Wester, Niels (author)The Port of Rotterdam Authority (PoRA) aims to be CO2 neutral by 2050. To achieve this goal, they have proposed three steps to make an energy transition. The transition focuses on shifting from fossil energy towards renewable energy, like wind energy, hydrogen and geothermal heat. The Port of Rotterdam (PoR) is an important area to make this...master thesis 2021

Maat, Sander (author)The goal of this study is to test out the accuracy of the upscaling approach (Jinyu Tang, 2021) for a geothermal doublet. This approach tries to simulate the physical thermal dispersion. When modeling in a geothermal reservoir it would be easy if a lot of layers can be upscaled. However, when doing upscaling one can not just take an average of...bachelor thesis 2021

Dhauri, Sha'ief (author)Projections show that urban areas are growing at an increasing rate and produce 60% of the global greenhouse gas emissions (United Nations, n.d.). In Europe, the thermal energy sector consumes about half of the energy resources, of which 85% is produced by fossil fuel-based energy systems (Drijver, Bakema, & Oerlemans, 2019). As a result of...bachelor thesis 2021

Kane, Entela (author)The Netherlands has set the ambitious goal to be CO2 neutral by 2050 and signed the Paris Treaty in 2015. The contribution of geothermal energy to reaching this goal are outlined in the Masterplan in 2018 which attempts to reduce CO2 emissions. It is imperative to enhance geothermal participation in renewable energy resources, so this thesis...master thesis 2021

de Vries, jorrit (author)As part of the effort to make the Dutch waterways CO2-neutral, a consortium consisting of, among others, CRUX Engineering BV and Delft University of Technology, initiated a case study in which the thermal and mechanical performance of an energy sheet pile wall is studied. This technology allows for the extraction of energy from the water and...master thesis 2021

Doff, Jelmer (author)To produce accurate 3D fluvial architecture models, it is important to understand the influence of internally generated autogenic controls versus externally generated allogenic controls. When studying a fluvial system, autogenic controls such as river meandering and avulsions generally dominate over 103-104 years. Allogenic controls such as...master thesis 2021

Ghafuri, Seleyman (author)This research is intended to create an insight into the heat exchange occurring in a well and to find ideal well conditions in which the performance of the heat exchange is maximised. For demonstrating and studying these aspects the well of Grouw-01 is analysed. The well of Grouw-01 is a depleted gas well attained from Vermilion Energy and is in...master thesis 2021

Maltha, Niels (author)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...master thesis 2021

Scheenaart, Nienke (author)The TU Delft (strategic framework 2018-2024) aims to have a CO2 neutral and circular campus that departs from the linear economy to closed material cycles by 2030, meaning that the campus becomes climate neutral. Currently, the TU Delft is accountable for 47.957 tCO2-eq emissions, uses 166.038 MWh of energy for electricity and heat , and is for...master thesis 2021

Aldyth Alem Iskandar, Aldyth (author)In a future scenario, the successful development of geothermal industry will result in the large-scale deployment of new deep geothermal projects. In highly populated areas, such as the Netherlands, such a development will lead to a dense grid of neighbouring licenses. In such a situation a new project requires careful design and planning as the...master thesis 2020

Marelis, Arjan (author)Accurate and efficient predictions on the behavior of fluid flow and heat transport are required in the development of low-enthalpy geothermal reservoirs in fractured formations. Key challenges include the demand for high-resolution computational grids, the non-linear behavior of the system due to strong mass-heat coupling and the presence of...master thesis 2020

Grubben, Tessel (author)Geothermal energy reservoirs can be used as sources of renewable and sustainable energy. The concept of geothermal technology relies on the harvesting of heat from the deep rock by injecting fluid that circulates through the porous, fractured reservoir rock between the injection and production boreholes, and thereby transports the heat to the...master thesis 2020

Wang, Chenyang (author)Transition to cleaner energy while sustaining the heat demand necessity has always been an emphasized topic in the recent years. With the slowly declining utilization and production of natural gas in Netherlands, geothermal energy shows a promising future in providing sustainable power for heating and various applications. For majority of...master thesis 2020

de Wildt, Midas (author)The current production of geothermal heat is not yet considered completely sustainable, since CO2 is emitted. The majority of the emissions from geothermal energy are related to formation gas, for the majority consisting of CO2 and methane (CH4). The amount of (resulting) CO2 emissions due to formation gas is determined by the composition and...master thesis 2020

Draškić, Marko (author)Large quantities of heat stored in geothermal aquifers can be of interest to satisfy above-ground heating demands. With the use of heatpipes, placed into the aquifers, heat may be passively extracted. Vertical two-phase thermosiphons are considered in this study. As a result of a local increase in the saturation temperature in liquid pools, heat...master thesis 2020

Kortram, Jon (author)Geothermal energy is one of the more sustainable alternatives to fossil fuels that could facilitate the energy transition. The production of geothermal energy incorporates the use of corrosion inhibitors to protect the steel well-parts from the corrosive production fluid. The injection of inhibitors leads to a risk of exposing the reservoir rock...master thesis 2020

Naranjo Hernandez, David (author)In 2017 the National Power Company in Iceland, Landsvirkjun, started the operation of a geother- mal power plant in Theistareykir (Northeastern Iceland). The plant’s operation requires extraction, circulation, and injection of the geothermal fluids to produce energy. These processes depend on the existing fracture network of the reservoir....master thesis 2020

Atiş, Ebru (author)Due to an increase of precipitation reactions in water by temperature changes, cloggings canoccur in a geothermal doublet. A consequence of the cloggings is that the process of generatinggeothermal energy becomes inefficient eventually.

Nieuwstad, Bas (author)Geothermal energy can be a great solution for the downscaling fossil fuel society, but it can potentially lead to seismic hazards. A doublet system, with a cold water injection well and a hot water production well, alters the stress situation in the subsurface, which can result in (micro)fracturing and fault reactivation. Even in water filled...master thesis 2020
