GreenBlu is developing a Vapor Adsorbed Distillation system with Energy Recycling (VADER) to provide zero carbon, zero liquid desalination and water purification that is powered by either solar or waste heat from variable input sources.

Even as California experienced the worst drought in centuries, 40 water experts gathered at Woods Institute for the Environment at Stanford in January of 2016, and reached the consensus that desalination is unlikely to ever contribute significantly to California’s water supply, largely due to cost, electrical energy intensity, and environmental impact. This result illustrates that current desalination techniques are still too painful to widely deploy.

GreenBlu was founded in 2016 based on this idea: rising demand for clean water simply can`t be met by current desalination and treatment methods, and that new technologies are needed.

Our patented distillation method recycles the heat of adsorption, the latent heat of vaporization, and the sensible heat multiple times. This new distillation method is enabled by our patented high thermal-conductivity nanocomposite adsorbent. GreenBlu’s distiller can triple the efficiency of current thermal distillers (MSF/MED). Our adsorbent acts as a water vapor pump, adsorbing and desorbing pure vapor without contacting the input water, making the adsorbent permanent. Distilled water is a high purity product that can be easily customized for all uses, industrial, agricultural, and potable. Our techniques requires less pretreatment and testing than reverse osmosis and uses 30-80 times less electricity when desalinating seawater. Our desiccation process can dry input liquids, regardless of concentration,into solids. When applied to the rapidly growing zero liquid discharge applications. Applying our zero-carbon method to seawater reverse osmosis brine waste would enable the mining of magnesium and salt from seawater, cost-effectively and renewably producing the lightest structural metal for improving transportation efficiency.
