Compressed-air and CO2 storage and Gas turbines and combined cycle

Energy flows from compressed-air and CO2 storage to gas turbines and combined cycle; their prices have moved together.

Compressed-air and CO2 storage (energy) and Gas turbines and combined cycle (energy): 2 relationships.

How they are linked

1. Energy flow

Physical flow · 29% of flow · Compressed-air and CO2 storage → Gas turbines and combined cycle

Compressed air feeds a turbine, often with gas firing.

• 29% of Compressed-air and CO2 storage's energy goes this way

2. Price link: expansion turbine

Cost and price · Weak · Both ways

Older plants burn gas in a turbine to expand the stored air, and newer designs use dedicated expanders. The turbine index shows little link to the compressor proxy, with monthly moves at 0.12 and yearly moves at 0.18.

• 0.12 monthly change correlation
• 0.18 12-month change correlation
• 1.90 fitted elasticity
