van de Griendt, Toon (author)Currently, a large part of the energy used to provide heat to heating network comes from gas boilers, a combustion process where 2.2kg of CO2 is emitted for every m^3 of gas. Deep geothermal energy is implemented more in The Netherlands over the last couple of years as a substitute to the conventional boilers and this is a technique that is...master thesis 2022

Smit, Freek (author)Geothermal energy in the Netherlands is growing in general, however, medium deep geothermal (200 - 1500 m depth) is lagging behind while the potential at these depths could be very high. Development is held back by little geologic knowledge of this interval as well as legislative constraints. Better understanding of the reservoir characteristics...master thesis 2022

Wurmböck, Octavio (author)Aquacultures are rapidly increasing worldwide to meet the rising protein demand caused by population growth. However, commonly used fish feed products are known to harm the environment while depleting natural species. Various microbial protein forms are thus being investigated, such as those using hydrogen-oxidising bacteria, referred to as MP....master thesis 2022

Hassing, Sverre (author)CO2 and H2S are reinjected at Hellisheiði, Iceland, to reduce the emissions of greenhouse gases. An active-source seismic campaign was done in July, 2021, to image the reinjection reservoir with various seismic methods for consecutive monitoring. At the same time, passive-source seismic data was recorded for imaging.<br/>We process this passive...master thesis 2022

Barreiros Jorge, Sofia (author)Subsurface energy projects carry high risk due to the lack of data available to accurately model reservoir characteristics. There is a need for high level analysis to extrapolate subsurface data from a single point (i.e. a well). The focus of this study will be on fracture characterisation in a carbonate reservoir located within the Geneva Basin...master thesis 2022

Biagini, Maria Erica (author)In a world transitioning towards renewable energies and lithium-battery powered cars, there has been an annual increase in demand of 6% for lithium and other rare metals between 2000 and 2008 (Stringfellow & Dobson, 2021a), and this increase in demand is forecast to continue through 2040 (Latnussa et al., 2020). Meanwhile, there is a concern...student report 2022

den Ouden, Carleyn (author)To run Nature’s Heat geothermal operations (Kwintsheul, The Netherlands) in a safe and efficient manner, and with the support of the local population, it is important to mitigate potential hazards. A well known potential hazard related to geothermal operations is the occurrence of induced seismicity due to injection and extraction of fluids in...bachelor thesis 2022

Fehnker, Hauke (author)The North German basin holds high potential for geothermal lithium exploration. Yet, so far, the assessment of reservoirs concentrates on locations in the Upper Rhine Graben. This thesis gives an example for the evaluation of a potential geothermal lithium reservoir of the Middle Buntsandstein at the location Horstberg in Lower Saxony. The...master thesis 2022

Andriopoulos, Sief (author)The Paris Agreement was created in an effort to enhance the global response to the issue of climate change. To reach this goal, greenhouse gas emissions must be at least 40% below 1990 levels by 2030 and the temperature rise must be kept below 2 degrees Celsius this century. Moreover, the recent fossil fuel price increases, are pressing eye...master thesis 2022

Tripathi, Anushka (author)Global energy transition is crucial in mitigating climate change. Numerous initiatives are being taken globally to achieve a carbon-neutral energy system. These goals require a complete shift from non-renewable energy sources to renewable sources like geothermal energy. These renewable sources of energy have to be constantly improved in order to...bachelor thesis 2022

van de Weijer, Paul (author)Geothermal sources could provide society with clean and renewable energy nearly eternally. Geothermal district heating, in particular, could play a significant role in the energy transition. Although the application has been implemented to some extent, further upscaling is challenging due to various economic, technical and institutional...master thesis 2022

Margert, Andrei (author)Acidizing is a widely used technique for intensification of geothermal wells. At certain conditions, acid injection results in a formation of highly conductive channels, e.g. wormholes. The associated rock matrix dissolution is highly nonlinear and may influence the fluid flow as well as rock properties. Wormhole patterns and breakthrough time...master thesis 2021

Verweij, Cas (author)In the energy transition from fossil fuels to less polluting renewable energy sources geothermal energy are considered as a promising technology. Gasses such as CO2 are often dissolved in geothermal waters. With the extraction of these fluids from the reservoir, a change in pressure will occur towards the extraction well which may cause...master thesis 2021

Hartemink, Ewoud (author)The rising demand for clean energy has drawn the attention for more geological research to low enthalpy geothermal applications in the Netherlands. A multi-scale reservoir characterization is carried out with the aim to understand the geothermal reservoir potential of the Triassic Main Buntsandstein (RBM) in the Tilburg area. Seismic data, well...master thesis 2021

van Lith, Floris (author)The Indonesian government has set a target to increase new and renewable energy sources in the energy mix by 23% in 2030 and 31% in 2050, which are to be met by investing in hydropower and geothermal energy capacity mainly. However, Indonesia has abundant other renewable energy potentials, which are largely untapped. The Java-Madura-Bali (Jamali...master thesis 2021
