1 OFAEnR Conférence sur le rôle du biométhane dans la transition énergétique en France et en Allemagne MEDDE, la Défense 26 février 2015 Frédéric PIERRE Lyonnaise des Eaux

2 Overview 1 Origins of the project 2 Partnership project context 3 Project energy context 4 Innovative aspects of the project 5 Industrial project 6 Uses of biomethane

3 Origins of the project A project driven by Lyonnaise des Eaux et Degrémont Services 2009/2010 : Définition of the study program in response to the call for tenders for the operation of Strasbourg s WWTP 2011 : Achievement of biogas purification and biomethane injection feasibility studies 2012 : Obtaining financial support from EU 2013 : Technology selection, creation of a joint-venture dedicated to the project

4 Partnership project context partners with converging stakes and interests Réseau GDS Réseau GDS wants to develop a biomethane injection route on its distribution network to : Support the development of natural gas in energy efficient solutions and environmentally friendly Contribute to the value production by the provision of a 100% green gas, biomethane, in circular economy logic

5 Partnership project context partners with converging stakes and interests Lyonnaise des Eaux / Degrémont Services Contribute to the optimization of Strasbourg's WWTP's energy model Develop its scientific and technical expertise Contribute to make the Suez Environnement subsidiaries unavoidable in these new professions

6 Partnership project context L Eurométropole de Strasbourg : a proactive Community for Sustainable Development Validation of the WWTP's operator's study program An ambition : to become the Community with the most "green" natural gas in France Validation of a "business model" guarantor of neutrality with the contract to operate the WWTP The availability of an industrial site of national importance

7 Partnership project context Wastewater Treatment Plant of Strasbourg-La Wantzenau 96% of domestic and industrial wastewater from Eurométropole 1 million population equivalent 4 th french plant Average wastewater s daily flow of m m 3 of biogas/year

8 Project energy context GWh WWTP energy balance Current situation 2 GWh Electricity 11 GWh CHP Digestion 5 GWh 6 GWh Furnace HE + flue gas treatment Atmospheric emissions Centrifugation DM 24% Sludge Heat Biogas/Biomethane Flue gas Electricity

9 Project energy context Maintain plant s auto-thermicity Target energy balance Produce and inject 16 GWhLHV/year of biomethane Means to achieve Reduce internal biogas consumption (furnace) Increase biogas production Implement a biogas upgrading unit

10 Project energy context GWh WWTP energy balance Future situation Biogénère 16 GWh Biomethane 18 GWh 1 GWh 0,3 GWh Electricity Digestion CHP Bucher press 5 GWh 1 GWh Furnace HE + flue gas treatment Atmospheric emissions DM > 24% Centrifugation Sludge Heat Biogas/Biomethane Flue gas Electricity

11 Innovative aspects of the project Innovation in terms Regulatory : participation in the development of the french regulatory framework, anticipation of the european normative developments Partnership : creation of a dedicated JV and a legal structure protecting the interests of the Parties and ensuring the sustainability of the industrial project Energy : 1 st french WWTP injecting biomethane, 1,6 MNm 3 /an equivalent to 5,000 low-energy housing or 1,500 biongv vehicles

12 Innovative aspects of the project Innovation in terms Valorisation of biogas components : study of the valorisation of coproduced bioco 2 Chemical and microbiological characterization of biomethane : definition of sampling and analysis protocols, detailed characterization Health : development of a health risk study related to the use of biomethane validated by a Scientific Council Environment : contribution to the reduction of 2/3 of GHG emissions of the WWTP

13 Industrial project Objective : conversion of biogas into biométhane BIOGAS BIOMETHANE 310 Nm 3 /h 186 Nm 3 /h 62% CH 4 > 97% CH 4 50 mg/nm3 VOC < 1 mg/nm3 VOC 400 mg/nm3 H 2 S < 1 mg/nm3 H 2 S

14 Le Projet Industriel

15 Uses of biométhane Objective : to contribute to energy independence of the territory Principle of local use validated by the partners and the Community BIOGENERE requires natural gas suppliers to undertake : - To sell all of Guarantees of Origin in the territory of the Eurométropole, provided that there are viable opportunities, - To provide an annual statement recounting the sale of Guarantees of Origin.
