South Korea’s “K-Steel Act,” designed to support the domestic steel industry’s transition to low-carbon production, is facing criticism from industry leaders for failing to include direct electricity rate reductions. While the legislation provides a framework for financial support and technological upgrades to meet carbon neutrality goals, steelmakers argue that the high cost of energy remains the primary barrier to implementing hydrogen-based steelmaking.
The legislation aims to protect the competitiveness of South Korean steel companies against global carbon regulations, such as the European Union’s Carbon Border Adjustment Mechanism (CBAM). However, industry representatives describe the current version of the act as a “half-success” because it focuses on investment subsidies rather than the operational cost of electricity, which is the most significant expense in the shift from blast furnaces to electric arc furnaces and hydrogen reduction iron (H-DRI) processes.
According to reports from South Korean industrial analysts, the transition to “green steel” requires a massive increase in electricity consumption to power electrolysis for hydrogen production. Without a specialized electricity tariff or significant discounts for carbon-neutral transitions, companies claim the financial burden will stifle the adoption of the very technologies the K-Steel Act intends to promote.
Why the K-Steel Act is viewed as a partial success
The K-Steel Act was conceived to provide a legal basis for the government to support the steel industry’s move toward carbon neutrality. Under the proposed framework, the government can provide subsidies for facility investments and R&D for low-carbon technologies. This is critical because the steel industry is one of the hardest-to-abate sectors in terms of greenhouse gas emissions.
The “half-success” label stems from the omission of electricity cost relief. In the hydrogen reduction process, electricity is used to produce hydrogen via water electrolysis. According to the Republic of Korea Government, achieving carbon neutrality by 2050 requires a systemic overhaul of the energy grid. Steelmakers argue that while subsidies help build the plants, the ongoing cost of electricity makes those plants economically unviable compared to traditional coal-fired blast furnaces.
Industry stakeholders point out that the current electricity pricing structure does not account for the “green premium” associated with hydrogen steel. Without a dedicated “industrial electricity rate” for low-carbon transitions, the cost of producing a ton of green steel remains significantly higher than that of traditional steel, threatening the global price competitiveness of Korean exports.
The role of hydrogen and carbon neutrality in steel production
Traditional steelmaking relies on coking coal to remove oxygen from iron ore, releasing vast amounts of carbon dioxide. The shift toward hydrogen reduction replaces carbon (from coal) with hydrogen, resulting in water vapor instead of CO2 as a byproduct. This process is the cornerstone of South Korea’s strategy to meet its Nationally Determined Contributions (NDCs) under the Paris Agreement.
To implement this, the government is focusing on the development of hydrogen-based direct reduction plants. However, the scale of electricity required is immense. For example, producing green hydrogen requires megawatts of renewable energy. If this energy is sourced from the general grid at standard industrial rates, the operational expenses (OPEX) outweigh the capital expenditure (CAPEX) subsidies provided by the K-Steel Act.
The discrepancy highlights a policy gap between the Ministry of Trade, Industry and Energy (MOTIE) and the actual operational needs of the steel mills. While the act establishes the “what” (low-carbon facilities), it has not yet solved the “how” (affordable clean energy).
Nuclear energy and the Wolsong-1 debate
As part of the broader energy strategy to lower electricity costs and ensure a stable power supply for the steel industry, there are renewed discussions regarding nuclear energy. Specifically, the potential restart of the Wolsong-1 nuclear power plant has emerged as a point of contention and a possible solution for energy stability.
Wolsong-1 was permanently shut down due to safety concerns and structural issues. However, some policy advocates argue that since extensive renovations and repairs have been completed, the government should re-evaluate its restart. The logic is that nuclear power provides the cheapest and most stable baseload electricity, which is essential for the energy-intensive electrolysis needed for green steel production.
This move is seen as a way to bridge the gap left by the K-Steel Act’s lack of electricity discounts. By increasing the supply of low-cost nuclear power, the government could theoretically lower overall industrial electricity rates, thereby indirectly supporting the steel industry’s carbon-neutral transition without needing a specific “discount” clause in the legislation.
What happens next for the Korean steel industry?
The immediate focus for the South Korean government is to refine the legal and institutional foundations of the K-Steel Act to address the energy cost gap. Industry groups are expected to continue lobbying for the inclusion of electricity rate supports or the creation of a “green energy zone” where steel plants can access cheaper power.
Furthermore, the Ministry of Trade, Industry and Energy will need to coordinate with the Korea Electric Power Corporation (KEPCO) to determine if a specialized tariff is feasible without violating fair-trade regulations or causing excessive deficits for the utility provider.
The next critical checkpoint will be the legislative review of the K-Steel Act’s implementing decrees, where specific subsidy amounts and potential energy supports are detailed. Additionally, the government’s official stance on the Wolsong-1 restart will serve as a signal for whether South Korea intends to rely on nuclear energy to fuel its industrial decarbonization.
