy focuses on high-value steel grades that command price premiums over commodity steel and are less vulnerable to the chronic oversupply that has characterized the global steel market since China’s capacity expansion in the 2000s.

Automotive steel is a particularly important category for POSCO. The company supplies advanced high-strength steel and giga-steel products to Hyundai Motor Group and other global automakers for use in vehicle body structures that must meet increasingly stringent crash safety and fuel efficiency standards. POSCO’s GIGA STEEL brand, which includes grades with tensile strength exceeding 1,500 megapascals, has been adopted by major automakers for next-generation vehicle platforms including electric vehicle architectures that require lightweight yet structurally rigid body designs.

Electrical steel, used in the cores of transformers and electric motors, represents another high-growth segment for POSCO. The global expansion of renewable energy generation, electric vehicle production, and grid infrastructure creates sustained demand for grain-oriented electrical steel, a technically demanding product category where POSCO competes with Nippon Steel, JFE Steel, and ThyssenKrupp.

The Pohang and Gwangyang steel mills are located on the Korean coast with direct deepwater port access, enabling efficient import of iron ore from Australia and Brazil and export of finished steel products to markets across Asia, North America, and Europe. This logistical advantage, combined with decades of operational optimization, gives POSCO a cost competitiveness that sustains profitability even during cyclical downturns in global steel pricing.

Secondary Battery Materials Strategy

POSCO Holdings has undertaken the most aggressive pivot into secondary battery materials of any traditional steelmaker in the world. The company’s strategy targets the full battery materials value chain from raw material extraction through processing to cathode and anode active material production, with a stated goal of becoming one of the world’s top three battery materials companies by 2030.

The rationale for this pivot is both strategic and economic. South Korea is home to three of the world’s top six electric vehicle battery manufacturers, LG Energy Solution, Samsung SDI, and SK On, which together account for approximately 25 to 30 percent of global EV battery production. These companies require massive and growing quantities of cathode active materials, anode materials, lithium compounds, nickel sulfate, and cobalt compounds. POSCO’s entry into battery materials positions it as a domestic supplier to these battery giants, reducing Korea’s dependence on Chinese-controlled battery material supply chains.

POSCO Chemical, renamed POSCO Future M in 2023, is the subsidiary driving the battery materials strategy. The company produces cathode active materials including nickel-cobalt-manganese (NCM) formulations and lithium iron phosphate (LFP) for EV batteries, as well as synthetic and natural graphite anode materials. POSCO Future M operates production facilities in Gwangyang and Pohang, with capacity expansion plans that target 610,000 tonnes of cathode material and 320,000 tonnes of anode material annually by 2030.

The scale of POSCO’s battery materials ambition is matched by the capital commitment. The company has announced investment plans exceeding 40 trillion Korean won, approximately $30 billion, through 2030 for battery materials and related businesses. This figure rivals the investment commitments of the battery cell manufacturers themselves and reflects POSCO’s conviction that materials supply will be the binding constraint on global EV adoption through the 2030s.

Lithium Processing and Supply Chain

POSCO’s lithium strategy is one of the most comprehensive in the industry, spanning extraction, refining, and compound production across multiple continents. The company operates the first commercial-scale lithium hydroxide production plant in South Korea, located in Gwangyang, using a proprietary extraction technology that recovers lithium from spodumene concentrate and brine sources.

The Gwangyang lithium plant has a production capacity of 43,000 tonnes of lithium hydroxide per year, with plans to expand capacity to over 100,000 tonnes annually by 2030. Lithium hydroxide is the preferred lithium compound for high-nickel cathode materials used in premium EV batteries, and POSCO’s domestic production capability reduces the battery supply chain’s dependence on Chinese and Chilean lithium processors.

POSCO has secured lithium raw material supply through a portfolio of international investments. The company acquired a stake in lithium brine deposits in Argentina’s Salta province, where it is developing the Sal de Oro and Sal de Vida projects. In Australia, POSCO has invested in the Pilgangoora lithium mine through a joint venture with Pilbara Minerals, securing long-term supply of spodumene concentrate for its Korean processing facilities.

The company’s lithium strategy also extends to unconventional extraction technologies. POSCO has developed proprietary direct lithium extraction technology that can recover lithium from low-grade brine sources more efficiently than traditional evaporation ponds. This technology, if successfully scaled, could unlock lithium resources that are currently uneconomical to develop, providing POSCO with a technological moat in raw material supply.

Nickel Processing and Downstream Integration

Nickel is the other critical battery raw material where POSCO has made substantial investments. High-nickel cathode chemistries, which offer superior energy density and are preferred for premium EV applications, require large quantities of battery-grade nickel sulfate. POSCO has positioned itself as a major nickel processor through investments in Indonesia, which holds the world’s largest nickel reserves.

POSCO’s Indonesian operations center on a partnership with Chinese and Indonesian counterparts to develop nickel smelting and processing facilities on Sulawesi and Halmahera islands. The company operates a nickel pig iron smelting plant and is investing in high-pressure acid leaching facilities that produce mixed hydroxide precipitate, the intermediate product used to manufacture battery-grade nickel sulfate.

The Indonesian nickel investments connect POSCO to the world’s fastest-growing source of battery-grade nickel supply. Indonesia has leveraged its resource endowment and export ban on unprocessed nickel ore to attract tens of billions of dollars in processing investment, and POSCO’s presence in the country ensures access to nickel supply that might otherwise be captured by Chinese competitors.

In South Korea, POSCO operates nickel sulfate refining facilities that convert Indonesian intermediate products into battery-grade nickel sulfate for supply to domestic cathode manufacturers. This integrated supply chain, from Indonesian mine site to Korean cathode plant, exemplifies the vertical integration strategy that POSCO is pursuing across all critical battery materials.

Green Hydrogen and Energy Transition

POSCO’s green hydrogen strategy represents the company’s most ambitious bet on the energy transition. Steel production is one of the most carbon-intensive industrial processes, accounting for approximately 7 to 8 percent of global CO2 emissions, and POSCO’s own steel operations emit approximately 70 million tonnes of CO2 annually. The transition from coal-based blast furnace steelmaking to hydrogen-based direct reduced iron production is essential if POSCO is to meet its stated goal of carbon neutrality by 2050.

The company has announced plans to invest approximately 10 trillion Korean won in hydrogen and renewable energy infrastructure through 2030. This investment encompasses green hydrogen production using electrolysis powered by renewable energy, hydrogen distribution infrastructure, and the development of hydrogen-based direct reduced iron steelmaking technology that can replace coal-fired blast furnaces.

POSCO’s hydrogen strategy extends beyond its own decarbonization needs. The company envisions itself as a hydrogen infrastructure provider, supplying green hydrogen to industrial customers, hydrogen fueling stations for fuel cell vehicles, and hydrogen-derived products including green ammonia for shipping fuel and green methanol for chemical feedstock. This ambition aligns directly with the Korean government’s national hydrogen economy roadmap, which targets 3.9 million tonnes of hydrogen consumption annually by 2030 and positions South Korea as a global hydrogen hub.

The company has partnered with international energy companies to secure green hydrogen supply chains. POSCO has signed memoranda of understanding with Fortescue Future Industries of Australia, CF Industries of the United States, and Oman’s state energy companies to develop green hydrogen and green ammonia production and import infrastructure. These partnerships reflect the reality that South Korea’s limited renewable energy resources will require hydrogen imports to meet the scale of demand envisioned in the national hydrogen strategy.

POSCO’s Pohang steel works has been designated as a pilot site for hydrogen-based steelmaking, with plans to begin commercial-scale hydrogen direct reduced iron production in the late 2020s. The technical and economic challenges of this transition are enormous, as hydrogen-based steelmaking currently costs significantly more than conventional blast furnace production. However, the combination of carbon pricing mechanisms, green steel premiums from automotive and construction customers, and government subsidies may close the cost gap by the early 2030s.

Construction and Infrastructure

POSCO E&C, the group’s engineering and construction subsidiary, is one of South Korea’s major construction companies, operating across residential, commercial, industrial, and infrastructure projects. The company builds residential apartment complexes under the “The Sharp” brand, one of the most recognized apartment brands in Korea’s housing market where branded apartment developments command significant premiums over unbranded properties.

The construction division also undertakes major industrial projects including plant construction, port development, and energy infrastructure. POSCO E&C’s international construction portfolio includes projects across Southeast Asia, the Middle East, and Africa, where the company leverages its industrial engineering expertise to win contracts for steel plants, petrochemical facilities, and power generation projects.

The construction arm provides a natural internal customer for POSCO’s steel products, creating a vertical integration advantage similar to that enjoyed by other Korean conglomerates. Steel-intensive construction projects flow through POSCO’s integrated supply chain from blast furnace to building site, capturing margin at multiple stages of the value chain.

Financial Performance and Corporate Structure

POSCO transitioned from an operating company to a holding company structure in 2022, becoming POSCO Holdings with subsidiary operating companies including POSCO steelmaking, POSCO Future M for battery materials, POSCO International for trading, POSCO E&C for construction, and POSCO Energy for power generation. This restructuring was designed to create clearer separation between the mature steel business and the growth-oriented battery materials and energy businesses, enabling differentiated investment strategies and potentially differentiated valuation by the financial markets.

Revenue for the POSCO Holdings consolidated group has fluctuated with global steel prices and economic conditions. The company reported consolidated revenue of approximately 77 trillion Korean won in 2024, with operating profit margins in the mid-single-digit percentage range typical of integrated steelmakers. The battery materials business, while still a fraction of total revenue, is growing rapidly and commands higher growth premiums from investors.

POSCO Holdings is listed on the Korea Exchange and is one of the most heavily traded stocks among Korean industrial companies. The company’s American Depositary Receipts trade on the New York Stock Exchange, providing international investors with direct exposure to POSCO’s transformation story. The stock’s valuation reflects the market’s assessment of whether POSCO can successfully transition from a mature steelmaker to a diversified materials and energy company.

The company’s balance sheet has been strained by the simultaneous investment requirements of maintaining competitive steel operations, building battery materials capacity, and developing hydrogen infrastructure. Total capital expenditure plans through 2030 exceed 50 trillion Korean won across all business segments, requiring a combination of operating cash flow, debt financing, and potential equity capital to fund.

Role in Seoul’s Vision 2030

POSCO Holdings’ relevance to Seoul’s Vision 2030 operates primarily through the industrial and sustainability dimensions of the framework. While POSCO’s physical operations are concentrated outside Seoul in Pohang and Gwangyang, the company’s strategic decisions, made from its Seoul corporate offices, directly shape South Korea’s industrial competitiveness and energy transition trajectory.

The battery materials strategy connects POSCO to the EV supply chain that is central to Vision 2030’s technology ambitions. South Korea’s target of becoming a top-three global EV battery producer requires a domestic supply of cathode and anode materials at scale, and POSCO Future M is the largest Korean company addressing this supply gap. The joint investment commitment of 20 trillion Korean won through 2030 for advanced battery technologies, involving Samsung SDI, LG Energy Solution, and SK On, depends partly on the battery materials supply that POSCO provides.

POSCO’s green hydrogen investments align directly with the national hydrogen economy strategy that the Korean government has designated as a pillar of its energy transition. The target of establishing South Korea as a global hydrogen hub by 2030 requires companies like POSCO to develop both the production technology and the distribution infrastructure for green hydrogen at industrial scale.

The company’s automotive steel business supports Hyundai Motor Group’s EV production ambitions by providing the advanced high-strength and lightweight steel grades required for next-generation vehicle platforms. As Hyundai targets annual EV production of 2 million units by 2030, POSCO’s supply of automotive-grade steel and battery materials creates a reinforcing relationship between two of Korea’s largest industrial companies.

POSCO’s transformation from steelmaker to materials and energy company is a test case for whether Korea’s heavy industrial base can reinvent itself for the low-carbon economy. The success or failure of POSCO’s pivot will influence whether Seoul achieves its Vision 2030 goals of maintaining industrial competitiveness while meeting carbon reduction commitments under the Paris Agreement.
