Italy leads the list of countries with the highest dependence on electricity imports. At the same time, the Italian Enel Green Power is among the pioneers and leaders in the study and implementation of geothermal energy technologies, the only company in the world that is able to independently carry out the entire development cycle of a geothermal energy facility from the exploration phase to the direct construction of the power plant and its further operation. Back in 1904, the Italian prince Pietro Ginori Conti conducted experiments in Tuscany to transform steam energy into electricity. In 1913, the world’s first geothermal power plant was opened in Larderello, which is more than 100 years old. In fact, 10% of the world’s geothermal energy is produced by this single oldest complex of 34 power plants with a combined capacity of 769 MW. This is a significant contribution to the total renewable energy capacity in Italy, where geothermal capacity has grown more than 6 times in the last decade. Technologies for using geothermal energy are standard practice with a high degree of reliability and a further prospect of increasing capacity. The development of electrolysis production of hydrogen based on geothermal renewable energy looks promising to cover its own energy needs and further export pipeline hydrogen to neighboring countries, which will certainly give an impetus to the development of the Italian economy within the framework of decarbonization in accordance with international agreements to reduce greenhouse gas emissions. Such projects only confirm a unified unified approach to building projects of different localization in places of reserves of geothermal energy with the benefit not only for their own needs, but also for systemic interstate development.
