Presentation Transcript

  1. The Company: • More than 12 years of experience in designing, planning and construction of biogas power plants. • Input of the first plants: organic waste (fats and flotates); • Weser-Ems region: intensive livestock farming • Biogas-boom since amendment of • the EEG (law on renewable energy) • in 2004 • More than 250 biogas plants built • Installed capacity over 140 MWel

  3. Energy For The Future • Biogas • versatile source of renewable energy: providing electricity and heat • reduction of harmful methane emissions • CO2neutrality • environmentally friendly way of preserving resources

  4. Biogas Flow Diagram

  5. Planning and Project Development • Project • Conception • Quotation • Financing Assistance • Approval planning

  6. Plant Construction • Building phase • bwe installation teams set up the agitators, gas storage roofs and pipelines • Use of low maintenance and energy-efficient agitators • Connection of the high performance CHP units with engines upward of 190 kW

  7. Technology • Biogas plant • User friendly process control systems • Control of individual plant components and documentation of the control • parameters • Remote access to the control system

  8. Natural Gas From Biogas • Biogas Preparation • Often there are no possibilities to use the heat economically • Upgrading of biogas to natural gas quality • Transportation through the existing natural gas network • Alternative use as fuel for vehicles

  9. Heat use • Transportation of heat • Increasing efficiency by utilizing surplus heat • Use of district heating for nearby houses and stables • Wide variety of possible consumers, • e.g. heat for drying plants (cereals or digestate) • Arbitrary choice of temperature level (default at 85 °C)

  10. Micro-Gas Distribution System • Transportation of biogas • the CHP is placed next to the heat consumer • transport of biogas to the CHP unit through a gas pipeline • lower investment required compared to district heating • moreefficient use of thermal energy, no losses during transportation
