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.

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

1 — Capture

Heat from your processes (waste heat) or produced from electricity (hybridization) is directed to the Eco-Stock®.

2

2 — Store

It is stored in high-temperature ceramic blocks, which retain energy with an efficiency above 90%.

3

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.
