1 Power to Gas within Uniper Dr. Peter Klingenberger, Senior Advisor St. Petersburg,

2 Uniper: reliable energy provider and co-creator of the energy future We are Uniper, an international energy provider with approx. 13,000 employees and activities in more than 40 countries. We are one of the big energy providers in Europe, a most important market worldwide. Our core business is power generation in Europe and Russia, as well as global commodity trading. We are working on sustainable solutions that support the energy transition, and make the socalled Energiewende possible. 2

3 Installed capacity in GW Increase of intermittent renewables in Europe PV Wind PV Wind PV Wind Solar PV reference scenario Wind reference scenario Solar PV Hi-RES scenario Wind Hi-RES scenario Scenarios taken from the study Commercialisation of energy storage in Europe (FCH-JU, 2015) High-RES scenario: > 60% variable renewable energy until 2050 Share of electricity from renewable sources shall increase to 36% until % until 2030 and > 80% until

In Germany a certificate for hydrogen as biogas is already in use. 3 SNG = Synthetic Natural Gas 5

6 Project WindGas Falkenhagen Key Parameters Partner: Power: 2 MW el Hydrogen Production: 360 Nm³/h Technology: Alkaline electrolysis Fed into the gas grid of ONTRAS Goals Demonstration of the process chain Optimization of operational concept (fluctuating wind power/gas feed) Gain experience in technology, costs, permitting, trading 6

7 Technical experience WindGas Falkenhagen 3 years of operation very successful. More than 8 GWh hydrogen ( WindGas ) have been produced from renewable electrical power and injected in the natural gas grid. More than 10,000 operating hours with more than 800 starts and stops. The efficiency is better than expected. No PtG-specific shutdown of the plant have been detected during operation. Degradation was not detectable. Successful prequalification to participate on German secondary balancing market. The technology is ready for the market and has further potential in performance and costs reduction. 7

8 Project WindGas Hamburg Key Parameters Max. Power: 1,5 MW el (stack) Hydrogen production: 290 m 3 /h Fed into the local distribution gas grid Start of operation: 15 th Oct 2015 Public funding from BMVI (ministry of transport) Goals Utilization of high efficient "Proton Exchange Membrane" electrolysis (PEM) Demonstration within Uniper infrastructure Business development Subsidy & Partner: 8

9 Project WindGas Hamburg Breakthrough in stack power density 70 cm 140 cm 49 cm Alkaline electrolysis 1 MW el PEM electrolysis 1,5 MW el Source: Hydrogenics GmbH 9

10 Technical experience WindGas Hamburg Successful upscaling of PEM-technology to MW range The new PEM-Technology is very compact and efficient Because of high pressure (25 bar) of electrolysis, no compressor is necessary for injection of the hydrogen into the natural gas grid The maximum power uptake of the PEM-stack (1,5 MW el ) is 50% higher than initially planned 10

11 Methanation in Falkenhagen Key Parameters Renewable hydrogen: 210 m³/h (from exististing PtG plant) Biogenic CO 2 : 52,5 m³/h (external supply) SNG 1 production: 57 m³/h (catalytic) Injection of SNG into natural gas grid (ONTRAS) Start of operation: December 2017 Goals Testing new methanation technologies Gain experience: technology, operation and permitting Assessment of economic and business aspects and analyze the large-scale storage and market-uptake potential of the technology Horizon 2020 funding (EU) Consortium: 27 partners from 6 European countries 3 locations: Falkenhagen (Germany), Solothurn (Switzerland), Troia (Italy) Duration: 48 months 11

13 Current regulation blocks first commercial applications for Power-to-Gas (i.e. refinery case) DE EU Green hydrogen shall be equally treated as advanced biofuels also the use in refining processes CO 2 reductions caused by use of green hydrogen in refineries are not recognized under current regulation 104,3 fossil H2-91% 9,1 green H2 Emissions g CO2 / MJ DE Sector coupling in order to integrate renewable electricity and to reduce emissions in different sectors Industry Power Gas Mobility Heating Energy DE Energy storage should not be treated as consumer regarding fees and taxes Fees and Taxes Price of energy 13

14 Possible scenario: Green Hydrogen can develop from a niche market to a hydrogen economy Cost efficient start Green Hydrogen for refineries Reduce emissions and provide flexibility to the electricity grid No investments in infrastructure needed Cost reductions for electrolysers (economies of scale) Spill-over to other applications Green Hydrogen for industries Substantial CO 2 reductions Limited infrastructure changes Green Hydrogen mobility H 2 mobility (cars, trains) Alternative to battery vehicles Cost efficient start Green Hydrogen economy Utilization of natural gas infrastructure Re-electrification makes PtG a flexible backup for renewables Development of hydrogen infrastructure (grids and storage) The use of Power-to-Gas in refineries will decrease CAPEX (of electrolysis) and accelerate technology development which can enable deployment in other applications. 14

15 Hydrogen in the Natural Gas Transportation System Technical Solutions to be provided 1. Hydrogen content limited by German and European Standards (e.g. DVGW G 260, G 262) Maximum 10% (town- (coal-) gas standards not longer applicable) Calorific value must not fluctuate significantly thus Hydrogen content must not fluctuate Transport, storage and other facilities must be able to handle Hydrogen without additional measures, thus today Hydrogen not allowed in the high pressure part of the grid 2. Hydrogen content limited by technical requirements for use in mobility Producers of CNG fuel tanks limit Hydrogen content to 2% 3. Injection of local (green) Hydrogen must not be prohibited Imported Hydrogen to stay well under maximum allowable content to allow local green Hydrogen to be injected into the grid 4. Storage facilities In some porous rock storages Hydrogen might cause chemical and biological reactions leading to decreasing Hydrogen content and increasing Methane, CO2 and H2S contents No experience of high hydrogen contents in gasturbines and gascompressors until today 15
