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
Underground waste heat storage
Greenhouses
Industrial Waste heat
Residential area
90°C
70°C
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.

Storage central role in future DHC
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

Heating: incineration Cooling: surface water or ATES
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
Comfort Cooling Concept NUON/Vattenfall
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

Sustainable energy for NIOO, the Netherlands
• 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 oC well and 30 oC 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
