This company is working to produce a machine that produces methane from waste electricity, water, and atmospheric air.

I searched for this company and only found a few references from several years ago.

I’m always skeptical of these bold claims, and my skepticism for something useful is still here with this company.

That said, from all of their public press and their description of their approach and goals, there could be something here. Time will tell.

The most important aspect of their approach is that they make no claim of this being energy efficient. Quite the opposite. They say it takes about 300% more energy input into their process than results from the energy in the methane that comes out.

Why this still looks like a possible viable path, is that they are building this to consume overproduced electricity that cannot otherwise be used or stored. As in, put it at a solar farm where the utility is rejecting more energy at the height of a sunny day (because of overcapacity).

I like how they’ve broken the technological challenges down into three main parts:

  • input CO2 source
  • input H2 source
  • methane formation step.

Further, they’re building out their product to ship on container skids, so deployment (or redeployment) doesn’t have the same permanent infrastructure requirements a virgin build might (such as pouring concrete, etc). They also claim to not require any exotic materials for any of their steps.

Lastly, what give me the most confidence is in April 2024 they have already built a working prototype of their tech and produced synthetic methane from it and sold it to a utility company! I fully recognize that have a working prototype doesn’t mean that that their approach can scale to anything useful, but I give them credit for recognizing the shortcomings of their approach while still producing a prototype that does what it claims to do: Produce methane from waste electricity, water, and atmospheric air.

    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…

            Now, what ever happened to regularly riding horses around?

            Besides the issue with horse excrement, other issues occurred (Hayden, 2016):

Dead horses often clogged city streets;
In New York City in 1880, 15,000 horses died on the streets, or 41 dead horses a day (which had to be removed);
Some place to stable the 100,000+ horses that operated within New York, and food to feed them;
On a per capita basis, 19th century horse-drawn vehicle accident rates were similar to those of the automobile in the 20th century.

              Fair enough. They do have an easy solution for horse shit, they’re basically called shit bags, which you mount on the horse’s ass to wear.

              As far as dead horses, well I’m not exactly sure what to do with those, but then again I’m not sure what to do with all the dead/totalled vehicles out there either.

              Out in the country, we’d just haul dead horses to ‘bone hill’, as they called it. Hey, it’s no worse than a cemetery, except the exposed carcasses stinking up the area, but bone hill was well away from anyone’s house.

              Speaking of wasted land, why do humans like to collect dead bodies and waste land space?
