1. EC CONCERTOII project REMINING-LowexPresentation for the CONCERTO meeting,November 14, 2011 – Brussels, BelgiumExtracting energy from minewater Erwin Roijen Cauberg-Huygen Consulting Engineers Maastricht the Netherlands

2. What is REMINING-Lowex about? • Developing sustainable communities in mining and former mining areas > transition to clean energy • Balancing the local energy demand (buildings) with the local available low valued energy sources (renewables, i.e. minewater, but also other renewables)

3. The Remining-lowex locations update on developments and progress
