Highly Efficient, Solid State Hydrogen Purification for Resource Recovery

Completed Technology Project

Project Description

Highly Efficient, Solid State Hydrogen Purification for Resource Recovery Project Image
Sustainable Innovations' signature electrochemical cell architecture provides a solution to NASA's search for regenerative separation technology enabling maximum hydrogen recovery from a stream containing water vapor (saturated), carbon monoxide (CO), and hydrocarbons including methane, acetylene, ethane, and ethylene, among others. Separation of hydrogen from mixed gaseous streams presents a significant technical challenge for various NASA applications. In addition, the ability to efficiently perform hydrogen purification presents an attractive economic opportunity. Sustainable Innovations is developing a technology that extracts hydrogen from a mixed stream by electro-oxidization of the hydrogen and subsequent electro-reduction of the resultant protons in a separate chamber. The process, when combined with an electrochemical cell architecture that is engineered to tolerate high differential pressure, can be used to separate and compress hydrogen in a single step. The process is proven to be efficient, quiet, and highly reliable. It requires no reciprocating compressor, so it is largely maintenance free. More »
