Understanding the Urgency of Steel Industry Decarbonization

The environmental impact of the steel industry is undeniable. Traditional steelmaking methods, primarily relying on blast furnaces fueled by coal, generate enormous amounts of CO2. This unsustainable practice significantly contributes to climate change and necessitates urgent action.

The Environmental Impact of Traditional Steelmaking

• CO2 emissions from coal: Coal-based blast furnaces are responsible for a substantial portion of global CO2 emissions.
• Environmental regulations: Stringent environmental regulations are increasingly targeting carbon emissions from industrial processes, pushing for decarbonization.
• Carbon taxes: Many countries are implementing carbon taxes, making traditional steel production more expensive and less competitive.
• Climate change goals: Meeting global climate change goals requires a dramatic reduction in CO2 emissions across all sectors, including steel production.

Traditional steelmaking involves the reduction of iron ore using coke (derived from coal) in a blast furnace, a process that releases large quantities of CO2 into the atmosphere. The World Steel Association estimates that steel production accounts for approximately 7% of global CO2 emissions. This staggering figure highlights the urgent need for a transformation of the steel industry.

The Growing Demand for Green Steel

The demand for green steel, or low-carbon steel, is rapidly increasing due to several factors:

• Corporate sustainability initiatives: Companies are increasingly incorporating sustainability into their operations, seeking to reduce their environmental impact through responsible sourcing.
• Government policies promoting green steel: Governments worldwide are introducing policies and incentives to encourage the development and adoption of low-carbon steel production technologies.
• Consumer demand for eco-friendly products: Consumers are becoming increasingly aware of the environmental impact of their purchases and are demanding more sustainable products.
• ESG investing: Environmental, Social, and Governance (ESG) factors are playing an increasingly important role in investment decisions, driving demand for companies committed to sustainability.

Sustainable procurement practices are becoming the norm, with companies prioritizing suppliers who can demonstrate a commitment to reducing their carbon footprint. This shift in market dynamics is further accelerating the transition towards green steel.

Eramet's eraLow: A Revolutionary Approach to Low-Carbon Steel Production

Eramet's eraLow process offers a revolutionary approach to steel production, significantly reducing its carbon footprint compared to traditional methods.

The Technology Behind eraLow

Eramet's eraLow is based on the direct reduction of iron ore using hydrogen, a process that eliminates the need for coal-based blast furnaces.

• Electrolysis: The process utilizes electrolysis to produce green hydrogen, powered by renewable energy sources.
• Hydrogen reduction: Hydrogen acts as the reducing agent, reacting with iron ore to produce iron, with water as the primary byproduct.
• Renewable energy integration: The entire process is designed to integrate renewable energy sources, minimizing reliance on fossil fuels.
• Reduced CO2 emissions percentage: Eramet claims a substantial reduction in CO2 emissions compared to traditional blast furnace methods. Specific figures will be available as the technology is further developed and deployed.

This innovative approach leverages the power of renewable energy and hydrogen to create a significantly more sustainable steel production process.

Advantages of eraLow over Traditional Steelmaking

Eramet's eraLow offers several key advantages over traditional steelmaking:

• Lower carbon footprint: Significantly reduced CO2 emissions, contributing to climate change mitigation.
• Reduced reliance on fossil fuels: Minimizes dependence on coal and other fossil fuels, enhancing energy security.
• Potential for cost reduction in the long term: While initial investment is high, the long-term cost of production could be lower due to reduced energy and raw material costs.
• Improved product quality (if applicable): The process may offer opportunities to improve the quality and properties of the resulting steel.
• Scalability and potential for large-scale implementation: The eraLow process is designed for scalability, potentially enabling widespread adoption in the future.

Compared to other low-carbon steel production methods, such as electric arc furnaces (EAFs) that utilize scrap steel, eraLow offers the potential for a more significant reduction in emissions by creating green steel directly from iron ore.

The Future of Low-Carbon Steel and Eramet's Role

The future of the steel industry hinges on the successful adoption of low-carbon steel production technologies. The market for sustainable steel is rapidly expanding across various sectors.

Market Opportunities for Low-Carbon Steel

The demand for green steel is surging in numerous sectors:

• Automotive: Automakers are increasingly incorporating sustainable steel in their vehicles to meet stricter environmental regulations and consumer demand.
• Construction: The construction industry is seeking to reduce the carbon footprint of buildings by using low-carbon steel in construction materials.
• Energy: The renewable energy sector, particularly in wind turbine manufacturing, requires substantial amounts of high-quality steel, driving demand for sustainable solutions.
• Infrastructure: The development of sustainable infrastructure projects is fostering demand for environmentally friendly steel.
• Packaging: The packaging industry is also exploring the use of sustainable steel alternatives to reduce its environmental impact.

Challenges and Future Developments in Low-Carbon Steel Production

Despite the potential benefits, several challenges need to be addressed:

• High initial investment costs: The transition to low-carbon steel production requires significant upfront investments in new technology and infrastructure.
• Need for renewable energy infrastructure: Widespread adoption of hydrogen-based steelmaking requires a robust renewable energy infrastructure to power the electrolysis process.
• Technological advancements required: Further technological improvements are needed to optimize the efficiency and cost-effectiveness of the eraLow process.
• Supply chain integration: Effective integration of the eraLow process into existing steel supply chains will require careful planning and coordination.

Eramet is actively working to overcome these challenges through continued research and development, strategic partnerships, and investments in renewable energy infrastructure.
