1 Best Practice Examples Promotion of Cogeneration in Europe and other Countries Variety of Cogeneration Use Slide 52

2 Use of Cogeneration in Industry in Germany March 2010, Prof. Dr. Georg Erdmann Dipl.-Wirtsch.-Ing. Lars Dittmar, Technologische und energiepolitische Bewertung der Perspektiven von Kraft-Wärme-Kopplung in Deutschland Slide 53

3 Use of Cogeneration in Asia Cogeneration has made good progress in S-E Asia during the last 5-10 years Energy generation plants fuelled by natural gas Strong agriculture base with large quantities of residues from agro-processing industries (e.g. sugar and palm oil industries) Malaysia (target 5 % of country s power supply from renewable sources) Uses palm oil for cogeneration In large industrial complexes (e.g. airport, city centres) co- and/or trigeneration is done from natural gas Thailand (cogeneration is about 8 % of total installed capacity) Agriculture industry provides huge potential for biomass cogeneration from rice husk Indonesia (power production 5 % of total power production ) Pulp and paper mills, chemical and textile industries are the largest users of cogeneration Singapore (cogeneration is about 10 % of the total installed capacity) Cogeneration progresses with development of petrochemical and chemical industries Slide 54

4 Docent Katholieke Hogeschool, Greenhouse-Complex, (Kempen, Belgium) Success Factors Gas and electricity prices, combined with the Belgian certificate prices, will enable the CHP plant to run profitably for 5,500 h/a Main Barriers Rolls Royce engine runs on gas pressure of 4.5 bar; however, the Belgian regulation only permits 0.5 bar at a greenhouse site. Installation of expensive booster to increase the pressure Electrical grid connection took time and a lot of communication Slide 55

5 National Museum of Liverpool (Liverpool, UK) Success Factors More than 596,000 /a guaranteed savings (Public Private Partnership agreement, Ener-G would assume the financial/technical/operational risk ) Efficiency of nearly 80% compared to less than 40% for individual heat or electricity generation Biodiesel fueling Absorption chillers to produce chilled water for air conditioning Main Barriers Located on a UNESCO World Heritage site Waterfront position and historic buildings surrounding the museum isolate it from gas and electricity mains Slide 56

6 Hypo Alpe Adria Trigeneration Plant (Tavagnacco, Italy) Success Factors Plant can operate unmanned: remote control through Internet allows the operating parameters to be monitored and modified in real time Main Barriers Many laws and regulations in force in Italy The nation is emerging from a long period in which electricity was a nationalized good. New power plants can therefore supply electricity to several users, either adjoining or in different regions, but they have difficulties complying with the various regulations Slide 57

7 UIPSA Cogeneration Plant in Paper Industry (Barcelona, Spain) Success Factors Replacement of CHP plant (7 MW) at the end of its life Using the latest high efficiency technologies Main Barriers Electrical grid connection Slide 58

8 Micro-CHP Units in Aegean and Egnatia Hotels (Thessaloniki, Greece) Success Factors Legislation on renewable energy sources in Greece is becoming mature State support was crucial to the viability of the project Main Barriers Bureaucracy main obstacle for such investments in Greece, considerable amount of time is needed to deal with it Price of natural gas (as per year 2006), which affects the profitability of the investment, depends on the supplier s tariff policy Slide 59

9 Combined Heat and Power Plant at Jurys Hotel and Towers (Dublin, Ireland) Annual savings and Payback Period 1,200 t of CO 2 Cost savings of 64,000 Payback Period about 3 years incl. governmental funds Fuel: Diesel Fuel Input: 999 kw Engine type: Dorman 6DTg Electrical output: 304 kw (30%) Thermal output: 445 kw (45%) Slide 60

10 Combined Heat and Power Plant at Kings College Hospital (London, UK) Annual savings 2,555 t of CO 2 (approximately 25% site carbon emissions) Cost savings of 537,000. Fuel: Natural Gas Electrical output: 1.8 MW e MW e (total 4.2 MW e ) Boiler: Chillers: one 10 t/h and two combination fired/exhaust gas waste heat boiler two 1,250 kw e absorption chillers Slide 61

11 Cogeneration Plant at Phu Khieo Bio-Energy Co. Ltd., Thailand Owner: Phu Khieo Bio-Energy Co., Ltd. (PKB) Major shareholders: United Farmers & Industry Co., Ltd., others Fuel: Major offtakers: Electrical output: Boiler: Sugar cane bagasse, cane leaves, wood bark and rice husk Electricity Generating Authority of Thailand (21 years contract), United Farmer & Industry Co., Ltd. (steam + power) 41 MW e (extraction condensing steam turbine, Alstom) 2 x 120 t/h, 68 bar, 510 C (Alstom) Existing equipment: Boilers + turbine (from sugar mill) O&M: Internal Slide 62

12 District Heating with Sintering Plant Waste Heat (Pohang, South Korea) Research Institute of Industrial Science &Technology Pohang s Center for Science and Technology Housing complex Slide 63

13 Cogen for Africa Project of Energy, Environment and Development Network for Africa (AFREPREN) Cogen for Africa ( Supported by the Global Environment Facility (GEF) via the United Nations Environment Programme (UNEP) and the African Development Bank (AfDB) The overall objective of the Cogen for Africa project is to help transform the cogeneration industry in Eastern and Southern Africa into a profitable cogeneration market. Slide 64

14 Cogeneration Investment at James Finlay Tea, Kenya Turbo Generator Wood chip preparation Fuel: Electrical capacity installed: Thermal capacity installed: Planned expansion: Wood chips 800 kw 11 MW up to 2.7 MW e and 37.1 MW th Wood chip preparation area Slide 65

15 Cogeneration Investment at Kakira Sugar, Uganda Fuel: Electrical capacity installed: Thermal capacity installed: Planned expansion: Bagasse (from sugar cane) 16 MW 100 t/h 30 MW e and 60 MW th Slide 66

16 Biomass Cogeneration Project in Azerbaijan Renewable Energy Development Project in Azerbaijan Project supported by the Asian Development Bank (ADB) Slide 67

17 Ideas for Innovative new Cogeneration Concepts: Stadtwerke Rosenheim Plant Regarding the given accelerating growth of renewable energy sources such as wind and solar power in Germany, it is essential to create a more flexible energy supply infrastructure. VGB PowerTech, 11/2013 Annual energy production from wind and solar in Germany sums up to 13,1 % (2013). Total production from renewables is 23,9 %. Slide 68
