  1. biogas in the city skyline Polderwijk Zeewolde Klaas de Jong

  2. Introduction Essent • Essent is a Dutch based utility with a turnover of EUR 7,4 billion and appr.11.000 employees • Essent is largest producer of green electricity and biomethane in The Netherlands • Essent Warmte operates several district heating grids and has more than 70.000 customers

  3. revival for district heating - communities demand CO2 reduction for new residential areas - district heating is flexible: waste, heat, biofuels, heat pumps, CHP green heat

  4. district heating Essent • traditional district heating (heat from power stations and CHP) • since 2000 several projects with heat pumps and seasonal heat storage • in 2007 three projects with biogas CHP in new urban areas with low-energy houses (heat demand 20-30 GJ is 5500-9000 kWh per year) • Techum/Jabikswoude in Leeuwarden • Zuidbroek in Apeldoorn • Polderwijk in Zeewolde highest reduction of CO2 with biogas CHP

  5. Leeuwarden Zeewolde Apeldoorn

  6. Zuidlanden - Leeuwarden • district heating for 750 new low-energy houses, school and care centre • extension with 300 houses expected • dairy cattle farm "Nij Bosma Zathe" of Wageningen University produces biogas • 5,5 km biogas pipeline for transport of biogas to 2 x 340 kW CHP located between the dwellings Techum and Jabikswoude

  7. low-energy houses in Techum

  8. biogas pipeline farm district heating district heating CHP

  9. Zuidbroek - Apeldoorn • district heating for 2500 low-energy houses, schools, shops and care centre • production of sewage gas and biogas from slaughterhouse waste at sewage treatment plant of Waterschap Veluwe • 2,5 km pre-insulated pipe for transport of green heat to Zuidbroek residential area • community of Apeldoorn plans to be energy neutral in 2020; district heating Zuidbroek in project Sorcer of EU Concerto+programme • biofuel peak boiler, hot fill connection for dishwasher and subsidy for individual pv with support of Sorcer

  10. Polderwijk - Zeewolde • district heating for 3000 new houses • dairy cattle farm produces biogas • 6 km biogas pipe line for transport of biogas to 1 MW CHP in Polderwijk boiler house • 50% reduction of CO2 for heating and electricity consumption compared to standard for new houses

  11. biogas CHP 3000 houses Polderwijk Zeewolde Groene warmte uit biogas van melkveehouderij

  12. Why biogas for district heating? • biogas can easily be transported to residential areas • heat of biogas engine fulfills demand for legionella safe heat supply to houses (temperate 70 degrees for domestic hot-water) • green heat is effective tool in development of climate neutral cities

  13. Essent: more biogas in the city • Essent Warmte is offering district heating based on biogas for several new residential areas to communities in The Netherlands • Essent Warmte is investigating supply of biogas to CHP in existing district heating projects • Essent Warmte actively promotes maximal utilisation of biofuels and is member of Dutch association for biochp www.biowkk.nl

  14. heating without global warming the future is to biogas chp klaas.de.jong@essent.nl design of energy station Zuidlanden Leeuwarden
