Geothermal know-how, from Europe to the rest of the world
Europe is undoubtedly the number one in geothermal energy technology, which is being exported all over the world. A new trend, tested by Italian utility Enel Green Power, is to combine geothermal energy with other renewable energy technologies, making geothermal plants more efficient and sustainable.
Recently, Enel combined geothermal energy with hydropower in Cove Fort, United States to provide more electricity for the plant's operation. The innovation involves the installation of one generator in a reinjection well, which produces electricity from the falling flows of water previously used by the geothermal plant. The result is an unprecedented innovation that reduces operating and maintenance costs, while offering the opportunity to generate additional revenues.
The ground-breaking technology, the first in the world in such large scale, originates in Italy, where the phase of research and design took place. The company’s power plants around the world are in fact controlled by young Italian engineers working from the geothermal plants in the Italian provinces of Pisa, Siena and Grosseto.
