Project Description:

The core element of the project at the GeoCenter Northern Bavaria of the Friedrich Alexander University (FAU) Erlangen Nuremberg is an inventory of all seismic, magnetic, gravimetric and drilling data already available in the Bamberg-Staffelstein-Coburg area and their interpretation with regard to subsurface structure and temperature distribution. In addition, a data pool of the petrographic-petrophysical characteristics of representative rock types of the above mentioned area will be established. The identification of young, hydraulically pathogenic fault systems will be tested by analyzing combined airborne laser scanner data and radon soil gas measurements on selected examples. A subordinate objective of the project is also the targeted identification of information deficits regarding the subsurface structure of NE Bavaria for the targeted planning of further investigations as scheduled within the framework of the Geothermal Alliance Bavaria.

Project description:

Heat supply in the private sector holds considerable potential in terms of primary energy savings and the reduction of greenhouse gas emissions. With a share of around 50 %, heat supply dominates final energy consumption both in Germany and in Bavaria. Energy supply through centrally generating units and distribution through heating networks to buildings and neighborhoods has a very high efficiency potential. In this context, the use of low-temperature heat networks and the integration of heat pumps into such networks represents an innovative approach to reducing pipeline losses and lowering primary energy demand. The project “Energy Efficient Heat Supply – Upper Franconia Initiative” (EWIO) represents a technology transfer between the University of Bayreuth and Upper Franconian SMEs in the field of pipeline construction and energy and building technology. EWIO leads to a better basic understanding of the interplay and mutual influence of the heat supply and distribution system. The technology transfer results in the development and application of efficient system solutions for low-temperature heat networks on renewable basis.

Project description:

Fouling is a huge problem in geothermal industry and causes millions of dollars in damage every year, mainly due to spontaneous breakdown of plants. A low-cost, ultrasonic-based sensor network is being developed in this project for the direct detection and determination of deposits and biofilms for geothermal systems and open cooling circuits. The sensor network is supported by a self-learning predictive-maintenance algorithm, which enables us to predict fouling formation based on the hydrogeochemical simulations and models developed in the project. Therefore we can derive concrete recommendations for system operation. The detachment from fixed maintenance intervals or operation until failure increases the efficiency and resilience of the system and reduces the use of additives.

Project description:

The aim of the “GeoFlex” research project is to analyze the flexibility potential of heat-controlled combined heat and power plants from deep geothermal energy – both from a technical and an economic point of view. In particular, it is examined whether and how deep geothermal energy systems are suitable from a technical point of view for flexible tracking of the residual load and for the provision of control power. In addition, the costs associated with the use of the flexibility potential of deep geothermal energy are determined. These cost structures are then compared to alternative, existing flexibility options.

The project is divided into 5 work packages (WP):

• AP 1: Status Analysis
• WP 2: Technical flexibility properties
• AP 3: Economic analyses
• AP 4: Outlook and options for action
• AP 5: Workshop

Project description:

The deeper subsurface of the Alpine foothills harbors a multitude of natural resources and storage possibilities, so-called geopotentials, which can be used for the sustainable management of green energies and can thus make a significant contribution to the energy transition: the more than 5000 m deep molasse basin along the edges of the Alpine arc are suitable in large areas both for geothermal energy generation and for the storage of weather-dependent green energies, natural gas or CO2. In many places, however, the use of these geopotentials is in direct competition with drinking water supply or oil and gas extraction. The assessment of geopotentials therefore requires a holistic and transnational approach, taking into account possible risks, e.g.

The transnational project GeoMol, which is funded by the Alpine Space Program 2007-2013 as part of the European Territorial Cooperation, brings together partners from Germany, France, Italy, Austria, Slovenia and Switzerland. In the period from September 2012 to June 2015, basic information about the geological structures of the Molasse Basin and the Po Basin will be compiled and evaluated. These are made available to experts for cross-state planning as well as to the public. The 3-dimensional underground information provided by GeoMol is based on uniform evaluation methods and jointly developed criteria and guidelines.

The Department of Hydrogeology at the Technical University of Munich is working on the three-dimensional temperature distribution model in the southern German Molasse Basin on behalf of the Bavarian State Office for the Environment.

Project description:

The project aims at the new development of an instrument for the more efficient planning of near-surface geothermal plants: The over-dimensioning of near-surface geothermal plants such as subsurface heat exchangers is one of the reasons why these plants have not yet been established more widely in the market.

With GeoSurf, instead of rough estimates of the soil conditions, the near-surface geothermal potential (up to a depth of 20 meters) should be determined and visualized in situ with the help of electrophysical measurement methods. The project involves the development of a robust GeoSurf instrument with the appropriate software that maps geoelectric parameters and correlates them to the desired geothermal parameters, such as thermal conductivity. On the basis of the parameters measured in situ, a new model and, derived from this, a simple, user-friendly planning tool for determining the heat exchanger parameters and the area requirements will be developed. The aim of the project is to demonstrate a reduction in the required space by over 30%, which leads to significant cost savings.

Project description:

The aim of the “GRAME” project is to develop the basis for a holistically optimized and sustainable reservoir development for deep geothermal systems in the Bavarian Molasse Basin. With a comprehensive, largely improved knowledge of the subsoil and the associated holistic development scenarios, large-scale projects for power generation of up to 50 MWel and heat generation of up to 400 MWth per exploration field should be made possible. In this project, the hydrothermal reservoir under a major city is to be explored for the first time in a coherent development concept using the large-scale 3D seismic survey Munich South. The seismic data collection and evaluation of the data using the latest methods is intended to optimize the long-term development of geothermal energy and thus the environmentally friendly heat supply of the city of Munich in an already extensively developed district-heating network. This project is intended to lay the foundations and demonstrate in the south of Munich how the potential of hydrothermal geothermal energy in the Bavarian Molasse Basin can be used much better and thus make a significant contribution to CO2 savings in Germany.

Sub work-packages TUM:

• Flexible ORC systems in the medium power class for geothermal applications:
  Promising power plant concepts are being developed in the medium power range for a flexible temperature range. The aim is to have a standardized ORC product that can be adapted to the different local conditions in the Bavarian Molasse Basin.
• Combined  heat and power generation:
  While the demand is regulated by the output of the feed pump in pure heat projects, the power production in CHP systems is limited to the use of excess heat. More or less flexibility can be achieved through a different interconnection or integration of the heat extraction.
• Feedback to existing CHP plants:
  The SWM area is supplied by two large CHP plants. The two conventional power plants on fossil fuels can be operated profitably due to their heat extraction. A heat supply that is mainly based on geothermal energy will have a major impact on the operation of fossil-based cogeneration systems. These effects are estimated using a model.
• Strategies for maintaining security of supply:
  Security of supply for heat and power is essential and must be guaranteed at all times. A certain redundancy in the heat supply can already be achieved through the strategy of several production wells pursued in the GRAME project. New concepts are needed to cover peak loads and power requirements. Mathematical methods should be used for this.

Project description:

The BMW Group is starting a research project on the site of the BMW Dingolfing plant for the innovative intermediate storage of thermal energy at a depth of 500 to 700 meters in what is known as a high-temperature aquifer storage facility. The Chair of Hydrogeology and the Institute of Water Chemistry at TUM provide scientific support for the project. The aim is to set up the first high-temperature groundwater thermal energy storage (HT-ATES) on the BMW site in Dingolfing. The project, which is unique in this form worldwide, makes an important contribution to basic research in the field of heat storage. If successful, new possibilities for decentralized energy production and storage would be opened up, which could lead to significant CO2 savings.

The joint generation of energy and heat through combined heat and power generation is economically and ecologically beneficial. However, with an almost constant electricity demand, the heat consumption is subject to seasonal fluctuations. The concept envisages storing this excess heat in a limestone aquifer from the Upper Jurassic period at a depth of 500 metres. The thermal energy can be called up again in winter if required. To store heat, cold groundwater is first extracted via a production borehole, heated to around 130 degrees Celsius on the surface using the excess heat and then fed back into the deep-lying aquifer via a second borehole. There, the heat is stored in the rock and can be pumped out again in winter in the form of hot water. After the thermal energy has been extracted from the hot water on the surface via heat exchangers, it is returned to the subsoil after it has cooled down. The water cycle is closed and the groundwater does not come into contact with the above-ground works cycle.

This unique and innovative project makes an important contribution to research in the field of heat storage and renewable energies. If successful, the efficiency of decentralized energy production and storage will be increased, thereby reducing overall CO2 production. Proof of the feasibility of such thermal energy storage would be an important milestone on the way to a sustainable energy supply.

Based on the project results, a pilot plant is to be installed and scientifically monitored.

Project description:

The aim of the “IsoMol” research project is to take a holistic view of the flow dynamics in the aquifer of the Upper Jura (Malmaquifer), which is intensively used for hydrothermal geothermal energy production in the Bavarian Molasse Basin. In order to better understand the complex flow systems in deep aquifers, hydrogeological, isotopic and geochemical information is linked and evaluated together.

Previous knowledge suggests the hypothesis that the deep groundwater is made up of several components:

• a recent meteoric freshwater component,
• a glacial meltwater component with depleted signatures in the stable water isotopes,
• an “extreme” formation water component and
• a very old deep water component.

To achieve the goals of the research project, geo- and isotope-chemical investigations at selected locations are evaluated and interpreted in connection with the hydraulic data. As part of a new measurement campaign, special measurement methods are also being used and isotope-chemical parameters that deviate from the standard measurement protocol are being investigated.
