14 CHP Potential in Germany 14 (As of March 31, 2006) economically feasable up to 2020; fiction: no political barriers 17th Mai 2011 Dublin

15 Barriers against CHP Lack of information about chances and technical details (sleeping giant) Communal or industrial CHP in opposition to the strategic objectives of some big electricity companies Very ambitious pay-back criteria in industry (< 3 years) Unstable prospects regarding fuel security and prices Dublin 15 17th Mai 2011

16 Benefits of CHP Saves energy resources Climate protection Saves money in the medium and long run Reducing energy dependency Substitution of energy import expenditures by technical and economical knowledge Creates new jobs Higher electric grid stability, higher security of supply Smart and flexible to operate Dublin 16 17th Mai 2011

18 2007 G8 Summit Declaration The G8 Summit Declaration (June 2007) highlights cogeneration in the section on Energy Efficiency. In section 70. Power Generation: … adopt instruments and measures to significantly increase the share of combined heat and power (CHP) in the generation of electricity", Dublin 18 17th Mai 2011

19 The German governments new energy and climate package from August 2007 Dublin 19 Measures Reduction up to 2020 in Mio. t/a CO 2 equ Doubling CHP share in electricity production to 25%20 Reducing electricity consumption by 11 %40 Substitution of old power plants by new ones30 Higher share of RES in electricity production55 Reducing energy consumtion of houses by modernisation of buildings and heating systems 41 Higher share of RES in heating14 Higher efficiency in the traffic and rising share of bio fuels up to 17 % 30 Reduction of non-CO2 gases40 17th Mai 2011

20 New CHP act 2009 Target: doubling CHP share in electricity production to 25% in 2020 Focus on new installations being brought into operation by the end of 2016 Bonus system again; paid finally by the electricity consumers (max. 0,3 Cent/kWh) Bonus on electricity fed into the public grid or directly used > 2 MW elt -> 1,5 ct/kWh over 6 years or max. 30.000h, industry 4 years only 50 kW to 2 MW -> 2,1 ct/kWh over 6 years or max. 30.000h 50 kW -> 5,11 ct/kWh over 10 years Max. 600 Mil /a for CHP plants Max. 150 Mil /a for district heating investments (20% subsidy if at least 50% CHP heat) Monitoring in 2011 Start 1.1.2009 Dublin 20 17th Mai 2011

21 Renewable Electricity Act 2009 Higher Bonus for CHP-electricity (3 ct/kWh) Technology Bonus for innovative CHP technologies Priority for grid-connection of CHP-plants Use of liquid biofuels only if sustainability certificated Practicable conditions for TPA of biomethane 21 17th Mai 2011 21 Dublin

23 Renewable Energy Heat Act 2009 Obligation to use pro-rata renewable energy (e.g. solar panels, pellets) alternatively use of CHP heat ( 50 % produced in CHP ) Obligation for new buildings after 1.1.2009 Legitimization of local district heating obligation by reason of climate protection 23 17th Mai 2011 23 Dublin

24 The governments energy plan Sept. 2010: extension of the operating time of nuclear power plants by an average of 16 years 17th Mai 2011 Dublin 24

25 The governments energy plan After Fukushima: Reviewing the prolongation of the operating time of nuclear power plants Energy turn towards faster growth of renewable energy and higher efficiency 17th Mai 2011 Dublin 25 Nuclear Power Plants in Germany

26 Energy Turnaround: The government new 6-point program 1. Quickly enhance Renewable energy Core of the energy turnaround is the rapid expansion of renewable energies. The wind energy has the biggest potentials. 2. Quickly develop electricity grids and storages...to transport electricity from wind power plants in the north to the south. Expansion of flexible power stations and storage, serving to stabilize the power supply. 3. Consistently increase Energy efficiency By 2020 the heat demand of buildings shall be reduced by 20 percent. Encourage an ambitious renovation. 4. Quickly build flexible power plants In future, flexible power plants must offset the increasingly fluctuating power generation from renewable energy sources. Gas power plants have a special role. The construction of highly efficient and flexible power plants will be promoted in accordance with EU requirements. This is limited to operators whose share of the German power generation capacity is up to five percent. 5. Reorienting Energy Research The funds for research into networking and storage should be increased to 500 million by 2020. 6. Participation of Citizens People should be fully involved to enable a broad dialogue on the necessity of restructuring the energy supply. 17th Mai 2011 Dublin 26

27 27 Perspective RE Development in Germany Trends in electricity generation from renewable energies 1991-2030, based on the Lead Study prepared by the DLR Institute for Technical Thermodynamics

28 The energy future will be decentralised Dublin 28 Tomorrow: distributed/ on-site generation with fully integrated network management (INTELLIGENT GRIDS) Today cleaner, cheaper and more reliable 17th Mai 2011

29 The new role of CHP: flexible electricity production complementary to wind and solar energy 17th Mai 2011 Dublin 29

37 Summary and main results Energy efficiency is a core element of a sustainable energy strategy Conventional heat production in boilers is a big waste of exergy CHP is a core element of an energy efficiency strategy CHP is being discovered more and more by policy makers CHP has a large potential - in Germany and anywhere The Target of doubling CHP in Germany is a big chance for industry and investors We have to make our choice on the future electricity production path – in fact environment tells us that we dont have a choice By using CHP potential and by overcoming barriers against CHP we may learn from each other 17th Mai 2011 Dublin 37
