ATES and BTES developments in the Netherlands: Optimization and Upscaling

dr. Martin Bloemendal, dr. Niels Hartog, dr. Frank Agterberg, Der Geothermiekongress, Munich, 2019-11-19

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

8

BTES borehole completion

BTES borehole completion • Clay/bentonite • Cementing

• Verification techniques

Integration in heat-networks

• Redundacy in supply and off-take
