Farms: Dairy Farm: Methane Digester
Productivity | Information | History | View | Quality
"Energy Conservation on the Farm at the Huls Dairy" provides information about the operation of Montana's first methane digester for a dairy operation. The project was a huge success and is currently producing enough power to run the entire dairy operation and one home. The digesters are located at the Huls Dairy Farm in Corvallis, Montana. The video shows the digesters at work using the methane gasses to produce energy. The video also explains other benefits from the installation of the digesters including commercial composting, fuel, fertilizer, and irrigation savings. The anaerobic methane digester offsets the electrical costs of the dairy operation and reduces greenhouse gas emissions at the farm. Manure from the free-stall barn is collected using alley scrapers and deposited in the methane digester. The manure is broken down through a biological process which produces methane gas. The methane gas is then used to power an engine and generator to produce electricity.

My wife Peggy was born Margaret Huls on this farm. Visiting her home-place in 1990 was my introduction to Montana. Over the years I've been privileged to witness the hands-on building of this amazing plant by the brothers themselves. This family is truly "the salt the earth" in "the home of the brave."

What do u do with the calves that r born? Don't the cows need to constantly produce calves that they don't get to feed so u can steel the milk?
Do u know that we r the only species on earth that consumes another species milk? Its not only unhealthy for us. Its inhumane to the cows. -
way to lead, utilize renueable energy as well as help clean earth...

I stopped watching at, "stops odor." I did not make it far I guess. I just hate retards who don't know shit about what they are talking about.
-
you dont i live on a dairy farm you have a hight presure hose or a yard blaster to blast the shit into a shit pond - we use our waste for watering crops farms in amarica may do this diferently
-
just reading other comments, bubble your produced gas through some h2s scavenger or water and copper sulfate solution to completely remove h2s. As well your digester ph will play a roll in your produced h2s. Although at 800,000 you shouldnt have h2s issues.
-
800,000? they saw you guys comming and generating with a V8 chevy....... oh my. :(

Thanks B Charron for your timely comments. We see some of the issues, with our swine waste methane to electricity,that you and the engineer mentioned. The hydrogen sulfide (H2S) is very corrosive and if not managed correctly will completely destroy any equipment it touches. There has to be a better and cheaper bio-gas conditioning system designed if our system is to work and last for a reasonable amount of time. We are still in the research and development stage so this is to be expected.

I was told by a well informed engineer that the problem with an Anaerobic digester/ Methane digester is that the equipment/facilities to run it are very expensive and have a very short life and are expensive to restore/replace. He said this is a great idea but in practicality you don't get much out of it, plus Methane gas is not the greatest source of energy and fails greatly in efficiency when compared to Natural gas. I guess if the government subsidizes this you can scrape up a few $ in profit

Amen! We are trying it with swine manure.

Congratulations on your dairy waste to electricity system. A beautiful farm. A beautiful family.
-
Good idea How do you make cows make a shit in a place beside the colection area
-
Thanks for an answer, I guess I should google for some schemes of smal indian methane digester.

Hulls Farm now needs to get on BioChar generation to blend with their compost and make fresh topsoil for themselves and their neighbors. Hull Family, look up Tera Preta, you're gonna like it I swear. But what you've done so far? Awesome stuff!

what is the smallest number of cows, that would payout to have something like this? 10? 15?
