Geothermal energy applications

Unique Design Features for Geothermal Energy Recovery Applications... 

Direct geothermal energy is used for space heating of homes, greenhouses, livestock barns, and fish-farm ponds. As well, it is employed as a heat source in some industrial processes, such as paper production in New Zealand and diying diatomite in Iceland. Since the industrial applications usually require high-...

Stress induced permeability change is of crucial importance in various kinds of applications such as nuclear waste disposal in deep geological formations, geothermal energy utilization and underground excavations. In particular, coupling between the stress and permeability is a key element in understanding the nature of flow in the fractured rock (Rutqvist and Stephansson, 2003). This is because fractures, which are the main pathways of fluid flow in fractured hard rocks, are heavily dependent on the stress conditions for their deformations. 

Extraction depths may exceed 3000 m and any equipment failures can result in extremely expensive shutdowns. Accordingly the industry is willing to use the very highest performance materials such as PEK and PEKEKK as well as PEEK. It is worth noting that PAEK find many of the same applications in geothermal energy production which also faces high temperatures and pressures in a superheated water environment.
