Renewable Gas The Potential of Biomethane

Transcription

1 Renewable Gas The Potential of Biomethane Gas Natural Fenosa Foundation Workshop 26th October 2017; Barcelona Jan Stambasky President, European Biogas Association

2 EBA Represents over 7,100 Stakeholders

3 Biomethane Industry Including Anaerobic digestion followed by biogas upgrading Including Gasification of renewable organic matter followed by syngas conversion to biomethane Power-to-Gas technology producing biomethane from biogenic carbon or utilizing biological pathways

4 Biomethane from Anaerobic Digestion Biogas cleaning Removal of trace impurities from the biogas like sulphane, ammonia, siloxanes etc. Removal of water droplets and moisture Biogas upgrading Removal of carbon dioxide Removal of nitrogen in some special cases (landfill gas)

14 Why Biomethane (and not H 2 )? Scientific Advisory Council - SAC Existing infrastructure, feed-in without any restrictions at any time: Pipelines, network, facilities, storage in caverns/aquifers, gas turbines, appliances compatibility 3,5 times higher storage capacity: Hydrogen needs much more space (or pressure ) for the same amount of energy Existing and affordable consumer applications CH 4 is already an universal energy carrier - CNG cars and busses, CNG/LNG trucks, ships, industry Methane is also a raw material! Flexibility: depending on the market situation and the infrastructure, energy can be transferred between different energy carriers.

15 Biomethane Statistics & P2M Capacity 18 bcm Biogas in CHP applications (methane equivalent) 1.7 bcm 80 bcm Annual biomethane production Hydrogen could be methanised with 20 bcm CO TWh Electricity could be methanised only by our industries With the existing production capacity!

16 Efficiency: Heat Losses Not Lost! Scientific Advisory Council - SAC

17 Synergy in Process Integration Scientific Advisory Council - SAC Methanation produces heat, which can be perfectly integrated into the upstream gas production facilities, thus heat is fully utilised Biological P2M process can be integrated even more, and to replace the raw biogas upgrading process (Viessmann) Gasification offers large scale process integration Carbon efficiency dramatically increases in both processes: P2M process integration significantly improves the CO 2 footprint of biomethane, thus enabling greening more natural gas

25 Gas Future: 2 nd Transition is Coming

26 When This Will Start?? It Has Already

27 European Renewable Gas Register - ERGaR Established on 28/09/2016

28 Conclusions I. Scientific Advisory Council - SAC Biomethane industry is a strong and mature partner for green electricity, with considerable production capacities today, and sound potential for the future Power-to-Methane technology has no limits in conventional gas industry and its implementation is cheaper and quicker Power-to-Methane technology and biomethane production are much synergetic, easily integrated, and with tremendous potential in utilization of existing CO 2 streams

29 Conclusions II. Scientific Advisory Council - SAC Biomethane industry is a developed industry, with solid background in AD and gasification and new developments in Power-to-Gasconsiderable production capacities today, and sound potential for the future Biomethane is the right partner providing natural gas industry decarbonisation Energy grids, gas and electro, must be seen as one, as the Integrated Energy Grid System
