System integration geothermal Binary Power Plant

The main goals of this project are the systematic analysis of the existing research in the fields “geothermal energy” and “low-temperature electricity generation” and the identification of specific topics for knowledge transfer, in particular in the fields “reliable system integration”, “decentralized power supply” and “electrical island mode operation”. Low-temperature power plants can be realized in various sizes, are suitable for the use of different heat sources and have different site-integration concepts depending on technical requirements and non-technical preconditions.

Geothermal District Heat Supply in Berlin

The overall goal of this project is the development of a geothermal heat supply concept for urban areas on the example of a site in the city of Berlin. This should be the particular impulse for an integration of aquifer thermal storage in the Berlin heat supply.

Energy Systems Integration
In the future we will cover a big share of our energy demand with renewable energies. A reliable, stable and affordable energy supply requires, in addition to the obvious grid expansion and storages, the consideration of systemic aspects and flexibility of both the producers and the consumers.

Cooperation in Geothermal energy research Europe-Mexico for development of Enhanced Geothermal Systems and Superhot Geothermal Systems
The GEMex project is a joint effort of a European consortium (24 partners) with a corresponding consortium from Mexico (9 partners). GEMex focusses on resource assessment and characterization based on the combination of novel and conventional technologies at two geothermal systems in the Mexican Volcanic Belt. Concepts for site development will evolve from the project. GEMex is coordinated by GFZ.
