Through the Green Pig project, a pig farmer from Côtes-d’Armor intends to produce green hydrogen for electric mobility from the urine released by his 360 sows.
Launched in October 2018, the program is about to enter a new phase during which a livestock building will be built near a wind farm. The latter will provide electricity to power an electrolyser responsible for producing hydrogen.
According to an article published in West France this Wednesday, January 20, 2021, the urine will be demineralized by filtration through a membrane before being injected into the installation. The residue will then be transformed into a fertilizer rich in ammonium sulphate.
Twenty liters of this liquid are needed to obtain one kilogram of hydrogen. For 9 euros, it would make it possible to travel a hundred kilometers with an electric Renault Kangoo with H2 battery.
By 2024, when the system will have reached the expected operating level, 600 kg of this gas would be obtained daily.
In addition to sustaining employment in rural areas and pursuing sustainable production that is virtuous for the environment and animals, the Green Pig project is timely to support the Brittany region’s program for the development of green hydrogen. and its use in mobility.
Of the 7 million euros in funding that the farmer intends to raise, more than half will be devoted to hydrogen installations alone.
Even if the Green Pig project may make you smile, it is very serious and once again illustrates the various avenues pursued by farmers in order to make their production tool profitable and make it more virtuous for the environment and public health.
But beware, in Brittany, energy innovation issue, nothing is won in advance. There is a great deal of resistance when it comes to installing wind farms or tidal turbines, methanizers to produce CNG, or solar farms. So much so that some elected officials sometimes prefer not to make too many public links between projects for converting public or private fleets of vehicles to new energies and the installations that will supply them with enough power.
With a new pig farm, a wind farm, an electrolyser, and trucks to regularly collect hydrogen, the project will appear very interesting to us, but it will inevitably disturb many people locally.
In any event, such a circular economy approach with waste recovery is of course my support.
