To control scaling and corrosion in geothermal plants, inhibitors are increasingly preferred as a solution. However, this raises questions which inhibitor is suitable or which dosage is sufficient. But also the question of suitable analysis methods for the investigation of the effect and interaction with parts of the plant, thermal water and rocks becomes relevant in this context. The workshop will present and discuss current work and solutions.

Feed pumps of geothermal plants are the heart of energy production. They bring the deep groundwater to the surface for cooling. However, especially in high-temperature systems (> 100 ° C) repeatedly trouble and problems occur. The workshop "Use of geothermal feed pumps" has been part of the Praxisforum Geothermie.Bayern in recent years. This year it will present the latest developments.

Geothermal project development has several risky components, the most important one being the resource risk. This concerns mainly deep geothermal projects, but some shallow geothermal open systems could also be included in this category of projects. Beyond exploration, the bankability of a geothermal project is threatened by this geological risk.GEORISK project works to establish risk insurance all over Europe and in some key target third countries to cover the exploration phase and the first drilling (test). It means activities to be funded before financial institutions and IPP funding the confirmation drilling and surface systems. It appears clear that a risk mitigation scheme must be designed according to the market maturity of the sector.This workshop aims at identifying the conditions for a transition in the insurance schemes, according to market maturity for geothermal projects. This will notably include a presentation of the first results of the GEORISK project. The workshop aims to create a discussion between the project partners, the members of the Advisory committee and the other participants to the workshop.

Climate change is proceeding, but countermeasures are being introduced only hesitantly. Deep geothermal energy can play an important role in the urgently needed acceleration of the energy transition. Geothermal is a technology that can generate both electricity and heat. With coupled use, it reveals a negative CO2 balance. The keynote addresses the need for action and opportunities.

The degression listed in the EEG threatens to slow down the further development of geothermal energy production. From 2021, five percent of the degression on EEG remuneration is planned. Here, changes and adjustments are needed to avoid the loss of geothermal energy. For since the introduction of the EEG, the use of geothermal heat has multiplied, that is, the EEG indirectly promotes geothermal heat use. And with the EEG remuneration of electricity, the heat production costs from the same plant are also unrivaled.The forum discusses with experts the development of the EEG and what the future of geothermal energy production can look like.

An vielen geothermischen Anlagen ist eine geringe seismische Aktivität unterhalb der Spürbarkeitsschwelle festzustellen. In Bayern wird dies wird von den Betreibern von Geothermie-Anlagen und dem Bayerischen Erdbebendienst kontrolliert. Aber auch andere Bundesländer verfügen über Messnetzwerke zur Überwachung von seismischen Aktivitäten. Verschiedene Maßnahmen sind vorgesehen, damit es zu keinen größeren seismischen Ereignissen kommt. Im Rahmen des Forums werden diese vorgestellt.

After reservoir development, the test works confirm the success or failure of a project. In case of success, however, the question remains as to how reproducible the results are in the ongoing operation of the plant. This will be discussed on the basis of various talks from the practical experience of numerous projects.

In addition to the metropolitan area of Munich, a second geothermal hot spot in Bavaria has developed east of the Inn Valley. After the first projects in Waldkraiburg, Kirchweidach and Traunreut, Garching (Alz) leads the second development phase. The forum gives an overview of the current projects and developments.

The Praxisforum Geothermie.Bayern has dedicated this year's focus to the future-proof geothermal heat supply. This will also be reflected in the GeoTHOUR, which is sponsored be Turboden. As in the recent years, we will visit and introduce two geothermal plants, in the morning an electricity and heat producing plant, which is introduced by Turboden and in the afternoon the heat plant of Poing. You will receive information about the characteristics of the plant, its operation and the development of the geothermal resource.The Turboden-GeoTHOUR comprises catering during the trip and the transportation by bus from Munich Main station and back.
