Residual heat is derived from a waste incinerator in the Port of Rotterdam and transported to the City of Rotterdam. The plant has a thermal exit capacity of 105 MW and the transportation system is an integrated double pipeline of 26 kilometers from the waste incinerator to where it connects into the existing district heating infrastructure in Rotterdam. The heat hub is a physical structure placed at a strategic location near the waste heat transportation infrastructure and the district heating system.

RO1 The Heat Hub focuses on increasing the effectiveness of the waste heat transportation network of Warmtebedrijf Rotterdam with buffering, heat balancing, smart ICT and forecasting. It allows for an increase in total heat delivery of the waste heat network without any additional investments in a new transport infrastructure or by means of additional heat sources.

The heat hub, operational since Q4 2013, contains three parts:

  1. The heat hub acts as a distribution station and it connects the existing district heating systems in the south and north of Rotterdam.
  2. The heat hub has a well-insulated buffering tank. The capacity of the buffer is 185MWh and the discharge capacity is 30MWth. By placing the tank in the middle of the distribution network, instead of at the traditional location in the vicinity of the production facilities, Warmtebedrijf Rotterdam increases the effectiveness of the buffering capacity, because the buffered heat is closer to the end-consumer. There is also a positive effect on the local air quality because there are less gas-fired boilers needed for peak load.
  3. For better forecasting and heat balancing, a smart ICT-system is under development. This ICT system is a crucial element in further optimization of heat sources, buffers, new connections and pumping stations in the waste heat transportation infrastructure of Warmtebedrijf Rotterdam and the entire district heating system. ​
