Rapport final du projet TRACKYLEAKS - Développement d'une méthode d'identification et de quantification des émissions fugitives de biogaz - Application aux installations de méthanisation

Abstract : The French government encourages the development of biogas plants, fulfilling a dual purpose to produce renewable energy and recycle organic residues. This commitment resulted in a reassessment of the price of electricity produced from biogas plants. French government also authorized the Injection of biogas in the natural gas network in 2011. In particular, the agricultural sector is expected to benefit from a strong increase in the coming years. Indeed, a recent Energy Plan (PMAA) carried by the French government schedules a total of 1000 biogas plants in the farms in 2020 whereas only 130 units are present in 2013 . Targeted benefits of anaerobic digestion through this plan are (1) the reduction of methane emissions inherent to conventional manure management, (2) the recycling of organic waste, (3) the contribution to renewable energy (4) the substitution of mineral nitrogen by the digestate. The IPCC estimates biogas leakage between 0 and 10 % (IPCC06), and recommends a default value of 5% in the absence of specific data. According Börjesson and Berglund (2007), these leaks are normally less than 2 %, but can vary between 0.2 % and 13 %. To face this situation on the environmental issue of biogas leakage, data compatible with the life cycle assessment tools are needed, obtained through measurements aiming to identify and quantify the leaks. The ultimate challenge is to prove or move towards an environmental relevance of biogas plants currently and soon implemented in France. The French literature on the subject does not establish specific emission factors to the national context. The international literature shows a range of values which in extreme cases can compromise the environmental benefits foreseen. The proposed project aims at providing new knowledge on the detection and quantification of biogas leaks. An important part of the project will be devoted to experimental work. A validation of a novel method is expected, based on the analysis of optical flow from infrared video imaging.
