Highly Efficient Solid Oxide Electrolyzer & Sabatier System, Phase I

Completed Technology Project

Project Introduction

Paragon Space Development Corporation® (Paragon) and ENrG Incorporated (ENrG) are teaming to provide a highly efficient reactor for carbon monoxide/carbon dioxide (CO/CO2) conversion into methane (CH4). The system is a gravity-independent, compact, leak-tight, Solid Oxide Electrolyzer (SOE) system with embedded Sabatier reactors (ESR). Utilizing Corning Incorporated (Corning) Intellectual Property (IP), ENrG and Paragon can leverage an all-ceramic, efficient, and low mass solid oxide fuel cell (SOFC) that remains leak-tight after hundreds of thermal cycles. Paragon proposes that incorporation of the all-ceramic technology into our SOE/ESR system will result in a robust design solution that will: 1) be thermally shock tolerant and capable of hundreds of on-off cycles at faster cycles than compared to the metal-to-ceramic SOE designs, 2) be lighter, smaller, and require less power than existing designs, 3) allow for high (>90%) single pass utilization of feedstock, and 4) achieve a thermodynamic efficiency of up to 80%. Our Phase I effort includes laboratory tests to determine the feasibility of employing the all-ceramic SOFC design as both an electrolyzer cell and an ESR to improve single pass utilization of the feed stock and deter carbon deposition. Integrating cells that operate as either an electrolyzer or a Sabatier reactor simplifies operations, lowers hardware complexity, and increases reliability. The proposed system can perform multiple functions without modifications, making it a readily deployable technology for various missions from ISRU on the Moon and Mars to regenerating 100% of a crew's oxygen while in transit.
