What is ESS?

When asking ‘what is ESS’, you’re likely also asking the same question about BESS. You may even have seen the terms ESS and BESS used interchangeably. BESS simply stands for battery energy storage system. (I.e. energy stored in batteries.) On the other hand, ESS is just a general term for an energy storage system. Think of it like this.

What does ESS stand for in energy storage?

If you’ve read anything about energy storage, there’s a good chance you’ve come across ESS. But what is ESS, exactly? In short, ESS stands for energy storage system. It generally does what it says on the tin – stores energy which can then be discharged for later use. So, what are the different types of ESS? Is an ESS the same as a BESS?

What are some ESS systems?

Now, what are some of the important ESS systems? As the name suggests, this ESS converts renewable energy into mechanical energy, which is then stored in one of the following forms: pumped hydro (PHS), flywheel energy (FESS) or compressed air energy (AES).

How does ESS work?

ESS works by capturing energy during periods of low demand and releasing it during high demand. There are different ways to store the energy, these include thermal and electrochemical. Thermal energy storage relies on the capture and release of hot or cold.

What is the difference between ESS and Bess?

By utilising ESS, we can ensure that we have the energy available to balance out the grid, by releasing extra energy as required that has been stored up. While ESS refers to all storage technologies such as mechanical, thermal, and chemical. BESS, on the other hand, specifically refers to systems that store energy using batteries.

What are the advantages and disadvantages of ESS?

There are many advantages to utilising ESS. They maximise renewable energy, by storing excess energy and releasing it when needed. They help to save money through load shifting and reducing reliance on peak-hour energy costs.
