Green steel refers to steel produced with significantly reduced carbon emissions compared to traditional methods, primarily by using renewable energy and alternative fuels like hydrogen. The process often involves replacing coal with green hydrogen in direct reduction of iron (DRI), and utilizing electric arc furnaces for melting. Carbon capture and storage (CCS) technologies can also play a role in further reducing emissions.
Key aspects of green steel production:
Renewable Energy:
Reliance on sources like wind, solar, and hydropower to power the entire process, including electrolysis for hydrogen production.
Green Hydrogen:
Utilizing hydrogen produced from renewable electricity and water to reduce iron ore in the direct reduction process. This replaces the use of coke or coal in traditional steelmaking, which produces carbon dioxide.
Scrap Steel Recycling:
Integrating recycled steel scrap into the production process, minimizing the need for new iron ore and reducing overall environmental impact.
Carbon Capture and Storage (CCS):
While not always the primary focus, CCS technologies can capture and store remaining carbon dioxide emissions from the process.
Electric Arc Furnaces (EAF):
Employing EAFs for melting, especially when using DRI, can further reduce emissions compared to blast furnaces.
Clean Technologies:
Utilizing efficient and cleaner technologies throughout the steelmaking process, such as optimized furnace designs and waste minimization strategies.
Digitalization and Optimization:
Leveraging sensors and data analysis to create a "digital orchestra" of interconnected processes for improved efficiency and sustainability.
Ammonia as a Reducing Agent:
Exploring the use of ammonia as a reducing agent in iron ore, producing nitrogen gas and water as byproducts.
Challenges and Considerations:
Cost:
Green steel production can be more expensive than traditional methods, particularly due to the cost of green hydrogen and renewable energy.
Infrastructure:
Transitioning to green steel requires significant investments in new infrastructure, including renewable energy sources and hydrogen production facilities.
Scalability:
Scaling up green steel production to meet global demand will require overcoming technological and logistical hurdles.
Carbon Intensity:
Some methods marketed as "green steel" may still have a degree of carbon intensity, especially if they rely on CCS or utilize blue hydrogen (hydrogen produced from fossil fuels with CCS).
Current Trends and Outlook:
Growing Market:
The global green steel market is experiencing significant growth, driven by increasing awareness of climate change and the need for sustainable solutions.
Regional Hubs:
Regions like Europe are emerging as leaders in green steel development and adoption, with countries like Sweden, Germany, and Finland taking a leading role.
Price Premiums:
There's a growing willingness from consumers and businesses to pay a premium for green steel, recognizing its environmental benefits.
Innovation and Research:
Continuous research and development efforts are focused on improving green steel technologies and reducing costs.
I recently spoke to a person from Crowsnest Pass, whose family has been involved in mining for decades. They could see the environmental side, but jobs, jobs, jobs were their priority. I tried to explain that the jobs won't last, and the profits are headed to Australia. It's a hard sell.
This is a worthy watch if only to hi-light the typical marketing hype for a nascent industry. Meanwhile, the steel makers with existing blast furnaces won't stop using them until they reach the end of their useful life - and will only replace them with 'green steel' if and when it matches the economics, particularly in developing nations.
It's also a lesson in how a guy gets rich on emissions then pivots to a 'clean industry' as his wish for a clean legacy.
Henriksson’s career has been built in industries with high emissions: trucks, appliances, defense, and steel. His recent pivot to “green” steel follows decades of leadership roles in carbon-intensive sectors. His influence and wealth stem from industries that rely heavily on fossil fuels.
The Smith government and responsibility don’t belong in the same sentence, follow the money.

Nice work if you can get it.
