📋 Group Discussion Analysis Guide: Can Renewable Energy Storage Technologies Solve the Problem of Intermittent Power Supply?

🌐 Introduction to the Topic

Context Setting: Renewable energy sources like solar and wind have emerged as critical solutions to reduce greenhouse gas emissions and transition to a sustainable energy future. However, their intermittent nature poses challenges to reliable power supply, making storage technologies vital to bridging this gap.

Background: Intermittency refers to the fluctuating availability of energy due to natural variations in sunlight or wind. Advanced energy storage technologies, such as batteries, pumped hydro storage, and green hydrogen, offer potential solutions to stabilize energy systems.

📊 Quick Facts and Key Statistics

• Global Energy Storage Market: Valued at $13.6 billion in 2023; projected to reach $31 billion by 2030 (IEA, 2024).
• Battery Efficiency: Lithium-ion batteries achieve 90-95% round-trip efficiency, making them ideal for short-term storage.
• Pumped Hydro Contribution: Accounts for over 90% of global energy storage capacity, demonstrating its scalability.
• Renewable Energy Generation: Solar and wind contributed 12% of global electricity in 2023, highlighting growth but also variability.
