The iron and steel sector is key to the global economy but is a big source of greenhouse gas emissions. It’s responsible for about 7-9% of global emissions. To make steel production more sustainable, carbon capture technology is being explored.
This technology, including CCS and CCUS, aims to cut down emissions. Yet, CCUS only captures 0.1% of emissions globally. As we look into carbon capture in steel making, we see a big need for change and challenges to overcome.
The Role of Carbon Capture Technology in the Steel Industry
Decarbonization is key to fighting climate change, and the steel industry is a big part of it. It’s responsible for a lot of greenhouse gas emissions. Now, people want the steel industry to be more green. This has made carbon capture technology very important.
The steel industry needs to find ways to make cleaner steel. This has led to more interest in carbon capture technology. It’s pushing the industry to use new and green methods.
The Importance of Decarbonization
Steel making creates about 3 gigatonnes of carbon dioxide every year. This is about 9% of all energy-related CO2 emissions. The Blast Furnace – Basic Oxygen Furnace (BF-BOF) process is a big part of this problem.
It’s important for the steel industry to cut down on CO2. This is key to meeting climate goals. Around the world, projects are looking into carbon capture technology.
Places like the UK, Norway, and the Netherlands are leading the way. They’re adding carbon capture to their industrial areas.
Current Carbon Capture Performance
Even though carbon capture technology is promising, it’s not doing great right now. Only about 0.1% of all emissions are captured. This is a big challenge.
Places like the Al Reyadah in Abu Dhabi show how hard it is. They can only capture 20-26% of emissions. This is much less than what was hoped for.
In 2022, 61 new carbon capture facilities started up. But, the market is growing slowly. The cost of capturing CO2 has gone down in some areas. This could make carbon capture more affordable for the steel industry in the future.
Challenges Facing Carbon Capture Technology for Iron and Steel Manufacturing
Using carbon capture technology in iron and steel making is tough. The industry wants to use less carbon, but faces many obstacles. It’s important to know these challenges to make carbon capture work well.
Technical and Financial Barriers
Setting up carbon capture systems is hard because of how steel plants are built. Each plant needs its own solution, making it hard and expensive. Also, using coal makes it even harder to switch to cleaner energy.
Big tests are needed to show if carbon capture works for steel. Making clean steel costs more than old ways. Without help from governments and other countries, it’s hard to keep going.
Low Capture Rates and Commercial Viability
Now, carbon capture systems catch only a little carbon. This means they don’t cut down on emissions much. Places like Al Reyadah haven’t done as well as hoped, making them seem not worth it.
The steel world needs better carbon capture tech. It needs money and effort to figure out how to make low-carbon steel cheaper. It’s key to make these systems catch carbon well and be affordable.
Future Perspectives on Carbon Capture Technology in Steel Production
The future of CCUS in steel production depends on tech innovation, regulatory support, and market changes. The industry is moving towards sustainable practices like hydrogen-based steelmaking. This could make traditional carbon capture methods less important.
Direct Reduced Iron (DRI) technology, using hydrogen, shows promise for better emission control. It could significantly cut CO2 emissions.
CCUS technology has captured only 0.1% of global emissions over 50 years. It faces big challenges, with many large projects failing to meet their goals. This makes investors question CCUS as a main way for steelmakers to cut emissions.
The steel sector is a big emitter, with 2.7 billion tons of CO2 each year. Finding new ways to cut emissions is urgent. This is why green steel production is getting more attention.
Green steel production faces high costs and the need for reliable energy for green hydrogen. But, it offers lower carbon emissions and energy use. With steel demand set to rise by 35% by 2050, investing in green tech is key for the industry’s future.
