Storing energy in the air

Compressed Air Energy Storage (CAES) is a technology used for large-scale energy storage.

In times of excess electricity on the grid, massive amounts of energy from renewable sources can be stored by compressing air at high pressures in either an underground structure (e.g., salt cavern, aquifer, depleted gas) or an above ground storage system consisting of tanks or pipes.

Stored compressed air can be released and run through air turbines to generate power at times when demand is high (peak times and reduced output generated by wind turbines and/or solar plants).

MAN Diesel & Turbo offers numerous train solutions for the various diabatic, adiabatic, hybrid and isobaric CAES concepts.

MAN Diesel & Turbo offers the following solutions:

Axial Compressors: fixed or adjustable guide vanes

Centrifugal Compressor: barrel or split design

Radial Isotherm Compressor: with integrated intercoolers

Air Turbine: derived from steam turbine design

Expanders: as used in industrial processes
