The first modular water-based energy storage cell

Nostromo Energy’s IceBrick is a behind-the-meter energy storage solution that harnesses water’s extraordinary ability to store energy when changing phase to ice. It creates ice during off-peak hours and uses these capsules to cool the building’s circulated water at peak hours. This dramatically lowers energy consumption from HVAC usage, which accounts for 40% of peak electricity demand.

Unlike most energy storage solutions, it is compact and modular, able to be fitted into any building’s space constraints. By designing it to utilize water as its main energy medium, Nostromo Energy indicates that the IceBrick is completely safe to use and eco-friendly.
