How much biogas per year would a site need to produce to justify installing a unit? How much on-site labor is needed to run it?

Thanks for question! One of the benefits of our tech is we think we can go to pretty small sites and still be profitable. Our latest estimate is that a site would need to produce around 45 SCFM of biogas for us to be able to install a unit (around 14000 MMBtu/yr). Initially we will likely have an operator on-site keeping an eye on the first few units. But as we scale the idea is for these units to be automated. No la…

For a little more context. Any wastewater treatment plant treating more than 5MGD is likely to produce more than 45 SCFM of biogas.

We really need solutions like this if we are going to reverse atmospheric carbon the necessary amount to mitigate planetary catastrophe. Thanks for working on this. Good luck.

Thanks for the kind words! We appreciate it, let me know if you'd like me to add you to our newsletter. You can also sign up for it at rise-reforming.com/team.

Why biogas specifically? This should work fine with regular fossil methane, and it will de-risk your deployments. There are plenty of places in Texas that uselessly flare the natural gas instead of doing anything with it.

We do it with biogas specifically because it enables us to produce chemicals with a 90% lower carbon footprint. Our thesis has always been that when you combine cheap waste feedstocks and an efficent enough process, you could produce green chemicals that are cost competitive with the fossil alternative. Biogas is the ideal waste feedstock because it gives us a low CI, is produced 24/7 and is quite consistent in its composition. We also get it for relatively cheap.

Our process is also more efficient with CO2 so we actually like the CO2 being present.

Bro this sound's great. Have you considered deploying it to Lulling, Texas? It constantly smells like ass^Wbiofuel

If you know the name of this site I will reach out to them this week because the location is pretty ideal. Texas is the walhalla for chemicals in the U.S. so we are definitely scouting as many sites as possible in Texas. Do you happen to know the address of the site?

Congrats! I've worked on a similar technology converting waste syngas to 3-hydroxy-butyrate for further applications. Unfortunately in my case, we couldn't see any valuable and scalable end products from that particular molecule but I'm excited to follow your journey. Best of luck!

Thanks for the comment and the kind words! That does sound like a pretty cool technology! Is 3-hydroxy-butyrate a specialty chemical? Or would you also end up selling it as a commodity? What does the process look like in going from syngas to 3-hydroxy-butyrate?

It was using genetically modified bacteria via industrial fermentation. It's essentially a specialty chemical used in pharma, automotive, paints & adhesives and theoretically for biodegradable plastics but unfortunately PHB (the plastic you can make out of it) doesn't have great properties. All in all, the 3HB market was pretty small with tight supply chains and not a huge amount of growth. I'm sure you guys will have more success depending on your outputs.

I think the first priority for you should be getting _something_ built and proving your core technology. But you are making it harder for yourself by adding more variables.

Natural gas is abundant in some areas and is wasted. If you can prove that you can build cost-efficient small-scale synthesis units, then moving to biogas should later be a no-brainer.

I'm also pretty sure that you need to pre-treat the gas to remove stuff like sulfur or ammonia from it. And you can get that for "free" in places that distill the LPG from the well gas.

From a "cynical investor" point of view, it looks like you're knee-capping yourself by going for a vastly smaller market. To me this is a huge red flag, usually pointing to companies that either do green-washing, or already plan to pivot once they get the initial investment.
