NAPOP ventures into hydrogen production and fish farming

March 18, 2024  By RAStech staff

Norwegian green hydrogen company NAPOP is starting a venture that integrates hydrogen production with fish farming after securing aquaculture permits to produce up to 6,000 tons of fish annually.

Situated in Rendalen, Norway, the VIRIDIH2-PISCI model facility will incorporate a recirculating aquaculture system (RAS) constructed on land, with a 6 MW hydrogen electrolysis plant.

In its Norwegian press release, it states that VIRIDIH2-PISCI is NAPOP’s concept for sustainable electrolytic hydrogen production where all value streams from electrolysis find their allocation. 


“In VIRIDIH2, electrolysis is utilized to deliver hydrogen and oxygen with extreme purity. The oxygen is used directly as a resource in aquaculture along with the heat generated from the electrolyzer. Similar to hydrogen production, all product streams are also utilized in the aquaculture facility, including residual products from the water phase.”

The facilities are constructed with smart energy connectivity, making them available as resources for the power distribution system. The concept is patent pending.

“At NAPOP, we view VIRIDIH2-PISCI as a product based on a standard that can be established to suit various regions and locations. The first facility will be established in Rendalen (VIRIDIH2PISCI Mistra), where we currently hold the necessary aquaculture licenses. Subsequently, another facility will be located near the outlet of Krøderen. Land-based fish production requires capacities for temperature regulation as well as large quantities of oxygen,” said Terje Paulsen, NAPOP chief executive officer.

“The hydrogen will find its allocation, not least in our own technology used in NAPOP CTC heat centers as well as in our energy stations (NAPOP ES), which utilize hydrogen for the production of electrical energy,” Paulsen added.

“In a society where we increasingly witness the undesirable effects of past industrial practices across all sectors and areas, the need for holistic thinking regarding sustainable societal development resonates strongly with us. We must incorporate circularity into everything we do. This includes second-order resource management where the two solutions involve eliminating what we traditionally call waste as well as emissions. This is precisely the cornerstone of our strategy,” said Aage Bjørn Andersen, managing director of VIRIDIH2.
