Norway's Thermal Box Technology Aims to Replace Nuclear Power in Europe
The Thermal Box, developed by Cartesian Energy, could allow for significant energy savings across Europe, avoiding the need for nuclear power plants. By installing Thermal Boxes in just four percent of commercial buildings, Europe could achieve energy generation equivalent to that of seven nuclear reactors.

The Thermal Box technology from Norway’s Cartesian Energy enables energy storage from renewable sources, potentially allowing Europe to avoid constructing seven nuclear power plants. Amazon has ordered thirty units to enhance cooling capacity at its warehouses in England, increasing efficiency by 38% without additional electricity consumption, with a return on investment in five years.
The design utilizes a patented ultrasonic sensor system for monitoring energy levels, a breakthrough after ten years of development at SINTEF. The Thermal Box is compatible with over 180 phase change materials and can be integrated into both new and existing buildings. If adopted widely, it could fundamentally alter energy consumption patterns in commercial sectors across Europe.
