The need

Given the unpredictability of renewable energy producers, such as sun and wind, grid owners are looking for cost-effective means of storing electricity. This is essential to solve issues such as instability and potential overload of the electricity grid.

The solution

Elestor electricity storage systems are based on hydrogen-X flow battery technology. Originally developed by NASA, Elestor has further engineered the concept to enable its use in a wide variety of grid and industrial applications. The active materials are low-priced as they are abundantly available on a global scale. The technology enables a high power density and high energy density, contributing to the reduction of storage costs.

The value proposition

  • Fast reaction kinetics, resulting in very short response times.
  • High accessibility, enabling easy maintenance and updates.
  • Independent configuration of storage power (MW) and capacity (mWh).
  • Modulary scalable, up to 10s of MW and 100s of MWh.
  • No self-discharge when system is idle.
  • Storage costs per MWh 5-10 times lower than incumbent systems.
