1. Evolution of DHC in The Netherlands Klaas de Jong, June 11 th 2014, Copenhagen

2. We are small but growing up DH covers only 4 % of heating demand Individual gas boilers are standard Consumers do not trust heat bills and lack freedom of choice for supplier

3. DH developed after first oil crisis power stations as heat source 13 large traditional grids dating from 70’s for some 250,000 households

4. The traditional players Utilities selling electricity, natural gas and heat 1.Eneco DH in Utrecht, Rotterdam, The Hague, Leiden, greenhouse area Owned by municipalities and province Heat from power stations E.ON and NUON and own CHP 2.NUON (Vattenfall) DH in Amsterdam, Almere, Arnhem, Lelystad, Nijmegen joint venture with city of Amsterdam 3.Essent (RWE): recently sold to pension funds PGGM and Dalkia new trade name Ennatuurlijk DH in Breda, Tilburg, Eindhoven, Enschede, Zeewolde, Leeuwarden, Zwolle, greenhouse area Plukmade

5. Gas fired cogeneration in problems Electricity market disturbed by new coal fired power stations, import of wind an sun from Germany and high price of natural gas compared to coal NUON builds first large capacity heat storage at Diemen for DH in Amsterdam and Almere Pipeline Diemen-Almere 8.5 km in sea

6. Times are changing New players in the field: municipalities waste-to-energy companies port authorities owners of greenhouses contractors New heat sources: wood chips seasonal storage heat & cold surplus heat industries deep geothermal heat biogas solar heat

7. Waste-to-energy becomes mayor heat supplier Large investments in Amsterdam, Rotterdam, Nijmegen, Dordrecht, Alkmaar, Enschede and Delfzijl (open steam grid operated by Seaports Groningen) Construction of pipeline from AVR to centre of Rotterdam over distance of 17 km: change-over DH from E.ON Power to W-t-E; investment 70 million euro

8. A lot of projects with seasonal storage individual and DHC Amsterdam, terminal cruise ships

9. Deep geothermal growing fast In a few years some ten geothermal wells for clusters of greenhouses Worlds first(?) : methane gas utilised in CHP In Pijnacker near Delft a greenhouse owner supplies heat to schools and houses

10. Warmtenetwerk Innovation Awards Winner professional jury Flexible tube with premounted connections Election public: DH connected tap water heat pump for low temperature grids

11. Biomass Several new DH schemes with wood chis or wood pellets for 200- 2,000 houses Replacement of gas fired cogeneration by biomass boilers and biomass CHP in existing DH (examples Purmerend and Eindhoven, Utrecht in development) Music Quarter Zwolle with wood pellet boilers Pilot: real time monitoring water quality Music Quarter Zwolle with wood pellet boilers Pilot: real time monitoring water quality

12. Dutch industries manufacturers of flexible pipe systems, DC pipes, substations, peak boilers, wood fired boilers, heat pumps, meters, residential adsorption chillers, heat exchangers, water treatment equipment contractors; expertise in horizontal drilling and water crossings consulting engineers GEA Grenco heat pumps for Copenhagen Towers HeatMatrix plastic exchanger for flue gas Solabcool 5 kW adsorption chiller

13. It’s time for district heating Groningen gas field within a few years not enough for Dutch demand Production will also decline because of danger of earth quakes

14. European natural gas capital goes for DH on deep geothermal Joint venture of city of Groningen and water utility for DH Subsidy of 33 million euro available for 15 years of heat production from a geothermal well at 3 kilometers Headquarters of Dutch Gasunie Original main office of Groningen University
