Powater
Our Power-to-water Battery stores surplus renewable energy and uses the stored energy for atmospheric water harvesting (AWH) or dehumidification.
The energy storage costs are 90% lower than using the traditional electrochemical energy storage systems. Approximately one kilogram of moisture is collected per kWh of electricity produced/dehumidified, with an efficiency of 80%.
