Shallow Geothermal Energy

Intelligent Heating and Cooling

Round-the-clock, all-season, unlimited energy for heating and cooling? And what is more - in your own country, meaning independent of global crises and economic cycles. And last but not least, with economic advantages compared to conventional sources of energy. What seems fictional at a first sight can be realized by the use of shallow geothermal energy. The environmental consultants and engineers of HPC will answer your questions and support you during implementation of your “energizing” project. Multiple dwelling, apartment buildings or building groups, public buildings, administration buildings, hospitals and schools  or commercial and service facilities of all kinds – shallow geothermal energy creates a comfortable indoor climate with economic advantages and – as a free offer – with environmental benefits.

HPC will support your project with comprehensive and competent advice.

Depth  Geothermal Energy

Future-oriented development and utilization of geothermal energy or “the energy stored in the form of heat beneath the surface of the solid earth"

The depth geothermal energy offers the greatest potential of renewable energies. Regardless of weather, climate, time of day and from fossil or other conventional fuels their reservoir that is virtually inexhaustible is everywhere and always available. Due to the possibility of replacement of fossil and other conventional fuels the depth geothermal energy offers large security of supply over literally geological periods. Negative side effects such as CO₂-emissions can be reduced. The fossil fuels can be used more significantly hereby. Among the renewable energies the geothermal energy can make a stable contribution to secure the base load supply.

The increase in mountain temperature by on average about 3°C per 100 m of depth allows depending on the geological site conditions the utilization of geothermal energy by means of adequate depth drillings. The following technologies are currently applied:

Hydrothermal systems with low heat content:

• Heat from groundwater with temperatures of up to about 100°C by means of production wells and re-injection into the subsoil by means of an injection drilling (duplicate)

Hydrothermal systems with high heat content

• Use of temperatures of about 180°C up to more than 500°C in volcanically active areas

Petrothermal systems:

• Hot dry rock process
• Hot fractured rock method
• EGS (enhanced geothermal systems)
• Depth geothermal probe

These petrothermal uses are based on the principle of a heat exchanger: Water is introduced into the rocks outcropped in great depths by means of drillings and recovered after heating for energy production.

The extensive experience at HPC with depth drillings in the development of thermal water and natural carbon dioxide as well as the cooperation with specialized companies, government agencies, laboratories and other service companies is the basis for our services in the field of depth geothermal energy:

• Preliminary study (pre-feasibility study, depth of the water reservoir, temperature estimate, yield)
• Feasibility study with site-specific evaluation of the geology and the geothermal potential
• approval process (mining law approval process, operating plans for exploration and recovery of thermal energy, delimitation of permission and production fields, site preservation, protection of drinking water and mineral springs)
• Site-specific exploration of geothermal energy, possibly with geophysical exploration methods (2-D-seismic, 3-D-seismic) and selection of the appropriate use of the depth geothermal energy adapted to the site
• Technical and geological planning and design of the depth drillings, tests (pumping tests, stimulation tests, commissioning, geothermal response test) cost estimation and tendering of the drillings, design and tendering of lines
• Planning of the drilling sites according to the specific site requirements and their reclamation
• Project management, construction management, evaluation of the measuring results (pumping tests, geophysical measurements)
