Optimized Smart Grid Design with Integrated Hydrogen Storage for Sustainable Energy in Urban Areas

Abstract

The increasing demand for efficient and sustainable energy solutions has accelerated the development of smart grid systems by integrating different types of advanced energy storage technologies. Among various available solutions hydrogen storage is emerging as a key solution for addressing the variability of renewable energy sources while enhancing grid stability and energy efficiency. This research study investigates the design and optimization of smart grid systems with integrated hydrogen storage. The goal is to improve energy efficiency, enhance system resilience, and support the transition to near-zero energy buildings (NZEBs). The proposed system combines hydrogen storage with battery energy storage systems (BESS) to mitigate fluctuations in solar and wind power generation. A cloud-based monitoring and control system enables real-time data access, predictive maintenance, and optimal energy dispatch. The study also evaluates the environmental impact, energy efficiency, and economic feasibility. Results indicate that properly designed smart grid systems with hydrogen storage significantly enhance energy sustainability and reliability. The integration of hydrogen as a long-term storage solution reduces dependence on fossil fuels, accelerates NZEB development, and supports carbon neutrality goals. Hydrogen storage plays a crucial role in advancing renewable energy systems. The research provides insights into its potential as a key enabler in smart grid infrastructures, contributing to a more sustainable and resilient energy future. Nevertheless, this method has several drawbacks, such as a poor conversion rate and expensive infrastructure. Hydrogen synthesis through electrolysis usually has an efficiency of less than 70%, with further energy losses taking place during storage and fuel cell reconversion to electricity. Furthermore, a major obstacle to broad adoption is still the high upfront expenditures of fuel cells, storage tanks, and electrolysers. Notwithstanding these drawbacks, continued developments in electrolysis technology, better techniques for compressing hydrogen, and fuel cell cost reductions should increase viability. To support a more robust and sustainable energy future, this research addresses the present issues with hydrogen while also shedding light on its potential as a major facilitator in smart grid systems.
