1 Power-to-Gas: A Promising Solution to Integrate Large Quantities of Fluctuating Renewable Power European Utility Week Amsterdam, 16 October 2013 Gerbert van der Weijde E.ON Innovation Center Energy Storage

2 Power-to-Gas: A Promising Solution to Integrate Large Quantities of Fluctuating Renewable Power Storage of fluctuating renewable power in the existing natural gas grid: context and aims Experiences made during set-up and operation of the E.ON power-to-gas pilot plant Falkenhagen Exploring the business models for power-to-gas 2

3 Context for energy storage Intermittent generation wind power, solar power Fluctuating demand households, industry Problem Sometimes generation deficit Sometimes grid congestion / excess generation = Curtailment of RES & Conventional Generation Energy storage delivers flexibility in power system

4 Increasing demand for flexibility 4

5 Various sources of flexibility Sources of operational flexibility Generation Coal Gas Nuclear Renewables Grid extension Storage Demand management Supply-side Demand-side E.ON Innovation Center Energy Storage

6 Energy storage technologies Proven Technology - Potential for improvement - New Technology Availability, Specification, Cost Effectiveness, Acceptance, Dimension Battery Capacitor Pumped Storage P. (A) CAES Power to Gas to Grid or to Caverns or to Power Heat Fly wheel 6

Power-to-Gas is the only service offering long term and very large scale storage although it can act on short term as well.

8 Overview of E.ON s power-to-gas activities Technology Power-to-gas demonstrator Falkenhagen (2MW Alkali; COD: Aug 2013) Power-to-gas demonstrator Reitbrook (1MW PEM; COD: 2014) Supplier analysis Business Partnership with Swissgas (Oct. 2013) E.ON Windgas end-customer product (Oct. 2013) Studies Various studies into potential of power-to-gas technology in various business models 8

9 Example: E.ON Power to Gas -Pilot Falkenhagen Key Parameters Power: 2 MW el Hydrogen production: 360 m³/h Fed into the local gas grid (ONTRAS) Start of operation August 2013 Owner is E.ON Gas Storage pipeline connection Low voltage supply Control Goals Power supply Gain experience in technology, costs, consenting, etc. Demonstration of the process chain Optimize operational concept Metering Electrolysis

10 Site Falkenhagen 4 km Falkenhagen: Wind power generation Power and Gas infrastructure E.ON edis operation 10

11 Building the plant Groundbreaking ceremony on the 16 October 2012 Construction started 20 August 2012 Groundbreaking 16 October 2012

12 Operating the plant Commissioning ceremony: 28 August

13 Experiences during set-up & operation of Falkenhagen Gain experience in technology, costs, consenting, etc. Specification & procurement of electrolysers Steering the installation Actual performance of the installation Connecting & feeding in to the gas grid Certification process ( biogas ) Public perception Etc. Demonstration of the process chain Learning by doing Trigger for discussion Optimize operational concept Work in progress... (different operational regimes, etc.) 13

14 Power-to-gas: convergence of power and gas grid Power Grid Electrolysis H 2 CH 4,Bio CO 2 SNG Natural gas grid Power Heating Mobility Industry Power Heating Mobility Industry Natural & renewable gas Renewable hydrogen

15 What drives power-to-gas forward? Drivers Increasing need to integrate renewable energy Increasing need for low-carbon & low-iluc renewable gas & fuel Opportunities PtG integrates renewable power into different market segments. PtG offers a solution for sustainable mobility. PtG is an alternative source for gas with lower carbon footprint also compared to biogas and biofuels. The gas infrastructure renders large capacities for transport and storage.
