5 Natural Gas Infrastructure in Europe Overview major Transmission lines Source: Eurogas Statistical Report 2015 Workshop Power-to-Hydrogen: key challenges and next steps 5

6 Natural Gas Infrastructure in Europe Key facts selected components Total length (EU 28) about 2,2 Mio. km Transport pipelines approx.: Distribution pipelines approx.: km* km* 150 underground gas storages in EU Mio. Customer in EU 28 Existing, safe, reliable and long living infrastructure it would be sensible to use this asset for the transport and distribution of renewable gases (hydrogen and methane) * Assumption based on Marcogaz Technical Statistics 2013 Source of other numbers: Eurogas Statistical Report 2014, Marcogaz Technical Statistics 2013 Source of picture: DBI Workshop Power-to-Hydrogen: key challenges and next steps 6

7 Preparation of the Roadmap Methodology Infrastructure Elements 1 st Level TSO, DSO, End Use 2 nd Level Grouped Elements (pipes, compressors, sensors, turbines, industrial use ) 3 rd Level Evaluation of Grouped Elements H 2 -tolerance (e.g. regarding the materials used corrosion, permeation ) Effect on operation (e.g. grid capacity, integrity management, burning behavior, energy output) Workshop Power-to-Hydrogen: key challenges and next steps 7

8 Preparation of the Roadmap Methodology The identified activities (e.g. SoA-Analysis, definitions of requirements testing ) have been evaluated including timelines, prioritisation and urgency and Considering different hydrogen concentrations (2, 5 and 10 vol.-%) Priority/Impact (1=high/show stopper, 3= low) Urgency start immedeatly, medium term (within 5 years), later time needed (short=5, medium =5-10, long term>10 years) High priority for safety aspects and bottlenecks Result is a condensed list of topics and activities Workshop Power-to-Hydrogen: key challenges and next steps 8

9 ROADMAP AND ACTIONS

10 Roadmap High priority topics Summary of identified actions for x vol.-% H 2 in the gas grid 2 vol.-% H2 5 vol.-% H2 10 vol.-% H2 Gas turbines (e.g. performance/durability/legal iss.) Underground storages (porous) (e.g. bacteria growth) Gas as feedstock (e.g. effect on processes regarding performance, efficiency) Same as for 2 vol.-% H2 plus: CNG on board tanks Fatigue induced failure /vehicle regulation and standardisation Same as for 2 and 5vol.-% H2 plus: Compressors (e.g. performance) Underground storages (caverns) Installations and bacteria growth in underground cavern storages Safety and grid integrity Industrial/residential burners and engines (e.g. performance) The activities identified have different priorities but due to their different duration the should start very soon in order to accelerate and support the energy transition process Workshop Power-to-Hydrogen: key challenges and next steps 10

11 Roadmap Gas infrastructure Workshop Power-to-Hydrogen: key challenges and next steps 11

12 Roadmap End use/appliances Workshop Power-to-Hydrogen: key challenges and next steps 12

13 REMAINING GAPS

14 Need for detailing/remaining gaps Starting asap with activities needed to enable 2 and 5 vol.-% H2 in Natural Gas (Gas turbines, underground storages, NG as a feedstock) Safety focussing on the gas infrastructure should be a high priority topic that will be addressed soon in cooperation with TF5 and TF 4 End-use appliances should be investigated in more detail due to their high variety and number (suggestion: mirror the outcome with SFG-U) Further developing a pan European understanding of acceptable hydrogen concentration in the Natural Gas Infrastructure Workshop Power-to-Hydrogen: key challenges and next steps 14
