“…Después de todo, para la mayoría de los pozos profundos no hay datos preexistentes en los que basar un modelo confiable (Vienken et al 2014). En este espíritu, un popular libro de ciencias sobre energías renovables argumenta sin rodeos que en la localización de sitios adecuados de fuentes de energía geotermal no existe manera de medir con precisión el verdadero potencial.…”

Revista Internacional de Sociología 75 (4) ResumenLos combustibles fósiles no-renovables hicieron posible lo que se ha llamado el mundo moderno. Dado que los recursos no renovables son cada vez más difíciles y costosos de extraer, la transición a fuentes de energías renovables es una tarea crucial. En orden a enmarcar posibles caminos hacia la innovación responsable y transición dentro de las sociedades democráticas, este artículo se construye en torno al concepto de experimentos "terrenales" o fuera-del-laboratorio para destacar algunas de las condiciones y procesos que pueden promover procesos colectivos de aprendizaje. Esto es hecho por medio de ejemplos empíricos con respecto al establecimiento de sistemas de energía geotérmicas. El artículo trabajará sobre la noción sociológica de experimentos terrenales, entendiéndolos como parte sustantiva de la sociedad, con el fin de destacar críticamente qué podría significar una "ciencia" así concebida para una ciudadanía democráticamente constituida. El artículo mostrará cómo estos procesos experimentales lidian con cuestiones referentes a la aceptabilidad y la gobernanza democrática, y de qué manera aparecen y se gestionan los límites de la experimentalidad de cara a sus desafíos políticos. Mostramos que los "experimentos a la intemperie" tendrán que enfrentarse con incertidumbres crecientes y la inevitable ignorancia que complica las condiciones para la transición hacia energías renovables, pero que también pueden abrir nuevos caminos para involucrar a la ciudadanía en procesos de exploración tecnocientífica. PalabRas ClaveEnergías renovables; Experimentación; Participación; Sustentabilidad. abstRaCtNon-renewable fossil fuels made possible what has been called the modern world. Given that non-renewable resources are increasingly becoming more and more difficult and costly to extract, the transition to renewable energy sources is a crucial task. In order to frame possible avenues towards responsible innovation and transition in democratic societies, this paper will built on the concept of "earthly experiments" to highlight some of the conditions and processes that may foster responsible innovation and learning processes. This is done by building on empirical examples from the establishment of geothermal energy systems. The paper will then unfold the sociological notion of earthly experiments in order to critically highlight on what this could mean to democratically constitute citizens as part of "science" thus conceived. The paper will show how such experimental processes deal with questions of acceptability and democratic governance, and how the political limits of experimentality are rendered visible and manageable. We show to what extent "experiments in the wild" are able to cope with increasing uncertainty and the unavoidable ignorance that complicate conditions for the transit...

“…This in turn can be used for a site-specifically optimized and cost-efficient system design and for a reliable assessment of changes in soil and ground water temperatures induced by the geothermal use. Therefore, novel site characterization approaches and techniques are needed (Vienken et al 2015). Accordingly, Seibertz et al [at http://angusplus.de/en/publications/journal-articles (doi:10.…”

New techniques and methods for energy storage are required for the transition to a renewable power supply, termed ''Energiewende'' in Germany. Energy storage in the geological subsurface provides large potential capacities to bridge temporal gaps between periods of production of solar or wind power and consumer demand and may also help to relieve the power grids. Storage options include storage of synthetic methane, hydrogen or compressed air in salt caverns or porous formations as well as heat storage in porous formations. In the ANGUS? project, heat and gas storage in porous media and salt caverns and aspects of their use on subsurface spatial planning concepts are investigated. The optimal dimensioning of storage sites, the achievable charging and discharging rates and the effective storage capacity as well as the induced thermal, hydraulic, mechanical, geochemical and microbial effects are studied. The geological structures, the surface energy infrastructure and the governing processes are parameterized, using either literature data or own experimental studies. Numerical modeling tools are developed for the simulation of realistically defined synthetic storage scenarios. The feasible dimensioning of storage applications is assessed in sitespecific numerical scenario analyses, and the related spatial extents and time scales of induced effects connected with the respective storage application are quantified. Additionally, geophysical monitoring methods, which allow for a better spatial resolution of the storage operation, induced effects or leakages, are evaluated based on these scenario simulations. Methods for the assessment of such subsurface geological storage sites are thus developed, which account for the spatial extension of the subsurface operation itself as well as its induced effects and the spatial requirements of adequate monitoring methods.

“…Three dimensional model simulations and visualizations are a basis for the comprehensive understanding of complex processes within the subsurface. Moreover, this visualization approach is an important tool to identify missing data and to prove consistency of data from different sources (Vienken et al 2014). In the case of the Taucha field site, it enhances understanding of temperature anomalies (e.g., heat plume formation) along borehole heat exchanger after different operating times.…”

Scientific visualization is an integral part of the modeling workflow, enabling researchers to understand complex or large data sets and simulation results. A highresolution stereoscopic virtual reality (VR) environment further enhances the possibilities of visualization. Such an environment also allows collaboration in work groups including people of different backgrounds and to present results of research projects to stakeholders or the public. The requirements for the computing equipment driving the VR environment demand specialized software applications which can be run in a parallel fashion on a set of interconnected machines. Another challenge is to devise a useful data workflow from source data sets onto the display system. Therefore, we develop software applications like the OpenGeoSys Data Explorer, custom data conversion tools for established visualization packages such as ParaView and Visualization Toolkit as well as presentation and interaction techniques for 3D applications like Unity. We demonstrate our workflow by presenting visualization results for case studies from a broad range of applications. An outlook on how visualization techniques can be deeply integrated into the simulation process is given and future technical improvements such as a simplified hardware setup are outlined.
