What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

What is energy storage & why is it important?

Energy storage (ES) plays a key role in the energy transition to low-carbon economies due to the rising use of intermittent renewable energy in electrical grids. Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale.

What is advanced compressed air energy storage (a-CAES)?

They will run on an updated version of the technology called advanced compressed air energy storage (A-CAES). A-CAES uses surplus electricity from the grid or renewable sources to run an air compressor.

How many compressed air storage projects are there in the world?

For decades, there were only two operating compressed-air storage projects worldwide, at salt domes in Alabama and Germany. Another challenge is that those projects depend in part on natural gas.

Is compressed air energy storage a viable alternative to pumped hydro?

Another technology that's been in use for decades is compressed air energy storage (CAES), which can store energy on a grid scale and is billed as having the reliability of pumped hydro, without the same constraints on where you can build it.

Does Kansas have a compressed air energy storage Act?

For example, the state of Kansas has facilitated these processes with their Compressed Air Energy Storage Act , effective since 2009. A study that reports on promising locations, permitting processes and challenges, and mitigating solutions would help developers navigate these issues during the planning phase.
