Geothermal energy
— Geothermal technologies use renewable energy resources to generate electricity and direct use of heat while producing very low levels of greenhousegas (GHG) emissions. Geothermal energy is the thermal energy stored in the underground, including any contained fluid, which is available for extraction and conversion into energy products. Electricity generation, which nowadays produces 73.7TWh (1...
متن کاملEstimating Limits for the Geothermal Energy Potential of Abandoned Underground Coal Mines: A Simple Methodology
Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by abandoned and flooded underground mines in Europe. From a few practical considerations, a procedure has been...
متن کاملHeat extraction of novel underground well pattern systems for geothermal energy exploitation
The current Enhanced Geothermal Systems (EGS) with a fractured reservoir undergoes several practical issues, such as scaling in the wellbore, the mass flow loss into the reservoir, and the challenge in designing the placement of production wells. In this paper, novel underground well pattern systems were proposed for geothermal energy exploitation. A numerical model of two kinds well pattern sy...
متن کاملGeothermal Energy in Iceland
Due to Iceland’s location on the Mid-Atlantic ridge, the island is provided with a great amount of geothermal energy. Hence, Iceland is well on the way to becoming completely independent of fossil fuels. Whereas high-temperature areas are mainly used for electricity generation, the more frequent low-temperature areas are utilized for direct application like space heating, bathing and greenhouse...
متن کاملGeothermal Energy in Finland
The use of geothermal energy in Finland is restricted to the utilization of ground heat with heat pumps. This is due to the geological conditions as Finland is a part of the Fennoscandian (or Baltic) Shield. The bedrock is Precambrian covered with a thin (<5 m) cover of Quaternary sediments. Topography is subdued and does not easily produce advective re-distribution of geothermal heat by ground...
