Heat supplied by Indaver for Antwerp’s residential areas

It is possible that the Antwerp districts of Luchtbal and Rozemaai will soon be obtaining their heating from the port. The city of Antwerp, the Port Authority, Indaver and Fluvius are jointly examining whether residual heat from Indaver's incinerators can be used for sustainable heating of the residential area and individual companies. They have concluded a strategic partnership specifically for this.

Heat for residential area and companies

A lot of energy is released by Indaver's incinerators in the Antwerp Port area and this energy is converted into electricity for the grid. Indaver currently supplies the residual heat to Amoras, the dewatering project for dredger sludge from the Port of Antwerp, for heating buildings.  But there is still sufficient residual heat which could also be used for heating some neighbouring industrial sites and the districts of Luchtbal and Rozemaai, as a sustainable alternative to fossil fuels. The city of Antwerp, the Port Authority, Indaver and grid operator Fluvius will now study in detail how feasible this is.

Largest heating network in Flanders

If this heat project turns out to be a feasible option, and is delivered, it will be Flanders’ largest hot water supply grid in terms of capacity and will include the first ever large-scale pipeline to be laid from the port to the city centre for this network. The residual heat from Indaver will be transported 12 kilometres via this pipeline to 3,000 households, 7 schools and some public buildings in the residential area. Along its length, it will provide industrial clients in the port area with heat. 

Substantial reduction in CO2 emissions

This heat network would account for annual CO2 emissions savings of 27,000 tonnes. This is the equivalent of the annual savings by approximately 19 large windmills of 3.3 MW, or emission reductions by keeping 18,000 new cars off the road. Furthermore, the heating network can be expanded in due course to adjoining neighbourhoods and clients. 

In-depth study

The partners will now join forces for a further in-depth study which must make officially clear whether the installation of the heating network is economically feasible and can supply the clients with sufficient heat. The intention is also that the heating network users should not pay more for their heat than would be the case if they were to generate this themselves with natural gas. The parties intend to decide at the end of 2019 whether or not to carry out the project. 

Climate targets

A heating network is a pipeline network used to pump hot water from a manufacturer to consumers. The heat flows into homes and public or industrial buildings via a network of super-insulated pipes. This heat can then be used for heating rooms or for domestic hot water supplies.  This project fits with Indaver’s strategy of using as much waste as possible in energy or materials, and with Flanders’ own climate targets. Flanders will, therefore, be releasing 15.7 million euros from the Climate Fund.
