Our technology — High-temperature thermal storage
Eco-Stock®: store heat, release it when you need it.
Our patented thermal storage system captures heat, stores it in ceramic blocks up to 1,500 °C, then delivers it on demand.
The problem
Available heat and the heat you need do not always coincide.
Some of your processes intermittently reject heat while others need heat at different times. Without buffer capacity, a large portion of this energy is simply lost.
Heat demand does not necessarily coincide with the hours when electricity is cheap. Without buffer capacity, much of the clean heat is not competitive.
The Eco-Stock® decouples the time when heat is produced from when it is consumed — giving your processes flexibility and stability.

Technical specifications
Storage designed for industry.
What you gain
What storage actually changes.
Heat delivered on demand
The captured heat is delivered at the right time and at the right temperature, even when the timing of your heat sources and heat demand are not synchronized.
Controlled high temperature
Up to 1,500 °C: the Eco-Stock® covers thermal needs that conventional storage solutions cannot address, for the most demanding industrial processes.
The lever to control your costs
Store during off-peak hours, discharge during peak hours: storage is what makes hybridization profitable and waste heat recovery flexible.
A lean and sustainable technology
Ceramic material storage, with no rare metals. A lifespan aligned with your industrial equipment (15 to 20 years).
How it works
Capture, store, release.
1 — Capture
Heat from your processes (waste heat) or produced from electricity (hybridization) is directed to the Eco-Stock®.
2 — Store
It is stored in high-temperature ceramic blocks, which retain energy with an efficiency above 90%.
3 — Release
On demand, heat is discharged at the desired power and temperature.
At the heart of our solutions
The Eco-Stock® integrates with your two decarbonization levers.
With waste heat recovery
Storage shifts and smooths the delivery of recovered heat to supply your processes at the right time.
With process hybridization
Storage enables the delivery of electric heat accumulated during the cheapest hours — the key to electrification profitability.
