An accumulator integrated into industrial processes. Commercial development builds on the Valleyfield installation.
Discover TESSAInvestors
A technology in operation. Two lines of development.
Tessart addresses a concrete need: supplying heat when it is needed, from energy that is not always available at the same moment.
The need
Heat is going electric. The grid has its busy hours.
Electrifying heat for processes and buildings adds electrical demand, often at the same hours.
Thermal storage makes it possible to charge at one time and deliver heat at another. It makes electrification easier to integrate, for the site and for the grid.
Operating proof
15 MWh in operation. In Valleyfield, since 2025.
The technology is in service. A TESSA installation is operated at an industrial site, under real conditions.

Two lines of development
Industrial and residential. Two markets, one principle.
Residential
StoQ Residential
The same principle, applied to home heating, alongside the heat pump.
Discover StoQNext steps
What we are working on. In qualitative terms.
-
Commercial development
Carry out more project analyses with industrial sites and their engineering firms.
-
New applications
Extend integration to other forms of heat delivery, at the pace of the projects assessed.
-
Residential line
Continue developing StoQ, in forced air and hydronic versions, through to validated technical data sheets.
These directions are qualitative. They are neither an offer of securities nor a promise of return.
