ICELAND AT GEOTHERMAL’S CUTTING EDGE
Iceland Is Pushing Geothermal Boundaries With Magma-Generated Power
Meagan Clark, February 17, 2014 (International Business Times)
Molten rock that bursts out of volcanoes may increasingly provide energy to power homes and businesses in Iceland and beyond… The Icelandic Deep Drilling Project (IDDP) had been drilling shafts into volcanic bedrock up to 5 km (3.1 miles) deep and capturing the intense heat when, in 2009, a team struck an underground pool of magma. The borehole, IDDP-1, became the first of many wells…The new method of using magma to generate high-pressure steam over 450 degrees Celsius (842 degrees Fahrenheit) set a world record for highest geothermal heat and was the first time heat from molten magma (vs. solid rock) was used to produce electricity…Normal geothermal energy is harnessed by pumping water into hot, dry rocks…But normal geothermal heat doesn’t reach the temperatures magma can…The IDDP's experiment stretched the known capability of geothermal, showing that magma-heated steam can be an energy source…” click here for more
