Think Water

True nature inspired








Make Water

With precise engineering








Use Water

In a sustainable way








What we do


  • Our desalination technology replicates the natural water cycle: evaporation of seawater (humidification) and the subsequent condensation of the generated steam (dehumidification).
  • The steam is completely clear and does not contain any salt.
  • During condensation, the main portion of the energy used for evaporation is harnessed through a highly efficient heat exchanger.

Sustainable Development Goals Compatible


Mission statement

  • Harness renewable energy to deliver high quality purified water worldwide.
  • Produce purified water in water-scarce or constrained regions for local consumption, agriculture or industry.
  • Increase the safe and beneficial use of desalinated seawater.
  • Commit resources to improving public health and respect the integrity of the environment with the highest ethical standards.
