Open call for side events is currently open. Please, contact to propose a side event.

DACH TG "Neue Ansätze im Umfeld der Geothermie"

Time: 14:00 – 15:45

Location: A05

Session Chair: Horst Rüter, HarbourDom GmbH, Germany

The German hard coal industry explored the subsurface in the Ruhrarea, NRW, Germany in extreme detail: over 1300 drillholes up to 1.500m deep, 1600 km seismic 2D-lines, 16 3D-seismic areas. The project KarboEx tries to save this data and use it to gain information about the carbonates of Carboniferous and Devonian age for geothermal use. Results will be presented at the DACH side-event TG “Neue Ansätze im Umfeld der Geothermie” at the EGC2022.

DGE Rollout

Time: 14:00 – 15:45 / 16:15 – 18:00

Location: A06

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 DGE-ROLLOUT 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.

REFLECT : Redefining fluid properties at extreme conditions to optimize future geothermal energy extraction

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.

Women in Geothermal (WING) is an international voluntary, non-profit organization dedicated to advancing the education, professional development and careers of women in geothermal energy. WING-Global currently supervises and supports 34 country teams, which are led by WING ambassadors from the respective country, who implement WING initiatives in their countries. The Germany national team is committed to making geothermal energy more visible, promoting the professional development of women in the geothermal industry and promoting equality between women and men in geothermal energy.

The workshop is also the official kick-off event of the German WING national team, which is made up of 11 members from different disciplines of geothermal energy from science, business and associations. The workshop will be designed in a first part with short contributions from women and men who are committed to the topic of gender equality in geothermal energy and are successfully active in different areas of geothermal energy.

The second part will be an open discussion round on gender aspects in geothermal energy and ways on how to improve gender balance.

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

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.

Joint CROWDTHERMAL and Geothermal-DHC event

Time: 10:35 – 17:30

Location: A05

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 community-financed 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.
