DuraStor®

Containerised, Fast-power Storage Solution

Our DuraStor system is designed for fast power storage needs. It is a containerised solution which can fit to any business’ specific power and energy demands.

DuraStor offers a turnkey system with many benefits:

  • Largely independent from local and climatic conditions
  • Contained, fully integrated system
  • Fully self-reliant operation
  • Smoothly integrates into existing low voltage (LV) power grid landscape without any required complex control interface
  • Allows full transparent energy management system (EMS) or supervisory control and data acquisition (SCADA) integration when required
  • Optional concrete basement, for safe system installation and operation
  • Fully factory-tested product
DuraStor®

From Kilowatt to Megawatt

DuraStor solutions are based on the maintenance-free EnWheel flywheel. The modular concept can be customised and modified in both power and storage capacity to meet a variety of application needs. This offers maximum flexibility to fit any type of business case.

The Benefits of DuraStor®

Fully flexible and tailored to any needs, the DuraStor system offers many advantages for fast power storage:

  • Built for continuous high-power and cycling applications
  • Operates with zero emissions and no environmental risk – the system is completely free from any chemical additives
  • Connects to a low voltage connection point to absorb or deliver electrical power, with no need for further power connection or auxiliary supply
  • Is fully self-reliant for autonomous operation in case of external power failure, and manages power failure situations with ease
  • Controls local power flow using additional external sensors applied to the critical distribution or power connection points
  • Provides a fully integrated solution, complete with management and monitoring system, application interface and remote control

For further insight into how the DuraStor system can be implemented, please see our Flywheels for Microgrids whitepaper.
