WaHa is an early-stage company whose metal-organic framework (MOF) based dehumidifiers atmospheric water generators (AWG) efficiently remove humidity without subcooling the air and create pure water. This dramatically increases HVAC efficiency and reduces opex by 25-90% and HVAC capex by up-to 80%. The initial market is CEA but will scale to the overall HVAC market. This would reduce global HVAC electricity demand by 2%, or 1,900,000 GWh ($250B savings) and global GHG emissions by > 1 gigaton annually. Our AWG systems deliver a reliable quantity of pure, safe drinking water for the lowest energy cost, anywhere in the world, any time of year, under any atmospheric conditions.
