    Hmm… I’m a little unconvinced by that though because natural sources for gathering methane are so much more efficient than trying to capture it as a result of, say, fracking or farming.

    I get it’s a useful fuel, but it’s also cheap and abundant. CO2 capture is easier than CH4 capture, per the article, so combusting difficult to capture methane at the source into easier to deal with CO2 seems like a no brainer.

    But also I’m a biologist not a climate scientist so 🤷‍♂️

      I was thinking about point sources, like industrial processes that would normally outgas methane. On the other hand, flaring methane from natural and/or non-point sources is pretty much impossible (natural “will-o-wisps” notwithstanding).

      I would guess that, at least theoretically, there’s some level of concentration of methane below which it’d be better to use air-conversion to CO2 via zeolites vs. point-source capture.
