Hatch to bring in CRISP+ for use in green steel production in Tata Steel’s factory in Netherlands, moving further towards DRI technology.
Here’s an article posted in Hydrogen Central that talks about Tata Steel’s zero-carbon production.
According to the article,
- Tata Steel aims to produce steel with zero carbon emissions by 2045
- Hatch will provide engineering for the reducing electric furnace (REF) package
- The hydrogen route project will employ Hatch’s CRISP+ furnace technology
- Tata Steel will convert its steelmaking facilities from coal-based to hydrogen-based
- The project will cost in excess of 65 million euros
CRISP+, which stands for Continuous Reduced Iron Steelmaking Process Plus, is a novel technology for steel production aimed at reducing emissions and improving efficiency. Here’s a breakdown of what we know:
Core Technology:
Our specialty focus areas include 
- Continuous Process: Unlike conventional Electric Arc Furnaces (EAFs) functioning in batches, CRISP+ enables uninterrupted steel melting and refining, potentially boosting production and reducing costs.
- Stationary Electric Furnace: CRISP+ uses a stationary electric arc furnace, differing from traditional EAFs that have a tilting mechanism.
- Focus on DRI (Direct Reduced Iron): The process is designed to efficiently handle DRI, a semi-finished steel product with a lower carbon footprint compared to iron ore.
Benefits of CRISP+ (as claimed):
- Reduced Emissions: Compared to traditional EAFs, CRISP+ promises lower CO2 emissions due to its focus on DRI and potentially cleaner electricity sources.
- Increased Efficiency: The continuous operation and improved refractory life (lining of the furnace) can lead to higher production capacity and potentially lower energy consumption.
- Yield Improvement: The technology claims to offer better control over the steelmaking process, potentially resulting in a higher yield of usable steel.
Limitations and Unknowns:
There isn’t a wealth of publicly available information about CRISP+. Here are some aspects that would be helpful to know:
- Technical Details: Specific details about the furnace design, operation parameters, and how it achieves the claimed benefits are not readily available.
- Commercialization Stage: It’s unclear how widely adopted CRISP+ technology is. While Hatch seems to be involved in projects like the one with Tata Steel, more information on existing implementations would be valuable.
- Comparison with Alternatives: Understanding how CRISP+ stacks up against other green steelmaking technologies like hydrogen reduction would be informative
