FREQUENTLY ASKED QUESTIONS

WHAT IS ENERGY STORAGE AND WHY IS IT IMPORTANT?

Energy storage refers to the capture and retention of energy for use at a later time. The importance of energy storage systems lies in their ability to balance supply and demand, ensuring a reliable power supply, particularly when dealing with intermittent energy sources like solar and wind. Effective energy storage solutions are vital for enhancing grid stability, reducing energy costs, and promoting the integration of renewable energies—the burgeoning demand for which underscores the critical role energy storage plays in achieving global sustainability targets.

Moreover, energy storage enhances resilience against potential power disruptions caused by unexpected spikes in demand or supply shortages. By acting as a buffer, energy storage systems allow for flexible responses to energy needs. The focus on developing scalable energy storage technologies is indicative of the pressing need to transition toward cleaner energy solutions while maintaining a dependable energy supply.

HOW DO ENERGY STORAGE SYSTEMS WORK?

Energy storage systems function through various technological processes designed to capture and release energy effectively. Most commonly, these systems employ batteries, pumping, or thermal storage techniques to store energy when it’s abundant and release it when demand peaks. For instance, electric batteries convert electrical energy into chemical energy for storage. When required, this stored energy can be converted back to electricity, supplying power to the grid or specific loads.

Mechanical energy storage relies on gravitational potential energy or kinetic energy for storage. In pumped hydro storage, water is elevated to a reservoir during low-demand periods and released to generate electricity during peak demand. Thermal energy storage systems utilize ice or molten salts to store energy in the form of heat, which can be released gradually for heating or transformed back into electricity. Collectively, these technologies provide flexible and effective solutions for energy management, contributing to a mature energy system.
