Steel Decarbonization: Challenges and Opportunities
The Steel Industry’s Carbon Footprint
You may not realize it, but the steel industry is one of the largest contributors to global carbon emissions. It accounts for 11% of global carbon emissions and 7-9% of greenhouse gas emissions. The primary culprit is the blast furnace-basic oxygen furnace (BF-BOF) route, which produces 86% of steel emissions. Even the electric arc furnace (EAF) route, often considered cleaner, contributes 15%. Additionally, mining metallurgical coal, a key input in steelmaking, can increase the carbon footprint by up to 27%.
The industry faces significant challenges in reducing its emissions. Here’s a breakdown:
| Challenge | Description |
|---|---|
| Reliance on carbon-intensive methods | The steel industry primarily uses blast furnace production, which is highly carbon-intensive. |
| High costs of new technologies | Implementing low-carbon technologies is expensive, creating a barrier to transition. |
| Investment needs | Significant investment is required to develop and scale low-carbon alternatives. |
These challenges make steel decarbonization a complex but urgent task.
The Role of Hydrogen in Decarbonization
Hydrogen offers a promising path to reduce emissions in steel production. Unlike traditional methods, hydrogen-based steelmaking replaces carbon with hydrogen as a reducing agent, eliminating CO2 emissions. For example, the HYBRIT project in Sweden has successfully produced fossil-free steel using hydrogen-based direct reduction. This innovation could bring fossil-free steel to the market by 2026.
Other opportunities also exist for the industry to adopt greener technologies:
- Assess and adopt clean technologies.
- Increase production of sustainable steel.
- Improve ESG (Environmental, Social, and Governance) performance.
- Embrace digitization to unlock value.
- Collaborate with stakeholders to accelerate the transition.
Hydrogen, however, is not without its challenges. Producing hydrogen efficiently remains a hurdle. Electrolytic hydrogen, for instance, has a round-trip efficiency of only 24%, leading to significant energy losses. Despite these limitations, hydrogen remains a key player in the journey toward steel decarbonization.
Thyssenkrupp’s Hydrogen-Based Steelmaking
Achievements in Hydrogen Steel Production
Thyssenkrupp has made remarkable progress in hydrogen-based steelmaking. On November 11, 2019, it became the first company to inject hydrogen into a blast furnace. This milestone demonstrated the potential to reduce CO2 emissions by up to 20% using hydrogen in traditional steel production. Thyssenkrupp also launched the tkH2Steel decarbonization project, which aims to revolutionize steelmaking.
The company introduced bluemint® Steel, a product that reduces CO2 emissions by up to 70% compared to conventional steel. This innovation represents a significant step toward sustainable steel production. Thyssenkrupp plans to operate a direct reduction plant fully on hydrogen by 2029. The plant will have the capacity to produce 2.5 million metric tons of directly reduced iron annually, saving up to 3.5 million metric tons of CO2 each year.
Thyssenkrupp employs advanced technologies to achieve these goals. Water electrolysis plays a key role in producing green hydrogen, which powers their hydrogen steel production. The company is also developing a direct reduction process that uses hydrogen instead of carbon, marking a major advancement in steel decarbonization.
Limitations and Challenges
Despite its achievements, Thyssenkrupp faces significant challenges. The high cost of hydrogen production and renewable electricity makes hydrogen steelmaking less economically viable than traditional methods. The company also requires large-scale renewable electricity production to support its operations. This dependency on intermittent renewable energy adds complexity to infrastructure planning.
Economic barriers further hinder the adoption of hydrogen-based technologies. Thyssenkrupp’s direct reduction plant project, supported by two billion euros in funding, highlights the financial resources needed to transition away from natural gas. The company must overcome these hurdles to make hydrogen steelmaking a widespread reality.
Thyssenkrupp’s efforts in hydrogen steel production showcase its commitment to innovation. However, addressing these challenges will be crucial for the company to lead the global transition toward sustainable steelmaking.
Baosteel’s Hydrogen Gambit
Strategic Vision for Hydrogen Integration
Baosteel has set ambitious goals to integrate hydrogen into its steel production processes. The company aims to boost the hydrogen ratio in its direct reduced iron (DRI) plant to 80%-90% by 2030. This shift will significantly reduce carbon emissions and align with global sustainability goals. By 2027, Baosteel plans to cut its carbon emissions by 30% compared to 2020 levels. The ultimate vision is to produce carbon-free auto sheet steel by 2030.
Baosteel has already taken a major step by initiating China’s first hydrogen-based shaft furnace. This facility, which began construction in February 2022, can produce one million tons of steel annually. By integrating hydrogen and coke oven gas, it aims to reduce CO2 emissions by 500,000 tons each year.
