In this tenth episode, we discuss the future of heat networks as one of the main technical challenges in our ambition toward a fossil-free world. What exactly are heat networks? How sustainable are they? And which sources of heat should be applied?

A district heating network is as sustainable as the resources that feed it. Therefore, we need to move away from traditional district heating systems that are often dependent on one fossil fuel-based heat source to more sustainable ways of supplying heat. This transition comes with innovations and challenges. Innovations include the application of huge e-boilers, diversification in heat sources, and moving towards more flexibility in the supply of sources to our networks. What are the biggest challenges to overcome in these innovations? How dependent is district heating on the gas market? And how affordable is district heating for the consumer?

 Bart Dehue (Manager of Green Heat Source team at Vattenfall), Britt Verhesen (Project Leader of Energy Transition at the City of Antwerp), and Henk Jan Top (Managing Director Utilities at Accenture), discuss the future of heat networks and how sustainable district heating networks are. They discuss the challenges and possibilities of moving to sustainable heat sources.
