Question 45224 — energy and fuels

Summary

Mr. Gaël Le Bohec draws the attention of the Minister of Ecological Transition to the need for a relaxation of the self-consumption obligation for agricultural methanization. Agricultural methanization is the process which makes it possible to produce biogas, which is mainly made up of methane (CH4) and which can be transformed into electricity or heat, or be injected into the natural gas network: we then speak of “ biomethane” or “green gas”. However, to produce this biogas, which constitutes a renewable and carbon-free energy, the regulations are very strict and only allow it to be obtained by the degradation of organic matter by bacteria in an oxygen-free environment. In fact, biogas is produced in a closed environment: in a tank called a digester, the temperature of which must be maintained at 40° C. In a conventional installation, part of the The produced biomethane is used to heat the digester. This intra-consumption represents 4 to 5% of the methanizer's production, which is therefore burned on site. The energy sources authorized to heat the digester are strictly defined within the decree of November 23, 2020 repealing the decree of November 23, 2011. While the first decree of 2011 admitted in addition to this self-consumption the use of heat fatal from pre-existing equipment installed on site or on a site located in the immediate vicinity for all methane digesters, the 2020 decree imposed new restrictions. It makes a distinction between methanizers based on wastewater treatment plants and agricultural methanizers: from now on, only methanizers based on the treatment of urban wastewater can use the waste heat from equipment. installed on site. This unfair treatment imposed on agricultural methanizers is all the more incomprehensible given that the production of biogas is encouraged to improve France's energy autonomy. Modifying this regulation would thus make it possible to increase the quantity of gas injected into the networks, without modifying existing installations. He therefore asks it to align the regulations relating to methanization agricultural on that applicable to urban methanization.
