Energy hubs are essential for reliable and sustainable energy access across sectors, but they face increasing cyber threats, especially in demand-side applications. This study proposes a K-Nearest Neighbors (KNN) approach to secure demand-side load data. Energy hubs are evolving to optimize energy generation, distribution, and consumption, integrating various energy forms and storage solutions like hydrogen. Hydrogen integration supports decarbonization, operational flexibility, and resilient energy infrastructure. While traditional EH models often focus on a single energy carrier, the incorporation of hydrogen in EHs revolutionizes energy management, offering clean and versatile energy options. The article emphasizes the role of hydrogen in grid balancing, seasonal storage, and its integration with fuel cells, vital for modern energy hubs' design. By utilizing renewable energy sources, EHs promote low-carbon operations and contribute to sustainable energy transitions. The article highlights the importance of energy storage devices in EHs for managing energy supply and demand efficiently. As EHs become more interconnected and intelligent, the integration of hydrogen and storage technologies is explored for economic benefits. Despite advancements, EHs are vulnerable to cyber threats, requiring innovative strategies like data science and machine learning for protection.
