ATES-smart grids

ATES-smart grids

Due to large demand for ATES many urban aquifers experience scarcity of space to accommodate the demand for ATES systems. Under current practice ATES wells are placed at large mutual distance. This distance can be reduced when applying a self organization planning governance structure together with a Distributed Model-based Predictive Control (D-MPC).

ATES Triplet

ATES Triplet

In this work, a novel ATES system without a heat pump is proposed which now uses three wells (a triplet), solar heat collectors and a dry cooler. The use of heat pumps is avoided, vastly reducing the electricity required. The basic working principle shows great potential but needs development on robustness and monitoring, and integrated control of the building’s heating and cooling systems, as well as on the processes in the subsurface to ensure system longevity.

Warming Up

Warming Up

The WarmingUP collective brings together 38 participants to make collective heating systems reliable, sustainable and affordable for the heat transition. System and process innovations are necessary for improved designs, construction and management. WarmingUP wants to develop these innovations at an increased pace.

Energy Piles in the Netherlands

Energy Piles in the Netherlands

The energy piles will warm and cool buildings through their pile foundations by using the natural temperature of the soil. An 18-meters deep hole is drilled in TU Delft’s Green Village, containing detailed instrumentation in the energy pile foundations in order to test and speed up their use on the market. The aim is to standardize the pile technology up to 30-meters-deep and help the industry build more eco-friendly constructions.

Energy Quay Wall

Energy Quay Wall

The energy quaywall utilises energy sheet pile walls to provide heating and cooling for space heating from water in canals and the soil adjacent to and under the canals. Heat storage is also provided by changing the temperature of the soil.
