1 Challenges in integrating biogas in the existing gas networks Peter Beumers Productmanagement Alliander CEDEC Gas Day 27 mai 2014

2 The Dutch association in the energy sector representing the interests of national and regional electricity and gas network operators in the Netherlands. To facilitate the smooth functioning of the market and to manage the physical infrastructure of the transport network. 2

3 Overview Goals, Ambition Energy Production Energy Distribution Energy Usage/ Application Innovations chain interactions technical, economical, institutional, society Energy Production: Sources & innovations Energy Distribution: View integration of networks demand markt local energy solution Energy Usage&Production: Innovations History City gas, natural gas, regulation 11 June

4 Biogas market Agricultural Sewage Waste Germany 3200 MW

5 Energy Production: Ambition EU: 2030 climate and energy goals: 40% greenhouse reduction target for 2030 Renewables target of at least 27% Initiatives: Biogas, Biomethane, Gassification, Power to gas H2 Made possible through: Dutch subsidy schemes: Goal procent renewable, 3.5 billion Euro s 340 mln Euro Biomethane:60 mln m3 Cost efficient, energyproduction methods competition Farms with 100+ cows

6 Energy Production: Current status & Ambition Distribution Domestic Use : 40 Billion M3 Dutch potential Biogas: 3,7 bln.m3 biogas (75 PJ)+Syngas 2,3 bln (10% total volume) Current status: Biomethane: 120 mln m3, 26 plants biomethane Biogas conversion to Electric: 1000 mln kwh, 200 plants Facilitating this transition, with changing demand structure More biogas & biomethane, less demand, new gassources (LNG)

7 Energy Usage: Towards Nearly Zero-Energy Buildings (NZEB) 2020: Strong reduction Nat gas Households Decarnonisation Local Usage vs. Central Energy Production (investment window yrs) - (investment windows 30 yrs?) Compensation CO2 with local renewable production Low carbon technologies (CO2 reduction /Cost): With gas Condensed Boiler + Photovoltaic Cells Mixed biogas/nat gas boiler + Photovoltaic Cells Gasheatpump + Photovoltaic Cells Condensed Boiler, Solar Boiler + Photovoltaic Cells Gas Fuel Cel + Condensed Boiler (tap water/-20c)+ PV Air Heat Pump + Condensed Boiler +Photovoltaic Cells Low carbon technologies (CO2 reduction /Cost): All electric Air Heatpump+ Electricity boiler +PV Soil Heat pump + Electricity boiler +PV Low carbon technologies (CO2 reduction /Cost): Heat Waste Heat distribution network, Biogas, nat. Gas back-up, PV CHP Heat distribution network, CHP+ PV Economics Economics Economics Regional Choices

8 On-going innovations Production Innovations in pre-treatment: Enzymes, Thermo- mechanic, - Chemical Innovations in Digestion Mono digestion, high pressure digestion, gassification Extraction minerals Innovations in Upgrading Upgrading, cryogenic, quality measurement Innovations in Upgrading Upgrading, cryogenic, quality measurement Distribution Innovations in Distribution Quality measurement: Continuous (sensoric) Two Way distribution (compressor) Mixing stations, for feed in Mixing-back-up stations, for feed in Dedicated Grids (biogas networks) Nat. gas back up grid Biogas to heat Biomethane- hub Electronic Nose Odorant Chip level gasquality Appliances Innovations in Appliances Biogas to heat networks Biogas/Nat gas heating boiler (consumer) Nat- gas back-up solutions Full automatic wide range gas-adaptive burners, gas-adaptive boilers (60-98% methane) Materialchoices 11 June ct/m3 Economy 20 ct/m3

9 Production: New sources Facilitating this transition, with many sources: Mono digestion: Manure all cattle farmers (200 animals) a digester? (3.8 mln Cows, 12mln Pigs, 100 mln Poultry (2013) New Sources: Grasses, Seeweed Gassification

12 Development

13 New Roles/Services for the DSO Becoming an integrated system operator Managing New Services: To safeguard for end-customers Quality of Supply Security of Supply Facilitating Production & Demand through dedicated networks The DSO? Investor in dedicated networks, Match maker? 11 June 2012

14 Biogas & Natural Gas New Tasks related to quality of Supply? Gastreatment Quality Gatekeeper: Stationary monitoring Wobbe Index and Odorant Mixing Biomethane Reporting on-line gasquality, cal. value Last Resort Controller Predict fast quality changes in network Gastreatment - A trustworthy cashregister: - Measurement & Billing: - Calorific Value - Measurement on grid connections

15 Biogas & Natural Gas Safeguarding the Quality of Supply Reliable Distribution System: Accomodating to 100% biomethane in networks Fastresponse Quality Problems: Direct Shut Down Congestion manager: first come, first serve, upstream compression) Stationary monitoring Wobbe Index and Odorant Informing customers Publication distributed gasquality, cal. value Measurement & Billing: Calorific Value

16 Biogas & Natural Gas Safeguarding the security of Supply Congestion management (first come, first serve, upstream compression), pressure management Mixing Biomethane Congestion management (first come, first serve, upstream compression)

17 Safeguarding Security of Supply Facilitating through dedicated networks: Managing Biogas networks Standards: Engineering guidelines: Depth, safety-distances, markation (DVGW G 415) Repair, Maintenance guidelines Guidelines Leakages Public Parties Components: Feed-In Station Gasstation SAFETY STANDARD Natural gas

18 Overview Goals, Ambition Energy Production Energy Distribution Energy Usage/ Application Chain interactions technical, economical, institutional, society Goals and Ambition: What to expect? 1% to locally 100% Biomethane Energy Usage&Production: Who will invest, secure investments & subsidy schemes Energy Distribution: With which kind of network and which business domain: Regulation, Qos, SoS, a new domain Energy Usage/Applications: Flexibility of appliances, QoS, SoS Goal oriented regulation 11 June
