The HyInHeat project, launched in 2023 with €24 million in EU funding, aims to decarbonize heat-intensive processes in the aluminium and steel industries by exploring hydrogen's potential. Speira, part of the project, successfully converted a 1.5-tonne melting furnace to operate on hydrogen, showcasing no quality compromise in the melted metal. Galyna Laptyeva, the Senior Scientist, expressed optimism about hydrogen's suitability as a fuel, marking a significant stride in reducing carbon intensity. Speira further improved efficiency by switching to oxyfuel combustion with pure oxygen, anticipating a 30% reduction in fuel consumption. While hydrogen combustion is generally low in harmful emissions, researchers are working to minimize any produced pollutants. This successful conversion highlights the company's commitment to low-emission processes and aims to offer sustainable production approaches for the industry at large.
