Advancements and applications of UTES in DHC networks

IF Technology is a geothermal energy company in engineering and consultancy Leadership in the sector in the Netherlands: from conceptual phase to operational phase Projects in the Netherlands, Belgium, Denmark, Spain, Canada, Norway, UK and USA Employing 95 geologists, hydrogeologists, civil-, energy/mechanical- and well engineers

Geothermal Energy Applications Ground Source Heat Pump GSHP Shallow Boreholes Thermal Energy Storage BTES Aquifer Thermal Energy Storage ATES Geothermal energy storage systems Mid-deep Low Temp Geothermal Energy High Temp Energy Storage HT-ATES Deep High temp Geothermal energy

Short introduction UTES ATES Aquifer Thermal Energy Storage seasonal storage of energy and change of temperature direct cooling (USP) and/or heating (with heat pump) medium and large scale projects BTES Borehole Thermal Energy Storage natural temperature of the underground application of heat pump, limited in cooling small and medium scale projects Ideal for base demand of energy

Short introduction HT ATES Industrial Waste heat Greenhouses Residential area 90 C 70 C Underground waste heat storage Advantages of heat storage: Balance between seasonal heat demand and supply Increased security that there is an outlet for industrial waste heat, also in summer Back-up capacity in case of temporary interruption of waste heat delivery CO2 Saving thanks to the replacement of peak capacity and energy.

Innovation curve Europe 2012 HT ATES

Permits for large scale ATES systems in The Netherlands 1990 2000 2011 10 systems 200 systems 1500 systems

Feasibility ATES in Europe

Storage central role in future DHC Waste Heat SCP Agriculture Buildings Waste Incineration Industry PV Wind District Heating

Storage and DHC systems Seasonal storage: use of renewable natural resources (solar, air, water) o Heating: use of heat pump o Cooling: direct from the underground Heat/cold exchange between energy users High temperature storage: o more efficient use of waste heat o combined heat and power (CHP)

Benefit large scale applications Better use of renewabe energy sources by connecting users: o Houses (heat demand) greenhouses (solar collector) o Datacenter (cooling) student housing (heat demand) Big savings ask for big projects Market penetration can rapidly increase

Type of projects UTES and DHC Heating only Cooling only Heating / cooling Individual small single home Short term switch station small building Individual large data center, industry building Collective small Collective large housing area housing or greenhouse area greenhouse monoindustrial area building or housing area Mid term integrated area, greenhouse area

Urban energy planning Demand vs natural resources 2.000 houses

Applications in NL

DHC City of Amsterdam Heating: incineration Cooling: surface water or ATES

Comfort Cooling Concept NUON/Vattenfall Kadoelerbreek: Social nursing home for elderly 180 housing units, 3711 m2 of buildings 285 residential equivalents District heating with 320 kwt Comfort cooling Constructed in 2011 Houthavens: District heating with 1500 kwt Comfort cooling Feasibility study IF in february 2012

City centre of Rotterdam Masterplan ATES District Heating by Eneco Energy Local cooling with ATES, pieces of jigsaw Long term possibility: district cooling combined with ATES

BTES: Urban planning city of Ede about 1.950 houses 2 schools 5 RE developers small or large scale BTES? protocol about conditions

ATES: City of Groningen new buildings and existing stock small scale DHC integration with other networks

Principle collective ATES (small DHC) Each building a heat pump Demarcation of supply Use maximum capacity of a well Exchange energy Drinkingwater company supplies groundwater?

ATES: Science Parc Amsterdam (SPA)

ATES masterplanning Agreement 3 landowners to promote ATES warm and cold stripes, no interference between wells rules of ordening wells wthin a legal framework

Application in Science Parc Amsterdam Datacentre Student housing College TSA AUC TSA Duwo TSA Nikhef warme bron koude bron

Sustainable energy for NIOO, the Netherlands HT ATES: University Wageningen Engineering the earth Heats its building and greenhouses in an innovative way Using high-temperature energy storage No heat pump ATES: one warm and cold well HT: 45 o C well and 30 o C well

Future challenges Political support is essential Same legal rules in European countries Risk-sharing finance facilities Urban and underground (energy) planning very important From small scale to district scale From technology push to marketing pull NL is to small, IF likes to share solutions in your country
