Cartesian
What we do:
We reduce operational costs, investments and CO2 emissions for heating or cooling systems.
We optimize energy efficiency.
We reduce grid constraints.
How:
By providing compact, safe by design, retrofit-ready thermal energy storage. Our solution is called Thermal Box.
Based in Trondheim, Norway, our technology is designed to meet the various demands of commercial buildings and district heating and cooling systems.
With partners and suppliers across Europe, we are committed to quality and integrity in everything we do, helping our clients build smarter, safer, and more sustainable energy solutions.
Our promise is precision, reliability, and efficiency at every stage.
The backstory
Our technology was developed by two of Cartesian’s founders through more than a decade of research at SINTEF, one of Europe’s largest independent research institutes. The uniqueness of the Thermal Box is its use of phase change materials (PCM), capable of efficiently storing heat or cold in a wide range of temperatures, with minimal losses.
Today, Cartesian delivers thermal energy storage that makes commercial buildings and district heating systems more energy efficient and sustainable.
What sets our solution apart is its ability to integrate seamlessly with existing heating or cooling systems.
Our goal is to make it easy for businesses to reduce energy consumption and operational costs, while contributing to a greener future. Our technology represents a step toward energy efficiency by offering a practical way to address today’s climate challenges.
Cartesian is especially setting a new standard for the optimisation of energy storage in commercial buildings. Our aim is to help create a future in which sustainability and efficiency go hand-in-hand with energy solutions that can play a crucial role in reducing the global carbon footprint.

Our services
At Cartesian, we deliver energy solutions that increase your energy capacity, efficiency and resilience. Our technology helps reduce energy consumption and relieves the pressure on HVAC systems by using stored energy more intelligently. Our modular, compact Thermal Box integrates easily, and the installation is quick, plug-and-play.
Thermal Box can be retrofitted into existing buildings and district heating and cooling systems, or easily specified into new projects, both large and small scale.
