Small energy storage project introduction

What is electrical energy storage (EES)?

Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price.

When was the first electricity storage system invented?

The first electrical energy storage systems appeared in the second half of the 19th Century with the realization of the first pumped-storage hydroelectric plants in Europe and the United States. Storing water was the first way to store potential energy that can then be converted into electricity.

What is energy storage technology?

The development of thermal, mechanical, and chemical energy storage technologies addresses challenges created by significant penetration of variable renewable energy sources into the electricity mix.

How can energy storage improve the performance of the energy system?

Energy storage technologies can significantly improve the performance of the whole energy system. They enhance energy security, allow more cost-effective solutions, and support greater sustainability, enabling a more just energy system.

What is the business model for energy storage?

The business model for energy storage reli es on value stacking, providing a set of services for customers, a local utility, and the grid. By having two or three distinct contracts stacked on top of each other, you can generate multiple revenue streams.

How is thermal energy stored?

Thermal energy is stored solely through a change of temperature of the storage medium. The capacity of a storage system is defi ned by the specifi c heat capacity and the mass of the medium used. Latent heat storage is accomplished by using phase change materials (PCMs) as storage media.
