Abstract

Abstract: The potential role of hydrogen as a tool for the decarbonization of the energy sector is widely recognized. In this paper, a comprehensive analysis of the marginal utility of increasing the hydrogen penetration on the energy and environmental performances of a multi-energy system is developed to assess its potential. A distributed energy system satisfying the energy requirements for an existing building is chosen as test case, assumed as representative of a wide set of applications. Starting from real energy consumption profiles, representative scenarios and optimized design configurations are defined using a methodology that takes into account uncertainties both in demand and renewable production profiles and in techno-economic parameters assumptions. For each multi energy system configuration, an optimal dispatch control strategy is achieved through a mixed-integer linear programming method to maximize the building self-independence from the grid. Results show how an increase of hydrogen technologies penetration allows a reduction of the specific carbon footprint of the system down to 100 grCO2 /kWh while increasing the system resilience up to 85%. Detailed information about the marginal effect of H2 technologies on resilience, carbon footprint, and fossil energy savings are presented and can be used for extensions to similar applications. Highlights: Resilience up to 85% is achieved through hydrogen integrated multi-energy system. Specific carbon footprint is reduced up to 100grCO2 /kWh. Uncertainties are accounted through a coupled clustering-Montecarlo approach. Hydrogen seasonal storage is crucial for decarbonization of the energy system.
