Solutions for Every Industrial Context
From factory floors to military microgrids — GeoPolyRage TESS adapts to where energy resilience matters most.
Reliable thermal energy. Lower emissions. Higher performance.
- High-temperature storage without pressure vessels – more safety, less cost
- Modular design integrates seamlessly into any industrial environment
- Long service life and minimal maintenance due to the chemical and thermal stability of geopolymers
- Significantly lower CO₂ footprint compared to cement-based systems
GeoPolyRage® TESS revolutionizes industrial energy strategy
GeoPolyRage® TESS is not just a heat-storing material, but a strategic tool for optimizing energy efficiency and costs.
The exceptional thermal stability of the geopolymer-based heat storage ensures reliable operation at temperatures exceeding 500°C — confirmed in multiple independent studies. TES prototypes have demonstrated significantly better thermal capacity and high-temperature behavior compared to OPC-based systems.
According to our customers, GeoPolyRage® TESS has reduced operational costs, improved energy management transparency and enabled entirely new operating modes in production. When heat can be stored and released in a controlled manner without pressure vessels, the system is simplified and risks are reduced.
GeoPolyRage® TESS redefines industrial energy economics.
Modular GeoPolyRage® TESS integrates seamlessly into any industry
GeoPolyRage® TESS stands out in the market particularly for its modular structure, which enables rapid installation, flexible scaling and easy connectivity to existing processes.
The mechanical and thermal durability of the geopolymer-based storage has been demonstrated in laboratory studies: the material maintains its structural integrity at temperatures up to 800–900°C without sintering and without loss of strength.
Heat flow and thermal capacity between modules has been optimized in CFD-based simulations, ensuring accurate operation across different usage scenarios.
GeoPolyRage® TESS offers a clear path towards a modern, modular and sustainable energy system.
Collaboration with GeoPolyHeat Oy elevates industrial sustainability to a new level
Partnering with GeoPolyHeat Oy means more than acquiring a single energy solution — it is a step towards a sustainable and circular economy-based production model.
Geopolymer technology is based on the chemical activation of aluminosilicates, where the carbon footprint of the manufacturing process is according to studies up to 80% lower compared to traditional cement. Geopolymers maintain their thermal stability in repeated thermal cycles.
- Fewer emissions
- Less waste material
- Longer service life
- Lower energy loss
GeoPolyRage® TESS is the new benchmark for sustainability solutions.
GeoPolyRage® – Expertise from consulting to commissioning
From initial assessment to simulations and finally commissioning — every TESS unit is designed and sized based on the customer's critical thermal loads.
The thermal behavior of the geopolymer material has been validated in repeated high-temperature tests. Simulation models (CFD + thermal transients) are based on the latest research on geopolymer thermal capacity, diffusion and structural stability.
"GeoPolyRage delivers exactly what is promised – reliable, high-temperature thermal energy that improves our process performance and reduces costs."
GeoPolyRage® TESS combines engineering-level simulations, advances in materials science and practical industrial expertise.
Industrial Process Heat
Capture heat from furnaces, kilns, compressors, and exhaust streams. Feed it back into your process as usable steam, hot water, or air — slashing fuel consumption and CO₂ emissions.
Commercial & Facility Portfolios
Deploy TESS across industrial parks, logistics hubs, hospitals, and data centers. Centralize thermal management and achieve facility-wide energy self-sufficiency.
Renewable Integration
Convert excess solar or wind electricity into high-grade thermal energy. Store it in TESS and dispatch as process heat — the most cost-effective form of long-duration energy storage.
Decentralized Microgrids for a Resilient Europe
The war in Ukraine has made one thing clear: centralized energy infrastructure is a vulnerability. GeoPolyRage TESS enables fully autonomous thermal microgrids — designed to keep critical operations running when the main grid fails.
From defense facilities to hospitals and industrial hubs, our systems provide the thermal backbone of true energy independence. No fuel imports. No grid dependency. No compromise.
