Bio-Electrochemical Carbon Dioxide Removal for Air Revitalization in Exploration Life Support Systems, Phase I

Completed Technology Project

Project Introduction

Bio-Electrochemical Carbon Dioxide Removal for Air Revitalization in Exploration Life Support Systems, Phase I
An important aspect of the ISS air revitalization system for life support is the removal of carbon dioxide from cabin air and retrieves oxygen from CO2. The current state of art technology for CO2 reduction is Sabatier reaction, which is energy intensive and results in excess CO2. Cambrian Innovation has developed an electromethanogenesis bio-electrochemical system (BES) that is focused on reducing costs associated with CO2 reduction. The two-chambered BES system is designed to operate by producing a reliable stream of O2 while simultaneously bio-electrochemically reducing CO2 to CH4 and H2O. Phase I experiments and analysis will be used to determine whether it will be feasible to develop a cell which can replace the existing Sabatier reactor. Through Phase II and Phase III R&D we hope to develop and test a BES CO2 removal system for potential utilization aboard the ISS or related crewed systems. More »
