About

Nostromo Energy develops an ice-based energy storage system designed for commercial and industrial buildings. Its core product, the IceBrick®, stores energy in the form of ice during periods of low electricity prices or high renewable energy availability, and discharges it during peak demand to reduce grid reliance and energy costs. The system enables buildings to become energy storage assets, supporting decarbonization and grid stability. Modular, compact, and non-flammable, IceBrick® can be retrofitted to existing structures, offering a safe and sustainable alternative to conventional battery storage.
