Generating Electricity from Magma
An accidental encounter of scientists in Iceland with molten lava has opened possibilities of harnessing under surface heat to produce power. A geothermal borehole project in Iceland a few years ago accidentally struck magma and its super-heated steam. This super-heated steam can be harnessed to produce electricity.
The Icelandic Deep Drilling Project (IDDP) has been drilling shafts up to 5 km deep in an attempt to harness the heat in the volcanic bedrock far below the surface of Iceland. The plant is the first on the planet to use steam produced by molten rock or magma.
Iceland: A hub of Geothermal Energy
Geothermal energy is harnessed by pumping cold water into hot dry rocks around 4 km below the surface. Iceland relies on geothermal power for two-third of its energy.
Currently 90% of homes in Iceland are heated by geothermal power which is both renewable and sustainable. Unlike solar power and wind, geothermal power has the potential to be harnessed 24 hours a day, 7 days a week. This type of energy has been expensive and unreliable in other parts of the world, however.
