Cameraman keeps shaking the camera like he is dancing. 3. Presenter points to pipelines. Cameraman shows pipes and knobs. 4. Presenter points to the boiler. cameraman is reluctant to move the camera to the boiler.

Great Video, I swear im a biogas junkie lol, I have built three small home digesters which i run a small generator. Thanks.

[@m_paya8180]

pls i would love to learn how you did it [phone] my whatsapp thank you

[@cvillan-reb3675]

Tell me how you did that??? Id love to pick your brain. [e-mail]

[@nonyabusiness9747]

Hi there David. I have two IBC totes and I plan on connecting a series of 50 gallon drums to filter water. In the thought of harvesting the gas off the system, Should I be thinking about how I might contain a bladder? Say this watered I have stored away..?

[@preranarabha2212]

Beautiful biogas plant

How many cubic meter size of Biogas can power 10kw gen 24 hours a day

[@genobee99]

5 meter cubic per day

[@UKsystems]

You may need to work out specifics for manufacturers as the kilowatts I assume you’re referring to the electrical power produced which would be vastly different amounts based on efficiency and a few few other things because if you don’t run it at its full efficiency because you’re not at the optimal load it’s going to be different that’s why I personally would charge batteries and running inverter so they can always take the generators most efficient power load and then shut it off when they’re charged

[@riippumatonlinja]

Question stays, how much for unit and how long it takes to pay itself back? Also how longly one can operate? For industial size generator can easily cost 10 000, lifting truck another, and whole unit propagly six digits?

[@nascorob]

What is the cost of this setup in Sterling ?

[@jessew6757]

Hi Michael. I’m impressed by your Evergreen biogas to Biomethane setup. I would like to ask if it’s possible to purchase a similar setup with complete Biogas scrubbing, compressor setup and storage storage system. The target is to have a Biogas upgrade system that processes Biogas generated from Biogas digester that uses large scale Pig farm manure and the feedstock. Did you build your own compressor and scrubber or did you purchase it ? Regards, Jesse

[@0629frank]

It depends on the electric generator, for example a 600 watt one consumes 0.75 cubic meters of methane to generate 1 kWh.

[@joshuazeledon1323]

Hi, I have Methane in Our Well Water, I am looking into how to harvest it. Any help you could provide?

[@danieljbence5764]

Not sure how green this actually is there seems to be a lot of power being used in the production I would think the surge load on all the motors would need to be grid supplemented or large solar array. So just swapping 1 for 1

[@aidencraigallman1656]

Why are these sort of systems not being used by waste water companies to provide a clean source of biofuel for cars? Would digested human waste gas such as methane be as calorific as useful as biogas developed from food waste feed?

[@michaelconchuir6523]

They all could do this, they could produce biogas, ecocrete building blocks (first invented in Japan a decade or so ago) as well as generate electricity or believe it or not grow veg via an Aquaponics type system, although I'm not sure if veg grown in a sewage works site would catch on though lol 😂😂😉

[@andrewmottram8596]

They are. Most reasonable size Waste Water Treatment Plant in the UK have their own small generation facility which runs the sewage treatment process and the admin buildings and the excess is exported to the electricity grid.

[@billrodriguez7561]

All that fuss for 7 kW? Not useful.

[@UKsystems]

@@billrodriguez7561 you failed to realise that it’s 7 kW continuously 24 seven it’s not a lot but it is essentially an initial investment. It’s also worth knowing that it could be when used on waste water treatment plants collecting the methane given off instead of running a process just to generate the meeting, which would be a lot more efficient.

[@garethlloyd9718]

Although this is a research plant and the biogas is separated into different streams if it was used purely to power a chp generator how many kw would this size of plant support. I'm just trying to get an idea of scale because most AD setups seen in the UK are on farms where space isn't a consideration. This is a very compact and tidy installation 👍

[@murthyiyer]

Could you produce more electricity? Enough to power a community of 2,000 homes 24/7?

[@charlibravo371]

Absolutely not. The generator they have is a 7kwh system. Hardly enough to power one house.

[@tonymckeage1028]

Great Video, I'm very interested in farm scale operations digesting cowshed effluent from 500-1000 cows, thanks for sharing

[@sweetbone96]

Hi, very interesresting video. My qyuestion is, the "compost-like material" that is produced, wont it be lacking in nitrogen because of the methane that is formed from the nitrogen?

[@agritech802]

There's no nitrogen in methane, it's just CH4

[@matsvineyard7564]

Completed compost does not neccesarily contain lots of nitrogen. The main aim of good compost is Humus.

[@brianbirir9695]

Is the generator you are using commercially available can someone buy it ?

[@UKsystems]

Anyone can buy anything if they have enough money these generators are semi available because most generators sold as being compatible or just standard natural gas generators and they don’t cope particularly well with it at start-up but they work may need something to start up on another fuel, if there are issues

[@ericlotze7724]

could you convert the hydogen sulpide into sulphuric acid? I know some coal based syngas "gassworks" did this.

[@vincesandoval8972]

I think if you bubble the gas through distilled water b4 the scrubbers.good idea ima borrow it

[@apinhmi]

Nice video. Great work man. Question:. What is better, 1 big system like 10tonner bio digester or 10 smaller system of 1 tonner container? Appreciate you very well thought of response. Thank you! GBU! Farm produces 15 tonner chicken dung.

[@tigertoxins584]

DAefinitely a bigger one, though the smaller ones sound aesthetically appealing. I don't know anything about bio gas plants but using common sense, I can tell you that more units = more repairs, more power loss. It also seems cheaper to build one big one and takes up less ground space too.

[@Biogaschannel]

Hi Jesse, If you are looking for information about biogas and biomethane technologies, please write to [e-mail]. We would be glad to help you!

[@MolitorQH]

i am looking for a system like this. is it available?

[@scottledeuce]

Looks great but would the same system work as efficiently with manure instead of grass I wonder.

[@FreshWitDiceInMirror]

These systems are used with great success on farms with cows, using cow manure

[@brightmal]

It works fine, but you get far less gas per tonne of solids. About 25 cubic metres per tonne of cow manure, and about 125 cubic meters per tonne of grass and such. Food waste is even better, at about 376 cubic metres per tonne. It all depends on how many calories the feedstock contains.

[@brightmal]

To be fair, those numbers are the smallest numbers I've found so far. Plenty of groups get a lot more gas per tonne than that. Some digesters are better than others, and some are simply operated better than others. For example, if you try to pump too much material through the digester too fast, you won't get as much gas out of it.

[@JustinBerlin8191]

Is it common to have two digestion chambers to increase capacity and utilization of the organic material? I have an idea that would, post digester, drop the material into an aerated container before transferring the top third of that container into a clarification tank so that the top third of that could then be transferred to an artificial wetlands with farmed fish. Would this be an efficient method of treating large amounts of organic waste? Will this process reduce the nitrogen/phosphorus load within acceptable levels for fish farming and human contact?

[@monkeymonkey35]

@@brightmal Hello Mark do you have any sugestion of any paper that can give me a reference to the figure? I would like to start a biogas project, and I need a proper and trusted reference.

[@ianwoolley1770]

Have u ever used horse manure in ur digerster

[@tiagofigueiro]

I wonder if you have any estimates on average kWh_biogas/kg_waste from the generator and boiler output logs?

[@RikkerdHZ]

This depends a lot on the type of waste you have. Fats have much higher biogas production potential than for example cow manure. A ton of glycerol can produce up to 647 m^3 biogas per ton (1000kg). A ton of cow manure produces only 27 m^3 biogas.

[@KovietUnionDefector]

It is only nice compost if the grass comes from NON Roundup-ed fields. Compost made from grass treated with roundup will kill any of the plants you try to grow in it. I know from experience from an allotment taking compost from a plant which took municiple grass clippings which had been treated with round-up herbicide.

[@matsvineyard7564]

That is not true. The roundup will break down. Probably some other broadleaf herbicide such as MCPA. If Grass was treated with roundup it wouldn't be grass anymore. It would be dead.

[@martinamadsen812]

Seems that there is plenty of scope for expanding this technology, but it still require oxygen from the air in order to utilize the gas.🤔 Hydrogen produced by electrolyces using solar, wind or water flow to generate the required electricity, and the hydrogen gas from water that then can be stored and when combusted it will use equivalent oxygen to what was released when the water molecules was split by the electricity, so the worlds finite oxygen levels in the atmosphere etc, is not affected, nor is undesirable compounds produced, as from carbon based fuel usage - when clean "green" hydrogen gas is used for combustion.!☺

[@paulishism]

What's the environmental impact of releasing H2S into the atmosphere?

[@nesiansides7133]

It's actually carbon neutral because the substrate used is replaced by the feedstock it was removed from ie grass, maize, seaweed, etc. Fossil fuels has no replacement thus continously accumulation of emissions consistently and currently no signs of stopping.

[@paulishism]

@@nesiansides7133 there's no carbon in H2S.

[@nesiansides7133]

@paulishism removed via H2S/Co2 scrubber filters, usually with metal wool, lime catalyst, which biogas fed thru aquarium aeration stones. Most off grid farms use low-tech components.

[@paulishism]

@@nesiansides7133 I didn't ask how to remove H2S from biogas.

[@Camille_Boomer77000]

I thought that was cool until the part about methane being released into the atmosphere which is what I was hoping would be solved in a way or another to truly produce green energy.

[@ozciva]

Carbondioxide and hydrogen sulfate, I believe, are released to atmosphere, not the methane.

[@prajnaseek]

Biogas is extremely positive in terms of the environment, but it is only ethical under certain conditions. It must only be used with manure, food waste or farm waste products as inputs, and should never burn food crops or garbage, nor use crop land or forests for biogas fuel. Secondly, the solid and liquid natural fertilizer produced needs to be returned to the soil, of course. Given these strict use parameters, biogas is a good thing. Break any of these rules, as is the current norm, and biogas is sheer destruction.
