Hybrid Renewable Energy Systems (HRES) for Off-Grid Rural Electrification: A Comprehensive Review of Components, Optimisation, and Real-World Applications

Navya Gupta, Dharsh Gujar, Khadija Bhanpurwala, Nilesh Balki, Sunil Bhil · 2026 · Indian Journal of Science and Technology

Summary. Hybrid renewable energy systems combining solar, wind, and biomass with storage technologies improve rural electrification in off-grid areas. Recent systems achieve 30-40% higher reliability, 10-25% lower costs, and 40-60% emission reductions compared to diesel alternatives. Key barriers include high upfront capital costs, battery degradation, and financing challenges. AI-based controls, hybrid battery-hydrogen storage, and digital twin technology enable better system optimization and predictive maintenance for scalable rural energy access.
