Projektbeschreibung
Heißes Gestein zur Nutzung von Wärme in geothermischen Lagerstätten sanft aufbrechen
Der Erdkern ist ein ungemein heißer Schmelzofen. Ein Teil seiner Wärme erreicht die Erdkruste und ist für den Menschen zugänglich. Fortgeschrittene geothermische Systeme sind so konzipiert, dass sie diese Wärme als nachhaltige Energieform für verschiedene Zwecke, einschließlich der Stromerzeugung, erschließen. Bei diesen Systemen wird ein Fluid in den Boden injiziert, wodurch sich bereits vorhandene Risse wieder öffnen und das Fluid zirkulieren und Wärme aufnehmen kann. Aufbauend auf früheren Projekten und wissenschaftlichen Fortschritten in anderen Bereichen (vor allem im Öl- und Gassektor) wird das EU-finanzierte Projekt DESTRESS kürzlich entwickelte „Stimulationsmethoden“ an geothermische Anwendungen anpassen. Das Team wird sich auf die „sanfte Stimulation“ konzentrieren, um die Bedenken der Öffentlichkeit im Zusammenhang mit hydraulischer Rissbildung auszuräumen.
Ziel
DESTRESS is aimed at creating EGS (Enhanced geothermal systems) reservoirs with sufficient permeability, fracture orientation and spacing for economic use of underground heat. The concepts are based on experience in previous projects, on scientific progress and developments in other fields, mainly the oil & gas sector. Recently developed stimulation methods will be adapted to geothermal needs, applied to new geothermal sites and prepared for the market uptake. Understanding of risks in each area (whether technological, in business processes, for particular business cases, or otherwise), risk ownership, and possible risk mitigation will be the scope of specific work packages.
The DESTRESS concept takes into account the common and specific issues of different sites, representative for large parts of Europe, and will provide a generally applicable workflow for productivity enhancement measures. The main focus will be on stimulation treatments with minimized environmental hazard (“soft stimulation”), to enhance the reservoir in several geological settings covering granites, sandstones, and other rock types. The business cases will be shown with cost and benefit estimations based on the proven changes of the system performance, and the environmental footprint of treatments and operation of the site will be controlled. In particular, the public debate related to “fracking” will be addressed by applying specific concepts for the mitigation of damaging seismic effects while constructing a productive reservoir and operating a long-term sustainable system.
Industrial participation is particularly pronounced in DESTRESS, including large energy suppliers as well as SMEs in the process of developing their sites. The composition of the consortium involving major knowledge institutes as well as key industry will guarantee the increase in technology performance of EGS as well as an accelerated time to market.
