A key challenge in developing economies, such as India, is the limited access to electricity in rural areas due to distance from national power grids and challenging terrains like mountains or forests. To address this, there is a global shift towards utilizing Renewable Energy Sources (RESs) like solar, wind, small hydro, and biomass. These sources offer clean, affordable, and eco-friendly energy solutions, although they can be intermittent. The article emphasizes the potential of hybrid systems combining solar PV and wind technologies with energy storage systems. Green hydrogen is highlighted as a promising energy storage medium due to its ability to store energy over extended periods and its environmental benefits. However, the article notes the higher cost associated with green hydrogen production through water electrolysis. Hybrid Energy Systems (HES) are seen as essential for meeting the energy demands of developing nations, offering sustainable and dependable power supply. Optimizing HRES components and efficient energy management are crucial for enhancing reliability and efficiency. Overall, the focus is on harnessing renewable energy sources and innovative storage solutions to empower sustainable growth and address energy challenges in developing economies.
