Information on Geothermal Energy and Geo-HEP Systems
Geology, Groundwater, Load Profiles
Geothermal systems utilize the thermal properties of the subsurface in various ways.
Which solution is suitable for a project depends on far more than just the available space or the desired heating and cooling capacity.
Geology, groundwater, load profiles, required temperature levels, existing system infrastructure, and permitting requirements all influence the planning process, as does the question of whether the system should primarily provide heating, cooling, or a combination of both.
In our knowledge section, we explain the most important fundamentals, compare different systems, and answer typical questions related to planning and practical application.
A Comparison of Geothermal Systems
Ground collectors, conventional geothermal probes, energy piles, groundwater systems, deep geothermal systems, and geothermal hydroelectric power (Geo-HEP) employ different technical approaches. Our comparison page categorizes these systems and highlights the specific applications where their respective strengths are particularly relevant.
How does the Geo-HEP high-performance energy pile work?
The high-performance energy pile combines heat exchange with the ground and an integrated thermal storage mass to buffer short-term load peaks. We’ll explain how it works using a single pile as an example—from the absorption of thermal energy to heat exchange with the surrounding ground.
Understanding Passive Cooling Simply
Under suitable site and operating conditions, excess heat from buildings, machinery, or technical processes can be transferred to the ground via a geothermal system without the need for a conventional chiller to run continuously. This makes passive cooling particularly attractive when annual operating hours are high.
Geology and Groundwater—Why Location Is Critical
Not every geological situation is the same. Thermal conductivity, stratification, drillability, and groundwater conditions influence the achievable performance and the design of a geothermal power system. Moving groundwater, for example, can aid heat transfer underground.
Combining Heat Pumps and Geothermal Energy
In heating mode, the Geo-HEP system can serve as a heat source for a heat pump. The relatively constant underground temperatures throughout the year create favorable conditions for heat supply.
What does thermal load buffering mean?
The water mass integrated into the high-performance energy pile can absorb thermal energy for short periods of time. This allows peak loads within the system to be buffered before the heat is transferred to the ground. This function should be distinguished from targeted, long-term seasonal storage.
