Sustainable Innovations is developing products for critical energy and industrial applications having tremendous global commercial and societal value. At the core of its technology is Sustainable Innovations’ patent-pending, high-pressure electrochemical module that serves as a key enabler for its products. Sustainable Innovations has taken Proton Exchange Membrane (PEM) technology, originated in the 1950’s and used in space programs since the 1960’s, to a new level through a set of unique, proprietary innovations. Sustainable Innovations has developed and demonstrated an electrochemical cell stack architecture that allows for energy efficient hydrogen compression up to 13,000 psi, an order of magnitude higher than the capability of other PEM systems. Our high-pressure electrochemical cell stack is the enabling technology and common basis for all of Sustainable Innovations’ products. The ability to electrochemically compress hydrogen to high pressure levels provides the most effective means for practical hydrogen storage and eliminates the need for expensive, inefficient mechanical compressors. Sustainable Innovations is addressing the high cost of large scale PEM electrochemical cell stacks through the development of an innovative expandable modular architecture (EMA). The EMA provides a means of creating a cell stack that is customizable and scalable for use in any of our products. It is designed to be fabricated using low-cost rolled materials and inexpensive components supplied through high-volume manufacturing processes. The EMA enables high pressure system operation, making it possible for new, high-value processes to be commercialized in the fields of hydrogen separation and compression, grid-scale energy storage, and CO2.
