Abstract Hydrogen, the simplest and most abundant element in universe, is poised today to play a critical role transition toward clean energy future. This perspective article explores potential of hydrogen as sustainable carrier. First, historical modern applications across various sectors are examined. Then, delves into different methods for production. Since conventional fossil fuel‐based production raise environmental concerns, promising alternatives cleaner generation, including electrolysis powered by renewable energy, biomass gasification, photocatalytic reforming. The technical details advantages/disadvantages discussed, well ongoing research development efforts improve existing techniques make them more sustainable, efficient, cost‐effective. As world strives future, holds immense transformative role.

The global energy landscape is undergoing a significant transformation, driven by the need to reduce greenhouse gas emissions, enhance security, and provide sustainable clean power solutions. Renewable sources (RES) such as Solar Photovoltaic (SPV), wind, fuel cells, tidal play crucial role in this transition due their abundant availability low environmental impact. However, integrating these diverse into systems requires advanced control strategies ensure stability, efficiency, reliability. Existing systems, however, face challenges unstable voltage profiles, prolonged fault settling time (FST), high total harmonic distortion (THD), which compromise efficiency To overcome limitations, novel methodology proposed, PV cell, seven-level converter (SLC) system, named Four Level RES based SLC (FLRES-SLC) system. This system managed an Adaptive Neuro-Fuzzy Inference System (ANFIS), fine-tuned Cuckoo Search adopted Grey Wolf Optimizer (CS-GWO). hybrid strategy ensures robust profile, significantly reduces FST, lowers THD, thereby markedly improving overall performance of innovative approach offers reliable efficient solution for modern enhancing integration with ensuring high-quality delivery.
