Geothermal energy, a story of innovation and sustainability
Historical, natural, renewable, innovative, clean and practically inexhaustible: we’re talking about geothermal energy. Heat from the Earth’s core in the form of steam is a resource that has been part of the story of human civilization since ancient times and has been used in all of its possible forms: for heating, cooking, thermal baths and, of course, for producing electricity.
While geothermal energy still plays a relatively marginal role as an energy source in our country (around 2%), Italy is one of the main producers of geothermal energy not only in Europe but worldwide, thanks to the wealth of geothermal resources concentrated in various parts of the Italian peninsula and ready to be exploited as key elements of the energy transition.
Geothermal energy for the energy transition
With a view to taking full advantage of the potential of underground heat, Enel Green Power, together with the company Vulcan Energy, is working just to the south of this area on the ambitious Zero Carbon Lithium project, through which we are endeavoring to extract lithium from geothermal brines. Demand for this element, which is indispensible for the production of electric car batteries, is set to increase in the coming years, which is why we need to find solutions that have less environmental impact and are more sustainable in terms of resources. The project’s starting point is in Cesano on the outskirts of Rome, where almost half a century ago some of the highest concentrations of lithium ever recorded worldwide were discovered at a depth of around 1,300 meters.
