Constellium announces industrial testing of hydrogen use in casthouses

Constellium announced its move towards industrial testing of hydrogen utilization in its casthouses, marking a significant step in its commitment to decarbonizing its operations. Recycling and casting are the most energy intensive operations and represent close to 50% of Constellium’s direct greenhouse gas emissions. Building upon successful laboratory-scale trials conducted in 2022 by C-TEC, Constellium’s main R&D center, the Company was able to demonstrate that transitioning from natural gas to hydrogen has no adverse effects on energy efficiency, oxidation rate, or product quality, with a focus on ensuring safe operations. This first demonstration phase has paved the way for industrial-scale testing at C-TEC. In preparation of the industrial testing phase, C-TEC has equipped one of its furnaces with a highly efficient burner capable of operating with oxygen and both natural gas and/or hydrogen. First results are expected Q3 2024.
