Project Description

Electrochemical Dehumidification and Life Support System
Sustainable Innovations has developed an innovative concept for highly efficient, reliable, potable water production based on technology from a commercial line of hydrogen recovery and compression systems the company is developing. This Electrochemical Dehumidification and Life Support System (EDLS) system utilizes a small amount of hydrogen as a working fluid, operating in a sealed cavity, and leverages a hydrogen compression cycle to provide the driving force to both remove water from the local environment, passing it into a dry hydrogen stream, and condense pure, potable drinking water. The hydrogen compression cycle used in this process is highly efficient, approaching the efficiency of an ideal isothermal compression process, and can be achieved without moving parts. This technology could play a key role in critical NASA environmental control and life support applications. More »
