GeoTHERM

When planning your visit, knowing the GeoTHERM Offenburg dates is essential for scheduling meetings with decision‑makers in the geothermal energy sector.

Professional buyers in this industry rarely make decisions based on surface‑level technology alone. Subsurface risk mitigation, project bankability, and long‑term operational reliability often carry as much weight as technical specifications. GeoTHERM Offenburg provides a professional environment where project developers, geoscientists, and engineering specialists can examine technologies, compare solutions, and assess whether a supplier fits the technical and commercial requirements of the geothermal energy sector.

Why Visit GeoTHERM Offenburg?

For professional visitors, GeoTHERM Offenburg offers a concentrated setting to compare geothermal technologies, discover emerging innovations, evaluate suppliers, and follow developments across the European geothermal industry within one event.

The world’s largest geothermal expo and congress attracts project developers, drilling contractors, geoscientists, municipal utility planners, and policy specialists from across Europe.

The exhibition covers the entire geothermal value chain from exploration and drilling to plant operation and energy distribution. For buyers and technical evaluators, the event provides an opportunity to assess new solutions, compare project references, and evaluate supplier reliability for capital‑intensive geothermal projects.

Exhibition Background & Industry Context

GeoTHERM has been held annually in Offenburg since 2008 and has evolved into the world’s largest geothermal expo and congress. The fair brings together international experts, companies, and decision‑makers from the shallow and deep geothermal sectors, with two parallel congresses covering both application areas. The next edition will celebrate its 20th anniversary on 25 and 26 February 2027 at Messe Offenburg‑Ortenau, with opening hours from 9:00 a.m. to 5:30 p.m. on Thursday and 9:00 a.m. to 3:30 p.m. on Friday.

In 2026, GeoTHERM brought together 302 exhibitors and 8,688 trade visitors, alongside two parallel congresses covering shallow and deep geothermal energy. The 2027 edition will also highlight sector coupling and potential synergies between geothermal energy and the oil, gas, and mining industries. The fair’s focus on subsurface risk mitigation, reservoir productivity, and decades‑long operational integrity reflects the industry’s shift toward collaborative, long‑term partnerships where success is measured over decades, not quarters.

Is This Trade Fair Right for You?

Relevance depends on your role within the geothermal value chain and whether your objectives involve sourcing technologies, identifying project partners, or understanding market trends in the European geothermal sector.

Ideal For

• Geothermal project developers and operators
• Drilling contractors and subsurface engineering specialists
• Geoscientists and reservoir engineers
• Municipal utility planners and district heating specialists
• Providers of drilling technology, downhole tools, and geothermal equipment
• Companies offering geophysical surveying, reservoir modeling, and monitoring systems
• Policy specialists and regulatory experts
• Investors and financial institutions evaluating geothermal projects

These professionals can assess technology solutions, compare project references, and examine how different suppliers address subsurface risk mitigation, project bankability, and long‑term operational reliability.

May Be Less Relevant For

GeoTHERM may be less relevant for visitors focused on general renewable‑energy products without a specific connection to geothermal applications. Its specialised technical programme is primarily relevant to professionals involved in geothermal exploration, drilling, heating systems, project development, plant operation, research, investment, or related services.

Industries & Business Areas Represented

• Shallow Geothermal — ground‑source heat pumps, borehole heat exchangers, system design
• Deep Geothermal — exploration, drilling, reservoir engineering, power generation, district heating
• Drilling Technology — drilling rigs, downhole tools, casing, cementing, and completion
• Geophysics & Surveying — seismic surveys, logging, monitoring, and subsurface characterisation
• Reservoir Engineering — modeling, simulation, stimulation, and production optimisation
• Plant Technology — pumps, heat exchangers, ORC systems, and materials for corrosive environments
• Monitoring & Digitalisation — sensor systems, data analytics, digital twins, and AI for geothermal
• Services — consulting, project management, financing, and regulatory advisory

These business areas are connected by the operational and financial requirements of geothermal projects, where subsurface risk mitigation, project bankability, and long‑term operational reliability are as important as individual technologies.

• Materials for high‑temperature, corrosive geothermal environments
• Digital solutions for reservoir simulation and plant optimisation
• Consulting, project management, and financing services

Business Opportunities

• Compare geothermal technologies against subsurface risk mitigation, project bankability, and operational reliability
• Assess new innovations and emerging solutions for shallow and deep geothermal applications
• Identify potential suppliers, technology partners, and project developers for geothermal projects
• Evaluate approaches to exploration, drilling, reservoir engineering, and plant operation
• Examine how different suppliers address geological uncertainty, regulatory compliance, and long‑term performance
• Network with project developers, geoscientists, drilling contractors, and industry professionals

How to Prepare for a Productive Visit

Before attending GeoTHERM Offenburg, careful planning can significantly improve the value of your visit:

• Define your strategic priorities: Identify whether your focus is on shallow geothermal, deep geothermal, drilling technology, or reservoir engineering.
• Prepare questions about project references and risk mitigation: For potential partners, ask about successful reference projects, subsurface risk management, and long‑term operational performance.
• Divide the exhibitor landscape by your priorities: Before the event, group exhibitors by key technology areas — exploration, drilling, plant technology, monitoring, and services — to structure your visit efficiently. The fair takes place on 25 and 26 February 2027 at Messe Offenburg‑Ortenau.
• For drilling and subsurface technology: Examine performance in challenging geological conditions, materials durability, and project references.
• For plant and monitoring technology: Assess reliability, efficiency, and long‑term operational data.
• For consulting and services: Evaluate sector expertise, project experience, and regulatory knowledge.
• Plan meetings with potential partners: The event provides an opportunity to coordinate with technology providers, project developers, and industry professionals in one location.

Exhibitor Perspective

Exhibitors at GeoTHERM range from international drilling technology providers and geophysical survey companies to plant manufacturers, monitoring specialists, and service providers. Visitors evaluating potential partners should look beyond individual products to understand project references, subsurface risk mitigation capability, and long‑term operational reliability.

The integrated congress adds an important technical and scientific dimension to the exhibition, allowing visitors to compare commercial solutions with current research, project experience, regulatory developments, and practical applications across shallow and deep geothermal energy.
