How much does compressed air energy storage cost?

Our base case for Compressed Air Energy Storage costs require a 26c/kWh storage spread to generate a 10% IRR at a $1,350/kW CAES facility, with 63% round-trip efficiency, charging and discharging 365 days per year.

What is compressed air energy storage (CAES)?

What opportunities? Compressed Air Energy Storage (CAES) seeks to smooth out power grids, using excess electricity to compress air into storage tanks or underground reservoirs at high pressures (e.g., 40-80 bar). The energy needed to compress air to different temperatures is plotted below.

How much does stored electricity cost?

A number of recent techno-economic studies have estimated CAES-based stored electricity costs at $0.15 to $0.60/kWh , . The Framework Study identifies promising RD&D pathways to reduce the levelized cost of storage (LCOS) of key storage technologies.

What are the main components of a compressed air system?

The largest component in such systems is the storage medium for the compressed air. This means that higher pressure storage enables reduced volume and higher energy density.
