6 6 Energy context in France

7 Current situation in France Electricity production Nuclear MW Installed power in ,5 GW Fossil power plant MW Hydraulic MW Wind turbine MW Photovoltaic MW Other RE sources MW Electric production in TWh 29% of RE energy (Installed Power) Only 135 kg CO2/MWh against 346kg at EU level 1 Hydraulic 11,8% Fossil power plant 8,8 % Wind turbine 2,8% Photovoltaic 0,7% Other RE sources 1,1 % 16,5% of RE energy (production) 1 : EDF source Reference : ( Connaissancedesenergies.org ) Nuclear 74,8% 7

8 Some key numbers of storage capacity Annual consumption (TWh) Storage capacity (TWh) Daily storage capacity (TWh) 490 Electricity Gas Oil products 8

9 Scenario of the energy transition in France 9

10 Dvt of intermittent RE Median ADEME scenario MTEP Perspectives (up to 2050) Primary energy ADEME scenario 50% nuclear MTEP 31% Int. RE In 2050 (MEDIAN Scenario) Renewables Oil Natural gas Nuclear Coal ADEME scenario 18% nuclear MTEP 49% Int. RE Electricity Nuclear : 25% of electricity production Intermittent renewable energies 45% 10

11 Issues of intermittent RE Example : typical energy consumption in France No RE 20% of RE 60% of RE Wind energy Solar energy 2 main issues On a representative week (France) Mismatch between production and consumption => Surplus of production But at anytime Congestion (up to several hundreads of km) Above a thresold of intermittent renewable energies Need of high storage capacity Need of transport infrastruture 11

12 Congestion issue Energy transport cost 2,3M /km 2,17M /km Gas transport is cheaper for energy transportation Approximately 20 times!! 12

13 Storage issue Energy storage capacity Power to Gas with injection into the gas grid is the best (& only) solution for high capacity of storage (>1 day) 13

14 Potential market of Power to Gas in France (2 studies) Study ordered by Made in Made by Potential market of Power to GRTgaz 2013 Not evaluated 25 TW nergetique/documents/hydrogene_et_reseau_ e-cube_grtgaz.pdf ADEME, GRTgaz, GrDF 2014 Between 2,6 and 3 TWh Depends of scenarios Between and 73 T Depends scenari s/documents/fr/power-to-gas-etude-ademe- GRTgaz-GrDF-complete.pdf 14

15 Potential market of Power to Gas (2030) Weekly production surplus and shortfalls for 2030 (ADEME - Median) 31 % of intermittent Renewable energies Annual consumption : 409TWh Suplus :15 TWh Shortfalls : 24,4 TWh Power to Gas : between 2,6 and 3 TWh

16 Potential market of Power to Gas (2050) Weekly production surplus and shortfalls for 2050 (ADEME - Median) 45 % of intermittent Renewable energies Annual consumption : 414TWh Surplus : 44,5 TWh (40-91) Shortfalls : 23,8 TWh Power to Gas : between 20 and 73 TWh (3 scenarios)

17 Potential market of Power to Gas Electricity surpluses could reach ~ up to 91 TWh/year by 2050 in France (based on ADEME Vision 2050) equivalent of 15-20% of French current electricity production. Frequent surpluses over consecutive days (~ 36 TWh > 2 consecutive days) 17 The impact of intermittent energy production is expected to be strong in France by 2050

18 Techno-economic of Power to gas Same price of renewable and fossil methane if carbon tax at /t CapEx & OpEx have to be reduced => need to develop efficient technologies => Need to assess performances on a demonstration project 18

19 Towards a future development of Power to Gas 19

20 Power to gas => H 2 injection H 2 O O 2 Power Electrolyser H 2 Injection in the gas grid H 2 Energy yield : from 70 to 80% 20

21 Power to gas => SNG injection H 2 O O 2 H 2 O Power Electrolyser H 2 Méthanation CH 4 Injection in the gas grid CH 4 CO 2 CH4 Energy density (vol) 3 times higher (36.1 MJ/Nm 3 ) than H2 (10.8 MJ/Nm 3 ) Energy yield : from 50 to 60% 21

22 Power to Gas roadmap in France Hypotheses : 10 MW installations running 2500 h / year 25 TWh Elec conversion Pessimistic or realistic scenario 2,5 TWh Elec conversion 100 Power to Gas plants 1000 Power to Gas plants Or 100 plants of 100 MW. Or a mix 1 demonstrator plant And all can be achieved with existing pipes! 22

23 GRTgaz wants to be positionned as an actor in the Energy Transition As a support of the electrical network Give a value to the electrical surpluses due to renewable production devices Help Power grid reliability and congestion management To contribute to decarbonize gas networks with renewable gas injection H2 or synthetic methane CO2 capture and valorisation for the synthetic methane production To increase energy independancy for the country Local gas production Employment 23

24 To validate studies => Demonstration plant 24

25 Demonstration project => Build a first pilot plant to test the hydrogen and Synthetic Methane injection into the national gas grid The ambition Prepare the Power-to-Gas industry by implementing and demonstrating at the industrial scale an Hydrogen and SNG production plant with: - 2 Electrolysers : a PEM and an alkaline; - a CO2 capture unit - a methanation unit. 25

26 Demonstration project Size of the demonstration : 1MW el plant Methanation 0,5 MW el An integrated project on the complete hydrogen value chain H 2 Electrolyser 0,5 MW PEM H 2 CH 4 Methanation Injection in the National gas grid CH 4 Electricity Electrolyser 0,5 MW Alkaline CO 2 Capture CO 2 or H 2 +CH 4 26

27 Partnership Coordinator : Partners : Strong involvment of industrials + 1 RTO 27

28 Objectives of the demonstration To validate the process as an efficient storage device To validate the available services for the electrical grid (modulation...) To validate technologies Help to launch the Power-To-Gas industry in France To build easy conditions for an industry able to export its technologies To build a Business Model To treat hard topics, one by one, up to reach cost effectiveness The best mean to convince is to go from concept to a real unit 28

31 Location of the demonstration project Planned at Fos sur Mer Harbour nearby Marseille Start of the project In fall 2015 Injection into the gas grid

32 Conclusion To conclude, the Gas infrastructure is an essential component of a global sustainable energy system

33 An European challenge A collaboration topic 33

34 To implement these solutions GRTgaz is working with European transmission companies A shared vision The capacities of existing gas networks, together with the way in which gas and renewable energies complement each other, will help reduce CO 2 emissions by 75% by 2050 compared with 2010 levels (Factor 4). A shared conviction Gas power systems: guarantee supplies at prices that all consumers (individuals, local authorities, manufacturers) can afford, help the development of renewable energies and the low-carbon economy. Areas of cooperation Injection of renewable gas and development of green certificates. P2G technology, e-gas. NGV and LNG fuel for road and maritime transport 34
