Experts give 50 percent of the success of this project. And if it will work, I could produce the same amount of electricity as a small nuclear power plant. Operating principle geothermal power, Iceland makes geothermal energy into electricity in two ways: from the well Steaming temperature 600 F, which is fed directly to the turbine, and a more efficient method, which gives supercritical water from deep wells, making steam that drives a turbine. The natural supply of supercritical water and turning it into electricity, would be like to transition from diesel to jet fuel. To assess the benefits available to natural supercritical water, we say that the majority of power plants and nuclear power plants also produce supercritical water before generate electricity. Power stations produce thermal energy produced by burning coal or radioactive decay of isotopes to the water in a sealed tank turned into a supercritical state.
The process allows water maintain high-energy intermolecular bonds in the liquid state until it flows through the pipes, with almost zero resistance, as a gas. Two and a half miles of underground water heated by magma to 1100 . At this temperature, it usually exist as pairs, but a lot of pressure keeps it liquid. And if the water is released to the surface in the supercritical state will retain almost all its energy. But engineers will have to redesign the existing heat exchangers, so that they can operate with high temperatures and resisted corrosion. Then the power plant running on natural supercritical water could produce up to 500 b megawatts of electricity, along with a small nuclear reactor or power plant at half capacity. But unlike them, geothermal power plants using renewable and virtually no comprehensive source of energy, with zero emissions. Prospects for development of geothermal energy in Iceland now uses its geothermal potential is only 20 percent of the total possible.
If they had exploited all the resources of the island only in the usual way, we could produce 20 gigawatts of electricity per hour per year – as three nuclear reactors. Iceland uses geothermal energy to start from the beginning of the XX century. On the island there are five district heating geothermal power plants with total power capacity of 420 MW, which produce 26.5% of all electricity in the country, and 90 percent of their heating and hot water is heated by geothermal energy. Possible But the problems of such a large project, there are serious problems and risks. At worst, it can release and leakage of water under high pressure, then unrestrained fluid flow will sweep the whole rig, which happened to One of Iceland's projects in 1999, then, because of the failure of valve used to isolate the source in case of ejection, there was an explosion, which left behind a crater 30 meters wide. It is also possible that deep-water containing hydrochloric acid and the liquid for several hours without any problems melt steel. Also, the drill may stumble directly to the magma, or skip supercritical water, then you have to leave this area and drill elsewhere. Iceland established its own project using geothermal energy, which may be an example for countries with similar terrain. Japan and Italy are open about their potential supercritical water, but Iceland is the first country has made a big step in the use of geothermal energy. News of science and technology
