of Earth's water is accessible freshwater only.
Today’s desalination system is not sustainable for the future.
Massive saltwater disposal is causing environmental harm.
Environmental Degradation
R.O system generates brine as a byproduct, and the disposal of concentrated brine destroys our beautiful seas, such as coral, baby shrimps and fishes.
High Energy Consumption
R.O system has high energy requirements and produces tons of CO2, contributing to increased operational costs and environmental impact.
Reverse Electro Dialysis
RED is a type of Salinity Gradient Power (SGP) that does not produce any harmful matters to our environment and it achieves 100% clean energy.
Advanced Technology
RED is the leading salinity gradient technology, harvesting energy from seawater-freshwater salt differences.
High Energy Potential
SGP can generate a similar potential energy between seawater and freshwater to a 240-meter-high dam.
Global Estuary Potential
Estuaries around the world hold an estimated 30 TW of SGP, offering significant clean, emission-free renewable energy potential.
Growing Scale
As water use for energy production increases globally, SGP emerges as a substantial, environmentally friendly energy source.
Energy is derived from salt concentration differences in fluids, like fresh and salt water.
Integrating RED Tech
Minimal Energy Consumption
Over 30% reduction compared to standard R.O. processes. Among the lowest power consumption at 2.24 kWh/m3 for desalination.
No Brine Produced
The desalination process removes brine water, ensuring the discharged water retains the natural salinity of seawater without mixing.
Reduced CO2 Emissions
Potentially save 900,000 tons of carbon over 30 years, slashing emissions by over 0.5 kg CO2e/m3 compared to traditional methods.
