As part of the 2030 Climate Target Plan, the European Union has set a target of reducing green-house gas emissions by 55% and becoming carbon neutral by 2050. The use of hydrogen will be the backbone of the steel industry's transformation towards carbon neutrality. In the long term, for the vast majority of the roadmaps communicated by the various steel producers, the technical solution will...
“Hydrogen Utilization in Iron and steelmaking Processes” project (called GREINS project) started in 2021 with the aim of further reducing CO2 emissions based on the knowledge gained from the COURSE50 project. The project is a multi-track technical development project such as hydrogen reduction technology using blast furnace, hydrogen direct reduction technology to reduce low-grade iron ore,...
The blast furnace (BF) is the most energy-efficient iron-making process but faces significant challenges in the carbon neutral (CN) movement. To address this, we’ve developed a groundbreaking concept of CN BF, called SimpLE (Smart iron-making process for Low Emissions).
In Step 1, SimpLE aims for a near-zero Coke Rate (CR) through smart charging, smart reduction, and smart combustion. The...
The SMART acronym stand for “SteelMaking with Alternative ReductanTs”. This project aims at using local waste-based non-recyclable resources in steelmaking, and to do it in such a way that their intrinsic chemical value is fully recovered, thereby reducing the need for conventional reductants (fossil coal) and enabling a substantial reduction of CO2 emissions.
The main technical options...
The sinter plant plays a key role in processing internal by-products and waste materials from various processes within the steelmaking industry. However, sinter making is energy intensive, with no 100% green alternative, leading to substantial CO2 emissions. As a results, the sinter plant is not utilized in future green scenarios. An alternative could be found in cold bonded briquetting: a...
Decarbonization is a key strategic objective for the steel industry. Despite the growing interest in DRP-EAF steelmaking, BF-BOF steelmaking is anticipated to remain dominant due to its efficiency, economic benefits, and constraints associated with DRP-EAF. Therefore, it is essential to focus on reducing CO2 emissions from blast furnaces. This paper provides a detailed techno-economic...
In the steelmaking, integral cycles will face important investments for decarbonization, that will hardly get paid in the short term due to market outlook (dumping, weak border barriers, high energy costs…). In this context, ESCH and I.Blu are cooperating in some BFs ensuring reliable and continuous injection of BLUAIR, a high quality Secondary Raw Material recycled from polyolefins feedstock...
