A research team at the Island came to drill down to earth magmalag and had to stop their geothermal experiments. But the incident may prove to pave the way for a new and more efficient use of renewable energy in the form. By Michael Reiter April 13, 2011 at. 06:01
In 2009, international researchers drilled a very deep hole in the tenth kilometer crater Krafla Cadera, which is part of an active sobeys pay stubs Icelandic volcano system. The energy company Landsvirkjun wanted to find out whether very hot water under very high pressure - so-called "supercritical" water - can be used as an energy source.
"We were several months sobeys pay stubs behind schedule and hugely frustrated with all drilling problems. But now suddenly it becomes a huge discovery, "says Robert Zierenberg, professor of geology at the University of California.
A detailed analysis of the well IDDP-1 showed that the magma produces dry steam with temperatures above 400 degrees Celsius - three times as hot as normal geothermal wells. The researchers write in an article that has just been published in the trade journal Geology.
The research team believes that the steam to generate sobeys pay stubs power with an output of up to 25 MW - enough to power between 25,000 and 30,000 households. Conventional geothermal sources when usually only up to 5:00 to 8:00 MW.
By drilling close to magmakilder in areas of high volcanic activity, the energy companies did achieve a significantly higher yield. Not only does it save companies huge sums because they can make do with fewer wells. Geothermal energy can also become a much more important source of renewable energy.
In the energy company Landsvirkjun is however certain that it is possible to build new turbines for the purpose - including based on experience in the production of electricity from nuclear and fossil sources. It will take more samples to analyze how best to use steam, and whether to build a power plant on site.

The idea's good and attractive in the energy times, but there probably should not put too much faith in supply stability when an earthquake or self. volcanic sobeys pay stubs eruptions could periodically plant to the ground in a relatively short time.
If steam at 400 degrees is three times as hot as a normal steam, as is common steam minus 48 degrees (Celsius).
Low pressures and temperatures used mostly for heating High data used for steam turbines, the highest achieved with kulfurede boilers. The vast majority of nuclear power plants are operated with steam at about 260 C and 70 bar, no advantage for steam process, sobeys pay stubs but entirely possible.
If these trials have demonstrated the superheated steam with gravel and other contaminants from underground, one can certainly construct turbines also for this blend. If you can get pure steam via an underground heat exchanger (kettle), it is a great relief for a steam turbine with clean and superheated sobeys pay stubs steam. It must not be forgotten is the long pressurized feed water stage data momentum.
I've just been on a trip to Iceland and see the geothermal plant. They run very well but energy is a problem in Iceland. They have too much of it and export of energy is a problem. There are approximately 1800 km to the mainland and by the children themselves cost a cable 2 x Iceland's GDP. My suggestion is to make hydrogen out of the extra energy and ship it to Europe by ship and turn it into electricity. Yes there will be no loss in efficiency but rather energy loss than no energy. It could also kick off hydrogen car technology.
