2. Traditional Urban Energy Infrastructures
Heat Grid
Electricity Grid
Gas Grid

3. Towards an Hybrid Energy Grid
Traditional Grids
The Hybrid Energy Grid
1. Heat Pump can transfer a surplus of electricity into heat.

3. Heat can be stored for later use.
CHP 2
The share of renewable energy is increasing.
Hybrid energy systems can absorb these fluctuations

4. Example of a Hybrid Energy Grid
Electricity
Heat Pump
Geothermal Energy
Ammerlaan, The Netherlands
Combination of geothermal energy and heat pumps.
Heat pumps are used for additional heating in case of peak demand.

5. How to efficiently manage a hybrid energy system (1)?
Many different devices, different vendors

8. Urban applications 1. Heat Grid Optimisation
Optimise both traditional and renewable heat sources in a sustainable heat grid (HeatMatcher).
2. Heat roundabout
Optimise use of waste heat and cold (eg Province Zuid –Holland).
3. Building to Grid
Optimise HVAC (heating, ventilation, air conditioning) and lighting, leading to increased energy efficiency.
4. Smart Hybrid Control
Smart control in a hybrid energy set-up with different heat sources, depending on the electricity and gas price and heat demand.
Prototyping in HESI-lab at EnTranCe (Groningen)
