Comment on Terraform Industries actually created synthetic methane from sunlight, water, and air

  It’s useful because (besides displacing fossil methane) it’s a stepping-stone to producing methanol, which can be used to produce propane, which has a lower greenhouse coefficient per gram than CO2 (and also displaces fossil methane).

  Confused, how is this useful?

  There are many MANY useful applications of carbon neutral methane. The most beneficial and obvious to me are:

  • Useful method of storing excess generated solar and wind power
  • Entire industries, markets, and infrastructure already existing for the storage, transportation, and consumption of methane

  You can get methane out of a cow’s ass all day long

  You cannot get pipeline grade methane out of cows ass, and even if you could, you wouldn’t have the technology to capture it for use in the marketplace in any quantity that would be cost effective against fossil fuel based methane. As in, even if you could (and you can’t), it would cost so much that no one would buy it and instead just pull more out of the ground. The solution proposed here is on the path to being worth skipping the fossil fuel route for methane and using this instead.

  and methane is a greenhouse gas,

  So is the CO2 that is being used as the feedstock to create the methane. This would be reducing atmospheric CO2, which I hope you would agree is a useful element when directly combating climate change from C02 emissions.

  I thought we wanted less methane, not more.

  This wouldn’t be producing net more methane. The market is already consuming all of methane it demands. This would replace some of the supply that is currently being fulfilled by carbon positive fossil fuel sources.

    Interesting. Guess you’ve never heard of a fistulated cow before, they can totally connect tubing or pipes to cows to harvest methane straight out of their intestines.

    I’ll leave it to you wonderful people out there to look up what a fistulated cow is. Disclaimer, it’s a bit disturbing.

      Guess you’ve never heard of a fistulated cow before, they can totally connect tubing or pipes to cows to harvest methane straight out of their intestines.

      And the cost for fistulating each cow? And how much methane will such a cow produce? How contaminated will the methane be? What methods would be required to refine it to pipeline grade? Further, can you feed a cow with the output overproduction of a PV solar panel?

      This is what I meant when I said cows wouldn’t be economically viable sources of methane from electricity. If you think cows are they, then I won’t stop you though.

        Now see, this is the kind of content I like to see, informative and educational banter, with thoughts, opinions, and relevant links 👍

        Now, what ever happened to regularly riding horses around? I mean hell, they’re self-fueled lawnmowers that double as transportation…
