Hybrid Off-Grid Energy Systems Optimal Sizing with Integrated Hydrogen Storage Based on Deterministic Balance Approach

Incorporating diverse renewable energy sources is imperative for establishing a resilient and sustainable power infrastructure. This research explores the optimal techno-economical hybrid energy system configuration, emphasizing hydrogen energy for system balance. We introduce a novel DBM (Deterministic Balanced Method) to ascertain the annual energy output over the project’s lifespan, contrasting it with HOMER software results. Validation against HOMER Pro revealed a high consistency in our method, with differences within a 5% range. This indicates our approach’s reliability in determining hybrid energy system sizes accurately. In addition to harnessing solar radiation and wind data from NASA and METEONORM, our study encompasses a real-case evaluation of Cairo International Airport’s hybrid renewable energy systems. The system design is based on actual, researched loads. Our results not only offer insights into effective hybrid energy system sizing but also propose using surplus energy in distributed networks for industrial and transportation energy conversion applications.
