Interesting. My question, is a 12v .2 hp 150psi compressor motor enough to compress the bio gas? If it is you can solar panel the walls or roof of your reactor to continue the “free” cycle

Not sure how much experience with those compressors you have, but you want to use ice water for the cooling, I actually use freezer packs and RV anti-freeze, dropped my head temp almost 10 degrees over ice water.

ice the propane tank like you would do for a keg of beer this will help condensed the gas! this process helped me with saving some of the r134a Freon the concept is the same for any gas! vaper!

What materials do you use for the filtration?

Sir the kalburo and aciton carbon are also used for production of asetellin

Bro we are in the twenties right now

Yes its efficient to compress if you are doing it for commercial meaning for selling it for the following reasons; Storage: Compressing biogas allows for efficient storage in a smaller volume, making it easier to transport and use where needed. To demonstrate that compressing biogas allows for efficient storage in a smaller volume, we can use the ideal gas law equation: 𝑃 𝑉 = 𝑛 𝑅 𝑇 PV=nRT Where: 𝑃 P is the pressure of the gas, 𝑉 V is the volume of the gas, 𝑛 n is the amount of gas in moles, 𝑅 R is the gas constant, and 𝑇 T is the temperature of the gas. Let's consider an initial state of uncompressed biogas and a final state of compressed biogas: For uncompressed biogas: Initial pressure: P1 Initial volume: V1 ​Initial amount of gas: 𝑛 Initial temperature: 𝑇 For compressed biogas: Final pressure: P2( higher than P1) ​ Final volume: V2( smaller than V1) Amount of gas remains the same: 𝑛 Temperature remains the same: 𝑇 Using the ideal gas law equation for both states you get what I'm saying ..........my apology for not completing the calculations ​Therefore, by compressing biogas and increasing its pressure, you can store the same amount of gas in a smaller volume, enabling more efficient storage and transportation of biogas. Share Energy Density: Compressing biogas increases its energy density, making it more practical for various applications such as transportation fuel or heating. Reduced Transport Costs: By compressing biogas, transportation costs can be reduced since more gas can be transported in a single trip. Increased Usability: Compressed biogas can be more easily integrated into existing natural gas infrastructure for use in homes, businesses, and vehicles. Environmental Benefits: Biogas is a renewable energy source that can be produced from organic waste. By compressing it efficiently, it can be used as a cleaner alternative to fossil fuels, reducing greenhouse gas emissions.

Awesome video! Could you please tell me the exact size of the "smallest drill bit I own?" Recommend you put that in the description. I was worried the small bit of gas in the hose might ignite when you started drilling. I would have been too scared to do that and would have disconnected it from the other side.

thanks for this video its very good

You could put a vacuum on the tank with a ac compressor 😊

thanks for sharing your knowledge about biogas!

Clever way of both setting the slurry level and tapping into the middle digestate layer with that rotate technique in your build.

Buddy you got to automate that prosses

So how long will it heat on one tank of fuel?

Excellent

Okay, the point that jumps out to me here is that the liquid level on the Solar cities design should actually be a few inches lower than the top of the IBC. The key here is closing the gas tap every time you add new substrate. The gas pressure inside stops the liquid level from rising, and the only way for the overflow to go is the digestate outlet pipe. I've built one with this design, and it works, at least in the summer.

That was very clever. Good work man.

❤❤❤❤ incredible, can do a video on how to use fridge compressor instead

You can try quicklime as filter

Propane fittings are available on Amazon all day, every day.

Your Intro already got me! Good job man.

Thanks for sharing the info!

Bro you still did a good job filming and explaining a big thanks for that

Ty so much just learned about h2s tday~

Great 1st question

Man i love the idea of concenverting one residential home septic tank into a biodigester tank that creates free Biogas! I think a local cow farm created an underground methane tank They decided to connect their biogas to a power generator and create another stream of income for their business by selling power back to the grid 🌟 🤩 🌟

Same! Ty for building a whole channel on this topic!

greetings from southern Brasil

Do you have a link for the filter housings?

what type of compress I can use?? for example can I sue regulare air compressor?? I have concen with igniting the methan as I compress the gas?? any feed back would be appreciated

This is a great resource.

I calculated energy consumption for filling a high pressure 4500PSI tank, it would take about 8Kwh to fill a 33L tank. That tank would contain about 100Kwh of energy if it were 90% methane, if I were to use that methane on a 40% efficient generator (very optimistic) and then use the energy from that generator to power the compressor, I would require 20Kwh of my gas to do so. Meaning to store 100Kwh of 90% methane gas at 4500psi I waste 20% of the energy of the gas. It's an ok number, the problem comes when you realize biogas is not 90% methane, but much less.

If you know someone with a biogas digester, you can also use a sample from his/her digested fluid 👍

Poop

I presume the biogas is all methane and has less calorific value than propane, hence you need to up the flow rate?

why not have a presser relief valve in place of the bubbler. Also you could have the compressor attached permanently. have a valve between the digester and the gas storage area. so they digester does not end up with vacuum. hope that can help out have a 2 or 3 bar presser relief valve 2 bar is 29 psi and 3 bar is 43 psi

I am a CNG/LPG kit installer by profession and I compressed my biogas and run my cng car with it. Only thing you have to do is tune the kit a little richer just like you did with your stove/burner to compensate for the leaner gas. You get just a little less power but it works fine. My concern is that biogas has a small percentage of Hydrogen that might make the steel tanks brittle overtime and they might explode eventually under pressure. I have type 4 carbon cng tanks but am still afraid to use them as they are not rated for hydrogen. I have seen videos of cng tanks exploding and I don't want to experience this so I stopped doing it. If you can find a way to get rid of H2 then that would be great. They say that H2 molecule is so small that it goes through any tank even steel ones so I guess that by the time I compress it into my tank it should have already escape but I am not sure as I have no way to measure H2 content.

If you use solar panels to power the compressor then I guess it's fine, otherwise you would have to change your car with a new electric one.

Hey it's your long lost buddy you gifted the black German Shepherd to in NC. I switched phones and need to track down your number. Haha. Nice channel!

Sorry, I can't answer any questions here. I have one myself though.. the f..k is your neighbor up to, are they just f'n with you. Also, thanks for the videos!

Thanks for the videos. Quite educating and unique 👍. What do you intend using as a as an extenal storage system for your gas? I had to shut down my first digester due to inavailability of a gas bag..... Biogas technology is not very common in Nigeria making Biogas accessories very expensive.

Great video! I have followed your channel for a while and have finally started to build a digester. I’m going with the ibc tote design from solar city. I appreciate all your videos. I feel like I remember you mentioned hoping to run a car on biogas, did I remember that correctly? Have you experimented with that at all?

I guess moisture is a big problem. If you rust your gas tank from the inside you'll blow yourself Up...

Being on 100% solar, pumping biogas or splitting H20 with solar electricity does me no loss.

Amazing 🤗.... Where you got really crazy 😧 ( 09:16 Sec) ....... Triggered my comment 😊........ Because I've thought of this several times. Infact, thought I was the only one with this crazy thought in the world 😅. "Pursuing my degree in Microbiology"

hey sounds like you opened pandoras bio-digester (; I think this time I can help with some of the questions you brought up , first I've read in a few places and it's my understanding that there are two parts to metanogenisis (the biological creation of methane) the first is the break down of organic molecules (the wast being fed) in to acetic acid or other anaerobic carbon based molecules, this part can be done by "other bugs" and my be more efficient with more specific bacteria or archea, the second part of the process is the actual formation of methane with the consumption of the acetic acid and production of methane. there is a "delicate" balance between the to stages because the first creates acid wich lowers the ph wile the second part is limited to a more ph neutral environment, that's why you can't put to much feed at once or it will all go acidic and the process will stop , in a healthy digester the methane production (literally) eats the acidic molecules creating a balanced . on the part of sterilizing and having a specific culture to my perspective it will not help and probably counter productive as bacteria and archea all have a wide range of biological pathways, meaning thay can do meny different things that create meny different biological compounds like from co2 to metanol acitic acid and meny others , mostly it depends on the chemical conditions thay are found in, so sterling and selecting will not help so much, what more thay are geneticly very flexible so its not like you have a chicken in a pen and you know it will stay a chicken tomorrow, with archea you can come back tomorrow and find a walrus in sted of a chicken. the bio-digester is actually an ecosystem with all the principles of ecosystems applying to it, so it thrives on diversity and is defind by the conditions that are present. I'll share my one (bad) ideas on dealing with the co2 , and oxygen , first as a biology geek I was thinking of organisms that take in co2 and obviously plants and defrent photosynthesisers take in co2 , and thay also produces oxygen as a by product, wich can make a very flammable combination of methane and oxygen gas , on the other hand there are some plants like different kinds of cactus 🌵 that take in co2 and release oxygen at different times and may help filter out the co2 it needs more research, and for the oxygen it reacts with iron in the proses of rust so maybe if the material is fed through some rusted iron it will absorb the oxygen before it gets in the digester.

Just wondering. Is there a reason you're sucking the gas through the filters backwards? I guess it doesn't matter with the filter media you're using. Just seeing that you're going against the flow arrows on the filters triggered my ocd, lol!

About how long do you figure you can run that heater off that tank if it was full? And how many PSI do you put in the tank? Thanks

I love to see you do another compressing video
