| Abstract Scope |
Aluminum production emits ~270 Mt CO2/year and is a crucial material for the energy transition. Decarbonization of aluminum production is critical for the aluminum sector itself, but also for sectors such as automotive, building and construction and the energy sector. Hydro is working to qualify hydrogen as a fuel for aluminum melting furnaces, using a systematic and risk-based technology qualification framework. The qualification activities reduce risk and increase confidence related to its suitability. In June 2023, Norsk Hydro, and Fives North American Combustion performed a series of tests in Hydro’s casthouse in Navarra, Spain. Using hydrogen to melt ~200 tons of aluminum, Hydro and Fives has developed a significant scientific basis for further development in this area. The tests focused on safety performance, metal quality, energy efficiency, production capacity, emissions, and operational effects. The technology readiness level of hydrogen used as fuel in aluminum melting furnaces is defined as 7. |
