10 Η ΓΕΩΘΕΡΜΙΑ ΩΣ ΠΗΓΗ ΗΛΕΚΤΡΙΣΜΟΥ Εφαρμογές Γεωθερμίας_ Παραγωγή Ηλεκτρισμού electricity Basic process for electricity generation: 1. Drilling rigs probe reservoir in search of superheated fluid (steam/water). 2. Production wells conduct the hot fluid to the surface. 3. Generating units use the fluid energy to produce electricity: a) If the fluid is water, it is flashed to steam in special vessels by release of pressure. b) The steam is fed to spin a turbine engine, which turns a generator and electricity is produced. 4. The remaining hot water can be reused for heating (home heating, greenhouse, vegetable drying or a wide variety of other small scale industries), evaporates, or is cooled in a cooling tower.

11 Η ΓΕΩΘΕΡΜΙΑ ΩΣ ΠΗΓΗ ΗΛΕΚΤΡΙΣΜΟΥ Εφαρμογές Γεωθερμίας_ Παραγωγή Ηλεκτρισμού electricity Advantages: Renewable Energy Source Clean Source with minimum emissions (CO 2, SO 2 ) and equipped with emission-control systems to reduce the exhaust of greenhouse gases carried by drawn fluids. Geothermal fields produce only about 1/6 of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces. Binary plants release essentially no emissions. Direct use, no need to transfer supply Reliable and constant, does not have the volatility of other renewable energy sources Minimal land and freshwater requirements Cost-effective not dependant on changing fuel prices, costs for maintenance is quite low. Geothermal plants are modular. As a result they can be installed in increments and be transported conveniently to any site. Both baseline and peaking power can be generated.

12 Η ΓΕΩΘΕΡΜΙΑ ΩΣ ΠΗΓΗ ΗΛΕΚΤΡΙΣΜΟΥ Εφαρμογές Γεωθερμίας_ Παραγωγή Ηλεκτρισμού electricity Potential Issues: High upfront costs. Most of them refer to exploitation and drilling. Can have negative impacts on water consumption and groundwater quality. However most geothermal facilities have closed-loop water systems, in which extracted water is pumped directly back into the geothermal reservoir after it has been used for heat or electricity production. Impact on land stability. Land subsidence or earthquakes are possible. Release of toxic and global warming air emissions from the wells. The disposal of some geothermal fluids, which may contain low levels of toxic substances. Over exploitation of geothermal sites can affect the capacity of the geothermal field Connection of plant with national grid if placed in remote locations

13 Η ΓΕΩΘΕΡΜΙΑ ΩΣ ΠΗΓΗ ΗΛΕΚΤΡΙΣΜΟΥ Εφαρμογές Γεωθερμίας_ Παραγωγή Ηλεκτρισμού electricity Geothermal power generation is a well established and relatively mature form of commercial renewable energy with 11,400 MW of geothermal power online in 24 countries (2012). It has a high load factor, higher than wind or solar, which means that each MW of installed power capacity produces significantly more electricity during a year. It is continuous rather than intermittent, can be better integrated to the grid and final energy consumption mix. In European region, Greece, Italy and Iceland have geothermal fields of high temperatures capable of electricity production.
