The revolutionary EnergyNest Thermal Battery system can deliver 4 combined or independent energy streams with >90% round trip energy efficiency utilising solid state heat exchanger tubes located in the thermal energy battery system.

The EnergyNest technology is applicable to multiple areas in energy and power grid systems. It is based on, and designed around, standard turbomachinery, so it can be easily combined with standard equipment.

The EnergyNest Thermal Batteries can be charged with electricity and/or be heated directly by industrial or solar sources.

The system is simple, robust, and comprises field-proven equipment:

Electric oil heater (or heat recovery oil heater, or concentrated solar power).

Steam island – consisting of:
– Steam generator.
– Steam turbine.
– Option for steam extraction.
– Condenser with district heating supply.
– Absorption chiller.

EnergyNest Modules are flexible and scaleable

Durable components combined with clever engineering result in a highly robust, flexible system that is easy to assemble.

Since the two main materials – concrete and steel – are broadly available and fully recyclable, the technology can be deployed in any geographical area and location.

Our unique modular design enables a “LEGO-like” feature: The number of modules stacked inside the steel structure like building blocks is determined by the required storage capacity and duration.

EnergyNest is custom-made to fit your needs and can be scaled from a few MWhth into the GWh range – simply by adding more modules. As such, it can be configured and adapted to a variety of storage applications and requirements.

Thanks to pre-fabricated piping and easy on-site assembly, EnergyNest already saves time and energy in the installation phase. It is also suited for containerized logistics – one module fits into a standard 40-foot container – making multi-module shipping easy.
