Biogas and anaerobic digestion of manure in Jühnde

[Cuicui]

Thursday 9 February 2006 to 20h, news about Arte, superb report on a methane production facility (heating and electricity) in the village of Jühnde in Germany, from the manure of the farms of the commune.

Too bad, not seen. It's too late for less than a redif. (?)

I remember when I was a kid in the 50 years, my father was talking about doing that and then it did not happen.
With all the manure produced by breeders, there would be enough to produce a lot of methane and therefore electricity and homes.

The Germans have a head start on us in the ecological approach (see the city of Friborg: everything is solar, even public buildings). They buy solar electricity "photovoltaic" much more expensive than in France which allows private facilities to be profitable quickly enough.

I saw it too it seems to me but it's stupid I do not remember the village where it was installed ...

By cons I remember the figures announced which are:

5 Million of € 1 investment to fuel engine (or gas turbine) of 1000 hp (700 kW) installed in cogeneration (heat 700 homes factué I believe reduced cost) by promoting local manure and green waste.

A small quick calculation of profitability (assuming that the installation is well optimized / dimensioned and runs at 80% of average power 24 / 24):

1) one year electrical production: 700 * 24 * 365 = 6132 Mwhe
we remove 20% for maintenance, ie 4905.6 Mwhe per year produced.

Suppose a green kwhe bought back to say (low estimate) to 10 c €, that is, close to 500 000 € on electricity per year.

2) heat production. Let's take a fuel consumption of 1500L per household per year and a fuel at 0,5 € 700 * 1500 * 0.5 = 525 000 € per year.

Total = 1 Millions of € won or saved per year without taking into account either the fuel price increase or the "cost of CO2".

Following these calculations the installation would be profitable in less than 5 years! Obviously we must subtract the operating costs and raw material supply ... but all the same! When we know that a wind turbine is 15 20 years back, I say bravo.

By cons I do not know if the 5 M € include the establishment of the heat transport network in homes (quite expensive)

A good example of local econology as we would like to see more.

ps: for the cost of CO2, we can make the following estimate:
1) cost of 1 Ton of CO2 = 20 €
2) in Germany 1 kwhe = 0,6 Kg of CO2

Or if you had to pay the cost of preventive pollution CO2 a new economy of: 4 905,6 0,6 * * = 20 59 000 € / year ... this is low but still won 10% of profitability: p

For information, see the village website, Jühnde (near Göttingen)

(click on the document)

From what I understand - but my German is bad-:
the construction of the plant was taken over by institutions (the Federal State, the Saxon State of Süd, the community of Göttingen etc.). The inhabitants paid for the heating: the connection (1000 €) + the opening (500 €) + 4,9 cents per KWh (?). I suppose electricity is resold to the network.

If there are better German speakers ....

In the village next to my home, they are putting the mains drainage with a mandatory financial contribution of 16 000 € per connection (at least for the people I have spoken with).
I would pay for a shared "mega" and take care of my sewage myself (lagunage) than to undergo their stations of purifications mandatory and disempowering.

Hello everybody

A good site for biogas is: http://www.lebiogaz.info/
Who has an idea of ​​the mass of plants it is necessary to methanize to turn a group of 3kW (which corresponds I believe in a domestic consumption "all electric".

Not to mention the tourist benefits (visits of the installation)

Hello everybody

A good site for biogas is: http://www.lebiogaz.info/
.

Thank you, vincent27, for your very interesting link. I read in particular:
With nearly 3.000 on-farm biogas plants in operation, Germany is the leading European country in terms of the number of farms equipped. Result of an ambitious law of development of renewable energy (the EEG - 2000) and purchase prices of electricity 2 3 times higher than those in France, the number of facilities has tripled in less than 5 years. Since 2004, development is accelerating sharply. Main reason? The adoption of even more advantageous tariffs for the breeders. In France, where are we today? Two units are in operation, several projects are under study or in progress, and pricing conditions could be revised in the spring 2006 ...
Is the German model applicable in France? In what conditions ? These visits open up a very concrete reflection.
No comments. Fortunately our German friends are here to give us an example. Long live Europe!

In the navigation bar yahoo there is a translator, well it's not perfect but it helps:

Realization of a biological energy production facility
They think of projecting a clean biological energy production facility, p. ex. a biogas plant or a biomass heating plant and to build? So, an important step for you is to get informed and find confident partners with experiences.
The project Juehnde Biological Energy Village was carried out trusteeship by Ing Hans Erich Tannhaeuser in all business about realization in the function of Projektsteuerers. In common with the operator and the selected specialist the project could be transposed within the budget framework given the high quality standards.


we further recommend Mr. Tannhaeuser des Tannhaeuser to Northeim engineers. Here you will find his contact data:
