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

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

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

15
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
