Electrochemical methane production from CO2 for orbital and interplanetary refueling

iScience, 2021
Summary: Renewable CO2 electrosynthesis is a potentially promising tool to utilize unwanted greenhouse gas. The greatest barrier to its adoption is rendering the production of CO2-derived chemicals cost-competitive, such that they have higher net value ...

Plasma-driven water assisted CO2 methanation

IEEE Transactions on Plasma Science, 2014
By the application of pulsed corona discharges in a carbon dioxide atmosphere over a water film, the formation of methane has been observed under mild reaction conditions, without the application of a dedicated catalyst. Methane is proposed to result from hydrogenation of carbon monoxide and possibly also carbon dioxide at the NiCr alloy high-voltage ...
