Aquathermal Viewer shows potentials for heat from waste and surface water

Published: 1 March 2020

Deltares and Syntraal have launched the Aquathermal Viewer in collaboration with STOWA. The viewer shows in detail the potentials for heat from surface water and waste water at the regional and local levels. Municipal authorities, energy strategists and water managers can use that information to establish a picture of the contribution that aquathermal sources can make to the heating transition.

Deltares has refined the results of the ‘National aquathermal potential’ study from 2018 and extended it to include small waters. These results have now been included in the Aquathermal Viewer, an interactive map that shows the potential for thermal energy from surface water in a specific region, municipality or district. This potentials map can help municipal authorities and other stakeholders in their deliberations about how to make their built-up areas more sustainable. Consultancy firm Syntraal updated the basic data for thermal energy from waste water.

Aquathermal potential in the Initial Analysis

Municipal authorities are required to produce a Heating Transition Vision by the end of 2021 that sets out their approach for making their municipalities sustainable and free of natural gas. One of the tools that the authorities can use to establish a Heat Transition Vision is the Initial Analysis. This is a technical and economic analysis based on national data produced by the Netherlands Environmental Assessment Agency (PBL) in the Vesta MAIS model. It includes calculations for alternative sources of heat. The PBL used the potential thermal energy from both surface and waste water as input for this initial analysis, which will be made available to the municipal authorities in late March.

WarmingUp programme

Deltares has contributed the initial results of the WarmingUp programme, which brings together parties in the heating sector. The main goal of this programme is to develop collective heating systems that are affordable, sustainable, reliable, practical and socially acceptable. The development of the viewer has been financed by the water management and regional energy strategies programme with a subsidy from the Ministry of the Interior and Kingdom Relations.
