Summary

This master's thesis presents a comprehensive study of literature and a thermodynamic and economic assessment of different hydrogen storage solutions. The literature review provides a detailed overview of the current state of the art of hydrogen storage technology. The technical assessment involves the use of Phyton to code thermodynamic models of three hydrogen storage solutions and to address their technical performance such as energy density and energy intensity of the processes. The focus will be on compressed hydrogen storage, liquid hydrogen storage, and metal hydride. Afterwards, an economic analysis was performed to evaluate the CAPEX and the cost per unit of stored energy of each hydrogen storage solution analyzed previously. Finally, a multiattribute analysis has been conducted. The objective of the study is to provide a clear and detailed overview of hydrogen storage solutions, and an accurate assessment of the thermodynamic and economic indicators of three of the storages analyzed in the literature review, pointing out the one with the best techno-economic performance for further development and research intended for a future product for heating purposes of a 10-apartment residential building in Milan. The performed analysis has shown that compressed hydrogen represents the best alternative but its cost is still too high for small residential applications. The work has been conducted in collaboration with BDR Thermea which sells products in the Netherlands under the brand Remeha.
