Microwave regenerative sorption media gas storage/delivery techniques are proposed to address both compressed gas management and hydrogen purification requirements in support of crewed deep space exploration missions. By reducing or eliminating the need for a conventional gas compressor, both the crew habitat noise level and required storage pressure for important Air Revitalization (AR) gases, such as oxygen and carbon dioxide, are reduced by using this technology. In addition, with slight modifications, the same concept can be used to serve as a regenerable hydrogen gas purifier. In either application, the penetrative nature of microwave heating is utilized to efficiently drive gas desorption from physical sorbents. For the compressorless gas storage application, the microwave desorption step supplies pressurized gas to downstream processes. Similarly, for application as a hydrogen purifier, microwave heating drives off captured contaminants from the sorbent bed (which is held at relative vacuum) during regeneration. Potential contaminants present in the hydrogen stream include water vapor, carbon monoxide and various hydrocarbons (including methane, acetylene, ethane, and ethylene).
