Recovered heat is worth nothing if you can't hold onto it. CREN's storage stage banks low-grade waste heat as latent heat in a Novacab TESS thermal battery — charged when heat is abundant, discharged exactly when you need it.
Inside the TESS unit, a Synthetic Phase Change Material melts as it absorbs recovered heat — storing enormous energy in the phase change itself. When the plant needs power, the PCM releases that latent heat back out at a steady temperature. No combustion, no degradation cycles like chemical batteries, no waste.
TESS thermal batteries are built, shipped, and craned onto rooftops and plant floors across North America. They arrive as complete units and integrate with the Sidel recovery chain upstream and the ORC conversion stage downstream.
In the full system, heat is captured at up to 800°F from the flue gas path and from vapour condensation and cooling-tower plume condensation — then held until the grid, the process, or the turbine calls for it.
"The business benefits of climate action are clear. Companies that align their strategy with climate science — and quickly integrate low-carbon solutions — are best placed to thrive in a net-zero economy."
