“…In the view of decreasing energy resources, the discussion about climate change and a fast-growing world population, there is an increasing interest in the use of geothermal heat potential of rocks at depth. The use of geothermal energy has a long tradition in countries with active volcanism (Bertani 2005). There are also remarkable geothermal resources in Germany, even though the temperature is rather moderate in the subsurface (Jung 2007).…”

Evaluation of the representative elementary volume (REV) of a fractured geothermal sandstone reservoir

The objective of this study is to evaluate a representative elementary volume (REV) in a fractured geothermal sandstone reservoir in Germany using the discrete fracture network (DFN) model approach. Due to the lack of in situ data from the deep geothermal reservoir, field measurements of outcrop reservoir analogues were conducted to get a quantitative description of the DFN. Field measurements reveal that the geometry of the DFN is largely influenced by the lithological layering (e.g. relationship between joint spacing and bed thickness). Thus, DFN models have to be completed individually for each layer since each bed is distinct compared to its neighbouring beds. Various DFNs were generated using statistical-derived fracture input data. The two-dimensional universal distinct element code UDEC was used for fracture flow simulations. In order to determine the minimum REV, the equivalent average conductivity tensors were obtained with increasing block size. Plots of conductivity tensor coefficients versus block size exhibit only minor variation of the hydraulic properties with increasing block size. Hence, an REV size of 10 m 9 10 m could be determined for all studied stochastically derived discrete fracture networks.

“…From 1950 to 2015 the total worldwide install capacity and power generation from geothermal power plants has steadily increased. It is predicted to almost double from a capacity of 12,635 MWe and an energy output of 73,549 GWh in 2015 to a capacity of 21,443 MWe with an uncalculated energy output production [8]. The figures below illustrate the relationship between installed capacities versus produced energy to gauge the growth of geothermal power production.…”

This meta-study draws upon previous research on both Enhanced Geothermal Systems (EGS) and traditional geothermal systems (GS), using these findings to compare and investigate the thermal efficiency of each system. Efficiency calculations include reservoir enthalpy, maximum drilling well temperature, power output (per unit mass of liquid) and mass flow rate of these systems to determine whether EGS’s are viable as an alternative, more readily available renewable energy source. This meta-study suggests that EGS are more viable than naturally occurring GS in the context of future geothermal energy production as they perform with a similar average efficiency of 10-15% and, in addition, can be used in a wider range of geothermal environments.

“…The costs are extremely high to build a geothermal power station, which includes extensive earthwork and testing [5]. For these reasons, applications of geothermal electricity generation remain very limited, accounting for less than half a percent of energy use in both the United States and China [6].…”

ABSTRACT:With growing concerns about the future and security of the world's energy supply, various renewable energy technologies have been used thorough the millennium. Renewable energyproduction for the generation of electricity is very appropriate and rather practical for development particularly in rural areas.Finding alternative sources of electrical energy that are both economical and environmentally sustainable is pivotal for improving the quality of life in communities. Photovoltaic-the direct conversion of solar energy into electricity-has a history of about 50 years. This field of study and the resulting industry have been rapidly growing and improving and are expected to become a significant part of the world's energy future. Additionally, the use of solar energy over the recent years has increased dramatically especially in rural areas. This paper will focus on providinga guideline to help utility companies in area who may consider investing in an appropriate renewable electricity generation project and for the responsible agencies to support such investment.Evaluationof renewable energy in general and photovoltaic in particular to produce electricity in the Eastern Shore of Maryland is undertaken in this study.
