La costante crescita sociale e gli imminenti cambiamenti climatici impongono ormai una transizione energetica obbligata. La crisi energetica è a favore di quelle fonti rinnovabili che non fanno alcun affidamento sugli idrocarburi, e le strategie di neutralità carbonica includono, oltre alla produzione di potenza, anche approcci di decarbonizzazione in quei settori dove l’elettricità rinnovabile non può essere una soluzione. Per la desiderata transizione energetica, l’Idrogeno verde può essere un valido supplemento alla produzione di potenza sostenibile e una soluzione efficiente per i piani di decarbonizzazione. Inoltre, dato che la tecnologia si affaccia da poco tempo al mercato commerciale, la generazione della molecola è di ampio margine di miglioramento. In questa tesi si indaga Levelized Cost of Hydrogen (LCOH), il costo livellato di idrogeno verde in uscita da un impianto Power to Gas (PtG). L’attenta analisi sulla produzione d’idrogeno da impianti rinnovabili porta all’implementazione di un modello tecno-economico che mira al calcolo dell’LCOH di varie configurazioni, diverse sia in geografia che in caratteristiche d’impianto. Il modello è poi applicato a tre casi studio, casi che sono stati sviluppati in ambito di stage con Enel Green Power: impianto PtG nel sud della Patagonia, nell’ovest texano e nel sud Italia.

Abstract
The perpetual social growth and the imminent Climate Change require by now an obligatory energy transition. The energy crisis is in favor of those renewable sources that do not rely on hydrocarbons, and carbon neutrality’s strategies include, in addition to power generation, also decarbonization’s approaches in those sectors where renewable electricity cannot be a solution. For the desired energy transition, green hydrogen can be a valuable supplement to the production of sustainable power and an efficient solution for decarbonization plans. Furthermore, given that the technology has recently entered the commercial market, the generation of the molecule has a lot of room for improvement. This thesis investigates the Levelized Cost of Hydrogen (LCOH), it is the ultimate cost of hydrogen which is the output a Power to Gas (PtG) plant. The careful analysis of hydrogen production from renewable plants leads to the implementation of a techno-economic model that aims to calculate the LCOH of various configurations, different in both geography and plant characteristics. The model is then applied to three case studies, cases that were developed in the context of Internship with Enel Green Power: a PtG plant in southern Patagonia, western Texas and southern Italy.File | Dimensione | Formato | |
