Power consumption

Power consumption during the first fish generation in Ovum E2000 pilot ended up at 1,8 kwh/kg produced salmon.
This is about 1/3 compared to the best land-based salmon farms using RAS (Recirculating Aquaculture Systems).
The main reason for low power consumption is the low pumping height. We are not lifting any water, just moving water in water. The water intake design with minimum flow restrictions as well as efficient outflow pumps at the top of Egget® are also crucial.
The power consumption includes on-site oxygen production, which means reduced emissions from road transport of liquified oxygen.
The goal is set to 1 kWh/kg, which seems reasonable knowing that the current system has not yet been tested to its full capacity.
The power consumption pattern for Egget® has shown to been very stable. It has been 100% covered by shore power. Implementation of other renewable sources are evaluated for the future.
