Hydro's Cell Technology Path Towards Specific Energy Consumption Below 12 KWH/KG
Published 2016 · Engineering
Hydro’s HAL Ultra cell technology development has achieved a major milestone to demonstrate greener aluminium production by operating two different electrolysis cell platforms at energy consumption levels below 12 kWh/kg. Two cells based on HAL300 and HAL4e technology have been rebuild with newly developed solutions to reduce cell resistance, enhance heat conservation and further improve standard operational procedures. Applying Hydro’s portfolio of modelling tools, materials knowledge, process know-how and operational competence enabled the development team to design high performance cell components and methods to reduce process variability. These elements were pre-tested on several cells before merging into full demonstrators. The HAL4e and HAL4e Ultra cell technologies will be installed as part of the Karmoy technology pilot plant.
