⚡ Renewable Energy Storage Solutions and the Intermittency Issue

🌍 Introduction to the Topic

Context Setting: Renewable energy sources, particularly solar and wind power, are critical to achieving global sustainability goals. However, their intermittent nature—solar panels generate energy only when the sun shines, and wind turbines depend on wind speed—poses significant challenges for consistent energy supply.

Background: The intermittency challenge has spurred global interest in energy storage technologies like batteries, pumped hydro, and thermal storage. These technologies aim to store excess energy during peak production for use during low production periods. With increasing global commitments to renewable energy, storage solutions are central to realizing a 24/7 renewable energy grid.

📊 Quick Facts and Key Statistics

• Global Renewable Energy Share: 29% of total electricity generation in 2023, with solar and wind accounting for 13%.
• Battery Storage Deployment: Global capacity exceeded 16 GW in 2023, with a projected growth to 30 GW by 2025.
• Cost of Lithium-Ion Batteries: Decreased by 89% since 2010, driving the adoption of battery energy storage.
• Energy Wastage: Nearly 10% of wind energy is curtailed annually due to storage limitations.
• India’s Ambition: Aiming for 500 GW of renewable capacity by 2030, relying heavily on storage solutions.

🧩 Stakeholders and Their Roles

• Governments: Policy frameworks, subsidies, and incentives for renewable and storage solutions.
• Energy Companies: Investment in R&D and deployment of storage technologies.
• Consumers: Adoption of distributed storage like home batteries.
