Calor-e Oy is committed to transforming how the world produces, stores, and utilizes thermal energy. At the heart of our mission lies a simple yet powerful idea: heat can be clean, efficient, and renewable and it can be stored for when it matters most.

​

Operating in one of the most innovative and energy-conscious regions in the world, Calor-e Oy brings together advanced thermal energy storage (TES) technologies with the unique environmental and industrial needs of the Nordic countries. From harsh winters to high industrial heat demands, Finland requires smart, scalable energy systems and Calor-e Oy delivers just that. 

 

Our systems capture excess or low-cost energy such as wind or solar power and convert it into thermal energy, which is stored in high-efficiency materials and released precisely when needed. This enables factories, municipalities, and homes to reduce fossil fuel dependence, optimize energy use, and cut CO₂ emissions significantly. 

 

We blend Finnish engineering excellence with international R&D capabilities. We collaborate with local partners, utilities, and municipalities to create tailor-made solutions that align with Finland's ambitious climate targets and the EU's green energy transition goals. 

​
