Heat transition in NL = growth of ATES & BHE 8,000,000 buildings = 25% of total NL energy use
– ~6,500,000 houses – ~1,500,000 utility buildings – ~10,000 ha greenhouses
• Currently: ~1% have ATES/BHE • In 2050: ~25%

Legislation situation: permitting
• Reporting obligation • 6 wk permit procedure • HT-ATES Pilots allowed
• In busy areas: possibility to plan • Reporting of performance
6
Legislation situation: certification
• Design, Build, Operate • Drilling& completion,
Climate installations
7
Rationale for certification
• Allow (partly) irreversible disturbances in the subsurface
• GHG emission must go down

BTES borehole completion

BTES borehole completion • Clay/bentonite • Cementing
• Verification techniques

Integration in heat-networks
• Redundacy in supply and off-take
