Revolutionizing steel production: Demonstrating H2 heating solutions

In the realm of industrial processes, steel production stands as a cornerstone of modern infrastructure. However, traditional methods of steel production often come hand in hand with significant carbon emissions, contributing to environmental degradation. To combat this, the integration of hydrogen (H2) heating solutions presents a promising avenue towards sustainability. In this blog, we delve into the demonstration of H2 heating solutions in steel production processes, exploring its potential to revolutionize the industry.

The need for change

Steel production, vital for infrastructure and manufacturing, is notorious for its high carbon footprint. Conventional methods rely heavily on fossil fuels, such as coal and natural gas, for heating processes, leading to substantial greenhouse gas emissions. With increasing environmental concerns and stringent regulations, there is a pressing need for greener alternatives.

Demonstrating H2 heating solutions

Hydrogen, hailed as the clean energy carrier of the future, offers a compelling solution. Its combustion produces only water vapor as a byproduct, eliminating carbon emissions entirely when produced through renewable methods. This makes hydrogen an attractive candidate for decarbonizing industrial sectors like steel production. The demonstration of H2 heating solutions in steel production processes marks a pivotal step towards sustainable industrial practices. Several initiatives and projects worldwide are showcasing the feasibility and benefits of integrating hydrogen into steelmaking.


Demonstrators serve as testing grounds for H2 heating solutions. These facilities allow researchers and engineers to assess the viability of hydrogen-based technologies in real-world steel production settings. By experimenting with various process parameters and equipment, they refine the efficiency and effectiveness of H2 heating systems.

The different solutions studied at HyInHeat are applied in three real-world steel plants (2 in Spain and 1 in Norway) and two pilot plants (Spain and Sweden). All five plants represent different applications of hydrogen as a fuel in different processes in the context of the steel industry. In the case of the production plants, Ladle Furnace Preheater, Walking Beam Furnace and Tunnel Heating Furnace are considered. On the other hand, a Radiant Tube Furnace and a Walking Beam Furnace will be studied as pilot plants.

Technological innovations

Advancements in hydrogen production, storage, and utilization technologies play a crucial role in the adoption of H2 heating solutions. Innovations such as high-temperature electrolysis, hydrogen injection burners, and novel heat exchangers enhance the efficiency, reliability, and affordability of hydrogen-based heating systems. These technological breakthroughs drive down costs and overcome technical barriers, making H2 heating solutions more accessible to steel producers

HyInHeat is located in the consumption phase, in its combustion. Different burner solutions will be assessed, and will also address the challenge of how to modify a plant not originally designed to use hydrogen.

Another aspect to be taken into account will be the supply of hydrogen for testing. The different locations of the industrial plants will involve studying different sources and modalities of hydrogen supply, which will have to be applied for each situation, overcoming the challenges inherent to the situation of each plant.
