A geothermal solution for land-based salmon farms

A Norwegian company is looking to develop deep geothermal energy projects in order to make land-based aquaculture facilities more sustainable.

According to Rock Energy, there are currently between 100 and 200 companies planning annual production of up to 2.3 million tonnes of salmon on land, of which about half is planned for Norway.

Should the projects succeed, it would almost double the current total marine production of salmon (​​about 2.7 million tonnes) and require large amounts of energy.

The solution being evaluated by Rock Energy means that energy can be produced locally and will reduce
the burden on both existing and new establishments of infrastructure for energy deliveries.

Land-based aquaculture sites are typically very energy intensive compared to traditional net pen systems

Rock Energy AS specialises in the utilisation of deep geothermal energy and says that it “possesses knowledge, patents, as well as geotechnology that make it possible to utilise geothermal energy in an efficient, industrial and sustainable way in the aquaculture industry, regardless of location and access to power grids and infrastructure along Norwegian fjords”.

"Our technology will be utilised for a new, holistic and unique energy concept. The solution is based on offering the aquaculture industry energy, in the form of heat and electric power production," said Lars Due, COO of Rock Energy, in a press release.

Rock Energy is evaluating the possibility of installing a number of facilities that are owned and operated through various single purpose vehicles (SPV) companies, through which players in the aquaculture industry will also have the opportunity to become co-owners. Each individual SPV will sell capacity and energy supply to the aquaculture industry.

Aquaculture is an increasingly important source of safe, nutritious, and sustainable seafood for people worldwide. Globally, aquaculture production must double by 2030 to keep pace with demand. These increases in demand for aquaculture products, food security considerations, and job creation have generated an increased need for skilled workers.
