Common Core Technology

At the core of its technology is Sustainable Innovations’ patent-pending, high-pressure electrochemical module that serves as the foundation 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. Each of our three product lines use the same core technology and leverage a single platform to perform their varying functions.

Our products are targeted to serve global, high value, near-term applications: recycling process waste hydrogen streams and generating hydrogen, grid scale energy storage, and recycling CO2 into high-value fuels and chemicals.


High Pressure Electrochemical Cell Modules

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. Electrochemical compression of hydrogen to high pressure levels provides the most effective means for practical hydrogen storage and eliminates the need for expensive, inefficient mechanical compressors. High pressure capability is critically important for hydrogen fueling applications, energy storage using hydrogen, and in the reduction of CO2 into hydrocarbon fuels and chemicals.


Expandable Modular Architecture

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 capture and utilization.
