Possible Impacts: This technology could have widespread application. For more information visit GTP''s Web site at Find details on projects
Of these, shallow geothermal energy refers to the low-temperature heat that is contained in the soil, gravel, and groundwater within a depth of 200 m from the shallow surface of the earth (Hähnlein et al., 2013).
The distribution of geothermal resources is closely related to the geological tectonic activity. The high-temperature geothermal resources are located in the marginal zone of the plate with an abnormal tectonic activity (eg, Himalayan and Taiwan geothermal belts). 27 The low- and medium-temperature geothermal resources are
Deep Low-Temperature Geothermal Energy. The principle behind deep low-temperature energy is the same as for other low-temperature varieties, except that the wells descend further below the surface, to depths of 200 to 2,500 meters, and that the water temperatures are higher, generally between 30°C and 90°C. The water is
Medium and low-temperature convective geothermal resources are a crucial component of China''s geothermal wealth, primarily concentrated in the eastern coastal regions. To maximize the utilization of these resources, geophysical surveys are essential, with acoustic-emission geomagnetic bathymetry being a prominent and
In this paper, a low-temperature geothermal organic Rankine Cycle (ORC) power generation system model is established. R245fa is used as the circulating working fluid. The calculation program is compiled using the engineering calculation software EES, and the thermodynamic parameters and thermodynamic properties of the main state
This paper presents the results of a laboratory study on grouts with a novel binder characterized by high thermal conductivity, designed for low-temperature geothermal applications. The highly thermally conductive binder was prepared by milling expanded graphite together with Portland clinker to obtain a homogenous mixture
Carry out geothermal heating and cooling and power generation by conducting comprehensive demonstration projects, including middle and low
Hydrocarbon fields around the world may possess suitable features for low-temperature geothermal energy extraction (below 190 °C). Few demonstration plants
The low-temperature geothermal potential of the flooded Gaspé Mines, near Murdochville, Québec, Canada, has been estimated from a long-term pumping test and numerical groundwater flow modelling
We derive our deep resource potential estimates (3.5–6.5 km) from those developed by C. Augustine (''An Estimate of Shallow, Low-Temperature Geothermal Resources of the United States
Low-temperature and co-produced resources represent a small but growing sector of hydrothermal development in geothermal resources below 150°C (300°F). Considered non-conventional hydrothermal resources, these technologies are bringing valuable returns on investment in the near-term, using unique power production methods.
Geothermal energy and in particular low temperature re- sources, have a rising worldwide importance. Ground-Source Heat Pumps (GSHP) have been used increasingly because they are among the cleanest and most energy efficient heating and cooling systems for buildings. Simulation models can be applied for a more effective use of the subsoil for
It shows 10% higher net power output, 3% lower V1, 1.0 time higher Expr, and 22% reduction of total heat transfer areas compared with baselines given geothermal source temperature of 90 C. With the geothermal source temperature above 100°C, R32 and R143a also show better performances.
Typically, low-temperature geothermal resources are less than 90 C and may be applied for small-scale power generation, but are more readily useful for direct-use applications. A potentially useful application of the geothermal energy from low-temperature
Geothermal energy is thermal energy extracted from the Earth''s crust combines energy from the formation of the planet and from radioactive decay.Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times
6 · Geothermal resources are increasingly gaining attention as a competitive, clean energy source to address the energy crisis and mitigate climate change. The
Low-temperature geothermal uses include geothermal heat pumps (GHPs) for individual homes and businesses, district heating and cooling, and direct-use applications, where
From the second space point of view, the low-enthalpy geothermal heat, i.e. ~<2000 m depth within the Earth''s Critical Zone (corresponding to the earth temperature < 85 C), can be recoverd using
Geothermal energy in Sweden is dominated by low temperature, shallow geothermal energy systems and direct use. The vast majority of installed geothermal energy systems are ground source heat pumps
The main problem of low temperature geothermal power generations is their poor economic efficiency because the drilling cost accounts for more than 50%. At present, numerous oilfields in the world enter the high water-cut stage, and the average water-cut is close to 95%, or even higher than 98%.
