Green Mountain and Hima Seafood have marked the launch of their joint excess‑heat reuse project in Rjukan, Norway. The initiative represents an innovative industrial collaboration that combines sustainable data center operations with land‑based trout farming.
In this project, Hima Seafood will use excess heat from Green Mountain’s data center to warm the water in its aquaculture systems. After use, the cooled water can be returned to Green Mountain and integrated into its cooling processes. This closed‑loop energy system reduces energy consumption and environmental impact for both companies, offering a practical demonstration of circular economy principles in action.
Construction and installation work have been completed, and the system went operational in autumn 2025. In the current phase, the heat‑reuse system is being tested with a capacity of up to 1.75 MW while the parties conduct a joint feasibility study to build operating experience. Insights from this first phase will guide phase two, which aims to scale the system to 8 MW.
