1 Developments and outlooks for biogas in Denmark Danish-German Bioenergy: Technologies, Opportunities and Outlook March 15, 2016

2 Agenda Brief overlook history and status Targets for biogas development in Denmark Biomass availability feedstock management Applications upgrading and injection Feasibility framework conditions Challenges and perspectives

3 A brief look in the rear view mirror Late 80 es mid 90 es Centralized biogas plants established Farm Scale Biogas Plant concepts developed, only a few established Several large Farmscale Biogas Plants established Many feasibility studies, but Very few plants established 2012 New Energy Agreement in the Danish Parliament

4 STATUS 24 Centralized Biogasplants (CBP) 67 Farmscale biogas plants (FBP) 3,2 mill tons manure tons organic waste < tons energy crops 2015

5 Target Green Growth Plan 50% of manure/slurry to be treated in biogas plants by PJ from biogas (total potential 40 PJ) (app 4-5 PJ in 2015) Biogas production Manure in biogas plants: % Green Growth: 50% in 2020 CBP FBP Total

6 Parliament agreement from 2012 Regulation of the price of biogas CHP Upgrading and injection Process energy Transportation Analysis of the gas infrastructure Biogas Task Force established Monitor and support new projects Elaborate reports on critical issues Monitor progress and suggest improvements

7 Biomass availability Most promising resources Slurry Solid manure Straw Municipal (household) organic waste

8 Feedstock management - challenges Facilities for: Treatment of biomass with high TS- % Separating sand from solid manure and other feedstock Pretreatment of cellulosic feedstock, especially straw Pretreatment of municipal household waste

9 Biogas development in Denmark Available ressources - Existing plants = Sites for new plants Also taken into consideration: Projects in planning Mobility of resources Consumer for the biogas Not taken into consideration: New FBPs may occupy significant ressources

10 Applications Until 2012: FBPs: CHP, heat utilized at the farm ( heat surplus in summer) CBPs: CHP, heat used for district heating After 2012: Upgrading and injection into natural gas grid Still CHP where applicable

12 Challenges and perspectives Methane emissions from biogas plants may compromise sustainability as well as biogas plant feasibility!

13 Methane leakage Leakage detection with FLIR camera Quantification by covering the leakage and measuring the flow and concentration
