Does anyone know if there is anyone researching on CH4 (Methane) sequestration? While it's concentration is vastly lower than CO2 (around 1.6ppm vs >400 ppm CO2) it still has roughly a quarter of the impact of the atmospheric CO2. It has a rather short half-life (8-12 years) in the atmosphere yet the concentration is still is rising, even at an increased rate recently with no definite explanation (might be wetlands emitting it at a higher rate, might be melting permafrost soil in the arctic, might be a result of fracking). I don't think it is commercially viable to do it but it might become a sheer necessity if we run into some positive feedback loops so having at least some basic research going on in that field might not hurt.
- neural_thing 7y agoI've only seen capture at the point of production for methane. See Lanzatech, for example.
- aurelwu 7y agohad trouble finding much on their homepage but : https://www.lanzatech.com/2013/09/20/lanzatech-awarded-4-million-grant-from-arpa-e-to-transform-waste-methane-resources-into-low-carbon-fuels-and-chemicals/ https://www.lanzatech.com/2013/09/20/lanzatech-awarded-4-mil... has at least some more information about it, thanks for the hint :-)
- konschubert 7y agoMaybe there are techniques to shorten its half-life?
- danieltillett 7y agoI think it has been suggested lasers can work, don't know how realistic this is.
