Page 1 of 2 JAKARTA. Already a lot about the potential of geothermal Reviewed owned Indonesian nation. The potential is very abundant not in line with its utilization is still minimal due to some constraints. But this should not deter the Government intention to keep trying as much as possible exploit the existing potential by seeking a settlement of existing constraints.
With geothermal energy that is possessed, if the optimal utilization of the Indonesian nation not only can meet the electricity needs but has a chance to become exporters of geothermal-based electricity. Indonesia's geothermal potential is currently reaching about 28 GW and its utilization only around 4% (1189 MW). To get to know about the source of energy produced from geothermal follows below a brief explanation of these related articles extracted from PT Pertamina (Persero) written SBTI-General Affairs & Human Resources Directorate, Gilbert Hutauruk. Geothermal lies beneath the skin of the earth, each 100 meters of us descends into the bowels of the earth, rocks, liquid temperature was up around 30 C. So the further into the bowels of the earth temperature rocks or mud will be higher. When the temperature at the earth's surface is 270 C then to a depth of 100 meters the temperature can reach about 300 C. To a depth of 1 kilometer temperature rocks and mud can reach 57-600 C and at a depth of 2 kilometers of rock and mud temperature can reach 1200 C or more. At the Earth's crust there are times when the flow of water very close to the hot rocks where temperatures can reach 1480C. Water will not be a vapor (steam) because there is no contact with air. When the hot water had been able to get out onto the surface of the earth because there are gaps or cracks occur in the skin of the earth, cause the hot water is usually called the hot springs. Furthermore, if the natural hot water mixed with air due to a fracture or crack the addition of hot water will come out too hot vapor (steam). Hot water and steam is then used as a source of electrical power. In order to heat the earth (geothermal) could be converted into electrical energy generator of course necessary (power plants). Geothermal reservoir is usually classified into two groups, namely the temperature was low (low temperature) with temperatures <1500 C and high temperature (high temperature) with a temperature above 1500 C. It's best to use as a source of power generation is entering the category of high temperatures. However, with technology development, geothermal resources with low temperatures of the category can also be used provided the temperature exceeds 500 C. Generator (power plants) to pembang-kit is a geothermal power plant can operate at relatively low temperatures ranging from 122 s / d 4820 F (50 s / d 2500 C). Compare this with the nuclear power plant that will operate at a temperature of about 10 220 F or 5500 C. This is one of the benefits of geothermal power plants. Another advantage is clean and safe, even geothermal is the cleanest compared with nuclear, petroleum and coal. [esdm] www.tenderoffer.biz
