    • Concept for Increasing Water Recovery by Use of Series Reverse Water-Gas Shift - Sabatier Technology 

      Portner, Benjamin; Schnaitmann, Jonas (46th International Conference on Environmental Systems, 2016-07-10)
      A novel concept for increasing the water yield from existing Sabatier technology is proposed. Current Sabatier technology on board the ISS uses electrolysis hydrogen and metabolic carbon dioxide to recover water used for ...
    • Hydrogen Recovery by Methane Pyrolysis to Elemental Carbon 

      Stephen Yates; Amanda Childers; Nicholas Brom; Charles Lo; Sean Skomurski; Morgan Abney (49th International Conference on Environmental Systems, 2019-07-07)
      Use of a Sabatier reactor to recover the oxygen from the carbon dioxide exhaled by the crew on the International Space Station has been limited by the loss of the hydrogen contained in the methane it generates. Maximizing ...
    • Methane Post-Processing and Hydrogen Separation for Spacecraft Oxygen Loop Closure 

      Zach Greenwood; Morgan Abney; Lee Miller; Terry Wall (47th International Conference on Environmental Systems, 2017-07-16)
      State-of-the-art life support oxygen recovery technology on the International Space Station is based on the Sabatier reaction where only about half of the oxygen required for the crew is recovered from metabolic carbon ...
    • MOXIE Development Driven Prospects For ISRU and Atmosphere Revitalization 

      Hartvigsen, Joseph; Elangovan, S.; Frost, Lyman (48th International Conference on Environmental Systems, 2018-07-08)
      The founders of OxEon Energy led the solid oxide electrolysis (SOXE) stack development for the Mars 2020 MOXIE experiment. MOXIE, the Mars Oxygen ISRU Experiment was developed to demonstrate oxygen production by direct ...
    • OxEon Energy Demonstration of Manned-Mission Scale ISRU Process Systems 

      Joseph Hartvigsen; S. Elangovan; Lyman Frost (49th International Conference on Environmental Systems, 2019-07-07)
      Since delivering the Solid OXide Electrolysis (SOXE) stacks for the Mars 2020 MOXIE project in 2017, the OxEon team has designed and begun fabricating SOXE stacks of the cell area required for a manned Mars mission. The ...
    • Results from the Plasma Pyrolysis Assembly (PPA) Zero-g Flight Experiment 

      Richard Wheeler; John Holtsnider; Ryan Olson; Ross Dewberry; Zachary Greenwood; Cara Black (49th International Conference on Environmental Systems, 2019-07-07)
      Results of zero-g validation testing of a microwave powered Plasma Pyrolysis Assembly (PPA) are presented. The PPA recovers 75% of the hydrogen from methane which is produced by a Sabatier reactor. PPA efficacy has been ...
    • Sabatier System Design Study for a Mars ISRU Propellant Production Plant 

      Hintze, Paul; Meier, Anne; Shah, Malay (48th International Conference on Environmental Systems, 2018-07-08)
      As NASA looks towards human missions to Mars, an effort has started to advance the technology of a Mars ISRU Propellant Production Plant for a flight demonstration. This paper will present a design study of the Sabatier ...
    • Solid Oxide Electrolysis and Nafion System Architecture for Oxygen Recovery and Fuel Production 

      Iacomini, Christie; Finger, Barry (46th International Conference on Environmental Systems, 2016-07-10)
      Solid Oxide Electrolysis is a technology that can generate oxygen from water vapor and carbon dioxide. Embedding Sabatier reactors allows for reclaiming oxygen from carbon monoxide produced by electrolysis as well as ...
    • State of NASA Oxygen Recovery 

      Greenwood, Zach; Abney, Morgan; Stanley, Christine; Brown, Brittany; Fox, Eric (48th International Conference on Environmental Systems, 2018-07-08)
      Life support is a critical function of any crewed space vehicle or habitat. One of the key elements of life support is the provision of oxygen to the crew. For missions close to Earth oxygen may be resupplied from the ...
    • Study of Sabatier Catalyst Performance for a Mars ISRU Propellant Production Plant 

      Carolina Franco; Robert Devor; Sarah J. Snyder; Elspeth M. Petersen; Paul Hintze (49th International Conference on Environmental Systems, 2019-07-07)
      NASA is currently developing technologies for use in the field of in-situ resource utilization (ISRU). One of the technologies being advanced is the Sabatier, or methanation, reactor which converts carbon dioxide and ...
