Schifflechner, Christopher (author)
The utilization of deep geothermal resources for combined heat and power generation in Germany has increased slowly but continuously during the last years. Due to the growing technical readiness, the focus is now shifting from the first proof of concepts to optimizing the performance of existing plants. One promising approach is the further...

The building sector currently accounts for approximately one-third of the global demand for energy, and one-fifth of all energy-related greenhouse gas emissions (GHG). The development and adoption of energy-efficient technologies in this sector is therefore a key element towards efforts for the mitigation of climate change. In particular,...

A transition to a low carbon energy system is needed to respond to global challenge of climate change mitigation. Aquifer Thermal Energy Storage (ATES) is a technology with worldwide potential to provide sustainable space heating and cooling by (seasonal) storage and recovery of heat in the subsurface. However, adoption of ATES varies strongly...

Geothermal energy is a relatively sustainable energy source of which the essence is to extract heat from hot subsurface rocks. Circulating fluids serve as the transport agent of heat. The contact area between the fluids and the rocks is where the relevant heat transfer occurs, i.e., where the water is heated up. In some geothermal reservoirs,...

The decrease in the production of hydrocarbons in combination with a growing urgency to reduce carbon emissions drives a rapid study and application of geothermal energy in the Netherlands. The produced heat from the low enthalpy geothermal energy can be used for heating up the buildings and greenhouses. A doublet system is used in the...

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]
In order to overcome this fast increase, the human...

To develop high enthalpy geothermal systems in the Netherlands, reservoirs with a depth greater than 4000 m need to be targeted. The Lower Carboniferous limestone is proposed as the main target due to its depth and wide occurrence. To investigate the potential of this formation, the physical rock properties are studied in a variety of laboratory...

Royal HaskoningDHV is currently exploring ultra-deep geothermal heating systems in the Netherlands. Within this research it was analyzed whether people show different levels of emotions when being confronted with ultra-deep geothermal energy projects, and whether there are differences in antecedents of emotions between people living in an area...

In a Borehole Thermal Energy Storage (BTES) system, heat is extracted from or injected to the subsurface, taking advantage of the relatively constant temperatures of the underground. Both thermal conduction and advection can influence the performance of BTES systems, but thermal advection is often neglected in the design process. However, in...

Aquifer Thermal Energy Storage (ATES) systems provide sustainable space heating and cooling for buildings. In future, many buildings in moderate climates rely on ATES for their space heating and cooling.
However, the subsurface space available for heat storage is limited and, there is a trade-off between individual ATES system efficiency...

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...

Geothermal energy is a way of reducing the cost of energy. Deep geothermal energy systems extract heat from very deep soil layers where the temperatures are very high. Shallow geothermal energy systems are about 150 metres deep and they are used to store heat in the soil, to extract it later and use it for space heating. These shallow geothermal...

The Dutch Government is aiming for a CO2 neutral energy supply in 2050; this requires a transition from using energy from fossil fuels to using renewable energy sources. Decline in oil production in the Netherlands occurs in an epoch with an increased interest in geothermal heat production as an alternative source of energy. In the present study...

With an increased demand for renewable energy sources, geothermal developments have moved into the spotlight, including sedimentary structures. In the western part of the Netherlands, cretaceous sandstone bodies are already in use for the geothermal energy production. However, these reservoirs are generally producing water at temperatures less...

Required distance between doublet systems in low enthalpy geothermal heat exploitation is often not fully elucidated. The required distance aims to prevent negative interference influencing the utilisation efficiency of doublet systems. Currently production licence areas are often issued based on the expected extent of the reinjected cold...

Heating constitutes about 40% of the final energy consumption at TU Delft. In the present, the district heating system in campus obtains its energy from the combustion of natural gas in a combined heat and power plant. Although this plant produces heat and electricity with an efficiency over 80%, the dependance on a fossil fuel presents an...

Deep geothermal energy gained more and more attention in the Netherlands over the past few years. It is a renewable energy source with limited air emissions and it can provide reliable base-load power. Since 2007 eight installations were built and more than hundred exploration permits were approved by the Dutch authorities. Many energy firms are...

In this thesis, the feasibility of a geothermal doublet in the former Barendrecht gas field is investigated. The aim of this work is to stay as closely as possible to the original well configuration. An IMPEXS model for the movement of the cold-water and thermal front is built to calculate the possible potential of the field. Wellbore heat...

Goal of this project was to get a better understanding of the producing formations in the two doublets in the Van den Bosch Geothermal energy concession in Bleiswijk. It can be concluded based on the GR logs in VDB-04, the lithologs, End Of Well reports, a Biostrat log in VDB-04 and the seismic interpretation that the first doublet (VDB-01 & VDB...
