Cartesian

Cartesian is a pioneering company specializing in modular and cost-effective thermal energy storage systems. These systems are designed to optimize energy usage, balance grid capacity, and store surplus energy for later use, making them ideal for large heating and cooling systems. The company primarily serves energy-intensive sectors looking to boost energy efficiency and rapidly reduce their carbon footprint. Cartesian operates in the renewable energy market, leveraging over 10 years of research and development conducted at SINTEF, one of the largest independent research organizations. The business model revolves around providing scalable and flexible energy storage solutions based on phase change materials (PCM), which can adapt to a wide temperature range and have a minimum lifetime expectancy of 25 years. Cartesian generates revenue by selling these advanced energy storage systems to industries and commercial entities aiming for sustainable energy solutions. The company is a spin-out from SINTEF Energy Research and is owned by its four founders and SINTEF Venture. Cartesian's technology has been validated through various research and demo projects, including successful pilots at the Zero Emission Building in Trondheim and a CO2 cooling system in a supermarket. More pilot projects are in the pipeline to demonstrate diverse use cases.
