| Abstract Scope |
Aluminum production emits ~270Mt CO2/year and is considered a key enabling material for the energy transition. Decarbonization of aluminum production is therefore critical, not only for the aluminum sector, but also for sectors such as automotive, building and construction and the energy sector. Hydro is working to qualify hydrogen as fuel for aluminum casthouses, using a systematic and risk-based technology qualification framework. The qualification activities seek to reduce risk and increase confidence related to its suitability. In June 2023, Hydro performed a series of experimental tests in our extrusion casthouse in Navarra, Spain. By producing ~200 tons of aluminum extrusion billet using hydrogen as fuel, Hydro have developed a significant scientific basis for further development in this area. The work focus on implications on metal quality, energy efficiency, production capacity and casthouse operation. The technology readiness level of hydrogen as fuel in aluminum casthouses is defined as TRL7. |
