2 Agenda renewable energy in Europe and Germany renewable energy from biomass in Germany solid biomass plants in Germany conclusion 2

3 political aims renewable in general and biomass specific Directive 2009/28/EC: promotion of the use of renewable energies entered into force 2009 determine the binding aims cover 20% of the finale energy consumption of the entire EU (2020) share of the biofuels for transportation 10% (2020) various national aims (depending from starting point 2005) sustainable requirements for production of biomass for energy applications only for biofuel and liquid bioenergy sources at the moment 35% reduction of GHG in comparison to conventionally use 50% from and 60% from for solid biomass planned, sustainability standards and certification are most likely 3

5 political aims renewable in general and biomass specific aims in Germany till 2020: increase renewable energy (RE) share up to 18% decrease 10 % of the GHG from transportation by use of biofuels increase heat provision from RE up to 14% increase electric power provision from RE up to 35% increase the biogas/biomethane to approx. 6% from the natural gas consumption (till 2020 ~6 bil. m³; today approx. 300 mil. m³) binding targets! (regulated in nreap) Renewable Energy Act (EEG) is the most important instrument 5

6 Policy instruments for promoting RES - focus biomass Germany Renewable energy sources for electricity (RES-E) Renewable Energies Act (EEG) 2000 Renewable energy sources for heating (RES-H) Market incentive programme (MAP) 1999 Renewable Energies Heat Act (EEWärmeG) 2009 Renewable energy sources for fuels (RES-F) Federal Immission Control Act (BImSchG) - Definition of a biofuel quota (6.25% energetic until 2014) - From 2015 this quota will be replaced by a GHG-mitigation quota (7% until 2020) Energy Tax Act (EnergieStG) - Tax exemption and relief for biofuels 6

22 conclusion solid fuels from biomass Renewable Energy Act (EEG) is the most important instrument the energetic use of woody biomass is enlarged by the EEG steering incentives of the EEG bonus renewable raw material: increasing use of residual forest wood and landscape cultivation materials, but straw and hay seldom used CHP: high rate of heat extraction (only 5% without), essential by new plants technology bonus: increasing use of new technologies like ORC and gasifier (up to 3 MW el ), but low incentives for development of new technologies or improvement of known technologies sustainable standards for biofuels and liquid bioenergy sources are already required sustainable standards for solid biofuels discussed, but so far not details known 22
