Highly Efficient Electrochemical Cryogenic Purge Gas Recovery System, Phase I

Hydrogen/Helium Separation – NASA has significant needs to separate and recover hydrogen and helium from its large rocket engine test stands. Hydrogen Separation for Resource Recovery – Sustainable Innovations is working with Marshall Space Flight Center on a system that can separate and compress hydrogen from a mixed stream containing CO, methane, acetylene, ethane, and ethylene. An SBIR Phase I research program has shown that electrochemical hydrogen separation and compression is an enabling technology for the Carbon Dioxide Reduction System that facilitates further closure of the oxygen loop in an Advanced Life Support System. Pressurization for Mechanical Actuation – The NASA In-Situ Resource Utilization (ISRU) group is very interested in the utilization of hydrogen as a working fluid for mechanical actuation. In this application, hydrogen would be compressed electrochemically using the core architecture of the HRS. Reformate Separation –There is a need by NASA to convert carbon dioxide to fuels as well as convert fuels to hydrogen. As part of this collection of cycles, there is a need to separate H2 from environments containing CO, CO2, and excess fuels. Fuel Cell Energy Storage – Hydrogen/oxygen fuel cell systems are being carefully examined by NASA as a means of providing efficient energy storage for many different NASA missions. Residual helium often exists in the hydrogen tanks of these energy storage systems. Sustainable Innovations is commercializing its electrochemical hydrogen separator and compressor technology for hydrogen under the trade name H2RENEW™. Target markets for this product are: Process Hydrogen Markets: Hydrogen used as process atmosphere in industries such as metal heat treatment, electronics and semiconductor manufacturing, float glass production, and electricity production (for electric generator cooling.) Hydrogen Fueling Markets: Hydrogen used as fuel in a variety of fuel cell vehicles (FCVs) (forklifts, scooters, passenger cars, ships, etc.), stationary power and research markets. Hydrogen Tri-Generation: Separation of hydrogen from stationary fuel cell reformate, and compression for fueling (such as FCVs) applications. Hydrogen Production: Captive production, merchant production and delivery, and distributed production of hydrogen from natural gas or methane via reformer, or via electrolysis. More »
