Abstract Many articles have been published on the pioneering activity carried out in Larderello for the exploitation of the geothermal resources present there. Little is known, however, of the equally pioneering activities carried out in Italy around 500 km south of Larderello for the exploitation of the warm waters found on the Ischia island in front of the Gulf of Naples. With this article we want to analyze the technological evolution that since the 1930s has made it possible to produce electricity from hot water. There are many factors that have made this pioneering development possible. The first one is linked to the geological conditions present on the island, the second one concerns the evolution of the drilling activity which has made available more and more hot water and then steam. The third is linked to the presence, at the engineering faculty of the "Federico II" University of Naples, of creative minds who have designed and made possible the realization of prototypes of binary fluid systems. Starting from a small size of 10 CV (1 CV = 0,98631 HP) working with pure fluids, reaching a size of 300 kW working with immiscible fluids mixtures. In this way they have anticipated the future development of this technology. The article analyzes all these factors to describe the birth, development and decline of this unique experience from which valid lessons can be drawn even in our day.

意大利伊斯基亚岛地热发电厂的历史

摘要 已经发表了许多关于在 Larderello 进行地热资源开发的开创性活动的文章。然而，对于在拉德雷洛以南约 500 公里的意大利进行的同样开创性的活动，用于开发那不勒斯湾前的伊斯基亚岛上的温水的活动知之甚少。在这篇文章中，我们想分析自 1930 年代以来使热水发电成为可能的技术演变。有许多因素使这一开创性的发展成为可能。第一个与岛上现有的地质条件有关，第二个与钻井活动的演变有关，该活动已提供越来越多的热水和蒸汽。第三个与存在有关，在那不勒斯“费德里科二世”大学的工程学院里，他们的创造性思维已经设计并实现了二元流体系统的原型。从使用纯流体的 10 CV (1 CV = 0,98631 HP) 的小尺寸开始，到使用不混溶流体混合物的 300 kW 的尺寸。通过这种方式，他们已经预见到了这项技术的未来发展。文章分析了所有这些因素，以描述这种独特经验的诞生、发展和衰落，即使在我们今天也可以从中吸取有效的教训。达到 300 kW 的大小，使用不混溶的流体混合物。通过这种方式，他们已经预见到了这项技术的未来发展。文章分析了所有这些因素，以描述这种独特经验的诞生、发展和衰落，即使在我们今天也可以从中吸取有效的教训。达到 300 kW 的大小，使用不混溶的流体混合物。通过这种方式，他们已经预见到了这项技术的未来发展。文章分析了所有这些因素，以描述这种独特经验的诞生、发展和衰落，即使在我们今天也可以从中吸取有效的教训。
