GeoPolyHeat Oy
Finnish engineering company pioneering thermal energy storage for decarbonized industry.
Our Journey
The Invention
GeoPolyRage was born from a fundamental question: what if industrial waste heat didn't have to be wasted? GeoPolyHeat Oy's engineers developed a geopolymer-based thermal storage medium capable of storing heat at unprecedented densities.
From Lab to Industry
Years of materials science R&D translated into a modular, scalable system architecture. TESS was designed from day one for real industrial environments — not lab conditions.
Global Expansion
GeoPolyRage is now available for international deployment. GeoPolyHeat Oy partners with distributors, engineering firms, and energy integrators worldwide to deliver TESS solutions.

"Finnish high‑temperature TESS innovator targets Europe's industrial resilience market"
As Europe accelerates the decentralization and hardening of its critical energy infrastructure, GeoPolyHeat Oy's GeoPolyRage® high‑temperature Thermal Energy Storage System (TESS) is emerging as a key technology for industrial‑scale thermal autonomy and microgrid resilience.
Unlike conventional water‑based storage solutions, GeoPolyRage® utilizes an ultra‑stable geopolymer thermal mass capable of operating safely far beyond the limits of traditional materials. This enables factories, process‑industry sites and off‑grid production facilities to secure high‑temperature heat without dependence on volatile fuel supply chains or centralized heat networks.
Industry analysts note that the technology's modular design, high durability and minimal maintenance requirements position it uniquely for the rapidly evolving European market, where industrial microgrids and behind‑the‑meter heat systems are becoming strategic priorities.
According to GeoPolyHeat Oy, GeoPolyRage® TESS provides a scalable pathway for companies seeking energy independence, lower operating expenses and improved climate resilience, especially in sectors where high‑temperature process heat is essential.
