An Energy Balance and Multicriteria Approach for the Sizing of a Hybrid Renewable Energy System with Hydrogen Storage


As the clamour for a Net Zero carbon energy economy increases, it is necessary to harness the potential of renewable energies in powering buildings to lower fossil power plants' contributions to the overall energy mix. This paper aims to present an energy balance load sensitivity analysis and multi-criteria method for sizing a green energy system for powering two office complexes that house space research laboratories. The energy component considered includes battery storage (BAT), captive diesel generator (DG), fuel cell (FC), hydrogen storage (H2T), solar photovoltaic (PV), and wind turbine. Using HOMER, the techno-economic features and the hourly operational details of the energy components were obtained. The efficacy of Entropy- Additive Ratio Assessment was deployed on the outputs from HOMER to obtain the most preferred energy system based on more than one criterion. The result of the study indicates that the most preferred energy system for Abuja is a PV, WD, FC, DG, and BAT, having a total net present cost (TNPC) of $220,930. In contrast, the most suitable energy system for the energy in the Anyigba office consists of PV, FC, and BAT, with its TNPC at $106,955.
