The ITHERLAB project investigates the influence of in-situ (present state in the geological subsurface) pressure and
temperature on rock thermal properties (thermal conductivity and thermal diffusivity) as one of the essential thermal
properties in the evaluation of the Earth thermal field. The ITHERLAB project will establish mathematic formulations for p/T
dependence of both parameters and demonstrate whether micro-structural effects affect these relations for different rock
types. For that purpose, an innovative laboratory device will be developed and pilot-tested allowing for dry and saturated
rocks measurements of thermal conductivity and thermal diffusivity at pressures and temperatures that are simultaneously
raised to values up to 200 MPa and 200°C, respectively. These are the conditions for depths (to approx. 7 km), which are of
interest in the use of Earth resources (such as geothermal energy, hydro-carbons, storage of energy or waste). Currently, no
laboratory standard procedure exists for this task. Precise knowledge of reliable in-situ thermal rock properties and derived
thermal parameters (e.g. heat-flow density) is in-dispensable for understanding the Earth’s subsurface thermal structure and
heat budget. Heat mainly drives geody-namic processes (e.g. mantle convection, plate tectonics). Practical implications for
the society are arising for exam-ple from the extraction of the Earth’s heat for heating purposes or electricity generation and
from the subsurface storage of heat to compensate different seasonal energy demands - techniques that can help to secure
and diversify Europe’s energy supply. Moreover, knowledge and methods provided by the ITHERLAB project are paramount
for the planning, management and realization of any scientific and industrial subsurface application, which is affected
technologically or economically by the subsurface thermal field (temperature and heat budget).
