Microwave Plasma Hydrogen Recovery System

A microwave plasma reactor was developed for the recovery of hydrogen contained within waste methane produced by Carbon Dioxide Reduction Assembly (CRA), which reclaims oxygen from carbon dioxide. NASA can incorporate the innovation into flight hardware systems for deployment in support of future long-duration exploration objectives.

Sustainable Biochar to Mitigate Climate Change

By producing biochar - a charcoal-like substance made from plants and other organic materials - up to 12 percent of the world's human-caused greenhouse gas emissions could be sustainably offset, which is more than what could be offset if the same plants and materials were burned to generate energy.
