Patented proprietary technology

Eco-Stock® — High-temperature thermal storage

The Eco-Stock® transforms a variable and intermittent heat source into a clean, on-demand, power-controlled heat supply. It captures heat, stores it in ceramic blocks, then delivers it.

Up to 1,500 °C Stored temperature
1 to 30 MWh Capacity per installation
> 90 % Efficiency

Eco-Stock® installation Tegulys
Ceramics · In service since 2019
Tegulys

Recovery of waste heat from the firing kiln to the dryer. Eco-Stock® 1.3 MWh at 600°C. Zero investment by the site (ADEME grant + leasing).

–20 %natural gas (660 MWh/year)
160 t CO₂avoided per year

"The Eco-Stock® solution improves the energy efficiency of the firing process and also increases our production capacity."

Nicolas Ducrot, CEO — Tegulys
Wienerberger Pontigny site
Ceramics · In service since 2024
Wienerberger

2 Eco-Stock® units on the Pontigny site to recover heat from 6 kilns to the dryers, replacing burners. Fixed heat contract for 10 years.

–15 %natural gas (2,400 MWh/year)
500 t CO₂avoided per year

"Eco-Tech Ceram will enable us to recover waste heat from the six kilns at the Pontigny site and save 480 tonnes of CO₂ per year."

Robert Lacroix, Director of Sustainable Development — Wienerberger France
Heat exchanger installed at Villeroy & Boch
Ceramics · In service since 2023
Villeroy & Boch

Electrification coupled with an Eco-Stock®: tunnel kiln waste heat recovery + electric E-Burner + high-temperature storage. 100% decarbonized drying.

–42 %natural gas (3,000 MWh/year)
1,000 t CO₂avoided per year

"The plant will thus reduce its gas consumption by 42% compared to 2021. Without these savings, the site would be threatened by rising gas prices."
