ThermoMap - An Open-Source Web Mapping Application for Illustrating the very Shallow Geothermal Potential in Europe and selected Case Study Areas
- Due to climate change and new political reasons to use more sustainable energy forms (turning away from nuclear, coal and other non-renewable resources), alternative energy sources are needed. Therefore, the geothermal energy sector can become one of the important energy resources in the future. Geothermal energy (heat) is CO2-neutral, quasi-inexhaustible and available decentrally at any time and almost everywhere. The exploitation of deep geo-thermal resources for producing electricity is an important component for creating innovative and renewable energy systems, but the use of shallow (focus: up to 400 metres depth) and even very shallow (focus: up to 10 metres depth) geothermal potentials is also significant, e.g. for sustainable heating and cooling of residential and industrial buildings, etc. Furthermore in Europe, the installation and operation of very shallow heat collector systems is not as restricted by national and regional legislation as for deeper systems. Compared with the well-researched and already implemented solar, wind and hydropower domains, less research has been done into the of very shallow geothermal energy potential at the European level.

Overview and perspectives on shallow geothermal energy in Belgium
- The current energy transition towards Renewable Energy Sources (RES) in Europe is mainly driven in Belgium by wind turbines and photovoltaic panels. However Ground Source Heat Pumps (GSHP) has not yet reached the full attention of Belgian authorities and customers while the potentialities in the country for heating/cooling market by GSHP for housing and micro- to medium-sized enterprises are important. The specificities of the Belgian market, especially the attractiveness to install GSHP for individual housing is related to various socio-economic factors. The main barrier to the relatively slow growth rate with respect to other forms of RES can be partially explained by the estimated extra-cost. This is due to frequent overdimensioning of shallow geothermal systems during the design phase. These overestimations could be addressed by the improvement of data accuracy of thermal parameters of geological formations in Belgium. Various geothermal projects acting for the development of shallow geothermal energy, as well as its perspectives tackles the different technical and administrative barriers.

A tight association in genetically unlinked traits in sympatric and allopatric populations of a saltmarsh beetle
- Local adaptation likely involves selection on multiple, genetically unlinked traits to increase fitness in divergent habitats. Conversely, recombination is expected to counteract local adaptation under gene flow by breaking down adaptive gene combinations. Western European populations of the salt marsh beetle Pogonus chalceus are characterized by large interpopulation variation at various geographical ranges in two traits related to dispersal ability, i.e. wing size and different allozymes of the mitochondrial NADP?-dependent isocitrate dehydrogenase (mtIdh) gene. In this study, we tested whether variation in wing length was as strongly genetically determined in locally adapted populations in a sympatric mosaic compared to allopatric populations, and if variation in mtIDH and wing size was genetically unlinked. We demonstrate that the genetic determination of wing size is very high (h2 = 0.90) in sympatry and of comparable magnitude as geographically separated populations. Second, we show that, although frequencies of mtIDH allozymes are tightly associated with mean population wing size across Western European populations, the correlation is strongly reduced within some of the populations. These findings demonstrate that the divergence involves at least two traits under independent genetic control and that the genetically distinct ecotypes are retained at geographical distances with ample opportunity for gene flow.
