I am very pleased that this year’s European Geothermal Congress will take place in Germany, and that we may welcome you together with the European Geothermal Council (EGEC) here in Berlin.

The technical solutions for the future of energy supply are available and the interest in geothermal energy has increased significantly in recent months. It is clear to many stakeholders in the energy industry and public administration as well as to policy makers that the expansion of shallow, medium-deep and deep geothermal energy must be accelerated significantly and that great efforts are required to achieve this.

Fighting global climate change and creating European energy sovereignty requires massive investments in the development of renewable energies. In this context Geothermal energy plays a vital role in Germany, especially with heat transition. Geothermal heating systems offer security of supply and strengthen our independence from fossil fuels. Geothermal energy has a dispatchable generation capacity and is available to us 24/7. Heating and cooling systems convert renewable electricity into thermal energy in a highly efficient way. Geothermal systems take up very little space and are almost invisible because most of the systems are installed underground. The use of Geothermal keeps heating stable in price. Moreover, we will be able to extract rare raw materials such as lithium from geothermal deep water in a climate-neutral way.

Geothermal energy can contribute to a secure, economical and eco-friendly energy supply for the people of Europe. For the rapid expansion of geothermal energy use we need to have a suitable legal framework. This includes streamlined approval procedures, sensible funding instruments and a well-positioned research and development landscape.

Applied research and development for geothermal energy will be the focus of this year’s European Geothermal Congress (EGC 2022). Efficient exploration and development of the geothermal resource will continue to improve as it scales up in the foreseeable future. We will meet here in Berlin in order to present and discuss the necessary inventions and innovations.

As President of the German Geothermal Association (Bundesverband Geothermie e.V.) and as Chief Technical Officer of Stadtwerke München GmbH (Munich City Utilities), I cordially invite you to Berlin. You can expect days full of insightful discussions and to learn about the latest state of science.

Sincerely yours

Dear Ladies and Gentlemen, this edition of the European Geothermal Congress is being held in a country that has made geothermal a priority of its energy transition. Germany has been experiencing significant market growth in recent years, notably in the deep geothermal heating sector. Only the city of Munich itself has allocated 1 billion euros for future geothermal district heating development. This year’s congress is taking place in a critical moment for Europe. In 2022, a devastating war returned to the European continent and brought again into picture the issue of energy supply security to the centre of European energy policy debates. The inflation is again a major characteristic of the European economy, driven by the explosion of hydrocarbon prices over the past 12 months. In reaction to these geopolitical and macroeconomic disruption, the energy transition is back at the highest level, with more importance than ever. As an industry, we are collectively grappling with the changing paradigm of the year 2022 and, therefore, it is ever more important to understand how the geothermal sector has progressed and evolved over the past year, whether it recovered from the COVID-19 disruptions, and whether we are ready to face today’s and tomorrow’s challenges.Recently we have observed a return to growth for the geothermal heating and cooling industry, after several years of slow developments and negative policy signals. For district heating, we are starting to see that the steadily growing interest for geothermal projects is now becoming tangible with more than 14 new systems commissioned in 9 different countries! Elsewhere, a new wave of innovative technologies brings a new wind of hope for the geothermal electricity industry which has learned from the failure to scale up the EGS technology at the speed we hoped. Lithium is a particularly powerful buzzword, bringing the European Union and national governments to look closely at the potential of co-production of geothermal power, heating and lithium.

GEOTHERMAL ENERGY is THE ANSWER to the energy challenges that Europe is facing today. Geothermal energy brings security of supply, flexibility and resilience to the energy system.

We need to acknowledge that the energy transition needs planning to ensure a successful phasing out of fossil fuels and the affirmation of new business models driving further geothermal deployment. Only when industry, policy makers, science and communities come together, can we develop the instruments for a more sustainable future. This is what the European Geothermal Congress aims to accomplish.

On behalf of the Scientific and Organising Committee, I would like to take this opportunity to thank our sponsors, partners, and contributors, without whom the congress would not be possible. I would also like to extend a warm welcome to all of you joining us this week and wish you a successful and fruitful event.

1. REFLECT final conference: Redefining fluid properties at extreme conditions to optimize future geothermal energy extraction

Date: 19.10.2022

Time: 11:00 – 12:45 / 14:30 – 16:15

Location: A06

Session Chair: Katrin Kieling, Helmholtz-Centre Potsdam GFZ, Germany

The one problem plaguing almost all deep geothermal operations in the world is related to the chemistry of the geothermal fluids. In order to maximize both the operational efficiency and economic returns of geothermal power plants, it is vital that these systems work well for long periods without requiring significant maintenance. Key to this is preventing or controlling deleterious physical and chemical reactions such as degassing and mineral precipitation that result in corrosion and scaling.

The Horizon2020 REFLECT project, funded by the European Commission, addresses the challenge of determining geothermal fluid properties at in-situ geothermal conditions, i.e., extremely hot or extremely saline fluids. The project has acquired new chemical, physical and microbiological data from sampling of natural fluids and new thermodynamic and kinetic reaction data from experiments in the lab. These data were implemented in predictive models to determine fluid reactions at extreme conditions, and into a comprehensive European Fluid Atlas. REFLECT researchers also develop a downhole sampler for high-temperature geothermal wells. The results presented during this final project event will enable operators to significantly increase technology performance and reduce maintenance costs or downtimes and, thus, reduce operational costs and increase the number of economically viable geothermal projects.

North-West Europe (NWE) has to reduce CO2 emissions. One major source for the latter is the production of electricity and heat by burning fossil fuels. Replacing this process through the implementation of deep geothermal energy (DGE) could significantly aid to the reduction of CO2 emissions and hence support a sustainable energy generation. However, the exploration of hydrothermal DGE targets in most NWE regions requires comprehensive investigation and specific geologic and engineering expertise considering the generally complex setting including strongly faulted and folded horizons of highly permeable carbonate rocks, in the border area consisting of Germany, France, the Netherlands and Belgium. It is the objective of DGE-ROLLOUT to promote the use of DGE and also to reduce CO2 emissions through the initiation and optimization of particular pilot projects. This is aimed to be achieved using a multi-disciplinary approach including the improvement of the current insufficient data situation, the compilation and development of innovative decision and exploration strategies, as well as the optimization of existing DGE manifestations. Therefore, the DGE-ROLLOUT project comprises three work packages: Mapping and networking (WP T1), Decision and exploration support (WP T2) and Testing for production optimization (WP T3).

WP T1 seeks to provide a reconciled and common knowledge baseline for the DGE market development in the project area, including the preparation of a transnationally harmonised depth and thickness map of the currently targeted Lower Carboniferous carbonate reservoir rocks. WP T2 intends to fill existing information gaps by acquiring transnational 2D seismic surveys, conducting drilling operations, reprocessing vintage 2D seismic data, and producing a variety of subsurface 2D and 3D models. WP T3 aims to increase the efficiency of existing geothermal systems, and to implement new or improved production techniques in the fields of reservoir behaviour, cascading systems and thermal energy storage.

Besides the Geological Survey of North Rhine-Westphalia as the lead partner, the DGEROLLOUT project partners include the national geological surveys of Belgium, France


and the Netherlands, as well as industry partners (DMT GmbH & Co. KG; Energie Beheer Nederland B.V.; RWE Power AG) and research institutions (Fraunhofer Institution for Energy Infrastructures and Geothermal Systems; Technical University Darmstadt; Flemish Institute for Technological Research).

Our Side Event in the course of the European Geothermal Congress 2022 will provide an overview of the work that has been undertaken throughout the DGE-ROLLOUT project’s lifetime (Oct 2018 – Oct 2023), present major results that have been achieved, and give an outline of the approach to foster the development of DGE for both small- and large-scale infrastructures. Our Side Event will be subdivided into four thematic blocks comprising 1) Mapping the DGE Potential of North-West Europe, 2) Supporting DGE Exploration, 3) DGE Case Studies and 4) Upscaling DGE for Industry.

6. Soil2Heat “Very shallow geothermal energy –an economic solution for a sustainable energy transition”

Date: 20.10.2022

Time: 10:30 – 15:45

Location: B04


How do we manage a sustainable energy transition on short term?

The building sector is the largest single energy consumer in Europe, absorbing 40% of final energy, and about 75% of buildings are energy inefficient. Geothermal Heating and Cooling are highly promising in order to cover future sustainable heating and cooling demands at low costs, low emissions and high level of efficiency. Very shallow geothermal systems use the energy just below the earth’s surface. These systems distinguish by easy handling and low-cost implementation. In between these systems have been established as a reliable and mature alternative to other geothermal sources. In this side-event the potential and performance of very shallow geothermal energy will be demonstrated for single residential buildings up to grid connected district heating and cooling (DHC) networks. Also typical challenges will be tackled by presenting solutions for integration in urban areas or measures to increase the performance. An open discussion about the state and perspective of very shallow geothermal energy will take place in a dedicated panel session.

About the organizers:

Soil2heat is a German-Austrian cooperation network funded in the ZIM programme of the German Federal Ministry for Economic Affairs and Climate Action. We develop and provide innovative single house to grid-connected district heating and cooling solutions. As geothermal source, very shallow geothermal collector systems and their special forms (e.g. trench collectors, heat baskets) with maximum installation depth of 5 m are used. The 30 partners cover the entire value chain from research via planning and industry to energy suppliers and municipal utilities. The network is coordinated by the Geozentrum Nordbayern of the Friedrich-Alexander University of Erlangen-Nuremberg. For more information please visit

Time: 10:35 – 17:30

Location: A05

First Geothermal District Heating and Cooling Day event: “Bringing Geothermal heating and cooling networks closer to the people”

About the event

The Geothermal District Heating and Cooling Day intends to connect science and society by presenting recent developments and prospects, supporting the interlinking of stakeholders across Europe and jointly address present challenges and barriers for the deployment of geothermal energy supported heating and cooling networks in Europe. Due to the special opportunity given by the European Geothermal Congress 2022, the first Geothermal District Heating and Cooling Day event will have a stronger focus on interconnecting researchers related to geothermal energy use in heating and cooling networks from a trans-disciplinary perspective.

During the afternoon session, the EU project CROWDTHERMAL will celebrate its final conference. During the Conference the project team will present a set of reports, addressing social, environmental, financial, and risk mitigation aspects of communityfinanced geothermal projects.

About the organizers

The mission of the Horizon 2020 funded CROWDTHERMAL project is to empower the European public to directly participate in the development of geothermal projects, with the help of alternative financing schemes and social engagement tools. CROWDTHERMAL aims to initiate a new form of public dialogue, during which it will be possible to jointly tackle concerns and increase interest in geothermal energy. The aim is to take public engagement to a new level, empowering citizens to directly participate in the development of geothermal projects with the help of alternative financing, such as crowdfunding. This will only be possible if public trust can be gained, and the transparency around geothermal projects (and their social and environmental impacts) can be maximised.

For more information please visit:

The EU COST Action CA18219 Geothermal-DHC represents a network addressing the integration of geothermal energy into decarbonized heating and cooling networks addressing the full range of geothermal technologies. Geothermal-DHC investigates concepts related to shallow geothermal in local heating and cooling networks (“5th generation networks”) towards direct geothermal energy use for district heating supply. Geothermal-DHC offers an inclusive European network currently covering more than 100 researchers and non-scientific stakeholders from around 40 countries around the world.

Helmholtz Centre Potsdam – German Research Centre for Geosciences GFZ Potsdam has a highly developed, interdisciplinary laboratory infrastructure that addresses various scientific issues in basic and applied research. Sophisticated apparatus and equipment are designed for a wide range of applications. The Thermal Petrophysics Lab produces data of thermal properties of rocks, minerals, geo-materials and cement. The Laboratories for Geothermal Rock and Fluid Physics allow to characterize and parameterize physical rock and fluid properties and a Mechanical Testing System (MTS) can analyze hydraulic and mechanical rock properties of geo-materials – all under simulated in situ conditions of pressure and temperature of up to 4 to 10 km of depths. The Fluid Lab offers instruments for experiments and measurement facilities designed to characterize, analyze, and monitor processes of geothermal fluids. Another focus is on the kinetics of gas hydrate formation and decomposition and their influence on the physical properties of sediments. A guided tour presents the scientific work in the laboratories, which are also opened to international guest scientists.

12:00 – 13:00 Lunch at GFZ

13:00 – 15:00 Potsdam on the way to geothermal heat supply (EWP)

Deep geothermal energy is to contribute to the decarbonization of Potsdam’s district heating in the future. By 2050, the state capital wants to reduce its CO2 emissions by 95 percent. The local utility Energie und Wasser Potsdam (EWP) produces a large part of the energy used in the city and wants to set the course for geothermal energy with a pilot project to supply a residential area in the centre of Potsdam. The project will be presented during an on-site visit to the drilling site.

Excursion “Experience geothermal energy – best practice near-surface geothermal energy”

Friday, 21/Oct/2022

Time: 9:00 - 15:00

As part of the excursion “Experience geothermal energy – best practice near-surface geothermal energy”, current construction sites and buildings already in operation in the Berlin area will be visited. The technology for exploiting geothermal energy is primarily based on geothermal sensors.

At the beginning, the excursion participants will receive an introduction to the projects and special features of the German geothermal energy market as well as insights into current developments and trends.

During the 4- to 6-hour bus excursion, there will be sufficient time for participants to


discuss current issues and debate the European geothermal market. The excursion will be led by Dipl.-Geol. Rüdiger Grimm and Dipl.-Ing. Christian Lumm from geoENERGIE Konzept GmbH, a company of the ENGIE Group. Protective equipment (helmets and safety waistcoats) will be provided, participants are required to bring sturdy footwear.

Excursion “Geothermal energy use at the Humboldt Forum Berlin – complex underground and complex energy concept”

Friday, 21/Oct/2022

Time: 10:00 - 12:00

The Humboldt Forum in Berlin-Mitte has been hosting cultural exhibitions and events since 2020. Architecturally, it is modelled on the former Berlin City Palace, but in terms of energy it is more innovative and relies heavily on geothermal energy in conjunction with borehole heat exchangers and large heat pumps for heating and cooling. In implementing the system, which was planned by Geothermie Neubrandenburg, the use of geothermal energy had to be harmonised with other forms of energy and a complex underground infrastructure. The energy concept of the Humboldt Forum Berlin will be presented in an excursion.

Excursion “Field trip to the Muschelkalk quarry in Ruedersdorf, East of Berlin”

Friday, 21/Oct/2022

Time: 9:00 - 15:00

This field trip is a journey into an 245-Mio-year-old ocean led by experienced geologists in cooperation with the Museumspark Ruedersdorf. During the Triassic, carbonate muds were deposited in a shallow-marine environment. Ruedersdorf (E of Berlin) is located in the North German Basin, part of the Central European Basin System. The basin consists of several km-thick sedimentary Quaternary to Phanerozoic strata. Thick salt deposits were formed during the Permian Zechstein stage. With the lower density of rock salt compared to the overlying strata, the salt became mobile and formed salt diapirs in the subsurface.

One regional example is the Ruedersdorf structure, where the Triassic Muschelkalk Formation has been exposed at the surface and constantly mined for building stones and cement. The halokinesis (salt tectonics) lead to the formation of a trap structure for subsurface strategical natural gas storage.

Current research by the GFZ Potsdam involves using the Muschelkalk Formation for geological subsurface energy storage (ATES IQ). Furthermore, this formation hosts large hydrothermal geoenergy potential in the North German Basin.

During this field trip, sedimentological features, typical Mesozoic fossils, and the strontium mineral coelestine can be observed and collected. Health & Safety involves
