Overview
ISO/TR 25088:2026 – Guidance for the application of low-carbon technologies in steel plants is an internationally recognized technical report developed by ISO to support the iron and steel industry in achieving lower carbon emissions. This comprehensive document outlines a classification framework and provides detailed guidance on the application of a wide range of low-carbon technologies across the full spectrum of steelmaking processes. These processes include sintering, pelletizing, coking, ironmaking, steelmaking, continuous casting, rolling, and other associated production stages.
The aim of ISO/TR 25088:2026 is to provide the iron and steel sector with up-to-date, practical information on the selection, implementation, and integration of low-carbon technologies in diverse production environments. Recognizing the evolving nature of decarbonization pathways, this standard addresses both mature and emerging low-carbon solutions, acknowledging the diversity of technical and economic situations in steel enterprises worldwide.
Key Topics
-
Technology Classification: The standard groups low-carbon technologies into four primary categories:
- Smelting process breakthroughs
- Process optimization and innovation
- Resource recycling
- Carbon dioxide (CO₂) capture and utilization (CCU)
-
Smelting Process Breakthroughs: Encourages transformative innovations that move beyond traditional blast furnace methods. Emphasizes hydrogen-rich and direct reduction ironmaking, as well as advancements in electric arc furnace technology powered by low-carbon electricity.
-
Process Optimization and Innovation: Focuses on improving existing processes through energy efficiency, raw material composition, equipment upgrades, and maximizing renewable energy integration. Examples include near net shape rolling and thermo-mechanical processing.
-
Resource Recycling: Addresses technological approaches for the efficient reuse of solid, liquid, and gaseous by-products, promoting circular economy practices. Technologies include high scrap ratio smelting, slag reuse, and heat recovery.
-
CO₂ Capture and Utilization: Explores techniques to capture and repurpose CO₂ emissions, such as CO₂ mineralization, injection into basic oxygen furnaces, and chemical co-production strategies to create value-added products.
Applications
ISO/TR 25088:2026 is highly relevant for all stakeholders in the steel industry looking to accelerate their decarbonization efforts and meet global climate change targets. Key applications include:
- Steel Plant Operators: Provides clear guidance on integrating low-carbon technologies into new or existing production lines, from initial assessment to practical implementation.
- Project Managers and Engineers: Supports technology selection and project planning by classifying technologies according to maturity, technical feasibility, and applicability.
- Policy Makers and Regulators: Offers a neutral, authoritative reference for establishing or assessing compliance frameworks and incentives for low-carbon development in heavy industry.
- Supply Chain Partners: Helps suppliers of equipment and raw materials align offerings with industry needs and emerging best practices for sustainable metal production.
- Research and Academia: Serves as a basis for further innovation, pilot studies, and industry collaboration on low-carbon process improvements.
