Technology
Cryogenic compressed air to store energy
Higher efficiency, higher mobility
Our proprietary thermochemical process uses Temperature Swing Adsorption and direct-contact heat exchange to liquify and cryogenically store air discharged by a single-stage compressor.
When the system needs energy, the process vaporizes the liquid air before passing through a turbo-expander to generate electricity.
Our process works more efficiently by operating in a more favorable thermodynamic range.
