HYDROSION

What HYDROSION does

HYDROSION GmbH is a privately held German hydrochemical consulting firm founded in 2012 by Dr. Jochen Schneider and headquartered in Gräfelfing near Munich. The firm provides specialized groundwater and deep-groundwater analysis services for geothermal operators, energy utilities, federal agencies, and municipalities, with a core methodology built on hydrochemical and isotope analysis (both stable and radioactive) of geothermal fluids. Its integrated service portfolio comprises six modules: Fluid-Monitoring im Betrieb, Grundwasser-Screening, Betriebssicherheit von Geothermieanlagen, Reservoircharakterisierung, Geothermie und Strahlenschutz (NORM monitoring), and Geothermische Lithiumextraktion.

The firm operates a project-based B2B consulting model, deploying hydrochemical sampling, isotope investigation, and radiochemical monitoring with subcontracted laboratory analytics. Customers include major German energy and geothermal players — EnBW, Bundesanstalt für Geowissenschaften und Rohstoffe (BGR), GeoHardt, Geothermische Kraftwerksgesellschaft Traunreut, Erdwärme Riehen, and Wärmewerk Wörth — together with federally funded research consortia (BMWK/BMBF). HYDROSION generates revenue through professional service fees on consulting engagements and managed-service participation in government-funded research projects such as UnLimited, Li+Fluids, and the EU-funded LiCORNE.

The team is small and stable: Dr. Schneider as Managing Director alongside geologists Utz Kolvenbach and Anne Mutzek. Since 2020 the firm has deliberately extended its scope into direct lithium extraction (DLE) from geothermal brines, giving it positioning in Germany's emerging climate-neutral raw materials strategy. No external investors, parent companies, or public financial disclosures were identified.

Core offering

HYDROSION is a consulting firm offering hydrochemical services for groundwater and deep water investigations, focused on geothermal energy systems. It delivers six service modules covering fluid monitoring during plant operation, groundwater screening for identifying geothermal upwelling pathways, operational safety (corrosion and scaling), reservoir characterization via isotope analysis, radiochemical monitoring and radiation protection (NORM), and consulting for geothermal lithium extraction. Clients include geothermal plant operators, energy utilities (e.g., EnBW), federal agencies (e.g., BGR), and municipal utilities.

Product overview

HYDROSION is a consulting company offering hydrochemical services for groundwater and deep water investigations, with a focus on geothermal and groundwater systems. The company provides six integrated service modules: Fluid-Monitoring im Betrieb (fluid monitoring during plant operation), Grundwasser-Screening (groundwater screening), Geothermie und Strahlenschutz (geothermal and radiation protection), Betriebssicherheit von Geothermieanlagen (operational safety of geothermal plants), Reservoircharakterisierung (reservoir characterization), and Geothermische Lithiumextraktion (geothermal lithium extraction). These services work together to support the entire lifecycle of geothermal operations, from exploration and reservoir characterization to operational monitoring and lithium co-production.

Products and services

• Fluid-Monitoring im Betrieb (Operational Fluid Monitoring) Recurring and targeted measurement of selected parameters to generate information for optimized operation management of geothermal plants. Includes conception and implementation of site-specific monitoring programs, sampling, sample handling, and independent analytics for water, gas, and solids, leveraging the chemical inventory of produced geothermal waters.
• Grundwasser-Screening (Groundwater Screening) Combined exploration approach enabling identification of potential upwelling paths of geothermal deep waters, particularly for the Upper Rhine Graben. Includes data acquisition study design, multi-stage investigation program conception, groundwater sampling with remote-controlled equipment, sample handling, and GIS data integration.
• Betriebssicherheit von Geothermieanlagen (Operational Safety of Geothermal Plants) Operational safety services addressing corrosion and scaling in geothermal plants. Includes site-specific corrosion investigations, chemical composition analysis of scalings, non-destructive in-situ measurement of corrosion and scaling, condition monitoring during the operating phase, and derivation of prevention strategies through inhibition.
• Reservoircharakterisierung (Reservoir Characterization) Reservoir characterization through stable and unstable isotope investigations for geothermal reservoir engineering. Includes complete hydrochemical analysis of geothermal waters including gas phase and specific isotope systems, mineralogical and radiochemical analysis of drill cuttings, water-rock interaction modeling, dating methods, and integrated determination of site-specific reservoir parameters.
• Geothermie und Strahlenschutz (Geothermal and Radiation Protection) Radiochemical monitoring services during plant operation, including radiochemical investigation of mineral deposits (NORM), site-specific investigation of mobilization and deposition processes of naturally occurring radionuclides, consultation on disposal of contaminated materials, and estimation of radiation exposure of employees.
• Geothermische Lithiumextraktion (Geothermal Lithium Extraction) Consulting services for lithium extraction from geothermal deep waters, including test setup conception, test planning, test execution, fluid monitoring for performance determination, and monitoring of potential hazardous substances such as heavy metals and natural radionuclides.
