ISRU-derived water purification and Hydrogen Oxygen Production (IHOP)
Paragon’s flagship ISRU system, IHOP, is funded by a NASA NextSTEP-2 In-Situ Resource Utilization (ISRU) Technology contract. IHOP combines the critical ISRU functions of water purification and electrolysis into an integrated system optimized for lunar water processing and capable of the same on Mars. IHOP receives water from mixed ices found in Permanently Shadowed Regions (PSRs) on the lunar poles, purifies the water of co-located toxic and corrosive volatile contaminants, and generates hydrogen and oxygen that from the electrolysis of that water. The product hydrogen and oxygen can be used as propellant for lunar transportation vehicles (ascent and landers), reusable cislunar transports, and human missions to Mars and beyond. Technologies that can make use of the IHOP consumable products include fuel cells, crew atmosphere revitalization, and crew potable water.
