Making energy available when and where you need it.

EnergyNest’s Thermal Energy Storage is changing the energy storage game with a system of modular storage elements. This simplicity is what makes it surprisingly smart. EnergyNest Thermal Energy Storage is scalable, durable, and easy to install and operate.

The ThermalBattery stores heat energy from industrial sources (steam, thermal oil) in a unique solid-state storage medium: HEATCRETE®. This storage medium differs significantly from regular, structural concrete. HEATCRETE® has a higher thermal conductivity resulting in very effective heat transfer. At the same time, it is chemically stable at high temperatures (design for operation up to 450°C) and has high tensile strength to withstand repeated thermal stress cycling.

Windsor Energy is the exclusive representative for EnergyNest in Europe, Australia & New Zealand.

EnergyNest Modules are flexible and scalable

The unique modular design enables users to stack the modules like building blocks and scale the number of modules to fit the required storage capacity. EnergyNest is custom-made to fit your needs and can be scaled from a few MWh_th into the GWh_th range – simply by adding more modules. As such, it can be configured and adapted to a variety of storage applications and requirements.

Thanks to prefabricated piping and easy on-site assembly, EnergyNest already saves time and money in the installation phase. It is also suited for containerized logistics – each module has the same dimensions as that of a 20 ft container.
