WHY LEAN?
Dutch geothermal energy ambition: 200 PJ/year
White Spots might have potential
2D seismiek (nlog.nl) 3D seismiek (nlog.nl) Boorgaten (nlog.nl)
Up to now no geothermal development at White Spots (too risky)
LEAN objective to demonstrate innovative approach for economic development of geothermal energy at
White Spots
