Highview Power Storage designs and develops of large-scale energy storage for utility and distributed power systems. Using liquid air as the storage medium, Highview can design custom Liquid Air Energy Storage (LAES) plants, that can deliver around 5 MW or 15 MWh to significantly more than 50 MW or 200 MWh to service a growing multi billion dollar energy storage market.
Air turns to liquid when refrigerated to -196°C, and can be stored in standard insulated, but unpressurised vessels at very large scale. Exposure to ambient temperatures causes rapid re-gasification and a 700-fold expansion in volume, which drives a turbine and creates electricity.
Highview’s technology draws from established processes from the turbo-machinery, power generation and industrial gas sectors. The components of Highview’s processes can be readily sourced from large OEMs and have proven life times and performances.
In common with all energy storage systems, our LAES system comprises of three primary processes: a charging system; an energy store; and a power recovery. These can be scaled independently to optimize the system for different applications, a unique feature.
Why Liquid Air Energy Storage? Because it has:
- No geographical constraints
- Low capital cost
- Long lifetime 25+ years
- Scaleable to 100 MW and many GWhs
- Mature components available from a global supply chain
- Integration of industrial low-grade waste heat and waste cold
- Uses no scarce or toxic materials
