Session Abstract

How do we manage a sustainable energy transition on short term?

The building sector is the largest single energy consumer in Europe, absorbing 40% of final energy, and about 75% of buildings are energy inefficient. Geothermal Heating and Cooling are highly promising in order to cover future sustainable heating and cooling demands at low costs, low emissions and high level of efficiency. Very shallow geothermal systems use the energy just below the earth's surface. These systems distinguish by easy handling and low cost implementation. In between these systems have been established as a reliable and mature alternative to other geothermal sources.

In this side-event the potential and performance of very shallow geothermal energy will be demonstrated for single residential buildings up to grid connected district heating and cooling (DHC) networks. Also typical challenges will be tackled by presenting solutions for integration in urban areas or measures to increase the performance. An open discussion about the state and perspective of very shallow geothermal energy will take place in a dedicated panel session.

About the organizers

Soil2heat is a German-Austrian cooperation network funded in the ZIM programme of the German Federal Ministry for Economic Affairs and Climate Action. We develop and provide innovative single house to grid-connected district heating and cooling solutions. As geothermal source, very shallow geothermal collector systems and their special forms (e.g. trench collectors, heat baskets) with maximum installation depth of 5 m are used. The 30 partners cover the entire value chain from research via planning and industry to energy suppliers and municipal utilities. The network is coordinated by the Geozentrum Nordbayern of the Friedrich-Alexander University of Erlangen-Nuremberg.
