In this report, the tidal method is used to estimate hydraulic aquifer parameters. The principle of the tidal method is to use head fluctuations in observation wells, caused by tidal motion in a sea or river, to determine regional hydrological characteristics of an aquifer system. As the wave propagates into the aquifer, the amplitude of the...

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 global greenhouse gas emissions from energy use in buildings and agriculture accounts for 17% and 18% respectively, which has a significant impact on climate change. Therefore, both the sectors are actively looking at energy-efficient methods to reduce their carbon emission by shifting to more sustainable solutions. One such solution is...

Underground thermal energy storage (UTES) is an efficient technique to fulfill the heating and cooling demand of buildings. UTES uses stable subsurface temperatures store and extract energy. This study covers two types of UTES systems: aquifer thermal energy systems (ATES) and borehole heat exchangers (BHE). UTES systems in the Netherlands have...

Hydraulic properties of aquifer systems are usually estimated by conducting field experiments, which are called aquifer tests. Different approaches have been applied to simulate the drawdown data, such as graphical type curves, analytical solutions, and grid-based models. Since the type of groundwater system varies greatly from location to...

All over Europe, the expansion of renewable energy sources is quickly proceeding, fueled by environmental and political motives. The power generated by renewables is heavily subject to the intermittency of the source, e.g. the availability of wind or solar irradiance. Consequently, electrical grids that rely on renewable sources alternate...

High temperature aquifer thermal energy storage (HT-ATES) can potentially solve the mismatch between heat supply and demand. It can provide a large scale seasonal heat storage solution. Thereby it enables an increase in full load hours of the base heat source, which can benefit project performance on both costs and emissions. However, the...

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...

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...

Globally, growing demand for fresh water and declining water availability puts significant pressure on water resources. Due to rapid urbanization and insufficient water resource planning and waste water management, the Kathmandu Valley (Valley) is facing both a water quantity and quality crisis. Annually, groundwater extractions in the Valley...

The northern Ghana climatological conditions are favourable for agricultural production. The annual average precipitation of 800-1250 mm/y is theoretically sufficient for farmers to be year-round self-sufficient. However, the majority of precipitation falls in a 4-month wet season spanning from late May to October. As a consequence, the region...

Subsurface carbon dioxide (CO2) sequestration is a promising technology to reduce the CO2 emission into the atmosphere. After injection into subsurface formation, the carbon dioxide plume can migrate several kilometres until it is fully trapped. Four major mechanisms play an important role in trapping which include structural trapping, residual...

One of the methods of reducing the amount of CO2 in the air is CO2 sequestration by dissolving the gas underground in an aquifer. In practice,there will be impurity gases in the injected CO2 stream or in the aquifer, which influence the dissolution rate of the CO2 stream. This research aims at finding a method to evaluate and calculate this...

High Temperature Aquifer Thermal Energy Storage (HT-ATES) systems can be implemented to store geothermal energy, residual industrial heat and solar heat. Due to the large temperature differences between the injection fluid and ambient groundwater, buoyancy flow occurs, which causes heat losses which in turn results in poor efficiency of such...

This study introduces a new concept of ATES system, which is called ATEST system, to fulfill the transport function while crossing the barriers in water transmission and pipe replacements. Firstly, analytical models were used to help understand the physical process and range the working conditions of the ATEST system. Then numerical models were...

Sand replenishments, or nourishments, have been the prevalent strategy of the Netherlands for coastal protection since 1990. In consideration of the expected sea level rise and potential increases of storm surges as a result of climate change, an innovative pilot project known as the ‘Sand Engine’ has been implemented. In contrast with...

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...

Since the 1990th Sasol, a local Non-Governmental-Organization (NGO), builds sand storage dams, to mitigate the consequences of droughts in the semi-arid county of Kitui, Kenya. Sand storage dams are dams constructed in ephemeral rivers which increase the storage capacity of the riverbeds. The water stored by sand storage dams enables local...

Consider a managed aquifer recharge system in the Netherlands where approximately 25 million cubic meters of pre-treated water is infiltrated and recovered annually for the purpose of disinfection, buffering, and attenuation of water quality. The system consists of a sequence of alternating, parallel elongated recharge basins and rows of...
