Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved before robust operation in this temperature range can be achieved. In this study, yield- and tensile strength data for...

Successful electrification of cities' heating and cooling demands depends on the sustainable implementation of highly efficient ground source heat pumps (GSHP). During the last decade, the use of shallow geothermal energy (SGE) resources in urban areas has experienced an unprecedented boost which nowadays is still showing a steady 9% market...

The use of geothermal energy in Europe is expected to grow rapidly over the next decades, since this energy resource is generally abundant, ubiquitous, versatile, low-carbon, and non-intermittent. We have expanded and adapted the integrated assessment model TIAM-ECN to more adequately reflect geothermal energy potentials and to better represent...

In the geothermal energy domain, it is common practice to drill a doublet (i.e. an injection and production well pair) system for heat production from the subsurface. Injector-producer spacing typically varies between 1 to 2 km. This well spacing distance is usually chosen through engineering judgement. The concept of drilling doublet systems is...

The use of geothermal energy is expected to grow rapidly over the next several decades at many places in the world, since geothermal resources are abundant, and because this renewable energy option is both a low-carbon and non-intermittent technology. With the integrated assessment model TIAM-ECN we quantify how large its growth could be until...

In 2017 TNO and GFZ combined a dense accelerometer based high resolution surface seismic survey with a fibre optic based Vertical Seismic Profiling (DAS VSP) survey. The combined survey took place on a narrow patch of land in a challenging, noisy urban environment, in Berlin, Germany. The objective was to demonstrate the possibility to acquire a...

Geothermal development in aquifer settings can benefit considerably from a wealth of subsurface data acquired over the past decades by oil and gas exploration and production. In the Netherlands, this data has been gathered by the Geological Survey and has been made publicly available (www.nlog.nl). Almost a decade ago this data was used to...

Wells used for steam-assisted gravity drainage (SAGD), for cyclic steam stimulation (CSS), for hydrocarbon production in areas with anomalous high geothermal gradient, or for geothermal energy extraction all are operated in high temperature environments where maintaining long term wellbore integrity is one of the key challenges. Changes in...

High temperature aquifer thermal energy storage (HT-ATES) can contribute to the integration of renewable energy sources in the energy system, the replacement of fossil fuel-based heat supply and the utilization of surplus heat from industrial sources. However, there is limited understanding on the drivers, barriers and conditions of HT-ATES...

In this paper we present results of a global resource assessment for geothermal energy within deep aquifers for direct heat utilization. Greenhouse heating, spatial heating, and spatial cooling are considered in this assessment. We derive subsurface temperatures from geophysical data and apply a volumetric heat-in-place method to improve current...

The presence of convective fluid flow in permeable layers can create zones of anomalously high temperature which can be exploited for geothermal energy. Temperature measurements from the Luttelgeest-01 (LTG-01) well in the northern onshore region of the Netherlands indicate variations in the thermal regime that could be indicative of convection....

Faults can determine the success or failure of low enthalpy geothermal projects. This is due to their capacity to behave as pathways or baffles to geothermal water (or both simultaneously) and their prevalence throughout the subsurface. Here we present an initial assessment of the possibility for faults in the Northern Belgium (Flanders) and...

Subsurface temperature is a key parameter for geothermal energy prospection in sedimentary basins. Here, we present the results of a 3D temperature modelling using a thermal-tectonic forward modelling method, calibrated with subsurface temperature measurements in the Netherlands. The first step involves the generation of a coherent dataset of...

At present, the worldwide geothermal energy production provides less than 1% of the world's energy needs but the geothermal resources confined in the first 6 km of the earth's crust are estimated to be in the fairly above 200 GW of which 50-80 GW are located in Europe. Exploring and developing at large scale untapped hydrothermal resources...

After the first energy crisis in 1973 various research programmes to do with energy conservation and diversification of energy resources were set up in the Netherlands. A number of these were directed to the rest of the subsoil for the following purposes: - the extraction of geothermal energy from great depths (1800-3000 m below surface); - the...
