The objective of the activity is to evaluate the potential and, in particular, the applicability in Italy of two innovative closed-loop<\/em> geothermal technologies:Eavor Loop<\/em>systems andWellBore Heat eXchangers<\/em>(WBHX).<\/p>\n <\/p>\n For both technologies, there is no need for a traditional geothermal reservoir<\/em>, instead wells are used in which a process fluid heats up without coming into direct contact with deep geological formations (heat exchange). Therefore, the proposed technologies can help to increase national geothermal producibility.<\/p>\n <\/p>\n The approach to the analysis of Eavor<\/em> technology began in the previous three-year research period, considering the first available technology configurations. Compared to previous versions, the new Eavor Deep<\/em> configuration, illustrated in the paper, can reach greater depths of up to 7 km. Like the previous configurations, it can be used in sedimentary rocks (sandstones or carbonates) and, additionally, in crystalline and metamorphic rocks.<\/p>\n <\/p>\n Having established the operational range<\/em> of the technology, both for thermal and electrical production, the analysis began in 2022 with the results of geothermal zoning of Italy produced during the three-year period 2019-2021. Two additional regions were identified on which to focus the analysis: Sardinia and Campania. In Sardinia, two areas with thermal anomalies were detected: the Anglona and Campidano areas, where 130\u00b0C is reached at a depth of 2000 m. The geological-geothermal analyses carried out in Campania identified the potential geothermal producibility for the region, considering as inputs<\/em> temperatures of 140\u00b0C within a depth of 5000 m: 157 municipalities were highlighted, falling in some sectors of the provinces of Salerno, Benevento, and Naples, for a total geothermal potential of about 1000 MWt.<\/p>\n <\/p>\n As far as wellbore heat exchangers are concerned, the analyses confirmed the possibility of reusing existing oil wells on the national territory: 842 wells were found to be potentially suitable (mainly concentrated in Lombardy, Emilia-Romagna, Marche, Abruzzo, Molise, Basilicata and Sicily). In addition, the Mazzara-Lippone concession in Sicily was chosen as a case study for assessing geothermal potential.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":185866,"id":185866,"title":"22014014","filename":"22014014.pdf","filesize":4733908,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2024\/02\/22014014.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/analisi-geologiche-a-supporto-della-fattibilita-geologica-dei-sistemi-geotermici-a-circuito-chiuso-e-degli-scambiatori-in-pozzo\/attachment\/22014014\/","alt":"","author":"93","description":"","caption":"","name":"22014014","status":"inherit","uploaded_to":185865,"date":"2024-02-09 10:43:29","modified":"2024-02-09 10:43:29","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2022-12-31","autori":"F.
