Faisabilité d'exporter de l'électricité "géothermique"
islandaise vers la Grande-Bretagne et la Norvège...
OSLO - Statoil ASA , Norway's largest oil and gas group, said this
week that it was studying the possibility of exporting Icelandic geothermal
electricity to Britain and Norway.
It said in a statement that it had signed
a letter of intent with Norwegian grid operator Statnett and Icelandic
power group Landsvirkjun to do a feasibility study by early 2003 of a 600
MW power station.
Under the plan, geothermal energy from a depth of 1,000-2,000 metres
would drive turbines tied to electricity generators. It said that a power
station would generate about five terawatt hours a year, or 4-5 percent
of Norway's annual hydropower output.
If the plant were built, a submarine power cable
about 1,200 kms (745.6 miles) long would have to be laid, either to Britain
or Norway or to both. Transmission losses over the cable would be about
Statoil said preliminary assessments indicated that
the project could compete with other types of renewable power but that
geothermal power from Iceland was not competitive at current prices.
Even so, many nations are demanding that a certain
percentage of power be generated from non-polluting sources, such as geothermal
power, to help cut emissions of greenhouse gases blamed for global warming.
