Not very hot the land, especially with the droughts which follow one another, soon we will not have enough to feed humanity.

Methanization competes with livestock, especially this year with the drought? In some comments published on Web-agri, farmers deplore indeed "the use of forage areas to feed the methanizers". Others, moreover, doubt the agronomic value of the digestates. Suffice to say that readers seem rather skeptical about the rise of this technique in France.

Titian : "Tired of hearing about methanization all the time, a new El Dorado against the times ..."

Pascal Hautiere : "In times of drought, is it normal to ensile corn for the methanizers? This plant consumes a lot of CO2, but also large amounts of water! You might as well use this corn for animal feed !! A little common sense, thank you ... "

An investment of 30 million euros to make the Ardennes a biomethane leader

PASCAL REMY Factory New 26 / 04 / 2019

Considered as a pioneering department in the niche of anaerobic digestion with the existence of twelve methanizers and a quarantine in its territory, the Ardennes through an investment of 30 million euros are preparing to move up a gear in this domain.

With the support of the Pact Ardennes 2022, a plan signed between the State and the department to revitalize this territory, local authorities and gas operators (GRDF and GRTGAZ) will gather their forces so that the Ardennes become an experimental territory and pilot in the development of biomethane.

The ambition is to reach 80 methanizers, which requires developing up to 325 kilometers of gas networks over the next few years

The main manager of the natural gas distribution network, GRDF, through its general manager, Edouard Sauvage, has estimated to 30 million euros investments to operate on the Ardennes gas networks to promote the biomethane sector and accelerate penetration renewable gas in the mix of the Ardennes network.

Injecting biomethane into the natural gas network

To accelerate the process, help farmers to invest in anaerobic digestion units, the gas operator intends, with the help of all the stakeholders, to co-build the future networks and help the installation of new methanisation units close to the deposit. mobilizable agricultural.

Until then burned to produce electricity or heat, the gas resulting from the fermentation of agricultural manure would now be directly injected into the natural gas network. This is in any case what is offered to farmers in the Ardennes who could also stabilize their income and diversify their activities.

200 to 400 direct and indirect jobs

Additional pipelines will be connected to future methanisers to allow them to reinject their biogas into natural gas networks operated by GRDF.

This program, planned over three or four years, also includes the installation of countdowns and compressors allowing the gas not consumed to flow up into the larger distribution circuits and therefore to store energy

To launch this program on sectors located on the axis Charleville-Mézières-Sedan, the south of the Ardennes, Thiérache and Pointe des Ardennes, a mixed economy company will be created with the Region, the Caisse des Dépôts and Communications and intermunicipal organizations with starting capital of 5 million euros.

"This is a major, innovative and structuring action for the future of the department. These are 200 to 400 direct and indirect jobs, the maintenance of agricultural activity, the recovery of local waste and the development of circular economy with the use of Bio Natural Gas Vehicles which are at stake, ”announces Alexandre Ducruet, GRDF regional director in the Ardennes.

Make an inventory

Currently, technical and economic rules are not yet defined on aid granted to project promoters. The sector concerned is awaiting the decree on the Right to Injection voted in the EGALIM law.

A call for expressions of interest on anaerobic digestion, launched by the State services, will make it possible to establish contacts with the volunteers. Twenty projects have already been identified. Ten are already likely to be put into service, ie 10% of gas consumption of the Ardennes. The first methanizer that will inject into the Ardennes is even programmed to end 2019.

I may have missed an episode, but in my memories (despite everything recent!) French regulations in terms of anaerobic digestion essentially reserved it for the use of waste or by-products of agriculture or agro-food industry, plus household waste in the broad sense (supermarkets, canteens, .....).

Energy crops (intended to integrate a methanizer as is the case in Germany) were accepted only in small proportions.

There would have been changes?

It seems that yes, September balance 2018: on 500 units nationally, 80% are of agricultural origin https://www.terre-net.fr/actualite-agri ... 41101.html

I looked a little, actually there have been changes, 2016-929 7 / 07 / 2016 Decree applicable to 1 / 01 / 2017:

"Art. D. 543-291.-For the purpose of this section, the following terms mean:
“-“ food crops ”: cereals and other plants rich in starch, sugar, oilseeds, and legumes, usable in human or animal food;
“-“ energy crops ”: crops grown primarily for the purpose of energy production;
"-" main crop "means the cultivation of a parcel that is:
"- be present the longest on an annual cycle;
"- be identifiable between the June 15 and the September 15 on the parcel, in place or by its remains;
"-Is marketed under contract;
"-" intermediate culture "means a crop that is sown and harvested between two main crops;
"-" crop residues ": residues that are directly generated by agriculture. This definition does not include residues from related industries or the processing of agricultural products.

"Art. D. 543-292.-Methanization facilities for non-hazardous waste or raw vegetable material may be supplied by food or energy crops, grown as a main crop, up to a maximum of 15% of the total gross tonnage of inputs. by calendar year.

Waste buried in Kermat (56) will become green energy

From April 9, Lorient Agglomeration launches the work necessary for the recovery of biogas from waste buried in Kermat, in the town of Inzinzac-Lochrist. The first injection into the natural gas network is scheduled for next fall.

A major player in the local energy transition, Lorient Agglomération continues its actions on its territory. From November 2019, the gas emitted by final household waste buried at the non-hazardous waste storage facility (ISDND) at Kermat in Inzinzac-Lochrist will be transformed into renewable energy and injected into the GRDF natural gas network.

The buried waste decomposes and ferments, producing a biogas rich in methane, but also composed of carbon dioxide, nitrogen, oxygen and impurities which make its reuse very difficult. Currently, on the site of Kermat, this gas is drained and burned by flaring which generates emissions of greenhouse gases. However, it is a real source of renewable energy that Lorient Agglomération will be able to exploit now thanks to the technical innovation of the Grenoble start-up Waga Energy (Grand Prix of the fight against the global warming in 2016) and the installation of his Wagabox.

In order to transform waste into a resource, Lorient Agglomération has decided to move towards this industrial unit that offers a powerful solution. It will make it possible to value 90% of biogas captured in bio-methane through two stages: filtration and cryogenic distillation. A renewable 100% gas, produced and consumed locally.

The installation of the Wagabox will not generate any odor nuisance or any additional noise. It will allow Lorient Agglomeration to produce approximately 7 million KWh / year of bio-methane annually, equivalent to 70% of the annual gas consumption of the municipality of Inzinzac-Lochrist and avoid the emission of 1 500 tons of CO² each year (equivalent to 200 return Lorient - Sydney by plane).

This project represents an investment of 3 000 000 euros financed by Lorient Agglomération with the help of ADEME and the Brittany Region. In the long term and for a duration of 15 years, the sale of bio-methane will generate for the community revenues estimated at 700 000 euros per year plus an annual valuation premium of 50 000 euros.

I was also surprised by this sentence.There is at least one installation in the West, I do not remember where, where the methane is separated and then liquefied to be transported by tank and be regasified and then injected into the network, but it was linked to an "economic impossibility" of connecting to the gas network.

But on Lorient, it surprises me a little ...

I do not have the answer, but knowing the feed-in tariffs for biogas and natural gas resale and deducting the share of aid, we must be able to know if it is viable in the long term. ..

Of course, in the equation, it is certainly not expected that the fossil energy to run all this (liquid nitrogen and other energy annexes), will become overpriced, see disappear : Mrgreen: : Cry:
The commissioning of a Wagabox takes place within the framework of a tripartite contract involving Waga Energy, a waste manager and an energy specialist. Waga Energy buys the biogas from the waste manager and sells the biomethane to the energy company, at a price that will eventually be comparable to that of natural gas of fossil origin. https://www.bioenergie-promotion.fr/486 ... yogenique/

And since this bio methane is 80% agricultural, with a lot of synthetic fertilizers, we are not going towards more soil erosion and less food for humans, when they need more organic matter to be restored. ?

80% agricultural means that 80% are fed from agriculture in the broad sense, the remaining 20% being either biogas from garbage dumps or sewage treatment plants.

As long as we remain in an economic scheme of the "effluent treatment" type, manure, slurry, various waste from the agro-food industry, crop residues, .., which is now more or less the case in France, that does not pose a problem from my point of view. It "costs" money to the community overall, but it is the price to pay to eliminate / enhance our waste. There is no more synthetic fertilizer used, to answer your question.

It actually becomes very different as soon as we start to grow plants (including the German "model" corn) to put it in the oven directly after grinding in methanizers .... There we are no longer in a "treatment" scheme effluents ".

It should be noted that Germany has almost eliminated electricity purchase rates for new biogas projects, which is a sign that they have certainly gone too far.
