Fully electric fish farm
The aquaculture industry currently produces approximately half of the fish for global consumption, and this is expected to reach two-thirds by 2030.[1,2] Given the trends in fish farming, one can anticipate bigger farm facilities that will be located further out to sea. This makes it increasingly infeasible to connect them to onshore electric grids.[3,4]
A typical salmon farm uses about 342 kWh/day and emits 120,000 kg of CO2 per year.[3,4] Common practice sees offshore fish farms being powered by diesel generators, but recent installations are starting to integrate hybrid power systems that incorporate renewable energy.
Hybrid systems can reduce costs by 16% and emissions by 50%. Fully electric fish farms, powered by wave energy, might not only produce sufficient energy to power their operations, but even excess energy to power the electric vessels that make the voyage to maintain, stock, and extract fish from the farm.[4,5]
When will a fully-electric fish farm, powered by wave energy and capable of charging service vessels, be installed on the sea?
