Energy Storage

Introduction

Energy storage plays a crucial role in the utilization of non-conventional energy sources. It enables the efficient capture, storage, and utilization of energy, helping to balance energy supply and demand, and facilitating the integration of intermittent renewable energy sources.

Importance of Energy Storage

Energy storage is important for several reasons:

1. Need for storing energy from non-conventional sources: Non-conventional energy sources such as solar and wind are intermittent in nature. Energy storage allows the excess energy generated during peak times to be stored and used during periods of low energy production.

2. Balancing energy supply and demand: Energy storage helps to match energy supply with demand, ensuring a stable and reliable energy grid.

3. Enabling integration of intermittent renewable energy sources: Energy storage systems can store excess energy generated from renewable sources and release it when needed, reducing reliance on fossil fuels.
