2. 2 Conventional = 100% fossil + 100% losses Minewater vision Conventional energy supply November 2014

3. 3 Minewater vision District heating with CHP November 2014 Improvement = increase efficiency

4. 4 Heat pump New generation: exchange and storage = 2 to 5 times reuse with additional sustainable energy generation Minewater vision Sustainable energy supply November 2014

5. 5 Minewater 3.0 Design on use Peak load 200 – 400 hours (10–20 days): Feed temperature 38 – 45 ˚C Short term storage (hour/day) Base load 3600 hours (5 months): Feed temperature 30 – 38 ˚C Mid/long-term storage (week/month/season) Hot water demand < 2 hours/day: Heatloss HT-network 8760 hours/year > 35% total heat demand; LT-network + booster HP < 5%

6. 6 November 2014 Minewater 3.0 Low-Ex, storage and exchange Periods with extreme change in demand => though storage at building and cluster level instand (passive) exchange of heat and cold Peak load 200 – 400 hours (10–20 days): Feed temperature 38 – 45 ˚C Short-term storage (hour/dag) Base load 3600 hours (5 months): Feed temperature 30 – 38 ˚C Mid-term/long-term storage (week/month/season)
