In the Netherlands, 50% of energy consumption is heat-related. The heating transition is a necessary step on the road to more sustainable heating in the built environment and the reduction of carbon emissions. In warm areas, there is actually demand for cooling. Water and the subsurface play a significant role in the use of sustainable energy-ecient heating and cooling systems. What are the questions and opportunities in this area where Deltares together with partners can help? ... we see the challenges and opportunities for the heating and cooling transition in the built environment .... and demand for cooling from heat demand... EXAMPLES OF HOW THE DELTARES KNOWLEDGE IS APPLIED The heat chain can be used for heating in the winter and for cooling in the summer. WINTER AND SUMMER, HEATING AND COOLING i Independent partner for many parties, lynchpin. How do we deal with the concentration and construction of the underground infra- structure , what are opportunities for smart linkages. Optimal use of the subsurface and surface water so that cold systems can be made more sustainable. Legal and technological expertise about the effects of more ATES (aquifer thermal energy systems) in the subsurface, for example associated with interference from multiple systems. Deltares addresses integration issues, the performance of the system and the monitoring of the effects on the subsurface. Deltares knows how to scale up the use of heat in the subsurface responsibly. Effects of large-scale temperature extraction from water on ecology. How can we make optimal use of renewable resources to coordinate supply and demand ? ? Support for policy processes and administrative dilemmas grounded on thorough knowledge. The heat chain is becoming more complex . End users can also, for example, be suppliers. Integration of residual heat from industry Aquathermal: energy from surface water ? + + + What are the effects of the heating and cooling transition in combination with other challenges ? ? ? ? ? ? We use WANDA, Delft3D, iMOD and RTC-Tools to simulate water and subsurface processes, and visualise the effects on water and the soil in order to optimise systems. What can aquathermal systems contribute to the heating transition? Deltares produces charts that show in detail the potentials for heat from surface water and waste water at the regional and local levels. Which soils in Europe are suitable for ATES and what are the advantages and disadvantages? POTENTIAL OF SURFACE WATER AND ATES MONITORING OF SUBSURFACE WARMINGUP THE ZONNET SOFTWARE AND TOOLS SPATIAL PLANNING AND POLICY With glass-fibre monitoring systems, among other things, we can under- stand how energy storage in ATES systems is developing underground and we can get a better grip on the system so we can optimise it. What are the effects of aquathermal systems on the ecology, at the district, city and regional levels? Transition pathways from strategy to practicality. Which choices and dilemmas are involved and how do you take them into account in your policy? How can heat systems be integrated in spatial plans? Technical and economic feasibility of a new residential heating concept with locally-generated solar heat, heat pumps, and an aquifer thermal energy system (ATES) in the subsurface. Homes in Haarlem dating from the 1930s show that this concept is feasible in existing buildings. Infographic design - Studio Dirma Janse for Deltares Applied research for the realisation of reliable, sustainable and affordable collective heat systems. Collaboration throughout the heat chain - from heat suppliers to consumers, from source to delivery. Aquathermal + - Technological expertise... With applied research, we develop sustainable, acceptable and affordable heating and cooling infrastructure ...decision-making expertise, Deltares has a clear picture of the system and the possibilities. That makes it possible to set out possible adaptive solutions and support choices. ? Challenge/question Solution/opportunity Legend ?
