What are the non-battery energy storage projects

Are flow batteries a good choice for energy storage?

Flow batteries, which use liquid electrolytes, are also becoming popular for large-scale, long-duration energy storage, particularly in grid applications. These innovations are critical as they provide diversified options for energy storage, reducing dependency on any single technology or material.

What is gravity based energy storage?

The gravity-based system mentioned above has been devised by a company called Energy Vault. It uses the energy produced when renewable generation is high to raise 30-tonne bricks into the air inside a special building. Why? Well, elevating the bricks results in them storing what is known as potential energy.

Why is energy storage important?

This makes energy storage increasingly important, as renewable energy cannot provide steady and interrupted flows of electricity – the sun does not always shine, and the wind does not always blow. As a result, we need to find ways of storing excess power when wind turbines are spinning fast, and solar panels are getting plenty of rays.

Why is the EU's Strategic Action Plan on batteries important?

These innovations are critical as they provide diversified options for energy storage, reducing dependency on any single technology or material. In Europe, the EU's Strategic Action Plan on Batteries is promoting the development of innovative, non-lithium technologies to ensure Europe remains a leader in the global battery market.

Why do we need scalable energy storage solutions?

The IEA emphasises the need for scalable energy storage solutions to enhance grid reliability and support the integration of variable renewable energy sources.

Will battery storage grow in 2025?

In the United States, the 2022 introduction of the Inflation Reduction Act included an investment tax credit for stand-alone storage. Since then we have seen huge growth in the sector in the US, and we expect to see this to continue into 2025, with several large-scale battery storage projects set to complete in 2025.
