Developing and implementing toolbox integrations for storing excess heat generated by a PVT system

This thesis addresses a critical challenge in the field of renewable energy, focusing on the efficient utilization of Photovoltaic-thermal (PVT) systems. Despite their promising role in sustainable energy production, PVT systems often grapple with excess heat generation, impacting their efficiency and longevity. The primary objective of this...

Short-term operational stability of 5th generation district heating and cooling substations: Performance improving control strategies for prosumer substations in an ATES ring network

Energy demand for heating and cooling makes up 73\% of total energy use of buildings [2]. This figure is expected to increase over the coming decades, as demand for cooling energy may rise in the Netherlands due to climate change. The heating and cooling of buildings are at relatively low temperature compared to the industry and thus allowing...

Advancing Adoption of Aquifer Thermal Energy Storage: a New Evaluation Method to Support Local Decision-Makers: Assessment of the Technical and Commercial Potential of Aquifer Thermal Energy Storage in New York State Considering the Requirements and Interests of Key Stakeholders

Aquifer Thermal Energy Storage (ATES) is a geothermal technique that is an important component in the transition towards renewable energy in the heating and cooling industry, which accounts for half of the world's energy consumption. However, the technology has not yet been implemented in many countries. The main reason is that extensive...

The influence of installing UTES boreholes on the bearing capacity of piles

The transition to renewable energy has lead to many new ways of energy production, such as wind and solar energy. For solar energy power, there is an excess of energy during summer and an deficiency of it during winter, which is reversed for the energy consumption. In order to amend this problem, there is an introduction of new ways of energy...

Counteraction of buoyancy flow in high temperature aquifer thermal energy storage systems by applying multiple partially penetrating wells

The thermal recovery efficiency of High Temperature Aquifer Thermal Energy Storage (HT-ATES) systems can be limited due to the effect of buoyancy flow of the injected hot water. This thesis has researched the application of a Multiple Partially Penetrating Wells (MPPWs) as a well design method to counteract the effect of buoyancy flow and...

Interaction between multiple ATES systems: Analysis of thermal and geohydrologic performance

Aquifer thermal energy storage (ATES) is a sustainable technology that provides thermal energy to buildings in temperate climates. The principle of ATES is to temporary store thermal energy in aquifers in a warm and cold well in order to use this thermal energy for heating and cooling in the next season. Because the available subsurface space is...

Potential of polymer sewage heat exchangers with enhanced thermal properties

Buildings contribute to 30% of global CO₂ emissions and consume 40% of the global energy supply (Yang et al., 2014). Heating and cooling requirements of the buildings form the major part of the energy consumption in buildings (Culha et al., 2015). Thus to solve this problem, one of the solutions currently being<br/>looked at is to...

Aquifer thermal energy storage following up on the tu delft geothermal well: A study on how a low-temperature aquifer thermal energy storage system can cool and heat the campus in accordance with its climate goals by 2050

In 2020 TU Delft will build a geothermal well producing enough energy to power all its faculties and a number of buildings surrounding the campus. This is done to meet the climate goals the TU set itself: an energy neutral campus by 2040. Geothermal plants are designed to produce for 30 years. After this period, by 2050, the TU has to be energy...

The suitability of High Temperature – Aquifer Thermal Energy Storage in Holland-Rijnland

High Temperature – Aquifer Thermal Energy Storage (HT-ATES) is a way to efficiently store heat with use of the subsurface. Region Holland-Rijnland has the vision to be free of the use of natural gas in 2050. A proposed high temperature heating network from the port of Rotterdam to the households of Leiden, combined with the use of an HT-ATES...

Effect van variaties in chloride concentratie op de efficiency van een warmte- en koudeopslag systeem

This research is executed to study the effects of density driven currents and their effects on Aquifer Thermal Energy Storage Systems(ATES).<br/><br/>A monowell system is studied in the location of Amsterdam, in the Netherlands. Due to saline water deep in the ground and fresh water higher in the ground, there is a gradient in density in the...

Determination of optimal separation well distance for single borehole ATES systems, in the Netherlands, implementing an an axi-symmetric numerical model

Aquifer thermal energy storage (ATES) is a growing technology in the Netherlands. There are two kinds of ATES configurations the doublet and the single borehole ATES (SB-ATES) layout. The limited subsurface space in combination with the lower construction cost and the lower performance of the SB-ATES lead to the need to optimize their design....

Optimal use of the subsurface for ATES systems in busy areas

With the incentive to reach the energy saving and CO2 emission reduction targets of the Netherlands, the application of Aquifer Thermal Energy Storage (ATES) is expected to increase sharply during this decade [2]. With limited aboveground and underground space, well arrangement is becoming difficult in busy areas with a rapidly growing number of...
