In a recent development, a hydrogen-powered furnace successfully melted aluminium scrap, demonstrating high-quality melted metal. The tests were part of the EU-funded HyInHeat project, which focuses on sustainable heat technologies for the aluminium industry. Speira, a key player in the project, highlighted the benefits of using hydrogen for combustion in furnaces to reduce carbon intensity and improve efficiency. By transitioning from using normal air to burning hydrogen with pure oxygen, also known as 'oxyfuel,' efficiency is further increased. This shift not only enhances environmental friendliness but also brings about economic savings. While hydrogen combustion typically produces minimal harmful emissions like nitrogen oxides (NOx), researchers are working to minimize these through upcoming tests. Dr. Paula Camean Queijo from Speira emphasized how hydrogen usage is contributing to a more environmentally friendly production process. With the HyInHeat project running until 2026, the aluminium industry is set to pioneer a more sustainable approach, positioning Germany as an innovation hub in the sector.
