After the successful development and operation of the 6 HAL4e test cells at its Årdal research Center starting in 2008, Hydro decided in 2015 to build an industrial pilot plant. The site chosen is on Karmøy island in Norway, on the very same, cleaned site where the Karmøy Søderberg plant once operated. The 60-cells plant is called the Karmøy Technology Pilot, or KTP for short.
The HAL4e cell development program’s ambition included step improvements in energy consumption and environmental friendliness. These innovations span many aspects of cell technology, environment protection, infrastructure and operation, like low cell resistivity, PAH-free linings, low energy cell preheat and start-up, low specific energy consumption, low anode effect rate and duration, low fluoride emissions, low CO2 emissions, automated cell operations and many more.
This paper summarizes the preparation and start-up activities and also presents operating results of the first two years of operation.
